not great, not terrible

Recently had a battery storage facility nixed near where I live because the loudest local residents were panicked about possibilities of leaks of heavy chemicals into the groundwater (which is somewhat fair) and a bunch of less reasonable nonsense. Still, assuming the legit risks can be handled, facilities like these are crucial to future growth in electricity demand.

Batteries are deployed quickly, but high-capacity grid connections can take a decade in the planning phase alone. Everyone wants one, and NIMBYs are quick to oppose them. Locating at a decommissioned nuclear plant is a great solution avoiding this issue

1.4 GW power, 6 GWh capacity 6 GWh is approximately 5 kilotons of TNT equivalent. Would make a big bang should it go off.

Wow this is a massive arbitrage play. Big proponent of BESS but 5 GW of batteries to buy cheap wind and sell at a higher price is a wild bet. Must have a lot of grants and government money for this one to pencil out.

Nice to see it’s being put to good use. I used to fly the rodeo thermals with a glider… Missing the cloud machine :’)

So it can store 6 hours of output of the previous existing nuclear power station.
