About the Registry
The Midwest Renewable Energy Tracking System (M-RETS®) tracks renewable energy generation and assists in verifying compliance with mandatory or voluntary State/Provincial Renewable Portfolio Standards (RPS) and objectives. M-RETS® is an important tool to keep track of all relevant information about renewable energy produced and delivered. Currently the states & provinces participating for the compliance markets are: Illinois, Iowa, Manitoba, Minnesota, Montana, North Dakota, South Dakota, Missouri, Kentucky, Arkansas, Mississippi, Louisiana, Texas and Wisconsin. M-RETS will track generation for voluntary renewable energy claims in any state or province in North America as shown below.
M-RETS® creates a renewable energy certificate for every MWh of renewable energy produced in the region, tracks the life cycle of each renewable certificate created, and ensures against any double-counting or double-use of each certificate. To learn more see Why Use M-RETS®.
M-RETS® is an easy to use, web-based system that creates, verifies, manages and enables trading for Renewable Energy Certificates (RECs). The system provides a full suite of capabilities to create unique certificates, track serial numbers, track certificates in company accounts, enable transfers and transactions, track certificate retirement, and enable compliance reporting with a full audit trail.
The Public Reports are available on the registry public reports page.
The best way is to reach out to the the Executive Director or contact the respective State Agencies and/or commissions in each participating State/Province and review their eligibility requirements. Information on each State/Provincial programs and their respective contacts can be found under the Useful Links page.

The procedure to export RECs is available in Section 15.2 of the M-RETS® Operating Procedures. If you have questions about exporting RECs from your account, please contact the M-RETS Administrator – Rosie Hoyem: systemadmin(at)mrets.org
