The Connecticut Light and Power Company, doing business as Eversource, filed a distribution rate case with the Public Utilities Regulatory Authority on July 14, 2026. It seeks about $451 million a year in base distribution revenue, or about $727 million including storm costs from January 2018 to March 2025; as filed, a typical residential customer using 700 kWh would pay about 18% (roughly $32 a month) more. Eversource says the increase would be about 11% (roughly $20) if those storm costs are securitized instead of recovered through base rates. It proposes a four-year performance-based rate plan starting July 1, 2027 with a 10.25% return on equity, and PURA's decision is expected by June 29, 2027.

Who sets Eversource Connecticut's rates
Eversource Connecticut is investor-owned, so it can change its base rates only by filing a rate case with the Public Utilities Regulatory Authority. The commission holds hearings and takes public comment before it rules, and it usually approves less than the company asks for. Fuel and other pass-through charges can change between rate cases.
