The California grid operator has a really cool website that shows realtime-ish graphs of supply and demand[1] and even daily battery reports[2]. One big takeaway is that the total battery capacity is kinda wimpy when you compare it to how much fossil fuel the state burns over the day. The way net metering worked in the past is that people with solar could offload their access generation to power companies and make storage or resale the utility's responsibility. Then 2.0 was a sorta-time of use implementation, and now we're up to Net Metering 3.0 and I haven't bothered to look into how that works. However people I know who have looked into Tesla powerwalls haven't found them to be economical for individual homeowners.
