The Midwest Renewable Energy Tracking System (M-RETS®) tracks renewable energy generation in participating States and Provinces and assists in verifying compliance with individual state/provincial or voluntary 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 M-RETS® Tracks renewable energy in the following States: Illinois, Indiana, Iowa, Manitoba, Minnesota, Montana, North Dakota, Ohio, South Dakota, and Wisconsin. These states have policies in place requiring or strongly encouraging utility development of renewable resources. M-RETS® uses verifiable production data for all participating generators and creates a Renewable Energy Credit (REC) in the form of a tradable digital certificate for each MWh.

M-RETS® production data is provided by the Midcontinent Independent System Operator, Inc.


The M-RETS® system is administered by APX which was awarded a contract by the Public Service Commission of Wisconsin to implement, operate and administer the program.
