METHOD AND SYSTEM FOR LOAD SHIFTING

摘要

There is provided a system for storing electrical energy during an off-peak period and distributing the electrical energy to consumers during a peak period. The system includes an energy storage means for storing the electrical energy; a first means for directing the electrical energy produced during the off-peak period into the energy storage means; and a second means for directing the electrical energy from the energy storage means to consumers during the peak period. Preferably, the energy storage means consists of five sodium-nickel-chloride batteries having a specific energy in the range of about 80 to about 200 Wh/kg, preferably about 100 to about 150 Wh/kg, and most preferably about 120 Wh/kg.
