Our company is one of the top five buyers of power in the US. We had to shut down several of our large air separation plants in Texas and midwest. I heard that our mil rate, which is usually about $30 to $40 per MWhr went to $9000/MWhr for a few periods. That is how utilities get us to shut down our large plants. We can have anywhere from 10MW to 40MW motors on our compressors with some plants having up to three or four compressors. Fortunately we can run off liquid backup for short durations but if the cold snap lasts more than a day or two, we will need to run to top off tanks.
