What is Demand?
The concept of electricity demand has changed dramatically with restructuring of the electricity markets, which leads to confusion among industry professionals. Demand, in the older definition, referred to monthly peak customer energy use and the associated monthly “demand charge”. In the context of the newer demand response products, demand refers to customer energy use at a particular time independent of the old monthly demand charges.
For decades, integrated electric utilities billed both energy and demand charges for commercial and industrial facilities. Electrical energy, both in the past as well as today, refer to the amount of energy consumption measured in kilowatt hours (kWh). In the older world, demand refers to the rate of energy consumption measured in kilowatts (kW). A common analogy is with transportation, where we distinguish between miles per hour or the rate of travel, and miles driven or the amount of travel. Thus, the rate of demand of 100 kW for a period of 8 hours is an amount of energy consumption of 800 kWh. …
Demand Response Holds Great Market Potential
Significant market potential remains to be captured nationally through demand response. An estimated 47,000 megawatts (MW) of peaking capacity could be avoided nationally through demand response, according to a May 2007 study by the Brattle Group. …
