How many GWh of battery storage have California grid operators built recently?

[Gibbon1]

Moss Landing can deliver 750MW with 3.0 GWh of total capacity. State has a total of 5GW. 90% of it rolled out in the last 3 years.

The problem with building a nuke plant starting today is it'll be a stranded asset before it goes online in 10-15 years.

So 5GWh of storage capacity would be about 0.6% of average daily usage. We're going to need a lot more than that to make renewables viable for base load. How much will that cost, how long will it take to build, and where will we mine the raw materials?

Well ten years ago you would have said the idea that solar and wind would be 25% of the states power generation in ten years was total nonsense.

But here we are.

Three years ago, well yesterday, you would have said the idea that the state would have 5 GW of utility batteries was nonsense.

But here we are.
