About PTS

The Renewable Energy Production Tracking System (PTS) is a web-based application that tracks the production of renewable energy systems that are installed across Massachusetts.

It serves two primary purposes:

  • PTS provides data to the public about renewable energy systems installed in the Commonwealth to evaluate their performance, ensure the effectiveness the Commonwealth’s renewable energy programs, and to promote the growth of the industry in Massachusetts.
  • PTS provides owners of renewable energy systems a convenient method for tracking their production so that they can earn additional income by participating in certain Massachusetts clean energy incentive programs.

By verifying and reporting production data on a monthly basis, system owners – including residential owners – may sell the renewable energy production in the form of Renewable Energy Certificates (RECs) or Solar Renewable Energy Certificates (SRECs)

What is a REC?

Electricity produced by generators qualified under the Renewable Portfolio Standard (RPS) is broken into two products:

  • the electricity production that is used on-site or delivered to the grid, and
  • the positive environmental attributes associated with this clean energy production

RECs represent the second product. One REC is associated with one megawatt hour (MWh) of electricity. Retail electricity suppliers are required to purchase a certain number of RECs each year to comply with the RPS.

What is an SREC?

An SREC is a type of REC, but it is specifically designated for energy output from eligible solar photovoltaic systems, and have a significantly higher market value than other RECs. To earn SRECs, the production from your solar PV system must be reported to the PTS. Instructions and information on participating and reporting under the SREC program are detailed in the SREC Reporting Requirements.
