Residents in New London County, CT who request quotes on the EnergySage Marketplace spend an average of $315 monthly on electricity. That adds up to $3,780 per year. A different way to look at it is that a typical New London County, CT resident uses 1,032 kWh of electricity per month and 12,384 kWh over the year.
(For what it’s worth: New London County, CT residents shopping for solar on EnergySage may use more electricity than a typical household.)
The easiest way to compare electricity costs across regions is to look at the electricity rate. In the U.S., residential rates generally range from 11 ¢/kWh all the way up to 34 ¢/kWh.
As of February 2026, the cost of electricity in New London County, CT is 31 ¢/kilowatt-hour (kWh)—roughly 54% higher than the national average cost. That number is based on real-world electric bills shared with EnergySage over the past 12 months. You can compare that number to the most recent average state electric price reported by the U.S. Energy Information Administration (EIA).
In Connecticut, there are two primary electricity companies that provide transmission and distribution: Eversource Energy and United Illuminating (UI). These companies are Investor Owned Utilities (IOUs).
Some towns and cities also have access to municipal electricity via publicly-owned organizations, which aren’t subject to the same requirements as IOUs. While they can sometimes give you lower rates, they typically don’t offer any benefits like net metering.
The electricity market in Connecticut is deregulated, which means that even though you can’t choose your utility company, you can choose the company that ultimately supplies your electricity. This gives you the opportunity to potentially save on your electric bills.
While it’s currently not possible to participate in Community Choice Aggregation (CCA) programs in Connecticut, CCA legislation has been introduced in the state as of 2020, so you may be able to take advantage of lower utility rates sometime in the future.

When you pay your electric bill, you’re not only covering the costs to produce that electricity, but also the costs of running and maintaining the electrical grid, as well as public benefit funds that promote things like renewable energy and energy efficiency.
Electric bill costs are rolled into fixed (monthly customer charges) and variable charges (¢/kWh that you use).
Fixed charges, like the flat fee for having a meter, generally remain the same monthly unless your utility makes a policy update.
Your variable charges will change every month and depend on your electricity rate and how much electricity you use.
Your electric bill's variable charges will include a supply (or generation) charge and a transmission and distribution (or delivery) charge. The supply charge covers the cost of electricity generation, while the transmission and distribution charges cover the cost of delivering it to your home.
In Connecticut, most residents have the choice to sign up for variable-rate plans—usually time-of-use (TOU) rates or demand charge plans—which can help you further reduce your electric bills if used in tandem with a solar and/or a battery.
How clean is the electricity in Connecticut?
It’s not easy to come up with an exact number, but according to the U.S. Energy Information Administration, as of August 2025, about 61% of the electricity on Connecticut’s utility grids still comes from natural gas. While 34% comes from nuclear power, only 4% comes from renewable sources. So, if you want to reduce your carbon footprint, going solar in Connecticut can really make a difference.
Depending on your electricity supplier, you can also opt to pay a little bit more to ensure that most (or even all) of your electricity comes from renewable sources. While this won’t help you save money (though it’s possible if you participate through certain municipal group-buy programs), it’s a good alternative if you want to shrink your carbon footprint but are unable or unwilling to install solar panels.
As long as you have a suitable roof, one of the surest ways to save on energy is to go solar—ideally with a vetted contractor offering a competitive price.
Solar panels will reduce or even eliminate your electric bills in the short term and protect you against rising electricity costs in the long run, too. The amount you save depends on how much you spend on electricity now and how much of your electric bill you can offset with solar energy.
Solar panels are a big investment, but New London County, CT homeowners who install them—and pay upfront—break even after an average of just 9.26 years. Then, the solar panels will continue to produce free electricity for years to come.
Does Connecticut offer net metering?
On sunny days, your solar panels will likely generate more than enough power to fulfill your home’s needs at any given moment.
But it doesn’t go to waste. While Connecticut no longer offers net metering, there are other ways to earn credit for all the extra energy you generate.
If your solar panel system is connected to the grid and is less than or equal to 25 kW, you can participate in the Residential Renewable Energy Solutions (RRES) program, either via the Netting Tariff or the Buy All Tariff. The Netting Tariff is most similar to net metering, and it even lets you roll over your energy credits indefinitely, while the Buy All Tariff gives you cash and/or energy credits for your surplus energy.
Whichever tariff you pick, you’re locked into your choice for 20 years.
How much can you save with solar?

Your solar savings depend on you
How much your utility company charges for electricity is a big indicator of how much you'll save with solar. But your exact solar savings depend on your unique situation—including your energy usage, roof layout, system size, and how you pay for your system.
Here are some reasons your savings could be below average:
You don’t use much electricity, or your roof is small or has a less-than-ideal layout. You might have a relatively long payback period, so you'll save a little less over time.
You don't install enough solar panels to 100% offset your energy use. You’ll pay less up front but save less in the long run.
You finance your solar panel system with a loan or sign a lease or power purchase agreement (PPA) instead of paying up front. These types of arrangements can make a lot of sense for keeping your capital flexible and will allow you to start saving sooner. But they will cut into your long-term savings.
Choosing a high-quality solar installer is the key to getting a top-notch solar panel system that will help you save on electric bills.
