Natural gas powers homes, industries and economic growth across Wisconsin.
Demand for energy in Wisconsin is one of the fastest rising in the nation, driven by coal‑to‑gas conversions, expanding power generation and a rise in manufacturing. As the state grows, reliable natural gas supply and added pipeline capacity will be essential to keeping energy affordable, strengthening the grid, and supporting the people and industries that power Wisconsin. Pipelines are essential to keep the lights on, businesses running, and communities thriving. TC Energy has long been a cornerstone of Wisconsin’s energy supply, serving the state continuously since the establishment of the ANR Pipeline in 1945.
We operate more than 2,100 miles of pipeline in Wisconsin through our ANR Pipeline and Great Lakes Gas Transmission systems. For nearly 80 years our assets have been the backbone of Wisconsin's energy delivery network—connecting the state to secure, affordable and cleaner energy and fueling generations of industry.
Together, we’re building a stronger America from the inside out—starting right here in Wisconsin.
Wisconsin needs reliable energy. We’re helping deliver it.
Wisconsin is on track for one of the nation’s most significant natural gas demand surges—state demand is projected to grow by approximately 45% by 2035. TC Energy's infrastructure helps meet this rising demand—delivering to major local distribution companies and supporting essential and longstanding power generation.
