WBMLP's 2021 Energy Supply

Information & Charts Summarizing our 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 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 GGESS goal is “Net Zero” greenhouse gas emissions from our energy supply by 2050.

54% of WBMLP's energy supply did not emit GHGs in 2021. This means we are halfway toward meeting our net-zero GGES goal already! 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.

54% of West Boylston's energy supply met our Greenhouse Gas Emission Standard (GGES), which requires "Net-Zero" Greenhouse Gas Emissions by 2050:

2021 GGES Qualified Energy
(Emits "0" GHG Emissions)
MWh's Owned or Purchased Percentage of Annual Power Supply Environmental Attributes
Hydro-Quebec Hydroelectricity, Canada 2,628 4% Attestation
Brookfield Hydro & REC, New Hampshire 604 1% REC
NYPA Hydro, New York 3,079 5% Attestation
Nuclear, Millstone 3, Connecticut 8,152 14% EFEC
Nuclear, Seabrook, New Hampshire 17,881 30% EFEC
Net Meter Solar & RECs from Customers (N4) 30 0.05% REC
Total 2021 GGES Qualified Energy Purchased 32,374 54%  

10% of West Boylston's Energy Supply generated environmental attributes that we sold in 2021. WBMLP will eventually retire these environmental attributes, which we then can count toward our GGES percentage:

2021 Environmental Attributes Sold by WBMLP & Future Retirement Date MWh's Owned or Purchased Percentage of Annual Power Supply Environmental Attributes REC Retire Date
West Boylston Solar 390 1% REC 2022
West Boylston Landfill Community Solar 1 2,400 4% REC 2026
West Boylston Rooftop Community Solar 2 1,177 2% REC 2028
Berkshire Wind, Massachusetts 2,332 4% REC 2030
