System and Aggregation Transfers

If you transfer ownership of your solar system when you move, or if you decide to work with a different aggregator, you or your aggregator will need to notify DOER so that we can update our records and make sure that the correct individual or aggregation receives the SRECs. If you are working with an aggregator, you should first contact them so they can handle the transfer process for you. DOER will process your request once we receive a Change Request Form and a REC Services Agreement via email at doer.srec@state.ma.us.

System Information Updates

If you need to update the equipment information or make a correction to your system information, you will also need to let us know by sending a Change Request Form to doer.srec@state.ma.us. If you are working with an aggregator, you should first contact them so they can handle the request for you.

DOER has determined that the 2018 Compliance Obligation will be 838,995 MWh and that the Minimum Standard will be 1.7903%. The details of how this Minimum Standard was determined can be found in the Determination of the CY 2018 Total Compliance Obligation and Minimum Standard

Calculation of Solar PV Capacity Factor

As required by regulation, DOER has completed its analysis of the average solar PV capacity factor for projects participating in the Solar Carve-Out. Using six years of production data from January 2010 through December 2015, DOER determined that the average capacity factor of systems operating during this period was 13.51%. This new capacity factor was used to help project the number of SRECs that will be generated in 2017 as part of the DOER’s Determination of CY2017 Total Compliance Obligation. The details of how this calculation was made can be found in the Determination of Average Solar PV Capacity Factor.

SRECs Minted and Expected

The following table was developed in an effort to provide transparency to the market in regards to the number of Solar Carve-Out Renewable Energy Certificates (SRECs) that have been minted at the NEPOOL GIS and the number of MWh that have been reported to the MassCEC Production Tracking System (PTS). The table will be updated monthly.

SRECs Minted & Expected

Minimum Standard

Each Retail Electricity Supplier, both regulated utilities and competitive suppliers, must demonstrate to DOER in an Annual Compliance Filing that it complied with the RPS Minimum Standard for the prior calendar year (Compliance Year). The Minimum Standard for the Class I Solar Carve-Out is the percentage of a Supplier's total retail load obligation that must be met by the ownership of Solar Carve-Out Renewable Energy Certificates (SRECs) issued by the NEPOOL GIS, with each SREC signifying one MWh of electrical energy from a PV Generation Unit (or Aggregation) that has been qualified by DOER for the Solar Carve-Out.

The Solar Carve-Out Minimum Standard is part of, not in addition to, the RPS Class I Minimum Standard. The Minimum Standard for the RPS Class I Solar Carve-Out of each year is calculated and announced in accordance with the provisions of the RPS Class Regulation in 225 CMR 14.07(2).

Opt-In Term

The Opt-In Term set for all projects that receive Statements of Qualification is 40 quarters or 10 years. 

Alternative Compliance Payment Rates

Competitive Retail Electric Suppliers will be able to meet their Solar Carve-Out compliance obligation for load under contract prior to January 1, 2010 with an Alternative Compliance Payment at a rate equal to the RPS Class I ACP rate for the applicable Compliance Year. These eligible contracts do not include any contracts associated with Basic Service load sold by distribution companies to retail customers. The schedule below details the ACP Rate in effect for every Compliance Year through 2025.
