Discover What Public Power Means to Us.

The Prairie State Generating Company, LLC is a model for the future of energy. As one of the largest energy projects in the United States, Prairie State serves as an example of how legislators, regulators, public power agencies, corporations, and communities can work together to provide domestic, reliable, and environmentally friendly energy to a region.

Prairie State Generating Company

People. Power. Community.

For decades, public power utilities and rural electric cooperatives have been meeting the needs of their customers with responsible and affordable power, exceptional service, and a local focus on community initiatives. The power is quite literally in the hands of the public, as rates and generation decisions are made by members of the communities they serve.

To reliably meet growing power demands and ensure customers stable rates for the future, eight public power agencies and the world's largest coal company invested in a technologically advanced electrical generation facility and adjacent coal mine, now known as the Prairie State Energy Campus (PSEC). Since 2012, Prairie State has been providing base-load electricity on behalf of its owners to more than 2.5 million families, across 180 communities from Missouri to West Virginia.

Public power agencies are able to prepare for inevitable market changes, by hedging future risk and investing in their own sustainable generation assets. The public power investment in Prairie State is an example of progressive planning. Energy Expert and Former Director of the Illinois Power Agency, Mark Pruitt, further explains generation asset investment analysis in the October 2012 issue of Illinois Country Living Magazine.

"My Sunday school teacher used to ask ‘When did Noah build the Ark? It was before the rain.' It was hard for Noah, with years and years of effort and everyone wondering why he did it. I personally believe that electric co-ops are doing the hard work necessary in the current challenging times to prepare for the long-term best interests of their members. And I would suggest that co-op members are likely to be thankful in the future for the foresight that co-op leaders have demonstrated."

Prairie State and its employees maintain the same principles, as set forth by public power: to supply our owners with reliable power produced in a safe and environmentally responsible manner. Upholding our mission has some added benefits, including supporting the economic growth of our campus's home community in Washington County, Illinois.

In 2013, Prairie State's power plant continued on its path of progress. While the year had its operational challenges, it did yield many changes and actions that will produce important improvements in Prairie State's performance in the years to come. The power plant successfully completed its first scheduled maintenance outage in the fall on Units 1 and 2, making significant progress on increasing future reliability. Throughout the year, Prairie State's team of industry experts worked urgently and aggressively to mitigate issues as quickly as possible, while maintaining safety and compliance standards well above the industry average. Prairie State's senior leadership team members have an average of more than 30 years of diversified industry experience. Prairie State is actively developing and deploying strategies, including human error prevention tools, in order to achieve much higher reliability while driving towards a zero-accident and injury environment for all its employees.

Through February of 2014, Prairie State's power plant is exceeding its budgeted availability numbers and is focused on continued reliability improvement throughout the year. With an intense focus on our company's core values: safety, integrity, stewardship, respect, and innovation, the Prairie State Energy Campus will continue to move energy forward in communities across the Midwest for decades to come.

In 2013, Prairie State Generating Company's Coal Consumption (PSGC) power plant successfully completed its first scheduled maintenance outages on Units 1 and 2. PSGC completed the outages on schedule and on budget for planned work. During the Unit 1 scheduled maintenance outage, corrosion issues were identified and then mitigated, preventing future reliability problems, but extending the outage schedule. PSGC successfully completed the Unit 2 scheduled maintenance outage ahead of the 14 day schedule. The scheduled maintenance outages produced direct positive impact on the units' reliability, which is already showing up in 2014's first quarter results.

Continuing its path to progress, PSGC's power plant also successfully completed the shakedown period of its U.S. Environmental Protection Agency's (EPA) Clean Air Act Prevention of Significant Deterioration (PSD) of Air Quality Permit, proving to the Illinois and U.S. EPA that Unit 1 meets and in some instances, beats, its emissions limits and requirements. PSGC's Unit 2 will complete its shakedown period in May 2014.

PSGC and Bechtel Power, the construction company that built the power plant, finalized its Engineering-Procurement-Construction Agreement, drawing PSGC's construction phase to a close at the end of 2013.

PSGC believes its employees are the company's greatest asset, and the driving force for its overall success. Safety is an integral part of PSGC culture, and it continues to build upon a first-class safety and health program with an aim of making PSGC one of the safest companies and the employer of choice for the best people in the industry. In 2013, PSGC is proud to report that the power plant did not have one lost work day injury as defined by the Occupational Safety and Health Administration's (OSHA) regulations and only two recordable injuries. The power industry average for lost work day injuries is one injury per year and three recordable injuries, per 100 employees.

The coal mine also showed great success in its safety record, recording only 1.98 total recordable injuries using the Mine Safety and Health Administration's (MSHA) standards for 2013. The mining industry average for 2013 was 5.3 recordable injuries. Coal mining is a heavily regulated industry and PSGC will host, on a daily basis, federal and/or state inspectors on its premises. The mining industry average for citations is 1.5 per inspection day; PSGC's coal mine had an average of 0.56 citations per inspection day in 2013.

As PSGC closed out 2013 and focuses on its mission of "Safety. Reliability. Cost." for 2014, it is excited to demonstrate immediate improvement in the first quarter of 2014. PSGC’s current EFOR is better than planned. While the year has just begun, PSGC continues to focus on improved reliability in all aspects of its business for 2014.
