Eversource Electricity Rates in Massachusetts

Eversource serves multiple states, so an “Eversource electricity rate” is not one national or even one New England number. This page focuses on Massachusetts residential electric supply, where Eversource customers can receive Basic Service, participate in an eligible municipal aggregation or choose a competitive supplier. The customer’s exact service area matters because Eastern and Western Massachusetts have different Basic Service rates.

Eversource Massachusetts residential Basic Service: 17.323¢/kWh East; 17.185¢/kWh West

Effective period: August 1, 2026 through January 31, 2027

Interpretation: Massachusetts’ Energy & Ratepayer Advocacy Division publishes separate Eversource East and West Basic Service benchmarks. Delivery charges are separate.

Data checked: August 21, 2026. Recheck the official benchmark before publication if this page is deployed later.

Eversource East and West are not interchangeable

Massachusetts’ summer 2026 consumer guidance lists Eversource East residential Basic Service at 17.323¢/kWh and Eversource West at 17.185¢/kWh for the August 2026 through January 2027 period. A household should therefore confirm which Eversource service area appears on the bill before comparing a competitive supplier or community aggregation. At 1,000 kWh, the supply-only benchmark is about $173.23 in Eversource East or $171.85 in Eversource West. Those are not total bills. Distribution, transmission, public-policy charges and other utility items continue to apply regardless of the supply option.

Three Massachusetts supply paths: Basic Service, aggregation or competitive supply

Massachusetts customers may encounter more than a simple utility-versus-supplier choice. Basic Service is the utility default for customers who do not obtain supply elsewhere. Many cities and towns operate municipal or community-choice aggregation programs with their own rates and renewable content. Customers can also select licensed competitive suppliers where eligible. This makes the best comparison local. A community aggregation can be below Eversource Basic Service for one period and above it after the utility resets. A competitive supplier may offer a fixed rate, but contract fees and renewal terms can matter. BestEnergyDeal should therefore compare all supply options that actually apply at the address rather than treating Basic Service as the only alternative.

Eversource Basic Service resets every six months for residential customers

Eversource states that residential fixed Basic Service changes twice each year, on February 1 and August 1. The August 2026 reset is therefore a dated benchmark, not an evergreen rate. Municipal aggregation contracts can have different term dates, and competitive-supplier contracts can be shorter or longer still. For an up-to-date decision, use Massachusetts electricity rates together with the Massachusetts DPU’s Energy Switch website. If the service address is in New Hampshire rather than Massachusetts, do not use the rates on this page; the state’s default-energy-service rules and Eversource benchmark differ. Our prepared New Hampshire electricity rates page covers that market separately.

How to compare Eversource with a third-party supplier

Start by identifying Eversource East or West, then note the current Basic Service rate and any community aggregation available in the municipality. For a competitive supplier, compare the fixed or variable price, contract term, cancellation fee, renewable content and automatic renewal language. A supplier rate below 17.323¢ in Eversource East can be cheaper on the supply line today, but future Eversource Basic Service resets may change the comparison.

Renewable content can be a separate purchasing decision

Massachusetts has detailed renewable-energy requirements, and community aggregation programs often offer multiple renewable-content levels. A household may intentionally choose a product that costs more than Basic Service in exchange for additional eligible renewable content. BestEnergyDeal should show that as a preference-based tradeoff rather than labeling every higher-priced green product as a bad deal. See our renewable electricity plans guide for how supply pricing and renewable attributes interact.

Editorial note on Eversource geography

Eversource is a multi-state utility brand. BestEnergyDeal should never infer the market from the company name alone. The service address must resolve to a state and, in Massachusetts, to the relevant East or West territory before showing a Basic Service benchmark. This geographic check is as important as the rate itself because the same brand can represent different regulatory systems and supply prices.

Using this Eversource Electricity Rates in Massachusetts page responsibly

This page is designed as a decision framework rather than a promise that a specific supplier will always beat the utility. Electricity supply benchmarks, tariff components and competitive offers change. Verify the current utility bill and official market source immediately before enrollment, and compare products at the same usage level and over the period for which rates are actually known.

Why East and West territory labels matter

Massachusetts customers should confirm whether their bill is in the Eversource East or West territory before using a Basic Service number. A small difference in cents per kWh can still affect a long-term comparison, and the territory label also helps prevent the Massachusetts rate from being confused with Eversource service in Connecticut or New Hampshire. BestEnergyDeal should always keep state, territory and effective dates attached to the benchmark.
