Completed in December 2003, the BESS is one of GVEA's initiatives to improve the reliability of service to GVEA members. In the event of a generation or transmission related outage, it can provide 27 megawatts of power for 15 minutes. That's enough time for the co-op to start up local generation when there are problems with the Intertie or power plants in Anchorage. One of the requirements for construction of the Intertie was a reactive power supply capable of delivering power should generation fail. At the heart of the world's most powerful energy storage battery are two core components: the Nickel-Cadmium (Ni-Cad) batteries, developed by Saft, and the converter, designed and supplied by ABB. The converter changes the batteries' DC power into AC power ready for use in GVEA's transmission system. Awards Received: - ABB was awarded the Platts 2003 Global Energy Award for their design and development of the BESS converter. - The Electric Power Resarch Institue Technology Award for the BESS project at the National Rural Electric Cooperative Association Annual Meeting on February 15 2004. - Guiness World Record certificate acknowledging that the BESS is the world's most powerful battery on December 10, 2003. During a test of its maximum limit, it discharged 46 megawatts for five minutes Statistics: - 13,760 liquid electrolyte-filled Ni-Cad cells - Each battery is roughly the size of a large PC and weighs 165 pounds - Total BESS weight - 1,500 tons - Batteries have an anticipated life of 20-30 years - Can be run at 46 MW for for as long as five minutes - Operates at over 5 kV DC
