Part of the problem is the source data. In one example the article mentions a battery is 680MW and has 4 hours of discharge. But most of the source data is a LBNL Interconnection Queue report that does not have that data available (the Council of Economic Advisors seems to be using this). I know the source report does not have this data because it is not published in the report and the lab does not have it (I’ve asked them).

Well, I've eyeballed the capacity of the storage in the system from the graph at around 25 to 30GWh. The CAISO website does allow downloading per-day CSV files of the 5-minute power on a per-day basis. There is also the question of behind-the-meter batteries which presumably do not show up (neither generated solar nor evening peak consumption saved).
