Our Relentless Pursuit of Excellence

Don Gaston
President and CEO

I am pleased to report that in 2016 our team delivered strong operational performance, while driving marked improvements across our campus. Our Power Plant completed an outstanding year for safety - zero lost time injuries! Our environmental compliance was pristine. Our Mine had the lowest citation rate since inception, and achieved a federal compliance rate that is among the best in the mining industry. We set all-time monthly Plant reliability records in December, achieving 98.5 percent equivalent availability. While proud of these accomplishments and many others, we are not complacent.

Excellence at Prairie State is measured by the long-term value we provide to the 2.5 million families across the Midwest that invested in our energy campus, and we are building a company culture that will do just that.

In 2016, we continued to raise the bar in each area of our business by implementing a comprehensive strategic planning initiative with our Management Committee. This plan outlines key areas of focus for our business planning and execution for 2017 and beyond. It will lay the foundation for excellence in safety, operations, cost management, and talent readiness.


We are committed to protecting the health and safety of our teammates, and our highest priority is to achieve and sustain zero lost time incidents across the Prairie State campus. Both the Occupational Safety and Health Administration’s (OSHA) Voluntary Protection Program (VPP) Star status designation and the National Mining Association’s (NMA) CORESafety certification are recognized in their respective industries as the highest level of safety system compliance. Long-term plans to employ these best-in-class safety systems and processes at our Power Plant and Mine were initiated in 2016.

Operations & Cost Management

Operational excellence at Prairie State is best defined by Power Plant reliability and Mine efficiency. Changes made in 2016, including reduction in planned outage frequency, improvements in boiler maintenance practices, and improved mining techniques, are resulting in stronger operational performance. In each of the last two years, Prairie State’s operating expense ranked in the five best nationally in comparison with other coal facilities larger than 500 megawatts. A detailed process was established in 2016 to assure all projects provide adequate return on investment. This increased discipline is resulting in lower project cost, fewer contractors, and safer, more efficient operations.

Talent Readiness

In order to have a great company you must have great people. This year we upgraded our hiring standards and established diversity and inclusion goals. We want everyone at Prairie State to feel well-equipped to perform their job functions and empowered to share new ideas. In 2017 we will create a formal employee development process that will give the members of our team the tools to improve their skills, generate teamwork, and align with our pursuit of excellence. Each day we come to work at Prairie State we are cognizant of the unique opportunity we have to make a difference. As a company 100 percent owned by not-for-profit public power utilities and rural electric cooperatives, our success translates into growth and prosperity for the communities we serve. Electricity makes things better – it powers hospitals, businesses, homes, and schools. All of us at Prairie State are committed to excellence in our ability to continue to provide “Power from the Prairie.”

Our Vision

Our Mission

To provide value to our owners and the millions of families they serve through the safe and sustainable production of electric power.


Coal Mine and Power Plant Performance

Building on the asset preservation initiative that was established in 2015, Prairie State’s Mine continued their focus on reducing out-of-seam dilution (OSD). The Mine expanded their utilization of Smart Cut Technology, resulting in the lowest OSD to date—an 18 percent improvement over 2015. This further reduction in OSD has been directly linked to minimizing the Power Plant’s exposure to boiler erosion.

As the nation’s mining industry declines, Prairie State must maintain vigilance in its risk management processes to ensure long-term supplier stability and cost effectiveness. To that end, a thorough risk assessment study of key mine equipment and major commodity suppliers was completed in 2016. Further, through successful inventory management and stable operations, the Mine met their target for annual cost per metric ton and also reduced overall spend by $6 million.

In 2016, Prairie State’s Power Plant team worked diligently to improve operational performance for the year and to ensure the long-term viability of the asset.

In 2016, Prairie State’s Power Plant team worked diligently to improve operational performance for the year and to ensure the long-term viability of the asset. During scheduled outages on both Unit 1 and Unit 2, thorough inspections were conducted to identify necessary repairs and major causes of unavailability of the units. These scheduled outages require months of detailed planning and preparation, and resulted in improved generation results.

Several new operational milestones were achieved throughout the entire year. New records for highest monthly plant EAF (98.5%), NCF (97.4%), and net generation (1,179,112 MWh) were set in the last month of 2016. Other notable operational highlights included: longest (121 days) and third longest (99 days) runs for Unit 1, five continuous months of EAF greater than 92.8 percent for the plant, and the least number of outages for a year.
