The Michigan Renewable Energy Certification System (MIRECS) issues, tracks and enables trading and retirement of credits through a unique, traceable serial number issued for every megawatt hour (MWh) of qualifying energy generated by facilities registered with MIRECS. The credit types include Michigan Renewable Energy Credits (RECs), Advanced Cleaner Energy Credits (ACECs) and Michigan Incentive Renewable Energy Credits (ICs). Energy Optimization Credits (EOCs) will be added at a later time. The system is set up to also support linkages with other state and regional renewable energy market programs.
