An Act increasing opportunities for peak energy storage

HD 2789 modifies Massachusetts' Renewable Portfolio Standard (RPS) rules to require renewable energy facilities seeking credit toward clean energy goals to include energy storage. It directly affects existing and new renewable energy projects (like solar or wind farms) that want to count toward RPS compliance. The bill mandates that facilities must either have installed storage at their site or contractually pair with storage that provides at least 25% of the facility's power capacity for four hours. Existing facilities operating before January 1, 2019, can qualify by adding storage after that date or entering a contractual agreement for storage. This changes eligibility rules but does not create new programs or funding.
