PNM 1st to fully integrate solar storage with grid

A small solar plant and its experimental battery storage system went live in Albuquerque on Monday in what Public Service Company of New Mexico said was the first solar storage installation in the country to be fully integrated with a utility's power grid. The storage system consists of 1,280 advanced lead acid batteries housed inside eight climate-controlled containers. It can store about 250 kilowatts, or half of the 500 kilowatts of power generated by an adjacent 2,158-panel solar array constructed as part of the project.
