A $700 million natural gas pipeline enhancement project designed to improve reliability and meet rising demand came online in Wisconsin and northern Illinois at the start of the month.

TC Energy, a Canadian company with a U.S. headquarters in Texas, announced the completion of the project last month. 

The “Wisconsin Reliability Project” replaced about 51 miles of aging pipeline across Wisconsin and northern Illinois with modern infrastructure. The company said the change would improve safety and reliability.

TC Energy also upgraded natural gas compression facilities in Kewaskum and Weyauwega, as well as meter stations in Lena, Merrill, Oshkosh, South Wausau, Stevens Point, and Two Rivers. The company received approvals from federal regulators for the project in 2023 and 2024. Construction began last year, and the project came into service on November 1.
