The California Public Utilities Commission should reject calls to delay adding new power supplies in the state even though the Diablo Canyon nuclear power plant’s impending retirement may be put on hold, according to the California Independent System Operator.

CAISO also supports a recommendation from the CPUC’s Public Advocates Office that the commission authorize immediate procurements to address system needs from 2026 through 2030, the grid operator said in comments it filed at the commission on Thursday.
