CALIFORNIA STATE AUDITOR Report 2023-127 | March 2025 Table A.1 Utilities’ Efficiency Program Portfolio Electric Energy Savings From 2012 Through 2022 Gross GWh Net GWh Utility 2012 2013 2014 2015 2016* 2017 2018 2019 2020 2021 2022 PG&E 915 752 748 690 671 642 400 394 253 288 331 SCE 1,178 642 936 804 722 554 333 289 165 147 192 SoCalGas 13 3 12 13 9 8 7 5 1 5 3 SDG&E 262 164 165 159 201 165 114 75 73 61 51 Totals 2,367 1,561 1,860 1,666 1,603 1,369 853 762 492 501 577 Source: CPUC data. Note: Totals may differ slightly due to rounding. Electric energy savings are expressed in terms of saving gigawatt hours (GWh) of electricity. One GWh of electricity is equal to the average annual electricity consumption of 162 households. During our audit period, from 2012 through 2017, the CPUC measured energy savings on a gross basis. This means measuring the amount of energy savings without considering the reasons for participation in the efficiency program. From 2018 through 2022, the CPUC shifted to measuring energy savings on a net basis. This means measuring the amount of energy savings directly caused by the efficiency program. * The 2016 efficiency program data represent utilities’ claimed energy savings without independent verification. For the remaining years, the CPUC had an independent consulting firm evaluate utilities’ claimed energy savings for accuracy but did not verify 100 percent of the data.
