TFA says 100MW, not MWh. So it's not clear if this is the maximum discharge rate or the actual storage capacity.
Side note – I don't think I'll ever stop being annoyed that we use Wh instead of J for things like this, very confusing to people and makes conversions harder.
- kibwen 6y agoThanks, I can't believe I've never realized that Wh and J are measuring the same thing!
- AzN1337c0d3r 6y agoJust to be clear 1 Wh is not 1 J. 3600J = 1 Wh.
- fastball 6y agoYes, a J is technically a Ws (watt-second). Or more accurately, since Joules are the fundamental unit and Watts are a derived unit, a Watt is a J/s (Joule per second)
- abc_lisper 6y agoDamn. Never made that connection. Have a upboat
- reportingsjr 6y agoIt makes a lot of sense to specify energy in Wh in electrical engineering. It's much easier to convert to other useful measurements involving volts, amps, and watts than joules are.

Easier how? A watt-hour is just 3600 joules - the number of seconds in an hour. 1 joule = 1 volt * 1 amp * 1 second 1 watt-hour = 1 volt * 1 amp * 3600 seconds
- lr1970 6y agoActually the article does say that the 100MW is served for about an hour that makes it 100MWh. But I do agree that it is a sloppy journaism to confuse power and energy. Basic high school level physics.
- fastball 6y agoThat was in reference to their Australian installation, not this new Texas one.
