Dear Governor and Legislative Leaders:
As requested by the Joint Legislative Audit Committee, the California State Auditor presents this audit report
concerning the California Public Utilities Commission’s (commission) oversight of utility balancing accounts of
entities it regulates.
This report concludes that the commission lacks adequate processes to provide sufficient oversight of utility
balancing accounts to protect ratepayers from unfair rate increases. State law directs the commission, whenever it
authorizes any rate change that includes costs passed on to customers, to require utilities to establish a balancing
account. A balancing account is a tracking mechanism used to ensure that a utility recoups from ratepayers costs
the commission has authorized and that ratepayers do not pay more than they should. If a balancing account has
a balance—indicating an over‑ or under‑collection from ratepayers—the utility will generally seek periodically
to adjust future rates to either refund or recoup the balance. State law requires the commission to review
semiannually certain balancing accounts; however, it does not otherwise require the commission to review all
balancing accounts. Currently, the commission only reviews some balancing accounts when a utility requests to
incorporate the balance in that account into future rates as a surcharge or a credit. This practice does not ensure
that the commission adequately reviews balancing accounts to protect ratepayers from unreasonable rates.
Although the commission relies on the Office of Ratepayer Advocates (Ratepayer Advocates)—an independent
office within the commission—to review energy utility balancing accounts, this reliance is misplaced because
Ratepayer Advocates is not required to review all energy utility balancing accounts. Ratepayer Advocates
primarily focuses on balancing accounts that energy utilities include in formal proceedings, which resulted in it
reviewing only 58 percent of the value of large energy utilities’ balancing accounts active during 2009 through
2011. It did not review other balancing accounts with a value of $37.6 billion during this period.
Given that balancing accounts directly affect rates that a utility charges ratepayers and given the broad authority
the commission has to inspect and audit utilities’ books, accounts, and records, we believe that the commission
should use a systematic process that ensures a review of all those balancing accounts that can have the most
impact on ratepayers. However, the commission lacks the necessary information, such as the size of a balancing
account and the last time it was reviewed, to determine which balancing accounts it should review. In addition
to not providing adequate oversight over balancing accounts, the commission has not always complied with a
requirement to audit utilities’ books and records according to the schedule prescribed by state law. Also, for
over three decades, it has not provided the results of these audits to the California State Board of Equalization
(Equalization) for tax assessment purposes, as required by state law. Although Equalization believes that this
requirement is no longer appropriate, neither Equalization nor the commission has sought to change the law.
Respectfully submitted,

informal filings, the commission’s Division of Water and Audits
(water division) and Ratepayer Advocates perform a more detailed
review of some balancing accounts when the utilities file for a
formal or informal proceeding to refund or recoup their balances.
We noted, however, that the commission lacks adequate processes

ratepayers from unfair rate increases. The commission relies on

utilities (electric, natural gas, or both). However, Ratepayer
Advocates only reviews those energy utilities’ balancing accounts
that are included in certain formal proceedings before the
commission. Specifically, Ratepayer Advocates reviewed only
23 percent of large energy utilities’ balancing accounts active during
2009 through 2011, representing 58 percent of the dollar value
of these balancing accounts. It did not review other balancing
accounts that had a total value of $37.6 billion during this period.
Given that balancing accounts directly affect rates that a utility
charges ratepayers and given the broad authority the commission
has to inspect and audit utilities’ books, accounts, and records, we
believe that the commission should use a systematic process that
ensures a review of all those balancing accounts that can have the
most impact on ratepayers. However, the commission does not
have the necessary information, such as the size of the balancing
account and the last time the commission reviewed it, to help
determine which balancing accounts it should review. Although the
commission obtained this information from the utilities upon our
request, we found omissions and errors in that information, which
will limit its usefulness as a monitoring tool.
In addition to the commission lacking an adequate review process,
Ratepayer Advocates’ process for performing these reviews
had weaknesses. Of the 18 reviews of balancing accounts we
examined, only two had sufficient documentation to demonstrate
the procedures that Ratepayer Advocates performed. The other
16 reviews were either poorly documented or not documented
at all. The lack of documentation for many of the 18 reviews may
be caused in part because Ratepayer Advocates does not require
supervisors to formally approve analysts’ reviews of balancing
accounts. Instead, supervisory approval happens during informal
discussions about the conclusions analysts have reached in a review
without examining the actual work the analysts performed. We
believe that a documented supervisory review is necessary to assure
Ratepayer Advocates management and other stakeholders that the
analyst has performed all planned procedures appropriately and
that any reductions in recovery amounts that the analyst may be
proposing are accurate. In contrast, most of the water division’s
reviews of balancing accounts that we tested had appropriate
documentation and had received formal approval from a supervisor.
We also found the commission does not audit the accounting
records of the utilities it regulates according to the schedule
prescribed by state law: every three years for those utilities
that serve more than 1,000 customers and every five years for
those utilities that serve 1,000 or fewer customers. The intent
of the law is to ensure that the commission regularly audits all
utilities to increase public confidence in the regulatory process.
California State Auditor Report 2013-109 3
March 2014
The commission generally complies with the audit requirement
through procedures it performs during the review of a utility’s
general rate case. However, the commission does not ensure
that all utilities file a general rate case every three or five years to
coincide with the audit requirement. Specifically, the commission
has allowed five energy utilities with more than 1,000 customers
to file their general rate cases beyond a three‑year cycle, and it
has allowed another small energy utility to adjust rates through
informal filings without a general rate case. Further, because it
only requires the 10 largest water utilities to file their general rate
case every three years, more than half of the remaining 106 water
utilities had not filed their general rate cases in time to coincide
with the audit requirement in state law. As a result, the commission
is not ensuring that it audits these utilities within the time frames
the law requires.
Finally, the California State Board of Equalization (Equalization)
believes that the law requiring the commission to provide audit
reports to Equalization is out of date. Specifically, state law requires
the commission to provide its audit reports on utilities’ accounting
records to Equalization for use in assessing taxes on those utilities.
However, the commission has not done so in over three decades.
Equalization stated that the commission’s general rate cases do not
focus on the same components of a utility’s operations and finances
as assessment of taxes requires. Further, Equalization told us that
it assesses taxes on many more companies than those that the
commission regulates. Equalization has established its own process
to audit all companies, including utilities, in the State and believes
that it is in a better position to carry out this function than the
commission. Equalization believes that requiring the commission
to do the work necessary to allow Equalization to assess taxes on
utilities may not be cost‑effective for the State. The director of the
energy division noted that the commission has not taken a position
on whether to change the existing law. Although Equalization
believes that the law should be revised to remove the requirement
that the commission provide its audit reports to Equalization for tax
assessment purposes, neither of them has sought to change the law.
Recommendations
To ensure proper oversight of balancing accounts, the Legislature
should amend California Public Utilities Code, Section 792.5,
to require the commission to develop a risk‑based approach for
reviewing all balancing accounts periodically to ensure that the
transactions recorded in the balancing accounts are for allowable
purposes and supported by appropriate documentation, such
as invoices.
4 California State Auditor Report 2013-109
March 2014
To ensure that it has the necessary information to provide
appropriate oversight of the balancing accounts of regulated
utilities and thus protect ratepayers from unfair rate increases, the
commission should regularly update the list of balancing accounts
that it authorized and verify its accuracy. Both the commission
and Ratepayer Advocates should use this list to guide their
oversight efforts.
To ensure that it efficiently and effectively monitors energy utilities’
balancing accounts to protect ratepayers from unfair rate increases,
the commission should direct its energy division to perform
in‑depth reviews of balancing accounts that Ratepayer Advocates
has not reviewed.
Both Ratepayer Advocates and the water division should, within
six months, develop policies to ensure that reviews of balancing
accounts are appropriately documented, subjected to supervisory
approval, and retained.
The commission should follow the state law requirement to inspect
and audit the accounting records of utilities it regulates within
required time frames.
The Legislature should amend state law to remove the requirement
that the commission provide audit reports to Equalization.
Agency Comments
Although Ratepayer Advocates disagreed with some of our
conclusions, both it and the commission agreed with our
recommendations and plan to implement them.

