this is the actual quote from the new york times
Those batteries play a pivotal role in California’s electric grid, partially replacing fossil fuels in the evening. Between 7 p.m. and 10 p.m. on April 30, for example, batteries supplied more than one-fifth of California’s electricity and, for a few minutes, pumped out 7,046 megawatts of electricity, akin to the output from seven large nuclear reactors.

Surely all California needs is to multiply the number of batteries right?

1."California's batteries took over gas as the primary source" so lets say conservatively gas was 50% - 2 x the current battery count (CBC)
2. "and, for a few minutes, pumped out 7,046 megawatts of electricity" so lets say conservatively few = 4 - That's 24hr*60min/hr / 4 = 360CBC. 2 x 360 = 720 CBC
3. They will need to charge batteries while others are discharging - so that's 2 x 720 = 1440 CBC
4. Now the allowance for wind and solar output. Assume California capacity factor 0.15 and wind 0.25 - average 0.2. That's 1440 * 5 = 7,200 CBC
5. Now how many days is it possible that there is no wind or sun? Assume it could be as short as a week. Say 7 x 7,200 = 50,400.

So as we can see - California only needs to expand its battery provision by a factor of 50,000, and hope for no more than 1 week of energy capture from sun and wind.

What's the problem?
