Membership in the Midwest ISO brings with it the ability to have a voice in the Midwest ISO committee process. A member can be a representative of one entity or may be a single membership representing several entities that share a membership and hold a single vote.

Applicants may join one of nine sectors:

• Transmission Owner
• Independent Power Producers and Exempt Wholesale Generators
• Power marketers and brokers
• Municipals, cooperatives, and transmission dependent utilities
• Public consumer advocates
• State regulatory authorities
• Environmental/other advocates
• Eligible end use customers
• Coordinating members

This sector membership will be used for representation and voting purposes on the Midwest ISO Advisory Committee. Membership also entitles applicants the ability to participate in the election of the Midwest ISO Board of Directors. An entity may opt to switch sectors on an annual basis.

To become a Midwest ISO member, a membership application must be completed. To learn more, please refer to the Membership Application page.
