relative to limiting new system enrollment and adjusting compliance payments under the renewable portfolio standard program.

HB 1721 limits new renewable energy system enrollment under New Hampshire's Renewable Portfolio Standard (RPS) program. It prohibits any new systems from joining after a six-month window following its effective date (July 1, 2026), restricting eligibility to systems operational before 2026. The bill caps renewable energy certificate (REC) eligibility at 20 years per system, with existing systems already over 15 years receiving up to five additional years of credits. It also requires the Department of Energy to annually reduce Alternative Compliance Payments (ACPs) as the number of eligible systems declines, directly affecting future RPS program funding.
