Expansion Projects

According to the U.S.'s Energy Information Agency (EIA), the expansion will increase the operating pressure of the Gulfstream pipeline, to serve Tampa Electric Company's Big Bend power plant.[5] The project is a part of a larger project aimed at converting the Big Bend Power Plant from coal to natural gas.[6]

According to the U.S. Energy Information Administration, as of April 2021 the project has applied for FERC approval, which is still pending.[7]
