"We analyzed 5 recent large-scale power failures in the US, including the rolling blackouts caused by Winter Storm Uri in 2021. We found that gas plants accounted for most of the failed capacity in all 5 events."

The "reliability" of fossil gas is a myth.https://t.co/nmzXO0ze1F
See my post on new questions about gas generator’s reliability here.
#ERCOT now showing an 80 gigawatt peak Monday morning. All time Jan. record is <66GW. For now, ERCOT forecasts plenty of spare capacity. I don't currently anticipate problems but I'd feel a lot better if we had increased energy efficiency the last few years. #txlege #txenergy pic.twitter.com/kbpMcX39JV

Current ERCOT demand forecast for next Tuesday morning has us setting a new *all-time* peak demand record, beating this past summer's peak by about 40 MW!

Still showing plenty of resources to meet that demand, but it is going to be cold Texas! 🥶🥶🥶 pic.twitter.com/OEmqDhI2fu
Meanwhile,
Battery storage connected to California's grid (@California_ISO) is now over 13% of peak demand in (7 GW vs 52 GW peak). And they added 1 GW in November & December 2023 alone. This happened fast! https://t.co/pLK7HurVbj

I’d worry more about New York and the NE.
A reminder to the electricity pedants: While home and EV batteries are rated by storage capacity (kWh), grid batteries from the perspective of the grid are rated by the amount of power they can feed in (kW or MW).