Introduction
Background
The California Public Utilities Commission (commission) is
responsible for ensuring that California utility customers have
safe, reliable utility service at reasonable rates, for protecting utility
customers, and for promoting the health of California’s economy.
The commission consists of five members appointed by the
governor and approved by the Senate. Along with supporting staff,
it regulates all investor‑owned utilities (utilities) in the State and
is responsible for authorizing the rates these utilities may charge
ratepayers. It has broad authority, including the authority to inspect
and audit the records of regulated utilities at any time. As of 2013
there were six electric, seven natural gas, and 116 water utilities
regulated by the commission in California that served 11.5 million,
10.7 million, and 6.8 million customers, respectively. As Figure 1
shows, the commission has several divisions. The Energy Division
(energy division) and the Division of Water and Audits (water
division) are responsible for ensuring that utilities comply with
commission directives, among other duties. The commission also
includes the Office of Ratepayer Advocates (Ratepayer Advocates),
an independent office whose director is appointed by the governor;
it was established to represent the interests of public utility
customers, with the goal of obtaining the lowest possible rate for
service consistent with reliable and safe service levels. State law
provides Ratepayer Advocates independent authority to review the
records of regulated utilities during rate‑setting proceedings.

6 California State Auditor Report 2013-109
March 2014
Utilities Establish the Rates Charged to Consumers Through a General
Rate Case Proceeding
The commission authorizes the rates that utilities may charge their
customers through a process known as the general rate case, which
typically occurs every three years. Rate setting is a complex process:
utilities present their financial records to the commission as well
as their proposed rates, which are based on the differing costs of
serving various customer classes, on certain statutory requirements,
and on public policy reasons for charging different rates per unit.
As Figure 2 shows, when developing its proposed rates, a utility
presents costs in three main categories: capital costs, fixed‑budget
costs, and pass‑through costs. The commission allows utilities to
make a certain level of profit on capital costs, which represent the
utilities’ investment in the infrastructure and equipment used to
provide electricity, natural gas, or water to consumers, such as a
power plant or a pipeline for natural gas or water. For fixed‑budget
costs, the commission generally authorizes a budget for the
utility to recoup the costs that it can reasonably control, such as
administration costs. The utility must absorb any fixed‑budget
costs it incurs that are in excess of the authorized budget, but
if costs are under budget, it keeps the amount saved as profit.
Finally, for pass‑through costs, which are costs that are difficult to
reasonably predict, such as costs of purchasing electricity, natural
gas, or water, the commission allows the utility to recoup, through
rates and without any mark‑up, all costs the utility incurs. These
three types of costs, including allowed profit margins on capital
costs, are incorporated into the rate that the utility proposes to
collect from different classes of ratepayers.
After the commission has determined the total amount it will
authorize the utility to recover from its customers based on the
cost to provide services, the next step is to develop a per unit rate
(for example, cents per kilowatt‑hour for electricity). However,
the cost of serving customers in different classes can vary. For
example, some large industrial customers may receive electrical
service directly from a transmission line without using additional
utility infrastructure, resulting in a lower rate than residential
customers who need intermediary utility infrastructure, such as
substations and distribution lines, to receive electricity. To reflect
these differences in costs, the commission approves different rates
for customer classes. The utilities develop these rates based on
their forecasts of sales and costs, then they propose the rates to
the commission.

When a utility files a general rate case, the commission, its staff,
Ratepayer Advocates, and other advocacy groups review the costs the
utility presents to ensure that the costs are necessary, reasonable, and
fair. During the general rate case process, Ratepayer Advocates reviews
the utility’s accounts, past and projected expenses, revenue forecasts,
capital costs, and plant additions; and it may protest the utility’s
proposed rates on behalf of the ratepayers. Moreover, individuals
and groups that represent the interest of ratepayers, businesses, and
special interests known as interveners, may also provide testimony
to the commission regarding proposed rates. These parties may
reach an agreement with the utility to adjust its proposed rates. The
commission ultimately authorizes the rates the utility may charge its
customers after hearing testimony from all involved parties. Because
a utility presents numerous documents to justify its proposed rates
and because of the time required for the parties to review those
documents and to reach an agreement on any adjustments to the
8 California State Auditor Report 2013-109
March 2014
proposed rates, the general rate case may last as long as 18 months. As
a result, a utility typically files for the general rate case well in advance
of the date the proposed rate would become effective in order to help
ensure that it receives commission approval on time. If the commission
does not approve the proposed rate before it is due to become effective,
the utility may charge ratepayers an interim rate based on the most recent
commission‑approved rate adjusted for inflation and then recoup or
refund the difference between the interim and final rate from ratepayers
after the commission has authorized the final rate.
The Commission Requires That Utilities Track Certain Costs and Related
Revenues Using Balancing Accounts
State law requires the commission to direct utilities to track specific types
of costs and related revenues from customers using a tracking mechanism.
This tracking mechanism—known as a balancing account—protects
ratepayers and utilities by identifying any under‑ or over‑collection of
revenue from ratepayers compared to the utilities’ actual allowed costs.
Because the rates that the commission approves are predicated on
projected costs of the utility and projected consumption by ratepayers,
both the utilities and the commission have a vested interest in determining
the actual costs and revenues related to certain components to determine
whether the utility under‑ or over‑collected from ratepayers. For example,
the price of natural gas that a gas utility purchases for its ratepayers can
fluctuate widely in a short time. Thus, the actual cost that a utility incurs
to purchase natural gas can vary from the cost that the utility projected
and incorporated into the authorized rate. Because a natural gas utility
can only collect from ratepayers up to the price it paid for the purchase of
natural gas, the cost of purchasing natural gas and related revenue from
ratepayers must be tracked to ensure that the utility recovers its costs and
ratepayers do not pay more than the utility’s costs.
Before setting up a balancing account, a utility must file a statement that
details the purpose of the balancing account and the types of costs or
revenue to be tracked in the account with the commission for approval.
This statement also details the specific accounting procedures the utility
must perform to record a transaction in this balancing account.
The Commission Generally Reviews Balancing Accounts When a Utility
Wishes to Incorporate the Balance of an Account Into Future Rates
To the extent that a balancing account has a balance, reflecting either
over‑ or under‑collection of revenue from ratepayer charges compared
to authorized costs, the utility will periodically incorporate the balance
into future rates by providing a reduction or an increase to future rates.
Although a utility typically incorporates the balances in these accounts
into future rates when it files for a general rate case, at other times it
California State Auditor Report 2013-109 9
March 2014
may request a rate adjustment to reflect the balance by filing an advice
letter, which is an informal filing, or by filing a formal application for
certain proceedings. The commission noted that allowing a utility to
incorporate the balance in a balancing account into future rates before
the next general rate case, can mitigate sudden large swings in rates for
ratepayers by making smaller changes to the rates more frequently.
The commission provides specific guidance on when the utilities can
incorporate a balance into future rates. A large water utility, one with
more than 10,000 service connections, may choose to incorporate the
balance in an account into future rates using an informal process by
filing an advice letter with the commission’s water division when the
balance exceeds 2 percent of the utility’s total annual gross operating
revenue. A smaller water utility, one with 10,000 or fewer service
connections, is required to file an advice letter at any time before its
next general rate case if the balance in one of its balancing accounts
exceeds 2 percent of the utility’s total annual gross operating revenue.
Those advice letters, filed with the water division, contain such
information as the total balance in the account, the amount of the
credit or surcharge the utility wishes to add to future rates, and other
supporting documents. After the water division approves the advice
letter, the utility adds the credit or surcharge to its rates.
An energy utility—electric, natural gas, or both—can also use the
informal process by filing an advice letter with the energy division.
However, unlike a water utility, an energy utility is generally not
subject to a similar threshold and it may choose to file an advice
letter to incorporate the balance into future rates at any time it deems
necessary before its next general rate case.
An electric utility also presents certain costs, such as those for fuel and
purchased power, twice each year to the commission through formal
proceedings known as Energy Resource Recovery Account (ERRA)
proceedings. In the first ERRA proceeding, the utility presents its fuel
and purchased power forecasts to the commission for review. In the
second ERRA proceeding, the utility submits balancing accounts, such
as the utility’s designated ERRA balancing account, to incorporate
their balances into future rates. Similarly, a natural gas utility must
incorporate into future rates the balances in certain balancing accounts
through two separate formal proceedings before the commission.
Specifically, it must annually file an application for the Gas Procurement
Incentive Mechanism proceeding, which allows the commission to
review the utility’s natural gas purchasing activities to ensure that it is
obtaining the best prices. In addition, a natural gas utility must file an
application for either the Biennial Cost Allocation Proceeding or the
Triennial Cost Allocation Proceeding. These proceedings address
the way the utility allocates its costs for providing services to customers.
An energy utility can choose to include balancing accounts during these
proceedings as a means to incorporate any balances into its rates.
10 California State Auditor Report 2013-109
March 2014
State law grants the commission authority to inspect the accounts,
books, papers, and documents, including balancing accounts, of
any public utility at any time. In addition to giving the commission
this authority, state law also gives Ratepayer Advocates access to any
information from public utilities that it deems necessary to perform
its duties. State law requires the commission to audit the books and
records of all utilities it regulates every three or five years depending
on the number of customers a utility serves and to provide these
audits to the California State Board of Equalization for tax assessment
purposes. Although state law requires the commission to review power
procurement balancing accounts semiannually, commonly referred
to as ERRA, there is no requirement for the commission or Ratepayer
Advocates to specifically review other balancing accounts. The energy
division and the water division, as well as Ratepayer Advocates, review
balancing accounts that a utility includes in informal advice letters or
applications for formal proceedings, and they may request that the utility
provide additional support to verify the costs and revenues charged to
each balancing account included in these filings. As Table 1 shows, the
details included in these reviews vary based on the entity performing
the review and the purpose of the review.
The energy division is responsible for reviewing all filings by energy
utilities to ensure that the utilities are complying with commission
decisions, including making changes to the utility rates based on
under‑ or over‑collection in a balancing account before the next
general rate case. This review includes verifying that the utility has
appropriate authorization to file for rate adjustment, and the energy
division may request additional information from the utility if the
balance is very large. However, when reviewing those informal
filings requesting a change to rates, the energy division does not
verify the accuracy or appropriateness of the costs that the energy
utility has charged to the balancing account by reviewing detailed
documentation, such as invoices. On the other hand, the commission’s
water division, which is responsible for reviewing informal filings by
water utilities, does verify the accuracy and appropriateness of the
costs the utility has charged to the balancing account.
Ratepayer Advocates reviews balancing accounts for both water
and energy utilities during informal and formal filings. In reviewing
informal filings by a water utility, Ratepayer Advocates may initially
complete a high‑level review of the balancing accounts included in
the filing, and it may complete a more comprehensive review if the
initial review raises any concerns. While Ratepayer Advocates reviews
the informal filings by energy utilities only to ensure that the balances
and proposed changes to the balances they included in the filing are
reasonable, its oversight efforts are focused on the formal proceedings,
during which it completes a more comprehensive review of all of the
balancing accounts the energy utility includes during that proceeding.

