Indiana makes most of its electricity at large thermal stations in the southwest and the Wabash Valley. Our directory also lists hospital boiler plants, campus facilities, farm sites and newer solar parks. Each listing has a different owner and a different public contact. This page explains how these facilities are organised across Indiana, who oversees them, and how to reach the right office when you need something done.

A power plant is not a public counter like a county clerk's office. You usually cannot walk in and ask for a form. Most requests go through a utility's customer line, a state agency or a county office instead. Knowing which one applies saves hours.

Who Owns and Oversees Power Plants in Indiana

Ownership in Indiana falls into four groups. Investor-owned utilities, including Duke Energy Indiana, AES Indiana, NIPSCO, Indiana Michigan Power and CenterPoint Energy, serve most households and run many of the larger stations. Electric cooperatives are member-owned. Hoosier Energy, which operates the Merom Generating Station in Sullivan, supplies the rural electric membership corporations (REMCs) that deliver power to farms and small towns. Town-run systems, such as the Peru Electric Light & Power listing on East Canal Street, serve their own communities. The fourth group is private and institutional plants. Evonik's Tippecanoe Laboratories in Lafayette, Purdue University in West Lafayette and Hendricks Regional Health in Danville all appear in our listings.

Oversight is layered. The Indiana Utility Regulatory Commission (IURC), based in Indianapolis, regulates investor-owned utilities. Its five commissioners are appointed by the governor, and its work covers rates, service quality and approval of new utility generation. The Indiana Office of Utility Consumer Counselor (OUCC) speaks for ratepayers in those cases. Air, water and waste permits for plants come from the Indiana Department of Environmental Management (IDEM). At the federal level, the U.S. Environmental Protection Agency and the Federal Energy Regulatory Commission add rules of their own. Most of the state's grid is balanced by MISO, while some utilities in the east and north are tied to PJM.

Cooperatives and town-owned systems answer first to their own boards. For them, the right contact is often a co-op office or town hall rather than a state agency.

Coal Heritage, Gas, Wind and Solar in Indiana's Plant Listings

Indiana's grid has long leaned on coal, and the listings show it. Hoosier Energy Merom in Sullivan County, AES Petersburg in Pike County, Cayuga in Vermillion County, A B Brown on Welborn Road in Evansville and F B Culley on Darlington Road in Newburgh are all large generating sites. Several share a utility-level phone number. A B Brown and F B Culley both list 800-227-1376, which suggests calls go to the operator's central line rather than a front desk at the plant.

Names can outlast operations. Some older stations have retired units or switched fuels. A listing such as Indiana & Michigan Power Company Tanners Creek Power Plant in Lawrenceburg may describe a site that no longer generates as it once did. The Cinergy PSI listing in Connersville reflects an older corporate name, and Mirant Sugar Creek in West Terre Haute carries a former owner's brand. Treat the listed name as a way to locate the site, then confirm the current operator before you call.

Newer entries point to where Indiana is growing. Meadow Lake Wind Farm VI near Chalmers in White County belongs to a cluster of wind projects on the flat farmland of the northwest. Impa Anderson Solar Park 2 in Anderson and Impa Crawfordsville Solar Park are tied to the Indiana Municipal Power Agency, which supplies electricity to member town utilities. Oakdale in Monticello sits at the dam that creates Lake Freeman on the Tippecanoe River. The "LFGTE" in Deercroft I & II in LaPorte County signals landfill-gas-to-energy generation.

Indianapolis, the Northwest, the Wabash Valley and the Rural Counties

Indianapolis and Marion County hold the most listings. Metro listings, like Duke Building 129 at 4925 West 86th Street, are often tied to a campus or utility facility rather than a giant stand-alone station. Expect a corporate switchboard, not a plant gate.

Northwest Indiana means heavy industry. In Lake County, the Expander Turbine Power Plant at 3210 Watling Street in East Chicago and the Nipsco Dean H Mitchell Generating Station on North Clark Road in Gary sit among steel, refining and rail corridors along Lake Michigan. Lake County, like Jasper, Porter, LaPorte and Newton, observes Central time, which matters when you call.

The Wabash Valley and the southwest hold the big coal-era stations. Vigo County and its neighbours Sullivan, Vermillion, Pike and Clay lie close together, so one trip can cover several sites. Along the Ohio River, Vanderburgh, Warrick and Dearborn counties host the Evansville, Newburgh and Lawrenceburg listings.

Rural central and northwest counties are different again. Jasper County listings include Prairies Edge Generating Facility in Fair Oaks (219-394-2025) and Hidden View Dairy on Indiana 14 near Rensselaer. Farm-named listings such as Hidden View Dairy and Pastime Farm in Brazil may involve on-farm energy equipment, so ask what is actually on site. Rural addresses are often county-road coordinates, such as 4078 West County Road 900 North for Pastime Farm. Check the route and call ahead before driving out.

