California’s green energy fleet is to undergo a deep-reaching transformation in the space of a decade under new targets, adopted by the US state’s regulator just this week.
Solar and energy storage batteries will be the two cornerstone technologies of a plan to add nearly 25GW in new renewable capacity to the Golden State by 2030, in a bid to push greenhouse gas emissions down to 46 million metric tonnes (MMT) by the same year.
The roadmap approved by the California Public Utilities Commission (CPUC) will see 11GW of new utility-scale solar installed by 2030, leading to a cumulative 25.9GW. For their part, storage battery systems must add a fresh 8.87GW to reach a cumulative 12GW by the same year.
The achievement of CPUC’s 25GW target – effectively more than doubling California’s current installed green energy capacity – will rest on power providers, including investor-owned utilities such as the Pacific Gas and Electric Company (PG&E), community choice aggregators and others.
These firms must draw up plans on how they will contribute their share of the zero-carbon push. Once it reviews providers’ submissions, the CPUC will decide whether California will work towards a green energy portfolio able to deliver the 46 MMT target, or an even stricter 38 MMT goal.
