Wolverine Power Cooperative

What Wolverine Power Cooperative does

The cooperative generates revenue through wholesale electricity sales to its member cooperatives under long-term power supply agreements, with all margins returned to members through reduced rates—a not-for-profit model structurally eliminating external profit extraction. A complementary sub-brand, Wolverine Power Marketing Cooperative (WPMC), operates as a licensed Alternative Electric Supplier serving large commercial and industrial customers in Michigan's electric choice market via customized pricing portfolios. Wolverine has received federal funding including a New ERA (Empowering Rural America) grant and a USDA Rural Energy for America grant, and benefits from FERC-regulated transmission operations. Revenue is not publicly disclosed. Recent operational milestones include a record peak demand of 780+ MW set in June 2025 and the addition of Thumb Electric Cooperative as the cooperative's eighth member-owner in 2024.
