EIA's 2024 Form 861 census lists 3 operating companies behind Eversource Energy (NSTAR Electric Company, utility 54913; Connecticut Light & Power Co, utility 4176; Public Service Co of NH, utility 15472), together serving 2,937,403 residential accounts (bundled plus delivery-only) in MA, CT, NH across 29 counties. Weighted across those companies, the 2024 average realised residential price for bundled service was 27.73 cents per kWh (total residential revenue divided by total residential sales). The spread runs from 22.65c (Public Service Co of NH, New Hampshire) to 29.91c (NSTAR Electric Company, Massachusetts). These are annual averages of what customers actually paid, including fuel and rider charges, so they will not match the tariff rate on a current bill; the estimated effective rate above is the site's forward-looking figure.
