> they now have 5.5GW of battery backup capacity that covers the critical period at dusk, when solar generation is headed for zero, during late summer where the days are getting shorter but it is still hot
Am I supposed to interpret "covers critical period at dusk..." as the "hours" part of 5.5GW? Because I'm having trouble grokking what is the actual battery backup capacity described here... Does CA have battery capacity that can last a single evening @ 5.5GW of load?
Every grid-scale battery in CA has 4 hours of energy capacity at its rated power, so 22GW-h at present.
Thank you!
