California has been receiving a lot of positive attention in the media and elsewhere for the large amount of lithium-ion battery storage capacity that has been added to the electrical grid since last summer.
The heightened focus makes sense. No electrical grid in the country, if not the world, has integrated more battery storage onto its power system than the ISO over the past year. Last summer, for example, there was about 250 megawatts (MW) of battery storage on the CAISO grid. Currently, there is about 2500 MW and greater amounts of battery power will continue coming online in the months and years ahead. In fact, the California Public Utilities Commission’s draft preferred system plan calls for 12,000 MW of installed utility scale batteries by 2025.
So far, the additional capacity, despite a few supply chain and operational glitches that are to be expected with something so vast and so new, has been performing very well.
The rest of the country will follow California’s lead in this area.
