Xcel Energy, in partnership with the University of Minnesota, the National Renewable Energy Laboratory and the Great Plains Institute, will soon begin testing a cutting-edge technology to store wind energy in batteries.
The research partners will test a one-megawatt battery storage technology to demonstrate its ability to store wind energy and move it to the electricity grid when needed. Fully charged, the battery could power 500 homes for six and one-half hours. Xcel Energy will purchase a sodium-sulfur battery from NGK Insulators, Ltd. that will be an integral part of the project.
