. . . This bill—known as The 100 Percent Clean Energy Act of 2018—increases the Renewables Portfolio Standard (RPS) requirement from 50% by 2030 to 60% and creates the policy of planning to meet all of the state’s retail electricity supply with a mix of RPS-eligible and zero-carbon resources by 31 December 2045, for a total of 100% clean energy.
Specifically, the bill accelerates the RPS obligations for retail sellers—investor-owned utilities, community choice aggregators, energy service providers—and publicly-owned utilities (POUs) as follows:
40% to 44% by 2024;
45% to 52% by 2027; and
50% to 60% by 2030.
The bill also establishes state policy that RPS-eligible and zero-carbon resources supply 100% of all retail sales of electricity to California end-use customers no later than 31 December 2045.
The bill stipulates that achieving this policy shall not increase carbon emissions elsewhere in the western grid and shall not allow resource shuffling subject to the restrictions of the Commerce Clause of the United States Constitution.
The bill requires the California Public Utilities Commission (CPUC), the California Energy Commission (CEC), the California Air Resources Board (CARB), and other state agencies to incorporate this policy into all relevant planning. . . .
As of 2017, California got 29% of its electricity from renewables, plus another 15% from large hydro and 9% from nuclear (Diablo Canyon, due to close in 2014-25). NG is 34%.
