ABB’s BESS (battery energy storage system), which occupies an area larger than a soccer field, is composed of 13,760 nickel-cadmium energy cells in four strings.
The BESS was built for Golden Valley Electric Association (GVEA), an energy cooperative serving the area around
That’s important in an area where temperatures dip to -50 C and water pipes can freeze in two hours. In an emergency, the BESS can deliver 27 megawatts of power for 15 minutes – enough to power 10,000 households – and up to 46 megawatts for shorter periods.
ABB designed the power conversion system, metering, protection and control devices, and service equipment. The Ni-Cd cells were made from primary and recycled cadmium by battery maker Saft.
Platts’ Global Energy Awards recognised ABB with the 2003 Engineering Project of the Year for its work on the BESS project.
