History

Columbia Energy Center was built in the early 1970s. Unit 1 went online in 1975 and Unit 2 went online in 1978, with nameplate capacities of 512 MW and 511 MW, respectively.[5] [6]

In 2009, faced with environmental regulations regarding future operations, the owners of Columbia Energy Center invested in upgrades to the plant. The owners submitted an Electric Generation Expansion Analysis System (EGEAS) summary report to the Wisconsin Public Service Commission on April 2, 2009. The report presented the results of a planning and scenarios analysis to support Wisconsin Power and Light, Wisconsin Public Service Corporation, and MGE's joint application for a Certificate of Authority (CA) for the installation of emission controls at the facility.[7]

Although not required by law, the Commission held a hearing on the matter of the upgrade after several parties, including the Citizens Utility Board (CUB), Clean Wisconsin (Clean WI), and the Sierra Club, filed a joint request to intervene.

Columbia's owners were granted a Certificate authorizing the installation of air emissions reductions systems and associated equipment on March 11, 2011, at an estimate cost of $627 million.[8] Construction began on April 16, 2012 and was completed in December 2014 at a total cost of $589 million.[9]

On February 2, 2021 Alliant Energy, the majority owner and operator of the Columbia Energy Center announced the plant will shut down by 2025.[10]
