The 700hp ammonia compressor motors draw up to 1,100 amps of 480 on start up and they cycle on and off all the time.
500hp motors draw 500 to 700 amps depending on if they are driving compressors or turbo fans.
We don't use batteries.
Bank maintenance would cost more than it would save.
I work for a NG distribution company where i work directly with meters and consumption data. We have several ethanol producers that use around 400,000 cubic feet of gas per hour, typical house furnaces use 100 cubic feet per hour and run intermittently. A small efficiency increase goes a long way.

If these chargers are going to deliver 350kw, they pretty much have to be installed near hv transmission lines. Even at 7kv street lines it would pull 50 amps if it were a perfect conversion.
