Stamford Electricity Prices
Stamford residents pay some of the highest electricity rates in the country — and costs have only gone up in recent years.
Connecticut’s average electricity rate jumped from 21.9 cents per kWh in 2021 to 28.8 cents per kWh in 2024 — a roughly 31.5% increase in just three years. That’s nearly double the national average of 16.5 cents per kWh.
Solar panels can help Stamford homeowners offset these rising costs. By generating your own electricity at home, you rely less on the grid — and less on rates that have consistently climbed year after year.
Over the long term, solar can provide a more predictable energy cost. While utility rates continue to rise, the electricity your solar panels produce stays yours — helping protect your household budget for years to come.
Price of Energy: Connecticut vs National Average
Stamford Area Utility Providers
Eversource is the primary electric utility serving Stamford, CT. Based on 2023 data — the most recent available — Eversource customers paid 31.6¢ per kWh, nearly double the national average of 16.0¢ per kWh.
Connecticut’s high rates stem from aging grid infrastructure, heavy dependence on natural gas, and significant transmission costs. These factors push Stamford’s electricity bills well above both state (29.90¢/kWh) and national averages.
When local rates are nearly twice the national average, generating your own electricity becomes a meaningful consideration. For Stamford homeowners, solar panel installation can be a practical way to offset high utility costs.

Connecticut Solar Incentives
Stamford homeowners have access to several solar incentives in Connecticut that can meaningfully reduce the cost of going solar — from tax exemptions to bill credits.
Connecticut offers four key incentives for residential solar: a net metering and solar tariff program, a full sales tax exemption, a property tax exemption, and a community solar program for those who can’t install panels directly.
Note that the federal residential solar tax credit was recently eliminated. State incentives still apply. Homeowners who lease through LightReach may benefit further, as Palmetto handles the commercial tax credit and passes savings through lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Residential Renewable Energy Solutions (RRES) Program | Net Metering / Solar Tariff | Connecticut’s statewide solar compensation program offering two tariff options — a Buy-All tariff or a Netting tariff — that pay residential solar owners in Stamford for the energy their systems produce and send to the grid. | Learn More |
| Connecticut Sales Tax Exemption for Solar Systems | Sales Tax Exemption | Connecticut provides a 100% sales tax exemption on the purchase of solar energy systems, saving homeowners in Stamford the state’s 6.35% sales tax on all qualifying solar equipment and installation costs. | Learn More |
| Connecticut Property Tax Exemption for Solar Systems | Property Tax Exemption | Connecticut mandates a statewide property tax exemption for residential solar energy systems, ensuring that the added home value from a solar installation does not increase your property tax bill for Stamford homeowners. | Learn More |
| Shared Clean Energy Facility (SCEF) – Community Solar Program | Rebate | Connecticut’s community solar program allows renters, condo owners, and homeowners in Stamford with unsuitable roofs to subscribe to a local solar project and receive 5–15% savings on their electric bill through monthly credits for up to 20 years. | Learn More |
The Residential Renewable Energy Solutions (RRES) Program, administered by Eversource Energy and United Illuminating (UI), replaced Connecticut’s legacy net metering program in January 2022. It is available to residential solar owners in Stamford with systems 25 kW or smaller on properties with one to four units. Homeowners choose between two compensation options: the Buy-All Tariff, where all solar production is exported to the grid at a locked-in rate of $0.3289/kWh for 2026 applications (guaranteed for 20 years), or the Netting Tariff, where solar power first supplies your home and only excess is exported at the retail electricity rate.
For 2026, homeowners on the Netting Tariff should be aware of a new Solar Energy Adjustment charge of $0.0402/kWh applied to total solar production, listed as a line item on your bill. This charge offsets program costs. Both tariff options allow systems with battery storage to participate, and income-based incentive adders are available for households at or below 60% of the state median income or located in an Environmental Justice Community or Distressed Municipality.
To enroll, you must apply through your utility — either Eversource or United Illuminating — and your system must be grid-connected. Once enrolled in the Buy-All Tariff, your rate is locked in for the full 20-year term, providing long-term revenue certainty. The RRES program runs through at least 2027 (a six-year program launched in 2022).
