Altair Nanotechnologies, a Nevada company that makes high-powered battery systems, has completed validation testing of a two-megawatt, 500 kilowatt-hour battery system that holds real promise in the effort to find a way to store energy and feed it in reliable increments to the nation’s electrical grid.
The system, purchased by AES Corp., was tested at a substation owned by Indianapolis Power & Light.
Developers hail it as a big step toward commercial deployment of grid-scale energy storage systems.
If things stay on track, the system could help utilities move toward greater use of wind and solar power generation. A summary of the validation report tells how they did it.
