Information & Charts—Previous Year’s Energy Supply & Statistics
West Boylston Municipal Light Plant (WBMLP) is a vertically integrated utility that owns distribution, generation, and transmission facilities. Our investment in generation and transmission assets produces a very clean energy supply with stable and competitive electricity rates. Our generation and transmission expenses represent approximately 75% of our annual operating budget and WBMLP hasn’t had a residential rate increase since 2009.
WBMLP continuously evaluates new sources of reliable, non-greenhouse gas (GHG)-emitting, and low-cost energy located throughout or interconnected to New England. West Boylston is transitioning away from fossil fuel generation and adopted a Greenhouse Gas Emission Standard (GGES) in 2019. Our GGES mandate is “Net Zero” greenhouse gas emissions from our energy supply by 2050.
Over 59.2% of WBMLP's energy supply did not emit GHGs in 2025. This means we are about halfway toward meeting our net-zero GGES goal. Over time, WBMLP will need to invest in additional renewable and clean energy to meet our net-zero GGES goal by 2050.
WBMLP's existing energy portfolio is comprised of nuclear, solar, wind, hydroelectricity, natural gas, oil and storage generation. Typically, our energy assets and contracts require us to purchase specific quantities of energy, through specific dates of the contract. Some of our existing clean energy supply commitments extend until 2057.
