Upper Peninsula Power Company

The Upper Peninsula Power Company (UPPCO) is an electrical power utility provider headquartered in Marquette, Michigan with service centers in Escanaba, Houghton, Iron River, Ishpeming, Munising and Ontonagon.

History

The Upper Peninsula Power Company was formed in 1947 as a result of the merging of three electric utility providers: the Houghton County Electric Light Company, the Copper District Power Company, and Iron Range Light and Power.[1]

UPPCO joined a coalition led by Wisconsin Public Service Corporation (WPS) in 1961 to create a coordination of electrical service providers in Upper Michigan and Wisconsin. Through this agreement, the Wisconsin-Upper Michigan System (WUMS) was created with the ultimate goal of increasing the electrical grid resiliency by coordinating operational tasks such as equipment maintenance and construction of infrastructure facilities.[2]

In 1994, Wisconsin Public Service Corporation (WPS) formed the WPS Resources Corporation which became the holding company most partnered electric utility providers (excluding UPPCO) operated under at the time. UPPCO was eventually acquired by the holding company in 1998.[2]

In 2007, UPPCO negotiated a separation from Integrys Energy Group (the new holding company resulting from a merger between WPS Resources Corporation and Peoples Energy Corp.). The separation was effectively completed in 2017 and UPPCO resumed operation as an independent electric utility provider.

Service area

The UPPCO service area includes 10 counties in the central and western portion of Michigan's Upper Peninsula including: Alger, Delta, Marquette, Menominee, Schoolcraft, Baraga, Houghton, Iron, Ontonagon, and Keweenaw. The company serves approximately 52,000 customers which equates to approximately 12 customers per square mile.[3]

UPPCO generates approximately 20% of the electrical power distributed to its customers. Additional power is purchased from Consumers Energy in lower Michigan and the Wisconsin Energy Corporation (WE Energies). UPPCO operates multiple electrical power generation plants primarily including hydroelectric dams. Operational facilities include:
