About the Registry

What is M-RETS®?

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.

 

How does M-RETS® work?

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®.

How is the M-RETS® system unique?

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.
