The Littleton Zoning Board will continue to hear from residents at a hearing Tuesday about a proposed battery storage project.

Battery energy storage systems use rechargeable lithium ion batteries to store electricity from the grid when prices are low.

New Hampshire regulators have given Liberty Utilities final approval to test a first-of-its-kind home battery storage project.

Liberty will sell Tesla Powerwall batteries to 500 of its customers in Southeastern New Hampshire and the Upper Valley.

Spokesman John Shore says the batteries will charge overnight, storing power when demand and rates are lowest. They can also be charged with solar power installed at the user's home.
