The California Public Utilities Commission (CPUC) has authorised a new centralised strategy for procuring long-lead-time resources, including long-duration energy storage (LDES).
The CPUC has proposed the procurement of over 10GW of new energy resources, including 1GW of multi-day long-duration energy storage (LDES) and another 1GW of 12-hour-plus LDES.
A ‘first of its kind’ microgrid will be installed at a California substation, where it will use a combination of lithium-ion batteries and green hydrogen to provide 48 hours of back up.
NextEra’s eight-hour energy storage project in California will use lithium-ion technology, but ‘battery chemistry did not play a major role in project evaluation’, offtaker Clean Power Alliance told Energy-Storage.news.