Scope and Methodology
The Joint Legislative Audit Committee (audit committee)
directed the California State Auditor to audit the commission’s
policies and procedures for overseeing the balancing accounts of
the utilities it regulates. The analysis the audit committee approved
contained seven separate objectives. We list the objectives and the
methods we used to address them in Table 2.

Assessment of Data Reliability
In performing this audit, we obtained electronic data files the
commission received from the utilities it regulates identifying
the balancing accounts active during 2004 through 2012. The
U.S. Government Accountability Office, whose standards we
follow, requires us to assess the sufficiency and appropriateness
of computer‑processed information that we use to support our
findings, conclusions, or recommendations. We did not perform
accuracy and completeness testing of these data because the source
documents required for this testing are maintained by utilities
located throughout the State that provided the information to the
commission, making such testing cost‑prohibitive. Consequently,
we determined that the data were of undetermined reliability for
the purpose of identifying all balancing accounts the commission
authorized during 2004 through 2012. However, as we discuss in
the Audit Results, we identified certain concerns with the data
based on limited comparison of these data against the records of
the commission and of Ratepayer Advocates.

Audit Results
The California Public Utilities Commission Does Not Have Adequate
Processes for Monitoring Utility Balancing Accounts
The California Public Utilities Commission (commission) lacks
adequate processes for sufficient oversight of balancing accounts to
protect ratepayers from unfair rate increases. Given that balancing
accounts directly affect rates that a utility charges ratepayers and
given the broad authority the commission has to inspect and
audit utilities’ records, we believe that the commission should
use a systematic process that ensures a review of those balancing
accounts that can have the most impact on ratepayers. Currently,
the commission only reviews balancing accounts when a utility
requests to revise the future rates to recoup or refund the balance
in the balancing account. Moreover, the commission relies on the
Office of Ratepayer Advocates (Ratepayer Advocates) to review
balancing accounts of energy utilities (electric, natural gas, or both),
but Ratepayer Advocates only reviews the balancing accounts of
energy utilities that are included in certain formal proceedings
before the commission. During 2009 through 2011, Ratepayer
Advocates reviewed only 58 percent of the authorized amounts for
the balancing accounts of the six largest energy utilities, leaving
balancing accounts with a total value of $37.6 billion unreviewed.
Further, the commission lacks the necessary information, such
as the size of the account and the last time the commission
reviewed it, to help identify those balancing accounts that are
good candidates for review. Although the commission obtained
this information from the utilities upon our request, the omissions
and errors we found in the information will limit its usefulness as a
monitoring tool.
The Commission Has Not Reviewed Many Large Balancing Accounts for
Energy Utilities
State law directs the commission, whenever it authorizes any rate
change that includes costs passed on to customers, to require
utilities to establish balancing accounts so that any under‑ or
over‑collection of payments from ratepayers is appropriately
incorporated into future rates as a surcharge or a credit. A state law
requires the commission to review semiannually certain balancing
accounts called power procurement balancing accounts, which
are commonly referred to as Energy Resource Recovery Accounts
(ERRA) and which track the difference between a utility’s forecasted
and actual costs to procure electricity for its customers. However,
state law does not otherwise expressly require the commission to
review other balancing accounts although it does authorize the
commission to review utilities’ records in the context of rate‑setting
16 California State Auditor Report 2013-109
March 2014
procedures. Moreover, state law authorizes the commission, at any
time, to inspect and audit utilities’ books, accounts, and records,
which would include balancing accounts. Thus, given the commission’s
important responsibility to monitor balancing accounts to ensure that
ratepayers are fairly charged and that utilities are fairly compensated,
and in light of the broad authority granted to the commission to
review utilities’ records, we believe the commission should adopt a
process to provide more thorough oversight of balancing accounts
through a risk‑based approach.
The commission’s current Currently, the commission only reviews balancing accounts when a
practice for reviewing balancing utility requests to incorporate the balance in that account into future
accounts when a utility requests rates as a surcharge or a credit. This practice does not ensure that
to incorporate the balance in the commission adequately reviews balancing accounts to protect
that account into future rates ratepayers from unreasonable rate increases. For example, utilities
as a surcharge or a credit does have an incentive to file more quickly with the commission to recover
not protect ratepayers from the under‑collections reflected in their respective balancing accounts
unreasonable rate increases. as this will result in an increase in their rates. On the other hand, for
balances that utilities would need to refund to their ratepayers through a
reduction in rates, less incentive may exist for the utilities to file quickly.
Although it has a clear authority to review balancing accounts, as a
result of its current practice, the commission has not reviewed many of
the balancing accounts it has authorized over the past three years. The
Energy Division (energy division), which has oversight responsibility for
energy utilities, does not review balancing accounts in detail. Instead,
as we show in Table 1 on page 11, the energy division performs several
high‑level procedures that do not provide the assurance that a detailed
review would provide. According to the commission, the energy
division’s higher‑level review is acceptable because Ratepayer Advocates
examines balancing accounts dealing with procurement costs in depth
each year. Therefore, the commission relies on Ratepayer Advocates to
review energy utility balancing accounts rather than having the energy
division perform these reviews.
However, the commission’s reliance is misplaced as Ratepayer
Advocates’ reviews do not focus on all energy utility balancing accounts.
As we discuss in the Introduction, Ratepayer Advocates focuses only on
certain formal proceedings, such as the ERRA proceeding for electric
utilities and the Gas Procurement Incentive Mechanism and Biennial
or Triennial Cost Allocation proceedings for natural gas utilities,
which it considers to have the most impact on consumer utility rates.
The commission requires energy utilities to request to incorporate the
balances in certain balancing accounts into future rates through these
formal proceedings. An energy utility may, at its discretion, include
other balancing accounts in an ERRA proceeding. Ratepayer Advocates
asserted that by focusing on the balancing accounts included in these
proceedings, it covers the balancing accounts that are most significant
to its mission to reduce utility rates for customers consistent with
California State Auditor Report 2013-109 17
March 2014
reliable and safe service levels. However, Ratepayer Advocates does
not have a formal policy for identifying the balancing accounts that
it believes are most significant; instead, it considers whether a review
would be beneficial for making a case for a lower utility rate.
Ratepayer Advocates also asserted that it is reviewing the majority
of authorized amounts in balancing accounts. However, our review
found that the number and dollar value of the balancing accounts
that Ratepayer Advocates reviewed varied considerably among
the six largest energy utilities. As Table 3 shows, only 23 percent
of these utilities’ balancing accounts active during 2009 through
2011—representing 58 percent of the costs and related revenues being
tracked in all authorized balancing accounts—were subject to review.
Further, among the six utilities, the number and value of the reviewed
balancing accounts differed significantly. For example, as shown in
Table 3, Ratepayer Advocates reviewed more than half of Southern
California Edison’s (Edison) balancing accounts, representing
94 percent of the dollar value of these accounts. In contrast, Ratepayer
Advocates reviewed 5 percent of the balancing accounts for Pacific
Gas and Electric Company (PG&E), which represent only one‑third of
the costs and related revenues being tracked through its electric utility
balancing accounts. For the other energy utilities and PG&E’s natural
gas utility, the dollar value of the balancing accounts that Ratepayer
Advocates reviewed ranged from 27 percent to 79 percent.

