Prairie State Energy Campus is a 1,600 megawatt base load, coal-fired, electrical power station and coal mine near Marissa, Illinois southeast of St. Louis, Missouri. Prairie State Energy Campus (PSEC) features low levels of regulated emissions compared to other coal-fired power stations, capturing sulfur from high-sulfur coal mined nearby instead of transporting low-sulfur coal from elsewhere.[1][2][3]

Project

Proposed and led by Peabody Energy Corporation, the project is jointly owned by eight public electric utilities with Peabody retaining 5% ownership,[4] and is being operated by Prairie State Generating Company, LLC. The first 800 MW generator went online in June[5] and the second in November, 2012.[6] The project's Lively Grove underground mine is expected to produce 6 million tons of high sulfur coal per year.[7]

PSEC stated it will be "among the cleanest major coal-fueled plants in the nation"[8] through use of clean coal technology, producing as low as one-fifth the levels of regulated pollutants as typical U.S. coal-fired plants.[2] Noting that projected emissions nevertheless include 25,000 tons of soot and smog-forming pollutants yearly, the Sierra Club and other organizations unsuccessfully sued to stop the EPA granting an air permit.[9]

According to the Chicago Tribune, PSEC will be the "largest source of carbon dioxide built in the United States in a quarter-century."[4] The company projects a 15% reduction in carbon dioxide pollution compared with other coal-fired power plants based on its use of efficient supercritical steam generators and no emissions from transporting coal.[10]

Judging that regulatory limits on carbon emissions are not likely in the near future, Peabody chose not to employ a more expensive integrated gasification combined cycle design that could more easily be retrofitted with carbon capture technology.[11] The Environmental Protection Agency first proposed limits in March 2012. The limit of 1000 lbs CO2 emissions per megawatt-hour electricity would require future coal-powered generating stations to capture approximately half of their CO2 output. The limit would not apply to existing and under-construction generating stations, including PSEC.[12]

PSEC started delivering electricity in 2012 at prices well above market rates.[5] Some of its investors resell the energy at a loss, some raise consumer rates, and two backed out of the project.[5] PSEC's original $2 billion estimated cost attracted municipal electric utilities to invest and to sign 28 year contracts. However as of early 2010 the estimated cost had increased to $4.4 billion, requiring investors to borrow more money and raising the projected cost of electricity to undesirable levels.[4][13] Peabody in response capped construction costs at "approximately $4 billion" excluding some costs such as coal development and transmission lines.[13][14] In January 2013, with many municipalities adversely impacted by the high prices, the SEC subpoenaed information from Peabody.[15] In a bid to exit its share of the Prairie State project, the City of Hermann, MO filed a lawsuit in March, 2015 against the Missouri Joint Municipal Electric Utility Commission and the Missouri Public Energy Pool, claiming that its share of $1.5 billion in debt issued to support Prairie State imposed an unconstitutionally high level of debt on the city.[16]
