Connecticut Electricity Rates in July 2026: What Eversource Customers Should Know

Eversource's standard supply rate is 11.57 cents per kilowatt-hour in July 2026. The supply rate is only part of your bill - Connecticut's total average electricity cost of 32.24 cents per kilowatt-hour is 54 percent above the national average, and understanding what drives the difference matters for managing costs.

What Eversource's 11.57-Cent Supply Rate Means for Your Bill

If you look at your July 2026 Eversource bill, the supply rate - labeled as the standard service charge - is 11.57 cents per kilowatt-hour. This is the generation portion of your electricity cost: what Eversource charges for the electricity itself, purchased on your behalf from generation sources on the New England regional grid. What it is not is the total cost of electricity delivered to your home.

By the time delivery charges, transmission charges, distribution charges, state conservation program charges, renewable energy charges, and other line items are added, the total cost of electricity for a Connecticut Eversource customer reaches roughly 32 cents or more per kilowatt-hour. The U.S. Energy Information Administration puts Connecticut's average total residential electricity rate at 32.24 cents per kilowatt-hour as of mid-2026. That makes Connecticut one of the most expensive electricity states in the country, 54 percent above the national average.

For a typical Connecticut household using 700 kilowatt-hours per month - roughly the state average - a 32.24-cent average rate means a monthly electricity bill of approximately $226. At 850 kWh, which is closer to what Connecticut households with electric heating use in winter, that rises to approximately $274. These are not outlier bills. They are what typical Connecticut households pay at current rates. Understanding this baseline matters because it determines what any efficiency investment, solar installation, or behavioral change actually saves you.

Why Connecticut Electricity Is 54 Percent Above the National Average

Connecticut's high electricity rates have multiple causes, and understanding them clarifies which costs are within a homeowner's control and which are not. The largest contributor is infrastructure cost. Connecticut has an aging transmission and distribution system that requires significant ongoing investment to maintain reliability. The costs of that investment - grid hardening, pole replacement, underground cable installation, substation upgrades - are recovered through delivery charges that all customers pay regardless of how much electricity they use. These infrastructure charges are embedded in every Connecticut electricity bill.

State-mandated program charges are a second significant driver. Connecticut has an aggressive renewable energy portfolio standard, a comprehensive energy efficiency program funded through the Regional Greenhouse Gas Initiative, and several state-mandated programs assessed as per-kilowatt-hour charges on all electricity consumers. These programs serve real purposes and have reduced emissions and funded efficiency upgrades for low-income households, but they add cents per kilowatt-hour to every Connecticut electricity bill - costs that are not present in lower-rate states.

Transmission costs are the third major component. New England is a regional electricity market, and Connecticut is at the end of long transmission lines that bring power from generating facilities elsewhere in the region. The cost of moving electricity across the regional grid is allocated to load-serving utilities including Eversource and passed through to customers. None of these cost components are within a typical homeowner's direct control. What homeowners can influence is the quantity of electricity they consume, and for high-consumption households, reducing consumption is where the largest bill savings lie.

What Tolland County Homeowners Can Do to Manage Electricity Costs

Connecticut electricity rates create a strong economic case for efficiency investments that reduce consumption, and for generating electricity on-site through solar. At 32 cents per kilowatt-hour, every kilowatt-hour eliminated or generated on-site represents real monthly savings. Whole-house electrical efficiency upgrades - switching to LED lighting if not already done, replacing aging appliances with Energy Star-certified models, and adding smart occupancy controls to high-use areas - reduce baseline consumption across all hours. These steps are not dramatic, but at 32 cents per kilowatt-hour, each kilowatt-hour eliminated saves real money every month.

Electric vehicle charging timing is a significant lever for EV households. Eversource offers time-of-use rate structures for qualifying customers. Charging an EV during off-peak hours - typically late night - rather than evenings when grid demand is high can reduce the effective cost of EV charging substantially. TJF Electric installs Level 2 EV chargers with smart-charging capability that can be programmed to charge only during off-peak windows, maximizing savings without requiring the driver to manage timing manually.

Solar generation remains economically compelling in Connecticut even with the 3.25-cent non-bypassable charge added in 2026 for new systems. Generating electricity on-site at a solar system's amortized cost is substantially cheaper than buying it from Eversource at 32 cents per kilowatt-hour. Panel upgrades for solar readiness, EV charger installation with off-peak programming, and whole-house surge protection are all services TJF Electric provides in Tolland County and Eastern Connecticut. Call us for a free estimate if you are evaluating any of these improvements.

5 Ways Tolland County Homeowners Can Reduce Their Electricity Bills in 2026

At 32 cents per kilowatt-hour, every efficiency improvement has a real dollar value in Connecticut. These are the most impactful steps for Tolland County and Eastern CT homeowners.

1. Program your EV charger for off-peak hours: EV charging draws 32 to 48 amps continuously and adds significant electricity costs if done during peak evening hours. A smart Level 2 charger programmed to charge between 11 PM and 6 AM takes advantage of lower grid demand and, for customers on time-of-use rates, lower supply rates. TJF Electric installs Level 2 chargers with off-peak programming capability.
2. Upgrade to LED lighting if you have not already done so: LED bulbs use 75 to 80 percent less electricity than incandescent bulbs and last 15 to 25 times longer. At 32 cents per kilowatt-hour, the savings from a full-home LED upgrade are more significant in Connecticut than in lower-rate states. If your home still has any incandescent fixtures, replacing them is one of the cheapest efficiency investments available.
3. Evaluate solar with accurate billing simulations: At 32.24 cents per kilowatt-hour, solar generation has high value in Connecticut. Solar payback periods in CT are among the shorter ones in the Northeast for this reason. Homeowners evaluating solar in 2026 should request billing simulations that include the 3.25-cent non-bypassable charge for new systems and compare payback scenarios with and without battery storage.
4. Insulate and air-seal to reduce HVAC load: Heating and cooling accounts for roughly half of household electricity use in Connecticut homes with electric HVAC. Attic insulation and air sealing are often the most cost-effective ways to reduce HVAC consumption. Connecticut provides incentives through the Energize CT program for qualifying insulation and air sealing projects.
5. Have your electrical panel evaluated for efficiency upgrade readiness: Older electrical panels can have implications for what efficiency upgrades they can support and whether they are suitable for modern loads. A panel evaluation by a licensed electrician can identify whether your panel is limiting efficiency improvements like solar readiness or EV charger installation. TJF Electric performs panel evaluations in Tolland County.

Frequently asked questions

What is the difference between the supply rate and the delivery rate on my Eversource bill?

The supply rate - 11.57 cents per kilowatt-hour in July 2026 for standard service - is the charge for the electricity generation itself. The delivery rate covers the cost of moving electricity from the regional grid to your home through Eversource's distribution system. Both rates are charged per kilowatt-hour, but they cover different parts of the electricity value chain. The total of all charges on your bill is what determines your effective cost per kilowatt-hour.

Is the Eversource supply rate the same in all parts of Connecticut?

Eversource serves most of Connecticut and applies the standard service rate across its service territory.