Although some of the individual balancing accounts that
Ratepayer Advocates did not review were relatively small in
value, together those balancing accounts not reviewed tracked
authorized costs and related revenues totaling $37.6 billion, or
42 percent of the value of the energy utilities’ balancing accounts
existing during 2009 through 2011. For example, in 2011 PG&E
had more than $601 million in outstanding balances in its electric
balancing accounts that Ratepayer Advocates did not review, an
amount that may be passed on to customers in future rates. Table 4
shows that Ratepayer Advocates did not review some accounts that
tracked as much as $9.1 billion in authorized amounts during 2009
through 2011. Because of the large authorized amounts, as well as
the balances that utilities will pass on to ratepayers, these balancing
accounts have significant potential to affect rates.

California State Auditor Report 2013-109 19
March 2014
Ratepayer Advocates’ inconsistent level of review results from its
focus on certain formal proceedings, primarily those related to
ERRA filings, which vary considerably among the electric utilities in
the value of the balancing accounts. For example, Edison included
more balancing accounts than PG&E in formal filings Ratepayer
Advocates reviewed. When presented with the results shown
in Table 3 on page 17, Ratepayer Advocates could not explain
how reviewing far more balancing accounts for Edison than for
other electric utilities furthered its mission. However, Ratepayer
Advocates believes that the commission is responsible for providing
the oversight on all balancing accounts and that the commission
cannot rely upon Ratepayer Advocates to conduct reviews of
the energy utilities. As we stated in the Introduction, neither the
commission nor Ratepayer Advocates is required to specifically
review balancing accounts.
In contrast, the Division of Water and Audits (water division) told
us that its practice is to perform a detailed review of all balancing
accounts that a water utility includes in its informal filings. The
commission requires a water utility with 10,000 or fewer service
connections to file an informal advice letter to incorporate the
balance in a balancing account into future rates when the balance
exceeds 2 percent of the utility’s total annual gross operating revenue.
Although this requirement was intended to prevent utilities from
filing to recover balancing account balances too frequently, it could
also mitigate the risk that a water utility may not file a timely request
to refund over‑collections from ratepayers. For these smaller water
utilities, the water division indicates it will review balancing accounts
the utility includes in the general rate case. For large water utilities—
those with more than 10,000 service connections—Ratepayer
Advocates will review the general rate case.
The Commission Does Not Have a Systematic Process for Selecting
Balancing Accounts to Review
We believe that the commission’s process for reviewing balancing The commission’s process for
accounts should be based on the risk and the magnitude of the reviewing balancing accounts
potential for unfair rate changes, which would require that should be based on the risk and
the commission maintain an accurate and up‑to‑date list of all the magnitude of the potential for
balancing accounts, including information regarding the balances in unfair rate changes.
those accounts. However, the commission neither maintains such a
list of all balancing accounts nor has it been tracking the authorized
amounts for those accounts in order to assess which accounts may
be candidates for a closer review. When we asked the commission
for a list of all utility balancing accounts it had authorized over
the past nine years, the commission indicated it did not have
that information available but was in the process of compiling
a list in response to a recent Legislative Analyst’s Office report.
20 California State Auditor Report 2013-109
March 2014
According to the commission, it did not have a master list because
balancing account reviews are conducted by staff that have worked
with the utilities and that are most knowledgeable about specific
balancing accounts.
However, in response to our request, the commission asked the
utilities for this information and was able to compile a list of
energy balancing accounts for us during the audit. Going forward,
the commission plans to obtain balancing account information
periodically from utilities and maintain such a database to identify
the balancing accounts of energy utilities it should review. The
water division had already developed a database where it tracked
advice letter filings, including advice letters filed to recover balances
in balancing accounts; but as we discuss below, that database
does not always identify the balancing accounts included in a
water utility’s filing. As a result, the water division also had to
request information from utilities to compile its list of balancing
accounts for us.
Because the commission obtained these lists from the utilities,
we did not perform accuracy and completeness testing on these
data. However, through our limited comparison of these data with
the records of the commission and of Ratepayer Advocates, we
identified concerns about the completeness and accuracy of the
information that the utilities provided and that the commission
compiled, which would limit these lists’ usefulness for guiding the
commission’s future oversight efforts. For example, utilities did not
always identify the authorized amount for a balancing account,
and it was not always clear if this meant that the account had been
closed or if there was a different reason. In certain instances, the
commission noted that there were reasons why a balancing account
would not have an authorized amount. We also discovered several
instances in which Ratepayer Advocates reported reviewing a
specific utility balancing account, but the utility did not include
that balancing account in the information it provided to the
commission for the lists. While the commission compiled these
lists from information that the utilities submitted, it could not
provide assurance that the information was complete and accurate.
Although the lists are a helpful start, if the commission does not
verify the accuracy and completeness of the lists, they will be of
questionable value for future oversight purposes. We present the
information from these lists in Appendix A.
The commission does not have
a complete list of all balancing The commission also does not have a complete list of all balancing
accounts it has reviewed accounts it has reviewed during each year, which may hinder its

recently reviewed. information because its database does not always identify any
California State Auditor Report 2013-109 21
March 2014
balancing accounts the water utility included in the informal filing.
Without knowing when the water division last reviewed a balancing
account, the commission cannot adequately assess the timing of
when to review the balancing accounts of water utilities. The water
division acknowledged this problem and plans to take steps to
record all future reviews.
Analysts Do Not Always Document and Supervisors Do Not Always
Approve Ratepayer Advocates’ Reviews of Balancing Accounts
Ratepayer Advocates does not ensure that its analysts adequately
document and that its supervisors properly approve reviews of
balancing accounts. When utilities file to change future rates based
on balances in a balancing account, Ratepayer Advocates analysts
request and review various documents to determine whether the
commission should grant the requested rate change. Ratepayer
Advocates stated that when the analyst completes a balancing
account review, he or she sends a written testimony, if applicable,
summarizing the findings to a supervisor for approval. The analyst’s
supervisor and program manager review and edit the written
testimony, which includes any findings, the amount of any proposed
reductions in recoveries, or other documents that Ratepayer
Advocates recommends the commission consider during a formal
hearing process. In our examination of 18 reviews that Ratepayer In our examination of 18 reviews of
Advocates analysts conducted, we found that only two reviews balancing accounts that Ratepayer
contained adequate documentation of the procedures that analysts Advocates conducted, only two
completed and the conclusions they reached. Compounding reviews contained adequate

between analysts and their supervisors to ensure that reviews are
properly done. Formal supervisory review would be beneficial to
ensure that Ratepayer Advocates can appropriately support its
conclusions and recommendations to the commission regarding
whether utilities should be allowed to incorporate the amounts in
balancing accounts into their utility rates.
Ratepayer Advocates Does Not Always Properly Document or Retain
Its Reviews
Ratepayer Advocates does not always properly document its
reviews of balancing accounts, and because it lacks a document
retention policy, some documentation of its reviews was not
retained. Because Ratepayer Advocates’ reviews of balancing
accounts can result in recommending that the commission disallow
certain costs that utilities seek to incorporate into future rates,
we expected these reviews to include adequate documentation
22 California State Auditor Report 2013-109
March 2014
evidencing the steps the analysts took to support their conclusions.
However, we found that the extent of supporting documentation
that Ratepayer Advocates’ staff prepared when reviewing balancing
accounts varied considerably among those conducting the reviews.
As shown in Table 5, we examined 18 reviews of balancing accounts
that Ratepayer Advocates conducted in the last three fiscal years
for which Ratepayer Advocates analysts indicated, among other
procedures, that they had verified the accuracy and allowability of
expenditures charged to those accounts, as applicable. We found
that only two reviews had adequate documentation and analyses
to demonstrate the procedures that the analysts performed and
the conclusions that they reached. For example, for one of these
two well‑documented reviews, Ratepayer Advocates reviewed
PG&E’s 2013 ERRA balancing account. Ratepayer Advocates
highlighted each sample it had chosen, and each line item had a
reference letter and number that corresponded to the supporting
documentation, such as invoices.
For 16 reviews of balancing For the 16 remaining reviews, Ratepayer Advocates’ documentation

