Connecticut Non-Residential Renewable Energy Solutions
Non-Residential Renewable Energy Solutions (NRES) is an incentive program that can help you offset the cost of the electricity you buy from Eversource with the energy you generate with non-residential solar or other Connecticut Class I renewable technologies.
This program replaced the Low and Zero Emission Renewable Energy Credit Program.
If you have questions about the NRES Program at Eversource, please email ctcommrenewables@eversource.com or call 844-726-7573.
How it works
The year 3 procurement process was developed via Public Utilities Regulatory Authority (PURA) Docket No. 23-08-03.
In program years 2 and beyond, there will be two opportunities to submit an NRES bid, tentatively scheduled for February and August each year.
The program year 3 (2024) February request for proposals (RFP) is closed. The year 3 August RFP opens at 1 p.m. August 1, 2024.
Competitive solicitation bids for project sizes greater than 200kW up to and including 5,000kW will be accepted from 1 p.m. EPT August 1, 2024 through 1 p.m. EPT September 17, 2024.
Non-competitive bids for projects up to and including 200kW will be accepted from 1 p.m. EPT August 1, 2024 through 1 p.m. EPT September 17, 2024.
The RFP process is determined by the size of the project.
Small projects
Projects less than or equal to 200kW are awarded tariff agreements on a first-come, first-served basis at a fixed price as determined by PURA. Bids may be submitted in an online portal during the RFP window. If the cumulative capacity of small project bids submitted within the first two weeks of the RFP bid window exceeds the available MW capacity for the RFP, the small project bids submitted within the two-week window will be considered submitted at the same date/time and will be selected via a random selection process. Small project bids submitted after the two-week window will be selected on a first-come, first-served basis based on the date/time the bid is considered complete, meaning both the complete bid and the required fees (bid fee and performance assurance) have been received by the EDC.
Large projects
Projects greater than 200kW up to and including 5,000kW are awarded tariff agreements through a competitive solicitation process. Bidding will take place in an online bid portal during the RFP window.

What are Renewable Energy Certificates?
A REC is generated for each megawatt-hour (MWh) of electricity that your system generates regardless of whether you use the energy or it is exported to the electric grid.
Incentive options
Before submitting a bid, the Customer of Record must pick from two incentive compensation options: Buy-All or Netting. Each is designed to provide a similar return on investment. For current incentive rates, please see the current RFP document in the RFP Information section.
Buy-All Incentive
With the Buy-All Incentive, you will export all power that your system produces to the electric grid without first suppling power to your building.
If you choose this option:
- We will purchase power from you at a rate approved by the Public Utilities Regulatory Authority (PURA)
- You'll receive compensation as either an on-bill credit to offset your monthly bill or a cash payment once per quarter. You may specify a percentage of your compensation to be split between the two options
- You will purchase the electricity you need to power your building directly from Eversource
- Any on-bill credits not used to offset your bill can be cashed out at the end of the 20-year term
- Any cash payments can go to a third party, called a Tariff Payment Beneficiary
Meter setup
With the Buy-All Incentive, your power generation and consumption are measured using separate meters installed at your building.
Netting Incentive
With the Netting Incentive, you'll first supply power from the system to your building and only export excess power to the electric grid.
If you choose this option:
- Power produced by your system, but not consumed within the month, is "netted" at the same rate you pay Eversource for electricity
- Net credits are applied to your bill in dollars and will be used to offset future customer, supply and delivery charges
- Any excess credits can be carried over each month and cashed out if you stop electric service
- Once enrolled, your compensation rate (in dollars per kilowatt hour) for net production will fluctuate with the prevailing retail rate over a 20-year term
Meter setup
With the Netting Incentive, you’ll receive a new meter that measures how much energy you consume and how much is exported to the grid. You'll also receive a second meter to measure the energy produced by your project.
Options for State, Agricultural and Municipal customers
State, Agricultural or Municipal (SAM) customers have the opportunity to share compensation from renewable energy generation with other SAM customers. Both the Buy-All and Netting incentives are available.
SAM projects must identify the initial beneficial accounts when a bid is submitted by using the Beneficial Account Credit Allocation Form (.xls file download).
SAM Customers with the Buy-All Incentive
Just as with the standard Buy-All incentive, if you're a SAM customer who chooses the Buy-All Incentive, you'll:
- Receive compensation for all of the energy you generate
- Separately purchase the electricity you need to power your building from Eversource
As a SAM customer, you can choose to assign a percentage of your total compensation to other SAM accounts such as a public school, police department or public works department.
SAM Customers with the Netting Incentive
With this option, you net credits the same way as the standard Netting Incentive. You'll:
- First use the energy you generate with your system
- Receive credits for any excess generation (in dollars) at the same rate you pay Eversource for electricity
As a SAM customer, you can apply a percentage of your excess credits to other SAM accounts. You'll choose:
- What percentage of your excess power generation value to apply to other SAM beneficial accounts
- What percentage of your excess power generation to compensate via Renewable Energy Certificate (REC) payments

Bid calculator
Buy-All and Netting Incentive bids compete in the same competitive solicitation. Before submitting a bid, review the Guideline for bid price comparison (PDF).
You can then use the bid calculator to determine what your evaluated bid price will be and compare the Buy-All vs. Netting payment structures.
