Charging 20 Teslas at maximum rate sure, but that could also be viewed as fully charging 1600 Teslas per day, or steady state providing the energy for about 12k Teslas (assuming 10-15k miles per year per car). Likewise, based on my own electricity bills, 1k houses is closer to 3000-5000.

Obviously, peak load vs average load is very important so I wouldn’t expect the energy to go that far, but connected to a big battery… probably, right?
