Frequently Asked Questions

  1. 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 in the region. Currently the states & provinces participating are: Illinois, Iowa, Manitoba, Minnesota, Montana, North Dakota, South Dakota, and Wisconsin.
  2. 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 About M-RETS®.
  3. Who can participate?
    There is no restriction to who may open an account in M-RETS®. However, only those renewable generators that are located in the M-RETS® footprint (or if located outside of the M-RETS® footprint, are either owned by a participating utility or have a contract with a participating utility to deliver renewable energy into the M-RETS® footprint) may be registered to an
    M-RETS® Account and subsequently have certificates created. A generating unit is considered "renewable" if the energy generated is considered renewable by any of the seven states or provinces included in the M-RETS® footprint.
  4. 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.
