Power plants in Louisiana fall into three broad groups: utility stations that sell electricity to the public, municipal plants run by a city or town, and industrial plants built inside refineries, chemical complexes, sugar refineries and paper mills. Our directory lists 123 of them across the state. The mix matters because each group answers to different people. Knowing which kind you are dealing with saves hours of phone calls.

Who Regulates Electric Generation in Louisiana

The Louisiana Public Service Commission (LPSC) is the main state regulator for electricity. Five commissioners, each elected from a separate district, oversee the rates and service of investor-owned utilities such as Entergy Louisiana, Cleco Power and Southwestern Electric Power Company (SWEPCO). The commission also reviews proposals to build or buy generating plants, which is why new projects often involve public hearings and written comments.

Not every plant falls under the LPSC. Entergy New Orleans is regulated by the New Orleans City Council, and municipal systems answer to their own city or town councils. Industrial plants that generate power for their own use, such as those inside chemical or paper facilities, do not set retail rates at all. They are private operations that supply the host facility.

Environmental oversight is a separate track. The Louisiana Department of Environmental Quality (LDEQ) issues air permits and monitors emissions and wastewater discharges from plants of every type. Nuclear stations also answer to the federal Nuclear Regulatory Commission, and wholesale power sales fall under the Federal Energy Regulatory Commission. Most of the state's grid is operated through the Midcontinent Independent System Operator (MISO), while parts of the northwest served by SWEPCO connect to the Southwest Power Pool.

Parishes, Not Counties: Reading the Louisiana Listings

Louisiana has parishes instead of counties, and local government works through parish councils or police juries. Our directory uses the label "County" for consistency across states, so "St. Mary County" here means St. Mary Parish. When you call a courthouse or search a government website, use the word parish.

Parish governments matter for plants because they control zoning, drainage permits and local emergency planning. If you want to know whether a facility is allowed on a particular road, start with the parish planning or permits office. State agencies handle air quality and utility rates, while the parish handles land use.

Where Louisiana's Power Plants Cluster

The Mississippi River industrial corridor

The densest concentration lies along the river between Baton Rouge and New Orleans. Iberville County lists the Plaquemine plant on West Harleaux Boulevard and Carville Energy at 4322 East Highway 30 in St. Gabriel. In Ascension County, the Basf Corp Power Plant sits at 8404 River Road in Geismar. In St. Charles County, the Shell Chemical Taft Power Plant is listed on Louisiana 3142 in Killona.

Downriver, St. Bernard County has the most listings in the state. Michoud is listed at 3601 Paris Road in Chalmette, and the American Sugar Refining Inc Power Plant is at 7417 North Peters Street in Arabi. Many of these sit inside larger industrial sites with gated access, so you will rarely find a front door marked for visitors.

Southwest Louisiana and Acadiana

Around Lake Charles, Calcasieu County includes the Citgo Petroleum Corp Power Plant at 4401 Louisiana 108 in Sulphur and Lake Charles Polymers at 4101 Louisiana 108 in Westlake. Both are tied to heavy industry. The area took a direct hit from Hurricane Laura in 2020, and plant owners here plan around storm surge and high winds.

Farther east, St. Mary County pairs the St. Mary Clean Energy Center at 272 Cabot Canal Plant Lane in Franklin with the Joseph J Cefalu Sr Municipal Steam Power Plant at 701 Avoca Road in Morgan. In Lafayette, the Louis Doc Bonin plant is listed at 1120 Walker Road. Rayne has its own listing at 801 The Boulevard.

North and central Louisiana

In the north, Ouachita Parish has the Entergy Louisiana - Sterlington Generating Power Plant at 101 Boardman Avenue. Alexandria lists D G Hunter at 1011 North 3rd Street in Rapides Parish. Several northern listings are mills or mines rather than utilities. Examples are Mansfield Mill at 1202 Louisiana 509, Westrock Hodge on Mill Street in Hodge, and Ada Carbon Solutions Red River at 201 Red River Mine Road in Coushatta. Gaylord Container's Bogalusa plant on East 4th Street serves a paper operation in Washington Parish.

Cities and small towns

In East Baton Rouge Parish County, the Entergy Gulf States Louisiana Station is listed on Gulf States Utilities Road. New Orleans lists A B Paterson at 5400 Dwyer Road. Port Allen has the La3 West Baton Rouge Solar Facility at 880 North Alexander Avenue, a reminder that not every listing burns fuel. Small towns such as New Roads, at 215 Oak Street, and Buras, at 815 Highway 11, show how local plants still serve single communities.

