After several months of review, the Department of Public Utilities has approved electric sector modernization plans developed by Eversource, National Grid and Unitil.
A climate and clean energy law enacted in 2022 required the investor-owned electric distribution companies to file these plans, known as ESMPs, to articulate how they will contribute to meeting the goal of net zero emissions by 2050.
The comprehensive, five-year plans are meant to ensure that the state’s electric infrastructure will be able to handle increased demand due to further electrification of vehicles, heating systems and other technologies.
The plans include an overview of:
• All approved, reviewed or under-consideration distribution system investments and alternatives
• Distribution system improvements to increase system reliability and resiliency in the face of weather- and disaster-related risks
• Distribution system improvements to facilitate transportation and building electrification
• Forecasts considering five- and 10-year horizons
• An assessment of demand through 2050
Details on planned investments and upgrades for each utility can be found in the DPU’s order approving the plans for Eversource, National Grid and Unitil.
The ESMP process repeats in five-year planning cycles, with each utility expected to provide the DPU with plans by Sept. 11, 2029, to forecast needs from 2030 to 2035. This ongoing work is intended to help shift key sectors away from fossil fuels with properly supported electricity generated through renewable energy.
