NStar to test A123’s storage cell
Would boost access to wind, solar energy
Boston utility NStar is teaming up with A123 Systems to test the Waltham advanced battery maker’s large-scale energy-storage device, a technology that could be key to integrating intermittent energy from wind turbines and solar arrays into the nation’s power grids. Company officials say they plan to install one of A123’s storage devices at an NStar substation in Medway, where it will be connected to the grid and used to capture electricity when supply exceeds demand, and to release it when more power is needed. The technology could be key to integrating intermittent renewable energy sources such as wind turbines and solar panels with the nation’s electric grids.