How to Reach the Right Contact for a Louisiana Power Plant

Most plants do not run a public counter. Safety rules, security screening and federal requirements limit who can walk in. A short sequence of steps gets you to the right person faster than showing up at the gate.

Phone numbers are limited in our database. We list 504-656-7711 for Alliance Refinery in Belle Chasse, 318-759-0170 for Ada Carbon Solutions Red River, 318-259-4421 for Westrock Hodge and 318-872-5100 for Mansfield Mill. For other entries, check the individual listing page and confirm details with the owner before you travel.

Storm season and outages in Louisiana

Hurricane season runs from June 1 to November 30, and it shapes how plants and utilities operate. After Hurricane Ida in 2021, every transmission line into New Orleans failed, and the event showed that a working plant means little if the lines are down. Report outages to your utility, never to the plant. Before you dig near a plant, a pipeline or a power line, call 811 so Louisiana One Call can mark buried utilities.

Power plant facilities in Louisiana include a mix of federal, state, and municipally owned generation assets that contribute to the region's overall electricity supply. Louisiana'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 63 cities across Louisiana. They are spread across 38 counties.

Areas with the highest concentration of power plant locations include Baton Rouge, Sterlington, Plaquemine, often reflecting proximity to water resources, fuel supply infrastructure, or industrial demand centers.

Residents of Louisiana 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.

Planning an Inquiry About a Louisiana Plant

Before you call or drive out, decide what you actually need. A resident worried about a flare, a student working on a report and a contractor seeking a bid all need different offices. Write down the plant name and street address exactly as listed, since several Louisiana plants share a parish with similar-sounding facilities.

Plants on the river corridor, such as those in Geismar, Plaquemine and Chalmette, are often next to other industrial sites. Several sit on state highways without a street number, so a GPS may drop you at the wrong gate. Call ahead and ask for the main entrance and visitor rules. Expect to show photo identification, and expect no access beyond the front office without an escort.

In north Louisiana, such as Ouachita Parish County, distances are longer and many plants sit away from town centers. Allow extra travel time, and avoid weekends when administrative staff are usually away. Keep your questions specific, and ask for the name of the person who answered, which helps if you need to follow up later.

The Louisiana Public Service Commission regulates rates for investor-owned utilities such as Entergy Louisiana, Cleco Power and SWEPCO. Entergy New Orleans is regulated by the New Orleans City Council, and municipal systems are overseen by their own governing bodies. Start by filing a complaint with your utility and keep the reference number. If the issue is not resolved, contact the LPSC consumer services staff or the council that governs your provider, and bring your account number and billing dates.

Tours are uncommon and almost always arranged in advance. Plants inside refineries and chemical complexes, such as those in Sulphur, Geismar and Killona, follow strict site security. Utility and municipal plants may host school or civic groups on request. Contact the owner's community relations office, name your group size and purpose, and ask about identification and clothing rules. Do not turn up at a gate unannounced, because staff are generally not permitted to admit visitors without prior approval.

The river offers water for cooling and steam, barge and ship access for fuel and equipment, and nearby pipelines. The stretch between Baton Rouge and New Orleans also holds many refineries, chemical plants and sugar refineries that need large amounts of steam and electricity. That demand explains why listings gather in Iberville, Ascension, St. Charles and St. Bernard parishes. Facilities in this area are also exposed to flooding and hurricane surge, so owners invest in storm planning.

Call the company that sends your electric bill. That may be Entergy, Cleco, SWEPCO, a rural electric cooperative or a city utility such as the one in Lafayette. A generating plant being nearby does not mean it serves your address, since electricity moves across the regional grid. Use the outage line or app on your bill, and report any downed lines. If you see fire, sparks or someone in danger, call 911 first and stay well away from the wires.

The Louisiana Department of Environmental Quality keeps permits, inspection reports and enforcement documents as public records. You can search them through the department's online electronic document system or submit a public records request. Have the facility name, parish and street address ready, because industrial sites often hold several permits under related names. For plants run by large industrial companies, the permit may be listed under the parent company rather than the plant name shown in our directory.

Yes. The La3 West Baton Rouge Solar Facility at 880 North Alexander Avenue in Port Allen is a solar listing. Most other entries are thermal plants powered by gas, steam or industrial fuels, and the state also has nuclear generation, including Waterford 3 in Killona. Solar sites usually have no on-site staff, so questions go to the owner or the utility that buys the output. For land-use concerns near a solar site, contact the parish government.
