M-RETS: Midwest Renewable Energy Tracking System

The M-RETS platform can track environmental attributes used for voluntary claims across North America.

The M-RETS Administrator will issue one electronic M-RETS Certificate for each MWh of energy that is generated by registered generators. To prevent double-counting, generators participating in M-RETS track their generation output by M-RETS.

Participation in M-RETS® is voluntary, although some states may designate the M-RETS platform as the tracking system to be used to meet a state’s renewable energy standards. Any party, including non-generators, such as traders, marketers and end-use customers may establish an account in the system.

All data in M-RETS is verified. M-RETS will not determine eligibility for state or voluntary programs. Each individual state will be responsible for determining whether a particular generating unit qualifies for a state program or not. However, the State Commissions may use the information collected and verified by M-RETS to conduct this determination. 

Eligible generation for compliance purposes may be located in:

• Arkansas
• Illinois
• Indiana
• Iowa
• Kentucky
• Louisiana
• Minnesota
• Mississippi
• Missouri
• Montana
• North Dakota
• South Dakota
• Ohio
• Texas
• Wisconsin
