Time to take a second look at conservation voltage regulation?Intelligent Utility, June 4, 2013
Voltage regulation has been a critical part of power system operation since Thomas Edison first lit electric lights over Menlo Park on New Year’s Eve in 1880. For many years, electric utility companies initiated load reductions during critical peak load periods by reducing voltages delivered to air conditioners, home appliances and industrial machinery.
Conservation voltage regulation (CVR) was implemented manually by reducing voltages at the substation to achieve a 1% power savings over short periods. (These same utilities routinely operated at the high end of the 114-126 voltage range permitted by American National Standards Institute (ANSI) Standard C-84.1 due to limitations in technology.)
