To ensure fair, efficient and competitive markets, MISO requires organizations to register as Market Participants before participating in Open Access Transmission, Energy and Operating Reserve Markets.
As a Market Participant, your company becomes a legal entity certified by MISO to submit bids to purchase energy, submit offers to supply energy and operating reserve, hold financial transmission or auction revenue rights and other market-related activities.
