When it was promoting Prairie State to communities in 2007, AMP used a study by R.W. Beck, its consultant, showing that Prairie State would immediately operate at an average 85% annual capacity factor right after the plant began commercial operations, and would achieve this same excellent level of operating performance every year thereafter.
Prairie State’s 2014 operating costs were more than $13 million higher than the owners had budgeted.
The Prairie State Energy Campus failed in 2014 -- as it failed in 2012 and 2013 -- to provide the reliable, low cost power that American Municipal Power (AMP), Peabody Energy, and the other plant owners promised when they convinced more than 200 communities around the Midwest to sign long-term contracts to buy power from the plant.