by the analyst, or was unavailable the analyses included with that documentation were not clear
because it had been discarded. enough or detailed enough to demonstrate the work the analyst
performed. For example, as part of its review of Edison’s Base
Revenue Requirement balancing account, which requested
incorporating a nearly $171 million balance into future rates, the
Ratepayer Advocates’ analyst reviewed utility‑created spreadsheets,
accounting ledger entries, and invoices supporting the amount
in the balancing account. Although we observed that the analyst
made notations on these documents, indicating some level of
review, these notations were not adequate to allow us to verify that
the analyst performed the review steps he identified in his final
written testimony.
For another six of these 16 reviews, Ratepayer Advocates indicated
that the analysts performing the reviews did not create any
documentation during the review to demonstrate the procedures
they followed. For example, in one instance Ratepayer Advocates
was unable to provide documentation of the procedures the analyst
had performed; it reported that because the analyst did not identify
any needed adjustments to the balancing account, the analyst had
created no documentation for the review.

24 California State Auditor Report 2013-109
March 2014
For the remaining three of these 16 reviews, Ratepayer Advocates
indicated that although the analysts had prepared supporting
documentation for the reviews, the documentation was not retained
because it was not needed. Ratepayer Advocates does not have a
document retention policy; after proceedings are completed and the
amount from the balancing account that the utilities will be allowed
to incorporate into rates is finalized, it allows analysts to retain
documents at their discretion if there are no major adjustments or
issues. However, state law requires every state agency, including
Ratepayer Advocates, to have a document retention policy. It is
especially important for Ratepayer Advocates to have such a policy
considering the impact that its reviews can have on utility rates.
Because of the lack of adequate documentation, we could not
analyze Ratepayer Advocates’ recommendations to the commission
that utilities not be allowed to recover all costs in balancing
accounts. For the 18 reviews we examined, Ratepayer Advocates
recommended that the commission reduce by $39 million the
$119 million that utilities requested they be allowed to recover from
four balancing accounts. Ratepayer Advocates did not have adequate
documentation for any of these balancing accounts. For the reviews
relating to two of these four balancing accounts, the commission
rejected Ratepayer Advocates’ protests. Although the commission
did not reject Ratepayers Advocates’ findings and recommendations
for these two reviews on the basis of inadequate documentation,
without proper documentation Ratepayer Advocates lacks assurance
that its reviews are adequate and complete, nor can supervisors
verify the conclusions that staff reach. Moreover, without adequate
documentation, supervisors are unable to determine whether staff
have missed other amounts that utilities should not be allowed
to recover.
Ratepayer Advocates Does Not Ensure That Supervisors Approve
Analysts’ Reviews of Balancing Accounts
Ratepayer Advocates does not have a formal policy requiring
supervisors to document their examination of the analyst’s work that
supports the prepared testimony, even if the analyst recommends
reducing the proposed recovery. Instead, it indicated that supervisory
approval occurs during discussions, meetings, draft testimony review,
and e‑mail discussions with staff about the conclusions reached in
Ratepayer Advocates’ supervisors a review, but supervisors do not examine the actual work analysts
do not examine the actual work perform to ensure that all planned procedures were performed
analysts perform to ensure that appropriately and to ensure that any proposed reductions in recovery
all planned procedures were amounts are accurate. In fact, Ratepayer Advocates was unable
performed appropriately and any to provide evidence of formal supervisory approval for any of the
proposed reductions in recovery 18 balancing account reviews we examined and that are listed in
amounts are accurate. Table 5 on page 23.
California State Auditor Report 2013-109 25
March 2014
Considering that 16 of the 18 reviews we selected lacked adequate
documentation, Ratepayer Advocates cannot be certain that the
reviews that analysts performed were adequate and complete
without documented supervisory approval. A more appropriate
practice, and one that most organizations use when conducting
reviews, is to have supervisors examine and approve the
documentation supporting an analyst’s review to ensure that
the costs that are questioned and other conclusions reached are
accurate, supported, and appropriately documented. In addition
to providing assurance that the analyst’s conclusion to question
some costs is appropriate, such a practice would ensure that the
analyst did not overlook any other unallowable costs. Moreover,
Ratepayer Advocates performs these reviews to fulfill its mission
to obtain the lowest possible rate for reliable and safe service,
which could be undermined by the lack of a supervisory approval
process. Therefore, to best protect ratepayers, Ratepayer Advocates
should be taking steps to ensure that it appropriately performs and
approves reviews of balancing accounts.
Most Water Division’s Reviews of Balancing Accounts Had Supporting
Documentation and Approvals From Supervisors
Most reviews of balancing accounts that the water division
performed had appropriate documentation to show the procedures
that analysts performed and that it had received supervisory
approval. The water division reviews supporting documentation
when water utilities file informally to incorporate the balance from
a balancing account into rates; they also review documentation
for smaller utilities during formal proceedings. As Table 6 on the
following page shows we examined six reviews of balancing accounts
that the water division performed from 2010 through mid‑2013.
Five of these six reviews had adequate documentation to show that
analysts had verified the accuracy and allowability of the charges the
utilities included in the balancing accounts. For these reviews, we
found that the analyst generally verified the balances by analyzing
supporting documentation, such as invoices, as appropriate.
For the remaining balancing account review, which was of
Park Water Company’s filing to recover nearly $2.5 million in
its Water Revenue Adjustment Mechanism balancing account, the
analyst’s documentation was not sufficient for us to determine
the procedures he performed. The water division uses a coversheet
to summarize the analyst’s work and conclusions as well as to
evidence a supervisor’s approval of the work. On the coversheet for
this review, the analyst indicated he checked the support for the
filing and recommended its approval. However, although the review
file contained accounting records and numerous invoices, there
were no notations or marks on these documents to demonstrate
26 California State Auditor Report 2013-109
March 2014
the steps the analyst took to verify the accuracy and allowability of
the costs. The analyst’s supervisor acknowledged that the review
was not properly documented. He stated that the water division
does not have a specific policy requiring analysts to document
their reviews.

Finally, for one of the reviews with adequate documentation, a
supervisor did not sign off on the analyst’s review. The director
of the water division indicated that the water division requires
supervisory approval of all reviews and that the lack of supervisory
sign‑off on this review was an oversight.
The Commission Does Not Comply With Certain Auditing and
Reporting Requirements of State Law
The commission also does not inspect and audit the records of
utilities it regulates according to the schedule prescribed by law, nor
does it provide the reports of these audits to the California State
Board of Equalization (Equalization). Specifically, state law requires
that the commission audit the accounting records of a utility
every three or five years, depending on the number of customers
the utility serves. The commission generally fulfills this audit
requirement using the procedures it conducts in connection with a
California State Auditor Report 2013-109 27
March 2014
general rate case, as the law allows. However, the commission does
not ensure that utilities file general rate cases every three or five
years to coincide with the audit requirement. As a result, it has not
always complied with the legal requirement to periodically audit
the utilities according to the prescribed schedule. This law also
requires the commission to provide the reports of these audits to
Equalization for use in assessing taxes on public utilities. However,
the commission discontinued providing the required reports
to Equalization shortly after the law became effective in 1975
because Equalization notified the commission that the audit reports
were not useful for tax assessment purposes. Equalization believes
that requiring the commission to perform the audit work for tax
assessment purposes would not be cost‑beneficial for the State
because Equalization already possesses this expertise.
The Commission Does Not Always Audit Periodically the Books and Records
of the Utilities It Regulates According to the Schedule Prescribed by Law
The commission does not always conduct periodic audits of the
books and records of the utilities it regulates according to the
schedule prescribed by state law. Specifically, state law requires
that every three years the commission audit the accounting records
of utilities that serve more than 1,000 customers. The law also
requires the commission to audit every five years those utilities that
it regulates that have 1,000 or fewer customers. As state law allows,
the commission fulfills this audit requirement using the procedures
conducted in connection with a general rate case. During that
proceeding, the commission’s staff, Ratepayer Advocates, and
advocacy groups review the various costs and other financial
information that the utility presents to support its proposed rates.
The commission facilitates and, if needed, compels the utility to
provide additional information that the parties request to evaluate
the reasonableness of its request for cost recovery.
However, the commission does not ensure that all regulated The commission does not ensure

