Eversource UI Electric Rates Decrease May 1 2026
Summary
PURA conditionally approves decreased electric rates for Eversource Energy and United Illuminating (UI) effective May 1, 2026 through April 30, 2027 in PURA Dockets 26-01-03 and 26-01-04. Eversource residential customers will see a decrease of 4.3 cents per kilowatt-hour, averaging about $30 less per month; UI residential customers will see a decrease of 4.9 cents per kilowatt-hour, averaging about $34 less per month. The reductions are driven by lower public benefits charges tied to Millstone and Seabrook nuclear energy contracts and decreased hardship protection costs including uncollectible debt and arrearage forgiveness programs. A prudence review of actual revenues and expenses may result in further adjustments effective September 1.

What changed
PURA's decisions in Dockets 26-01-03 and 26-01-04 conditionally approve reduced electricity rates for both Eversource Energy and United Illuminating for the 12-month period beginning May 1, 2026. The rate decreases affect six RAM components including NBFMCC, TAC, SBC, CTA, ESI, and RDM. Eversource customers receive an average monthly bill reduction of $30; UI customers receive $34. Ratepayers may compare standard service rates against third-party supplier offers on energizect.com. PURA will conduct a prudence review of actual revenues and expenses from the prior calendar year and may adjust approved rates effective September 1 if warranted.
For Eversource and UI customers, this represents a net decrease in electricity costs for the coming year driven by lower nuclear contract charges and reduced hardship protection costs. Both utilities should ensure billing systems reflect the new rate structure by May 1 and communicate the reduction to customers. Energy consumers in Connecticut may also benefit from comparing rates on the state's official generation rate board to identify potentially lower-cost third-party supplier alternatives.

PURA Announces Electric Rate Adjustments to Take Effect May 1
(NEW BRITAIN, CT – April 22, 2026) – The Connecticut Public Utilities Regulatory Authority (PURA or the Authority) today conditionally approves decreased rates for Eversource Energy (Eversource) and United Illuminating (UI) via their Rate Adjustment Mechanisms (RAM), effective May 1, 2026, through April 30, 2027.
Today’s interim decisions in PURA Dockets 26-01-03 (Eversource) and 26-01-04 (UI) result in lower rates for customers of both companies. Specifically, Eversource residential customers will see rates decrease by a total of 4.3 cents per kilowatt-hour or about $30 on an average monthly bill. UI residential customers will see rates decrease by a total of 4.9 cents per kilowatt-hour, or an average monthly decrease of about $34.
PURA’s approved rates are specific to six RAM components: Non-Bypassable Federally Mandated Congestion Charge (NBFMCC), Transmission Adjustment Clause (TAC), Systems Benefit Charge (SBC), Competitive Transition Assessment (CTA), Electric System Improvements Tracker (ESI), and Revenue Decoupling Mechanism (RDM).
Lower public benefits charges drive the decreases announced in today’s rulings, particularly those tied to the nuclear energy contracts with Millstone and Seabrook. An additional contributing factor to the reduced rates is the decrease to the hardship protection costs for both companies, which include the costs of uncollectible debt and arrearage forgiveness programs.
The Authority reviews and provisionally approves rates effective May 1 for the ensuing 12-month period using actual costs from the previous calendar year as a proxy for expected costs, while adjusting for known and measurable changes. The Authority also performs a detailed prudence review of actual revenues and approved expenses from the prior calendar year and may, if appropriate, adjust the approved rates effective September 1.
As a reminder, ratepayers can compare Eversource and UI standard service generation rates to licensed third-party electric suppliers' current offers on Connecticut's official generation rate board at www.energizect.com.
