Striving to Maximize Renewable & Carbon-Free Energy

As part of MCE’s ongoing effort to deliver environmentally responsible, competitively priced retail service options, MCE routinely holds an Open Season Procurement Process. The Open Season provides a competitive, objectively administered opportunity for qualified suppliers of various energy products to fulfill MCE’s future resource requirements identified in its annual Integrated Resource Plan. In addition, MCE may issue Ad Hoc Requests for Offers (RFOs) as necessary to address specific short-term product requirements. Volumes and products requested through any Ad Hoc RFOs vary in consideration of MCE’s operational requirements.
