AES Corp., the biggest operator of electricity-storage systems, is now seeking to sell batteries big enough to substitute for power plants.
The Advancion systems will cost from $10 million to $500 million, depending on size, and will be offered to utilities and renewable-energy developers in arrays as large as 500 megawatts, said Chris Shelton, president of Arlington, Virginia-based AES’s energy storage unit. The company has operated its own battery systems as large as 64 megawatts, enough to supply 51,000 average U.S. homes, in the U.S. and Chile for more than two years.
