Compiled by the Portland Clean Energy Task Force

Please note that this list is intended as a guide towards programs designed to save on energy costs. Due diligence is a must, so research carefully and be aware that programs change frequently!

Inflation Reduction Act (IRA). Recent Federal legislation will end many clean energy incentives for homeowners and businesses by the end of this year. Use the links above… time is short.

Home Energy Solutions (HES) visit, usually $75, is currently being waived (!). This is a fast way to reduce your energy bill. The income eligible (HES IE) is free to low income households. Additional incentives become available upon HES completion, and these can amount annually to several hundred dollars. Programs are here for United Illuminating customers, and here for Eversource. An HES visit also creates a Home Energy Score that summarizes how energy efficient your home is.

As mentioned above, get started through Portland’s HeatSmart campaign.

​

Solar. The 30% federal tax credit for residential new purchased solar systems and/or energy storage will expire 12/31/25. Specifically, a system that you pay for upfront will need to be paid in full by that date to be eligible for the credit, even if it is installed in 2026. Solar arrays installed through a leasing option will have a few years to go (end of 2027) before incentives for that option are eliminated. Please verify this with a vendor. 

          The credits for Commercial solar projects will also be drastically reduced, then eliminated, after December 31, 2027. 

Home Energy Storage (Batteries). CT still has rebates for purchasing residential energy storage. They can be found at Energy Storage Solutions, Eversource, and UI. Once installed, there are further incentives for allowing the Utilities to draw from your batteries during certain high demand periods. Both utilities have energy storage programs for commercial users. 

          Unfortunately, the federal legislation also eliminates the 30% federal tax credit for this after 12/31/25.

Electric Vehicle Incentives. The EV Club of CT has a thorough explanation of the end-of-incentives for EVs and EV Chargers. There are federal and state EV purchasing incentives.

          Federal legislation eliminates federal purchase rebates for EVs (by Sept 30, 2025), but CT’s low income rebates remain. Until the end of this year, Eversource and United Illuminating offer incentives to offset the equipment and installation costs of an EV charger. 

          Programs to compensate you for charging outside of high demand periods looks like it will remain.

Smart-E Loans for Energy Upgrades. CTGreenBank loans cover many upgrades for Heating & Cooling, Water Heaters, Insulation, Windows, Solar, Battery Storage, EV Chargers, Asbestos & Mold Removal, Energy Star Appliances, Roof prep for solar, and Tree Removal for Solar.

These remain solid, Thankfully.

Rebates for Energy Upgrades. Commercial, Residential, and Multifamily buildings can receive rebates for some energy upgrades through EnergizeCT.com. An HES visit may be required.

These also remain solid, Thankfully.

Energy Assistance Programs. From PACE, an excellent compilation of programs designed to assist households in need.

 

CPACE (Commercial Property Assessed Clean Energy). CPACE is a financing mechanism for energy efficiency, renewable energy, or other related projects. Repayments are made via an assessment on the property tax bill.
