Liberty Utilities (Granite State Electric) Corp, doing business as Liberty Utilities, filed a request with the New Hampshire Public Utilities Commission to start a battery storage pilot program for up to 1,000 residential customers.

In the Nov. 30 filing, the utility asked regulators to authorize the purchase and installation of batteries and related equipment, with the primary goal of saving transmission costs.

The Algonquin Power & Utilities Corp. subsidiary proposed a monthly charge on the participating customers to cover a portion of the battery systems' costs, a time-of-use rate for participating customers, and to include recovery of the investments in rate base in the next rate case filing.