Connecticut offers a 100% sales and use tax exemption on solar photovoltaic systems, solar water heating systems, and solar space heating systems. With the state’s standard sales tax rate of 6.35%, this exemption can save the average Connecticut homeowner approximately $1,662 on a typical residential solar installation — and more on larger systems or those paired with battery storage.
To claim the exemption, the purchaser (homeowner or contractor) must present Form CERT-140 (Solar Heating Systems, Solar Electricity Generating Systems, and Ice Storage Cooling Systems) to the seller at the time of purchase. This form certifies that the equipment qualifies for the tax-exempt status and must be submitted before the sale is completed.
This exemption applies to both residential and commercial solar customers in Stamford, as well as solar installers and contractors purchasing equipment. There is no expiration date currently associated with this exemption, making it a reliable, permanent savings benefit for Connecticut solar buyers.
Connecticut state law requires that all passive and active solar energy systems — including rooftop solar photovoltaic panels — be fully exempt from property taxes. This means that even though a solar installation can significantly increase your home’s market value, that added value will not be assessed or taxed by your local municipality. Based on Connecticut’s median home value and an average property tax rate of approximately 2%, the typical homeowner saves an estimated $544 per year in property taxes thanks to this exemption.
To claim the exemption, homeowners in Stamford must file a claim with your local tax assessor or board of assessors in the town where the solar system is installed. The filing deadline is before November 1 of the assessment year in order for the exemption to take effect for that tax cycle. The exact application form and process may vary slightly by municipality, so contact your local assessor’s office for specific instructions.
This exemption has no expiration date and covers both the equipment and installation costs associated with your solar energy system. It applies to all residential solar installations statewide, regardless of system size or utility provider, making it one of the most straightforward and universally available solar incentives in Connecticut.
The Shared Clean Energy Facility (SCEF) Program, overseen by the Connecticut Department of Energy and Environmental Protection (DEEP), allows residents of Stamford who cannot install rooftop solar — including renters, condo owners, apartment dwellers, and homeowners with shaded or structurally unsuitable roofs — to benefit from solar energy. Participants subscribe to a share of a local, large-scale solar project and receive monthly bill credits of 5–15% on their electricity costs for up to 20 years, at no upfront cost to the subscriber.
The program is specifically designed to expand solar access to low-and-moderate income (LMI) households. Income-eligible customers (for example, single-person households earning under $75,643/year or two-person households under $99,180/year under Eversource’s guidelines) may receive automatic enrollment or priority access. Non-income-eligible residents who simply lack a suitable roof for solar can also subscribe on a first-come, first-served basis.
The SCEF program aims to add 260 megawatts of locally generated renewable energy to Connecticut’s grid over eight years. Subscribers are connected to projects through their existing Eversource or United Illuminating account, and credits appear automatically on monthly bills. There is no equipment to purchase, no installation required, and no long-term financial risk to participants.

Leasing Solar Panels
If you’re not ready to purchase solar panels outright, Palmetto offers a Power Purchase Agreement (PPA) for Stamford homeowners served by Eversource or United Illuminating — the two main utilities in Connecticut. With a PPA, you don’t own the system. Instead, you agree to buy the electricity it produces at a set rate per kilowatt-hour (kWh). That means no large upfront cost, and no responsibility for maintenance or repairs.
With a PPA, your monthly payment varies slightly with the seasons — solar panels produce more in summer and less in winter, so your bill reflects that. Over the course of a year, though, the savings tend to even out. And because Palmetto owns and maintains the system under LightReach, you’re covered if something needs attention — no service calls, no surprise costs.
Compared to paying cash, a PPA removes the need to recoup a large investment or manage system upkeep on your own. You simply use the solar energy your panels produce and pay for what you use at a rate that’s typically lower than what Eversource or United Illuminating charges. It’s a straightforward way to benefit from solar without taking on the complexity of ownership. Learn more about how buying compares to leasing solar to find the option that fits your situation.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!