a general rate case every three years, it has allowed two energy cycle to allow it to meet the law’s
utilities to file rate cases on a four‑year cycle and it does not audit requirement.
require three other smaller energy utilities to be on a three‑year
cycle. Because each of these five energy utilities serve more than
1,000 customers, having them file beyond the three‑year cycle
does not allow the commission to fulfill the state law’s requirement
that they be audited every three years. The commission also allows
one energy utility with fewer than 1,000 customers to adjust its
rates solely using informal proceedings without periodically filing a
general rate case. The director for the energy division acknowledged
28 California State Auditor Report 2013-109
March 2014
that the commission was not in compliance with the law but
indicated that these utilities might file a general rate case every
three years in the future.
In addition to the six energy utilities that it has not required to file
general rates cases every three or five years, the commission also
does not require all water utilities to file their general rate cases on
a regular schedule. Of the 116 water utilities that the commission
regulates, 26 have more than 1,000 customers, requiring that they
be audited every three years. The remaining 90 have 1,000 or fewer
customers, requiring the commission to audit them every five years.
However, the commission only requires the 10 largest water utilities
to file a general rate case every three years. The director of the water
division reported that the commission does not require smaller water
utilities to file their general rate cases under any specific schedule.
When we reviewed the dates that water utilities had filed their last
two general rate cases, we found six of the 26 largest utilities subject
to the three‑year audit requirement and 53 of the 90 smaller water
utilities subject to the five‑year audit requirement did not always
meet their respective timelines. One of these smaller utilities had not
filed a general rate case since 1993, and another filed its most recent
general rate case more than 20 years after its previous one.
Because the commission relies upon the general rate case to comply
with the audit requirement, to the extent that water utilities do not
file their general rate cases every three or five years, the commission
is not in compliance with state law. The director of the water division
indicated that because of the complexity involved in establishing
utility rates, many smaller water utilities require the water division’s
assistance to file their general rate cases and resource constraints
limit the water division’s ability to assist them. Further, he asserted
that the water division lacks the resources to audit all water utilities
that do not file their general rate cases within the statutory timeline.
Moreover, the commission noted that when the smaller water
utilities establish their rates, it performs a thorough review of the
utility’s expenses and plant to determine that the approved rates are
reasonable. The commission noted that utilities file for a general rate
case to request authority to increase their revenues from ratepayers.
Therefore, it was the commission’s belief that to the degree that
these smaller water utilities are not filing for general rate cases, their
customers benefit from stable rates.

that it is adequately protecting the history of the state law requiring the commission to regularly
ratepayers from high utility rates. audit these utilities indicates that the Legislature intended that
these audits would be safeguards for the public and would protect
against excessive rates. To the extent that the commission does not
California State Auditor Report 2013-109 29
March 2014
ensure that it audits all regulated utilities as required, it does not
meet the intent of the law to maintain public confidence in the
regulatory process.
Equalization Believes a State Law Requiring Coordination of Audits With
the Commission Is Out of Date
Equalization believes that a provision of state law requiring
the commission to provide audit reports to Equalization is no
longer appropriate. The law that requires the commission to
audit periodically the records of utilities also requires that the
commission provide the audit reports to Equalization for use
in assessing taxes on public utilities. As noted in the previous
section, the commission has chosen to meet the audit requirement
through general rate cases, which results in written testimonies that
summarize the results of the reviews of a utility’s costs; staff present
these testimonies to the commission during a hearing.
Because general rate cases are regulatory proceedings that examine Because the commission’s
a utility’s operations and costs and are concerned with the rates general rate cases are regulatory
that the utility may charge its customers, these proceedings do proceedings, these proceedings do
not focus on the utility’s accounting records for taxation purposes not focus on the utility’s accounting
and they are thus of no use to Equalization. For example, although records for taxation purposes and
Equalization assesses taxes on the cost of construction work that are thus of no use to Equalization.
is not yet completed, the commission does not allow a utility
to consider this type of cost when developing rates until the
construction is completed and the property is put into service.
Additionally, Equalization has taxing authority only over those
taxable properties that are within California, while some utilities
have assets outside of California that nevertheless can influence the
commission’s rate setting. For example, an electric utility might own
a power plant in another state to generate electricity to provide to
California ratepayers. The commission allows the utility to recoup
through its rates some or all of the cost of building the out‑of‑state
power plant. However, because the plant is in another state,
Equalization does not have the authority to assess taxes on it.
According to Equalization, in addition to the lack of tax‑related
information within the commission’s reports, the timing of the
general rate case for a utility is often not when Equalization needs
the information for tax purposes. For example, the commission
usually requires an electric utility to file a general rate case every
three years. However, Equalization must complete audits on utilities
within a four‑year period, which may not align with the general
rate cases. Equalization indicated the property tax audits that its
staff perform focus on the taxable or nontaxable nature of property
costs at a level of detail that is not available from the commission’s
reports. It further noted that it has maintained an audit program
30 California State Auditor Report 2013-109
March 2014
since 1977 and therefore has not required the commission’s reports.
As a result, despite the legal requirement to do so, the commission
has not provided these required reports to Equalization in more than
three decades.
Equalization indicated that because it needs to assess taxes on a
variety of companies that may not be regulated by the commission,
it has a process in place to audit these companies as necessary.
According to Equalization, it does not have auditors specifically
dedicated to auditing utilities that the commission regulates so
it cannot quantify the cost of auditing those utilities; however,
Equalization asserted that the additional cost it incurs for auditing
the utilities the commission regulates is insignificant. Moreover,
Equalization noted that it has been performing the tax assessment
audits of utilities for many years and its staff possess the specific
qualifications required of tax auditors. Equalization believes that
the cost for the commission to begin performing this work would
outweigh any benefits or cost‑savings Equalization might realize.
Although Equalization’s conclusion appears reasonable, unless the
statute is amended to remove this duty to provide the audits,
the commission will continue to be out of compliance with the
law. The director of the energy division indicated that in order for
the commission to take a position on changes to existing law, it is
required to vote on the matter. Therefore, commission staff cannot
provide an official position on any changes to this law.
Recommendations
To ensure proper oversight of balancing accounts to protect
ratepayers from unfair rate increases, the Legislature should amend
the California Public Utilities Code, Section 792.5, to require the
commission to develop a risk‑based approach for reviewing all
balancing accounts periodically to ensure that the transactions
recorded in the balancing accounts are for allowable purposes and
are supported by appropriate documentation, such as invoices.
To ensure that it has the necessary information to provide
appropriate oversight of the balancing accounts, the commission
should maintain accurate and timely information on utility
balancing accounts. Specifically, it should do the following:
• Review the accuracy and completeness of the data it has
obtained from utilities to ensure that it has a complete list of
balancing accounts.
California State Auditor Report 2013-109 31
March 2014
• Regularly update this list of balancing accounts when the
commission issues decisions authorizing opening new balancing
accounts or closing existing balancing accounts, when utilities
file balancing account updates, and when the commission
performs reviews of balancing accounts.
• Use this list to guide its efforts to oversee balancing accounts
more effectively, by using a risk‑based approach to select a
sufficient number of balancing accounts, as well as those with
the most potential impact on ratepayers, for review each year to
provide appropriate coverage over all regulated utilities.
To ensure that it efficiently and effectively monitors energy utilities’
balancing accounts to protect ratepayers from unfair rate increases,
the commission should do the following:
• Direct the energy division to perform in‑depth reviews of
balancing accounts to verify that account balances contain only
allowable transactions and are supported. These reviews should
include ensuring that transactions recorded in a balancing
account are supported by appropriate documentation, such
as invoices.
• Direct the energy division to coordinate with Ratepayer Advocates
to identify which balancing accounts Ratepayer Advocates plans to
review during the year to avoid duplicating efforts.
To further its mission to obtain the lowest possible rates for
reliable and safe utility service for ratepayers through its reviews of
balancing accounts, Ratepayer Advocates should do the following:
• Use the commission’s list of balancing accounts to guide its selection
of the number, size, and type of balancing accounts to review so that
its review coverage is more proportional across all utilities.
• Document the method used for its selection of balancing
accounts to review.
• Coordinate with the energy division to avoid duplicating
review efforts.
To ensure that findings and conclusions resulting from the reviews
of balancing accounts are appropriate, complete, and supported,
Ratepayer Advocates should perform the following, within six months:
• Develop policies that clearly describe how analysts are to
document their reviews of balancing accounts, including all work
reviewed and conclusions reached for each sampled item that
supports their conclusions.
32 California State Auditor Report 2013-109
March 2014
• Develop a document retention policy for all documents related
to, among other things, balancing account reviews for a
minimum of three years after the completion of these reviews.
• Implement a formalized and documented method to ensure
that supervisors approve analysts’ reviews of balancing accounts
by checking the accuracy and completeness of the work that
analysts prepare to support the conclusions of their reviews,
including any proposed reductions in recoveries.
To ensure that findings and conclusions resulting from the reviews
of balancing accounts are appropriate, complete, and supported, the
water division should remind analysts to document their reviews
properly and remind supervisors to formally indicate that they
checked the accuracy and completeness of reviews.
The commission should follow the requirement in state law to
inspect and audit the accounting records of utilities it regulates
within required time frames. If the commission chooses to continue
to meet this requirement through the general rate case process, it
should ensure that all utilities file a general rate case on a regular
schedule so as to comply with the state law’s audit requirement.
However, the commission should follow alternate methods to
comply with the audit requirement when a utility will not be
filing for its general rate case in time to be audited within three or
five years, depending on the timing of the required audit for
that utility.
The Legislature should amend California Public Utilities Code,
Section 314.5, to remove the requirement that the commission
provide audit reports to Equalization.

