Duke Energy Corp., the largest U.S. utility owner, said the world’s biggest battery power storage system has begun operating at the company’s 153-megawatt wind farm in west Texas.
The 36-megawatt Xtreme Power Inc. system can release stored power from the Notrees Wind project when needed and absorb it during times of low demand, Charlotte, North Carolina-based Duke said in a statement today. Closely held Xtreme Power will manage the unit at the facility, which sells electricity to Wal-Mart Stores Inc., the world’s largest retailer.
