MassCEC's Production Tracking System (PTS) provides renewable energy system owners a convenient method for tracking the production of their renewable energy systems as they earn Renewable Energy Certificates (RECs), while also providing industry and public stakeholders with performance data of renewable energy systems installed in the Commonwealth.

Registering a New Renewable Energy System to PTS for SREC II

If a solar PV project meets the eligibility requirements for the SREC II program, its owner or aggregator/GIS account holder may submit a Statement of Qualification Application to DOER via On-Line Registration (OLR). Once an application has been received, DOER will review the application and issue a Statement of Qualification. The system is then eligible to generate SREC at NEPOOL GIS.

MassCEC reviews the DOER-approved application for SREC II compliance. Once compliance is confirmed, MassCEC registers the system, and the system reporter can report monthly system production to the PTS to SRECs.

For more SREC information, please view the SREC II program overview, or the PTS Homeowner Guide.

Reporting Requirements for SREC Systems

All generation from qualified solar PV projects participating in the SREC market must be individually metered and production must be reported to the PTS. NEPOOL GIS Rule 2.5(j) states that only "revenue grade" (also called "revenue quality") meters tested and certified to ANSI C-12 standards are allowed to report generation data. Please reference MassCEC approved meter list (for the SREC II program).

To apply to have a new revenue grade meter added to MassCEC’ s approved meter list, please fill out the meter application and submit it to

For projects less than or equal to 10 kilowatts (kW) (DC), data can be reported manually or automatically to the PTS. For projects greater than 10 kW (DC), data must be reported automatically through a Data Acquisition System (DAS) to the PTS. A list of approved Data Acquisition System (DAS) Service Provider is available.

To learn more about automated reporting to PTS, please review the PTS automated reporting page, the PTS automated reporting guide, and the automated reporting best practices document

To apply to become an approved DAS Provider, please fill out the DAS application and submit it to

Registering a New Non-SREC Renewable Energy System to PTS

If you choose to sell your RECs for any renewable energy system, you may be required by your contract agreement with your REC owner to report production data from a revenue quality meter to the PTS.

To register a non-SREC or non-PV renewable system to the PTS, please complete the applicable form, and email to


Reporting Renewable Energy System Production to PTS

All renewable energy systems in the Commonwealth are welcome to report data to the PTS free of charge. This data must be reported during a period starting five days before the end of the month to five days after the beginning of the next month (example: January 27 – February 5). This data is analyzed on a monthly basis. System owners with erratic data may be contacted to ensure accurate data was provided and that the system is operating properly. MassCEC reserves the right to conduct on-site audits of any system to verify the accuracy of the data for SRECs. Deviations between the data and observed audited production figures may be investigated. MassCEC reserves the right to adjust or reconcile the data in accordance with the results of any audit or investigation.

For more information on reporting through the automated reporting feature in PTS, please visit the PTS automated reporting webpage.

Below are reports generated from data in the Production Tracking System:

Solar PV Systems in MA Report: A report detailing solar photovoltaic (PV) systems installed in Massachusetts that have registered for the Production Tracking System (PTS). Data includes project cost, location, panels (modules), inverters, meters and installer information.

SREC Capacity Factor Report: A report detailing the ratio between the amount of energy produced by the solar system and its optimum nameplate (labeled) production capability for systems registered for Solar Renewable Energy Certificates. The seven-year average net capacity factor for solar PV systems in Massachusetts is 13.71 percent, as of July 2017.

MassCEC has been designated by the Department of Energy Resources (DOER) as the Independent Third Party Meter Reader for the purpose of providing verification of Solar Renewable Energy Certificates (SRECs) for qualified generators. The PTS also provides MassCEC with the information necessary to monitor and evaluate the performance of renewable energy systems and the effectiveness of its renewable energy programs.