Appendix A
PUBLIC UTILITY BALANCING ACCOUNTS ACTIVE DURING
THE LAST NINE YEARS AND THE FREQUENCY OF THEIR
DETAILED REVIEW
State law requires the California Public Utilities Commission
(commission) to direct utilities to track specific types of costs and
related revenues from customers using a tracking mechanism. This
tracking mechanism—known as a balancing account—protects
ratepayers and utilities by identifying any under‑ or over‑collection
of revenue from ratepayers compared to the utilities’ actual allowed
costs. Utilities establish and maintain the balancing accounts
after the commission authorizes those accounts. However, the
commission does not maintain a central database of all balancing
accounts and related revenue requirements it has authorized for a
utility. Upon our request, the commission obtained the information
from the utilities it regulates related to balancing accounts
established over the past nine years—2004 through 2012—and
provided that information to us. However, as we stated in the Audit
Results, we did not audit this information to verify its accuracy
and completeness. As such, the information the commission
provided us is of undetermined reliability. However, through our
limited comparison of these data with the commission’s and the
Office of Ratepayer Advocates’ (Ratepayer Advocates) records, we
noted some concerns with the data that the utilities reported to
the commission. For instance, we found several instances in which
a utility did not include at least one balancing account. However,
it is the only source of information available and we present it in
Table A on the following pages.
We also obtained information from Ratepayer Advocates and the
Division of Water and Audits (water division) to determine which
balancing accounts they reviewed during the nine‑year period
from 2004 through 2012. We performed limited tests to verify
the accuracy of the information Ratepayer Advocates provided by
reviewing the appropriate documents or reports to ensure that the
selected balancing accounts were reviewed as noted. On the other
hand, as indicated in the Audit Results, the water division cannot
identify a comprehensive list of balancing accounts it has reviewed
without devoting significant resources. Therefore, we could not
include the reviews that the water division performed of water
utility balancing accounts. However, the water division was able to
identify certain balancing accounts it reviewed as part of two audits
it performed at the direction of the commission. Table A shows the
number of accounts active during the nine‑year period from 2004
through 2012 and whether the commission reviewed them.

Sources: Data that the California Public Utilities Commission (commission) obtained from utilities and the Office of Ratepayer Advocates (Ratepayer
Advocates). Most reviews were performed by Ratepayer Advocates, and a few were performed by the Division of Water and Audits (water division). The
commission did not provide balancing account information for three small natural gas utilities because it indicated that their balancing account activity
was minimal. The commission also did not provide us balancing account information for 100 small water utilities that have fewer than 2,000 service
connections because it believed obtaining this information from the small utilities would have been overly burdensome on those utilities. Further, the
commission informed us that two larger water utilities did not have any balancing accounts during the nine‑year period.
Notes: As we state in the Scope and Methodology, we did not audit these data to verify their accuracy and completeness. Therefore, these data are of
undetermined reliability. However, in our limited comparison of these data with the commission’s and Ratepayer Advocates’ records, we noted some
concerns with the data. However, we present this information because it is the only source of data available.
Based on the commission’s direction, we shaded balancing accounts tan where the utility did not report any activity in a given year. However, we
cannot confirm in each instance if the account was open but inactive, or if it was closed during that time period. In addition, we found some instances
where the commission mistakenly indicated that the balancing account was inactive in a year where the utility had recorded activity, or in a year where
Ratepayer Advocates indicated a review had occurred.
= Reviewed by Ratepayer Advocates or the water division.
* The utilities did not always identify authorized amounts for all balancing accounts. Although the commission noted that certain accounts do not
have annual revenue requirements, and some omissions may have been for accounts that had been closed or were inactive, the commission could
not verify the reasons for all accounts for which authorized amounts were not included.
† This review covered less than six months of activity.
‡ The utilities did not include these balancing accounts in the data they provided to the commission. However, these accounts were listed in reviews
the Ratepayer Advocates performed.

Appendix B
OUR REVIEW OF BALANCING ACCOUNTS MAINTAINED
BY UTILITIES THAT ARE REGULATED BY THE CALIFORNIA
PUBLIC UTILITIES COMMISSION
To determine the expenditures the utilities included in selected
balancing accounts, we selected and reviewed nine balancing
accounts maintained by six utilities that the California Public
Utilities Commission (commission) had not reviewed during fiscal
years 2010–11 to 2012–13. We chose three balancing accounts
related to water utilities, three related to natural gas utilities, and
three related to electric utilities. Our selection included larger
utilities such as Pacific Gas and Electric Company with over 5.1
million electric customers and 4.3 million natural gas customers
as well as utilities such as Suburban Water Systems, which has
300,000 customers. To ensure that we reviewed a cross‑section of
activities, we selected balancing accounts of differing purposes and
of different sizes based on the balances. Table B on the following
page shows the results of our review of the nine balancing accounts
that the commission had not reviewed. Based on our testing of
balancing accounts at these six utilities, we concluded that the
balancing accounts were properly maintained and we found no
exceptions.

CALIFORNIA STATE AUDITOR’S COMMENTS ON
THE RESPONSE FROM THE CALIFORNIA PUBLIC
UTILITIES COMMISSION
To provide clarity and perspective, we are commenting on the
California Public Utilities’ Commission’s (commission) response to
our audit. The numbers below correspond to the numbers we have
placed in the margin of the commission’s response.
The commission misstates the scope of our audit. Specifically, the 1
purpose of our audit was not “to review the [commission’s] audit
practices overall.” As we state in the Scope and Methodology on
page 12, the scope of the Joint Legislative Audit Committee’s audit
request was limited to the commission’s oversight of balancing
accounts. Table 2 beginning on page 12 lists the objectives of our
audit, all of which relate to balancing accounts.
The commission’s statement implies that we evaluated the 2
appropriateness of the audits it performs in conjunction with
general rate case proceedings. To clarify, as we describe on
pages 27 to 29, our scope was limited to determining whether the
commission met the requirement in Section 314.5 of the California
Public Utilities Code to audit the accounting records of a utility
every three or five years, depending on the number of customers
the utility serves. We did not evaluate the appropriateness of the
audit procedures that the commission performs in conjunction with
a general rate case proceeding.
We disagree with the commission’s statement that it “does not have 3
a business need for a master list of all of the balancing accounts.”
To implement our recommendation on page 31 to develop a
risk‑based approach for selecting balancing accounts for review,
the commission will also need to implement our recommendation
to maintain accurate and timely information on utility balancing
accounts. Without such a list, the commission will lack information
on the overall population of balancing accounts to make informed
decisions about which accounts may be candidates for a closer
review. Moreover, despite its assertion of not needing this master
list, the commission acknowledges later in the response that it will
update and verify the list developed in response to our request
during the audit.

