Revenue model

1. Electricity Generation and Sales: Prairie State generates electricity through its coal-fired power plant and sells baseload electricity wholesale to its nine non-profit municipal utility and cooperative owners. The campus is owned by these not-for-profit public power utilities committed to providing clean, reliable, and affordable energy for their members.

Core offering

Prairie State Energy Campus generates baseload electricity through a supercritical coal-fired power plant with two ~816 MW units (1,600 MW total) and fuels the plant from its adjacent underground Lively Grove Mine (approximately 6.5 million tons of coal annually, with over 30 years of reserves secured). Wholesale power is sold exclusively to nine not-for-profit public power ownership groups, which then distribute electricity to 2.5 million families across 180 communities in eight states.

Product overview

Prairie State Energy Campus is a mine-mouth, technologically advanced energy facility operated by Prairie State Generating Company (PSGC) in Washington County, Illinois. The campus consists of two integrated core operations: a supercritical coal-fired power plant (two 800-MW units producing 1,600 MW total) and an adjacent underground coal mine (Lively Grove Mine) that provides all fuel for the plant. The power plant uses pulverized coal technology and five emissions control technologies (Nitrogen Oxide Controls/SCR, Dry ESP, SO2 Scrubbers, Wet ESP). A $1 billion investment in Best Available Control Technology (BACT) ensures environmental compliance. The campus provides baseload electricity to 2.5 million families across 180 communities in eight states through nine non-profit public power ownership groups. Coal combustion products (gypsum, fly ash, bottom ash) are beneficially reused through dedicated programs.

Products and services

• Prairie State Energy Campus Supercritical Coal-Fired Power Plant A 1,600 MW supercritical coal-fired power plant (two ~816 MW units) that uses pulverized coal technology to generate baseload electricity for member communities across the Midwest and Mid-Atlantic.
• Lively Grove Underground Coal Mine An adjacent underground coal mine supplying approximately 6.5 million tons of coal per year to the Prairie State power plant, with over 30 years of reserves secured.
• Emissions Control Technology Systems State-of-the-art environmental control systems — including low-NOx burners, Selective Catalytic Reduction (SCR), Dry Electrostatic Precipitators, Sulfur Dioxide Scrubbers, and Wet Electrostatic Precipitators — that remove 85% of NOx, 98% of SO2, 99% of particulates, and 90% of mercury.
• Coal Combustion Products (CCP) Beneficial Reuse Program Sustainability program that beneficially reuses coal combustion byproducts, marketing gypsum as an agricultural soil amendment, fly ash as a Portland cement replacement in concrete, and bottom ash for road construction and anti-skid applications.

Direct peers

• Basin Electric Power Cooperative: Large U.S. generation-and-transmission cooperative supplying baseload power across multi-state territories, with a coal- and lignite-heavy fleet and captive member-utility offtake. Structurally the closest comparator to Prairie State: cooperative ownership, mine-mouth coal generation, mission-driven non-profit economics.
• Talen Energy Corporation: Independent power producer with a coal-heavy baseload fleet in PJM/MISO (e.g., Brunner Island, Montour) serving wholesale utility customers. Comparable in scale of supercritical coal units, MISO-adjacent operations, and reliance on wholesale power markets.
• Associated Electric Cooperative: Generation-and-transmission cooperative serving member distribution co-ops across Missouri, Iowa, and Oklahoma with substantial coal-fired baseload (New Madrid). Same cooperative-owned, captive-offtake wholesale model as Prairie State.
• Vistra Corp (Luminant): Largest U.S. independent power producer operating large supercritical coal fleets (Martin Lake, Oak Grove) as a merchant operator in ERCOT. Comparable supercritical coal technology, but merchant rather than cooperative-owned.
• Tennessee Valley Authority (TVA): Federally-owned public power generator operating large coal baseload (Cumberland, Bull Run, Kingston) serving multi-state regions through distributor customers. Closely comparable public-power, baseload, coal-heavy generation model.

Broad incumbents

• Duke Energy Corporation: Largest U.S. regulated electric utility with substantial remaining coal baseload (Cliffside, Marshall, Rogers) undergoing retirement/CCS conversions. Similar supercritical coal assets and environmental-control retrofit programs.
• Southern Company: Major regulated utility with a historically large coal fleet (Plant Bowen, Scherer) and active CCS demonstrations (Kemper post-combustion). Comparable supercritical coal technology and emissions-control retrofit strategy.
• Constellation Energy: Largest U.S. competitive generator post-Exelon spin, with material coal-heavy portfolio (Edwardsport, Keystone) operating in PJM. Comparable wholesale-merchant coal generation in adjacent power markets.
• NRG Energy: Large U.S. independent power producer with a coal-heavy commercial generation business (e.g., W.A. Parish, Limestone). Comparable supercritical coal operations, though operating in ERCOT rather than MISO.

Regional players

• Ameren Corporation: St. Louis-based regulated utility serving the same Midwest geography with significant coal baseload (Labadie, Sioux) and ongoing environmental retrofit programs. Overlaps on geography, regulatory jurisdiction, and supply chain in Washington County, Illinois.
