This is without grid connection. If grid connected, and wholesale exported electricity revenue of 15c/kwh on cold sunny winter day or summer heat wave (72 days potential) would be 3.7 times more profitable than H2 electrolysis (assuming only $2/kg revenue), and generate over $1000/kw. Recent winter storm in PJM area spiked to $3/kwh. It wasn’t necessarily sunny during spike, but if there is a wholesale participation contract, paying employee BEV owners a huge premium is still way more than 15c/kwh. There were very cold sunny places with $1/kwh after the storm. Can consider closing the datacenter those days, but the large battery, can also monetize peak scarcity during the storm.