CALIFORNIA STATE AUDITOR’S COMMENTS ON THE
RESPONSE FROM THE OFFICE OF RATEPAYER ADVOCATES
OF THE CALIFORNIA PUBLIC UTILITIES COMMISSION
To provide clarity and perspective, we are commenting on the
response to our audit report from the Office of Ratepayer Advocates
(Ratepayer Advocates) of the California Public Utilities Commission
(commission). The numbers below correspond with the numbers
we have placed in the margin of Ratepayer Advocates’ response.
As part of our quality control process, our standard practice is to 1
provide agencies five working days—the agency review period—
to review and comment on a draft copy of the report. During
this time, we encourage agencies to discuss with us any concerns
with the report, including any factual issues or word choices they
may identify. In keeping with this practice, we provided copies of
the draft report for Ratepayer Advocates staff to read at the exit
conference on January 23, 2014. Further, during the agency review
period, we contacted Ratepayer Advocates’ acting director or senior
manager on three occasions and offered to discuss any concerns
that the Ratepayer Advocates may have had; yet, Ratepayer
Advocates did not accept our offers. In contrast, we had several
conversations with the commission during the agency review
period and, as appropriate, incorporated the commission’s feedback
into our final report.
We are aware that utilities may request recovery of certain costs 2
in proceedings other than the general rate case proceeding
(general rate case). However, we focused on the general rate case
proceedings because the commission indicated that the majority of
utility costs are examined and most of the balancing accounts are
authorized during general rate case proceedings.
This is an issue that we would have expected Ratepayer Advocates 3
to let us know about during the agency review period. To address
Ratepayers Advocates’ concern that our statement was too broad,
we added the phrase “for certain activities” to the sentence on
page 1.
This is an issue that we would have expected Ratepayer Advocates 4
to let us know about during the agency review period. Based on
discussions with the commission during the agency review period,
we had already revised the text on page 1 to reflect the change that
Ratepayer Advocates is suggesting.

Ratepayer Advocates misunderstands the purpose of our Report
Summary, which provides a high‑level overview of the key issues
in our report, but is not intended to restate every issue. In this
instance, we are discussing our concern with the commission’s
reliance on Ratepayer Advocates for the review of balancing
accounts of energy utilities. Later, in the Introduction, we discuss
Ratepayer Advocates’ oversight of balancing accounts of water
utilities in Table 1 on page 11 and in the text on page 10.
6
Ratepayer Advocates misses the point of our concerns with its
practices for reviewing balancing accounts. As we show in Table 3
on page 17, Ratepayer Advocates’ level of review varied considerably
among the six largest energy utilities. Specifically, although it
reviewed 94 percent of the value of Southern California Edison’s
(Edison) balancing accounts, it reviewed a substantially lower
percentage of the value of the balancing accounts for the other
five large energy utilities—between 27 percent and 79 percent.
Further, as we show in Table 4 on page 18, the value of the
three largest balancing accounts that Ratepayer Advocates did not
review for the six large energy utilities totaled more than $25 billion,
which could have a significant impact on the future rates that
utilities charge ratepayers.
7
Throughout its response, Ratepayer Advocates refers to the
procedures it performs on balancing accounts as “audits.” However,
as noted in the footnote at the bottom of Table 2 beginning on page
12 of our report, we refer to these procedures as “reviews” because
the procedures it performs do not constitute a complete audit
under audit standards.
8
Ratepayer Advocates misinterprets our finding. While Ratepayer
Advocates analysts’ written testimonies may undergo reviews
by supervisors and management, as we state on page 24, its
supervisors do not examine the work supporting these testimonies
to ensure analysts perform all planned procedures appropriately
and that any proposed reductions in recovery amounts are accurate.
In fact, we found no evidence of documented supervisory approval
of the analysts’ work for any of the 18 reviews we tested. Moreover,
as discussed on page 22 and as shown in Table 5 on page 23,
16 of these 18 reviews of balancing accounts lacked adequate
documentation to demonstrate the work that Ratepayer Advocates’
analysts performed, was not created by an analyst, or was not
available for our review because it had been discarded.
9
Ratepayer Advocates’ statement is erroneous as our report
does not include a finding of “no errors in 9 years of [Ratepayer
Advocates] audits.” To the contrary, we noted a pervasive lack
of documentation and supervisory approval for the 18 reviews
that we tested, as shown in Table 5 on page 23 and discussed
California State Auditor Report 2013-109 69
March 2014
on pages 21 through 25. Moreover, as Table 2 beginning on
page 12 indicates, we limited our testing of these reviews to fiscal
years 2010–11 through 2012–13.
Contrary to Ratepayer Advocates’ assertion of using a “risk 10
based approach,” it was unable to provide us with any evidence
of this approach—such as a written policy or methodology, or
contemporaneous documentation of its reasons for determining
which balancing accounts are most significant to its mission. In
fact, a senior manager within Ratepayer Advocates confirmed for
us that no written policy existed and that Ratepayer Advocates
produces no documentation from the periodic meetings it holds
to discuss the selection of balancing accounts to review. Lacking
this documentation, we are unable to evaluate or verify Ratepayer
Advocates’ claims of employing a risk‑based approach to determine
the accounts or areas of accounts on which to focus its efforts.
We are aware that California Public Utilities Code, Section 792.5, 11
as it currently reads, requires balancing accounts to be established
to track pass‑through costs. However, the commission also
authorizes utilities to establish balancing accounts to track other
costs and, as we state on pages 10 and 15 of the report, other than a
requirement to semiannually review the Energy Resource Recovery
Accounts, there is no specific requirement related to reviewing
balancing accounts of any other type. Therefore, we stand by our
recommendation that the Legislature amend this section to require
the commission to develop a risk‑based approach to reviewing
balancing accounts. Nevertheless, we added the word “all” to our
recommendations on pages 3 and 30 to clarify that the risk‑based
approach should be used to review all balancing accounts.
This is an issue that we would have expected Ratepayer Advocates 12
to let us know about during the agency review period. To clarify the
nature of interveners, we added “businesses” and “special interests”
to the description on page 7.
This is an issue that we would have expected Ratepayer Advocates 13
to let us know about during the agency review period. To clarify
that not all costs within each cost component are tracked in a
balancing account we added the text “certain activities” in the top
section of Figure 2 on page 7. In preparing Figure 2, we worked
with the commission during the audit to ensure that it accurately
reflected all information. However, after reviewing Ratepayer
Advocates’ response, we again reached out to the commission
to ensure the figure’s accuracy. Upon further discussion, the
commission agreed with Ratepayer Advocates’ assertion that
capital costs are not tracked using balancing accounts. We revised
the figure to reflect that fact. However, based on discussions with
70 California State Auditor Report 2013-109
March 2014
the commission, other than these two changes, we believe that the
remainder of the information in Figure 2 is accurate, thus we did
not make the other changes that Ratepayer Advocates suggests.
14
This is an issue that we would have expected Ratepayer Advocates
to let us know about during the agency review period. Based on our
discussions with the commission during the agency review period,
we had already revised the text on page 8 to clarify that utilities
recoup or refund the difference between the interim and final
rate from ratepayers after the commission has authorized the
final rate.
15
Ratepayer Advocates misunderstands our finding. We do not cite
generally accepted accounting principles as a reason to properly
document and have supervisors approve balancing account reviews.
Rather, as we state on page 25, considering that 16 of the 18 reviews
we selected lacked adequate documentation, Ratepayer Advocates
cannot be certain that the reviews that analysts performed were
adequate and complete.
16
We commend Ratepayer Advocates for beginning the process to
establish a standardized log to document supervisory approval of
analysts’ reviews. However, as part of its supervisors’ approval,
Ratepayer Advocates will also need to ensure that analysts
actually prepare appropriate documentation of their reviews.
Moreover, although Ratepayer Advocates asserts that “all
[Ratepayer Advocates] reviews must be approved by [a] supervisor,”
as we note on page 24, none of the 18 reviews we tested had
evidence of a supervisory approval.
17
Ratepayer Advocates confuses its final product—the written
testimony—with documentation of the procedures that analysts
complete when performing a balancing account review. While
Ratepayer Advocates provided us with the testimonies related
to the 18 balancing account reviews we tested, including the
three balancing accounts it specifically mentions, it was unable to
provide us with the analysts’ original work used in compiling those
testimonies. In fact, on December 17, 2013, a Ratepayer Advocates
senior manager confirmed in writing to us that analysts created no
documentation for the three reviews. Further, in response to our
request for this documentation, because it allows staff to keep their
workpapers at their discretion, Ratepayer Advocates generally told
us to directly contact analysts who performed the 18 reviews.
