Wisconsin Power and Light (WPL) told the Public Service Commission of Wisconsin in a May 17 update that upgrade projects are well along at the coal-fired Columbia Energy Center.
The commission in January 2014 approved WPL, Wisconsin Public Service Corp. and Madison Gas and Electric to replace coal pulverizers and upgrade the steam turbines at the Columbia Energy Center.
The May 17 update said the Unit 2 steam turbine upgrade was placed in service on May 1, 2016. The Unit 1 turbine upgrade is currently scheduled to be placed in service in the first quarter of 2017. The replacement of the twelve pulverizers is on-going, and is projected to be completed in the third quarter of 2017.
The Columbia plant has two coal units of about 500 MW each.
