Legacy Programs


 

RSIP: Created in 2011 by the legislature to provide financial incentives to residential homeowners to install solar PV systems on their property. The program was administered by the Connecticut Green Bank (CGB). The successor program to the RSIP is the Residential Renewable Energy Solutions program authorized in the February 10, 2021 Decision in Docket No. 20-07-01, and formalized in Docket No. 21-08-02, which is in place as of January 1, 2022.

Virtual Net Metering: The VNM program allows Customers Hosts (those customers who operate behind-the-meter generation) to assign surplus production from their generator to other metered accounts, called beneficial accounts, that are not physically connected to the Customer Host’s generator. VNM credits, which are applied monthly as credits on the electric bill of the beneficial account, are equal to the generation of services charges and a declining percentage of the transmission and distribution charges (80% in the first year, 60% in year two, and 40% in year three onwards). This program is succeeded by the Non-Residential Renewable Energy Solutions program authorized in the June 30, 2021 Decision in Docket No. 20-07-01, and formalized in Docket No. 21-08-03.

LREC/ZREC: The LREC/ZREC programs required the EDCs to enter into 15-year contracts to purchase renewable energy credits (RECs) from qualifying projects in Connecticut at a fixed price for 15 years. The projects must meet the eligibility requirements, and are selected different ways, depending on the project size and generation type. These programs are also succeeded by the Non-Residential Renewable Energy Solutions program authorized in the June 30, 2021 Decision in Docket No. 20-07-01, and formalized in Docket No. 21-08-03.  To learn more about the LREC/ZREC programs, please visit the following links:

RPS (EOE): The RPS was designed to bring online renewable energy resources supporting state policy goals not otherwise being supported in the regional markets.

Each year, electric suppliers in Connecticut must comply with the RPS by procuring and properly settling the necessary amount of renewable energy certificates (RECs) to meet the percentage targets for each RPS Class, meaning they obtain the specified percentage of their retail load supplied from renewable resources within a calendar year, commonly referred to as the RPS compliance year.
