Abstract:
Large facility owners generally negotiate yearly or
multiyear electric service agreements and often are
given lower base rates in exchange for sharing the risk
of price fluctuations. This agreement may take the form
of a capped rate, or may go as far as a real-time market
rate where the facility owner sees every price spike in
the electric market. Price spikes due to normal summer
heat, as well as unforeseen events such as power plant
emergency shutdowns, occasionally can reach five times
the base utility rate, or higher. The challenge for the
facility owner is how to reduce power consumption during
periods of peak pricing, while maintaining mission
critical building loads.
