So still have a huge market of the Solar energy
PS:I should work harder

That’s even more impressive when you consider that California would be in the G7 if it were a country.

Anyone know about their battery storage capacity?

I wonder how much private residential the state has, an unknowable figure I think?

Something I noticed about the huge amount of battery storage that Cali has already (and continues) deployed, is that the power figure is behind but chasing the mid day peak reduction in grid demand - the 'duck curve'. So for instance, when the mid day reduction was down 8GW, there seemed to be around 5GW of storage, most of it 2-4hrs.

Obviously I'm reading quite a lot into this, but it suggests that much of the daytime excess can be stored, and is then available for the higher grid demand in the late afternoon/evening as PV gen falls. I think Cali will need around 15GW of storage to cope really.

Quite incredible how well things are lining up for sunny climes, with falling costs and rising deployments of PV and storage. And the ability to cycle the batts most days throughout the year, to improve the economics.

One of those articles says they currently have about 7GW but ill need 50GW by 2045, unfortunately they don't mention the energy storage capacity only the power, but based on our usual view of journalists this coud GWh rather than GW.

This will almost certainly be GW, not GWh. I think the UK is aiming for around 20GW by 2030.

Typically, energy storage on the grid scale/side is discussed in terms of power, not energy, as it's about meeting demand at any point in time. Also, the storage being deployed will vary depending on it's role, so some may be close to 1hr, with much in the 2-4hr range. Not sure if Cali is yet looking at much LDES (long duration energy storage), but they are deploying some CAES and LAES (compressed air or liquid air energy storage), which is more likely to be in the 4-10hr range.

I think any tech, including batteries, can be long duration. It's just that the economics are much poorer due to much lower cycling frequencies, so we won't tend to see it until rapid cycling storage needs are satisfied.
