Cool way to think about GWh/year: 1 GWh/year = (10 ** 9) / 24 / 365.25 / (10 ** 6) MW = 0.11 MW 70 GWh/year = 8 MW 1755 GWh/year = 200 MW 252 GWh/year

252 GWh/year = 29 MW
- amalcon 5mo agoHaha. Reminds me of how volt-amperes are technically the same unit as watts, but if you see VA in an electrical specification you know it means a different thing than it would if you saw W.
- om8 5mo ago> volt-amperes are technically the same unit as watts volt-amperes are joules
- gnabgib 5mo agoVolt-amperes are watts... watts/second are joules https://en.wikipedia.org/wiki/Watt https://en.wikipedia.org/wiki/Watt
- lefra 5mo agoYou got it backwards, Watts are Joules/second (or joules are Watt•second).
- Skunkleton 5mo agoWatts * seconds are joules. Joules is a unit of energy. Watts are power.
- om8 5mo agoOh, yes, you are right about watts. My bad

- epistasis 5mo agoBut not a very relevant for batteries, unless talking about discharge only once a year. Grid batteries are discharged on average 80% per day, if not more. EV batteries... well, probably about 5%-10% per day at most.
