WEC Energy Group Acquisitions
WEC Energy Group has grown through strategic acquisitions that expanded its geographic footprint and customer base. The company focuses on acquiring regulated utilities with stable operations and strong cash flows.
The largest acquisition in company history occurred in June 2015 when Wisconsin Energy Corporation purchased Integrys Energy Group for $9.1 billion in cash, stock, and assumed debt. This transaction created WEC Energy Group and added Peoples Gas, North Shore Gas, Wisconsin Public Service, Michigan Gas Utilities, and Minnesota Energy Resources to the company’s portfolio. The deal made WEC Energy Group the eighth largest natural gas distribution company in the United States.
In 2000, Wisconsin Energy acquired WICOR, the holding company of Wisconsin Gas, for approximately $1.2 billion. This acquisition created the largest electric and natural gas provider in Wisconsin and positioned the company for future growth. Wisconsin Energy subsequently divested the non-energy assets of WICOR for $850 million in 2004.
WEC Energy Group acquired Bluewater Gas Storage in 2017 to strengthen its natural gas infrastructure. This Michigan-based company provides approximately one-third of the storage needs for WEC Energy Group’s natural gas distribution companies in Wisconsin. The acquisition supports reliable gas delivery during peak demand periods.
The company sold Point Beach Nuclear Plant to FPL Energy in 2007 for approximately $924 million. We Energies retained the rights to purchase the plant’s output for the life of the facility.
