high motor starting loads will peg that meter, and that means a higher rate

in the late 70's and early 80's, all grocery stores had interlocked compressors,
so they couldn't start more than one refer compressor at a time.... if the
tumblers lined up, and a bunch of them hit at once, and pegged the demand
meter, the cost of electricity for that 50,000 sq ft supermarket would be $5,000
higher for that month, and that was in the late 70's.
