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 will replace 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 2 procurement process was developed via Public Utilities Regulatory Authority (PURA) Docket No. 22-08-03. 

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 2 (2023) request for proposals (RFP) bid schedule is as follows: 

Competitive solicitation bids for project sizes greater than 200kW up to and including 5,000kW will be accepted from February 1, 2023 through March 14, 2023. 

Non-competitive bids for projects up to and including 200kW will be accepted from February 1, 2023 through May 1, 2023. 

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. In a change from year 1 (2022), there will be no separate 2-week window during which all bids are treated as though they were submitted at the same date and time. 

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

If a project is selected, the Customer of Record will be able to pick from two incentive compensation options: Buy-All or Netting. Each is designed to provide a similar return on investment.

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 (quarterly or annually) can go to 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

Diagram showing how virtual net metering works for  state, agricultural or municipal customers that opt for the buy-all incentiveJust 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
