Why Eversource Rates Dropped in 2026
PURA credited the May 1 decrease to lower public benefits charges, especially those tied to the Millstone and Seabrook nuclear contracts, and to lower hardship protection costs. PURA called the approvals interim and conditional.
The July 1 supply change added more relief. The OCC estimates a $30.78 monthly decrease from May and a further $7.45 decrease from July for a customer using 700 kWh a month.
Eversource Rate Increases Coming in 2027
January 1, 2027 Supply Rate
Standard service rates change every January 1 and July 1. Eversource sets its January rate in a filing with PURA, expected in mid-November. Grid Shopper projects about 15.2 cents per kWh, with a range of 14.6 to 15.6 cents. That is a third-party estimate, not an official rate.
July 2027 Delivery Rate Request
Hartford Business Journal reports Eversource is seeking $503 million in added annual revenue. Here is what the request means:
- About an 11% increase on the average customer’s total bill.
- About 13% for a typical home using 700 kWh a month.
- A final PURA decision not expected until mid-2027.
- Increases beginning in July 2027 if approved.
This is a request. PURA has not approved it.
Eversource CT Rate Per kWh: What You Pay
The OCC lists Rate 1 residential charges that include:
- Supply: 11.58 cents per kWh. You avoid this charge by choosing a third-party supplier, who then bills you their rate.
- Transmission: 5.050 cents per kWh.
- Distribution: 5.844 cents per kWh.
- Electric System Improvements: 2.031 cents per kWh.
- Competitive Transition Assessment: 0.496 cents per kWh.
- Customer service charge: $9.62 a month.
- Public benefits credits: 2.061 cents per kWh on the Non-Bypassable FMCC and 0.103 cents per kWh on the Systems Benefits Charge.
You pay transmission, local delivery, and public benefits no matter which supplier you pick. Add these lines and the smaller program charges, and our estimate comes to about 23 cents per kWh before the fixed monthly charge. That is our math from OCC figures, not an Eversource number.
How Connecticut Compares With Other States
Connecticut’s average residential price was 24.51 cents per kWh in August 2026, against a U.S. average of 18.16 cents, according to the U.S. Energy Information Administration. That ranked Connecticut 10th highest among states. One year earlier, the Connecticut average sat at 30.17 cents.
How to Lower Your Eversource Bill
- Watch your supply rate. Compare it each January and July.
- Trim your usage. Smart thermostats, LED lighting, and Energy Star appliances all cut kWh.
- Know your options for help. Connecticut residents with high bills should review state energy assistance.
- Produce your own power. Solar reduces the kWh you buy from the grid at each new rate.
How Solar Protects You From Eversource Rate Increases
Every rate increase raises the price of each kWh you buy from the grid. Each kWh your panels cover is one you avoid buying at that new price. Solar does not erase your Eversource bill. Learn how solar panels work at night and how solar works with your electric bill.
Steps to Take Before You Go Solar
- Review your bills. Pull 12 months of Eversource bills to see your real usage.
- Check your roof. Age, orientation, and shading drive production. Replace an older roof before panels go on.
- Know the program. Connecticut’s RRES program replaced legacy net metering and pays through Buy-All and Netting tariffs.
- Compare financing. Cash, a loan, or LightReach each change your monthly math.