Practical Steps Before You Contact an Indiana Power Plant

A few habits make the process smoother for tours, permit questions and business contacts.

If you are unsure who runs a site, start with the county where it sits. The county's plan commission, assessor or emergency management office can usually tell you the current owner. The IURC can confirm whether a utility is regulated.

Power plant facilities in Indiana include a mix of federal, state, and municipally owned generation assets that contribute to the region's overall electricity supply. Indiana's energy mix and the number of publicly owned facilities reflect the state's natural resources, regulatory environment, and historical development of its utility infrastructure.

Power Plant locations are available in 93 cities across Indiana. They are spread across 60 counties.

Areas with the highest concentration of power plant locations include Indianapolis, Evansville, East Chicago, often reflecting proximity to water resources, fuel supply infrastructure, or industrial demand centers.

Residents of Indiana who are customers of a municipal or public power utility can contact their local power authority for billing assistance, energy efficiency programs, and information about planned outages or infrastructure upgrades in their service area.

Residents of Indiana who receive electricity service from a publicly owned utility can visit or contact that utility's customer service office to learn about outage reporting, billing options, and energy assistance programs. For information about a specific power generation facility in Indiana, contacting the state's public utility commission is often the best starting point.

Finding Permits, Rate Cases and Local Rules for Indiana Plants

Public records on Indiana power plants sit in several places, and none of them is the plant itself. Environmental permits, inspection reports and compliance letters are filed with the Indiana Department of Environmental Management, which publishes many of them through its online Virtual File Cabinet. Rate cases, service complaints and plans for new utility generation are handled by the Indiana Utility Regulatory Commission, whose case files are open to the public. Building, zoning and land-use rules come from the county or town where the plant stands.

That split matters in practice. A neighbour worried about noise from a plant in East Chicago or Gary starts with city or county officials and IDEM. A customer disputing a bill from a regulated utility starts with the utility, then the IURC's consumer affairs staff. A landowner approached about a solar lease near Anderson or Crawfordsville should read the local zoning ordinance and ask the plan commission which approvals apply.

Emergencies follow a simpler rule. Call 911 first for fire, injury or a downed line. Each Indiana county also has an emergency management agency that works with local responders, so it is the right office for questions about alerts and evacuation planning near a large station such as Petersburg or Merom.

Indiana Power Plant Questions Answered

Three bodies matter most. The Indiana Utility Regulatory Commission regulates investor-owned electric utilities, including their rates, service standards and applications to build or retire generation. The Office of Utility Consumer Counselor represents ratepayers in those proceedings. The Indiana Department of Environmental Management issues and enforces air, water and waste permits for plants, including emissions and coal ash rules. Federal agencies, mainly the EPA and FERC, sit above them. Cooperatives and town-owned systems have their own boards, so a complaint about one of those often starts locally.

Tours are the exception, not the rule. Large stations such as Merom, Petersburg and Cayuga are secure industrial sites, and most do not accept drop-in visitors. Call the main number and ask for community relations or public affairs. If you represent a school or club, ask several weeks ahead. Expect to show photo ID, sign in and wear provided safety gear. Campus plants, such as Purdue's in Tippecanoe County, and hospital plants are usually reached through the facilities department. Some operators offer presentations in place of plant-floor visits.

Call your utility, not the plant. Your bill shows whether you are served by an investor-owned utility, a REMC or a municipal system, and each runs its own outage line. Plant listings such as A B Brown in Evansville or F B Culley in Newburgh, both in the Vanderburgh County area of the Ohio River corridor, will not take outage reports. If a line is sparking or lying across a road, call 911. Before any digging, even for a fence post, call 811 so underground lines are marked. The service is free.

Indiana's generating fleet has changed hands many times through mergers, sales and rebranding. PSI Energy, part of Cinergy, became Duke Energy Indiana after Duke acquired Cinergy, but older records and signs still carry the earlier names. Mirant Sugar Creek in West Terre Haute likewise reflects a former owner. Use the listed name and address to find the site, then check the current operator through the utility's website, an IDEM permit record or the county assessor before you contact anyone.

Local government handles the land-use side. A developer typically needs zoning approval from the county or town plan commission, and many counties have wind or solar ordinances setting setbacks, noise limits and decommissioning terms. Utility-owned projects may also need IURC approval, and construction can require IDEM stormwater permits. If a developer approaches you in White or Jasper County about a lease or easement, read the county ordinance first, ask for the contract in writing and consider having an attorney review it.

White plumes from tall cooling towers are usually water vapor, and they are most visible on cold Indiana mornings. Dark smoke, a strong chemical odor, unusual noise or flaring is different. For fire, injury or immediate danger, call 911. For non-urgent concerns, call the plant's main number first, because operators can often explain a start-up, test or maintenance event. If the answer does not satisfy you, file a complaint with IDEM. Your county emergency management agency can answer questions about local alerts and emergency plans.
