Jim Bridger Unit 5

From Global Energy Monitor

The existing Jim Bridger plant comprises four units, totaling 2110 megawatts (MW) of capacity. Completed in 1974, these generators use coal from the Bridger Coal and Black Butte mines. In 2006, PacifiCorp announced its intention to build a 600-800 MW expansion at the same site.[1][2]

On Jan. 18, 2007, the Oregon Public Utility Commission argued that PacifiCorp had failed to demonstrate a need for new coal-fired facilities in Wyoming and Utah. On June 7, PacifiCorp announced plans to build 1200 miles of transmission lines to connect the proposed plant to customers in three other states.[3]

On Nov. 28, 2007, PacifiCorp notified the Utah Public Service Commission that it was no longer pursuing this project, due to “the time frame and the uncertainty around coal, based on climate change issues.”[4][5]
