Edwardsport generating station (retired) — United States of America

Edwardsport generating station (retired) is a 109.2 MW coal power station in Indiana, United States of America. It is operated by Duke Energy Indiana LLC [100%]. Based on its capacity (estimated), it can supply roughly 137k homes (estimated). It ranks #2635 of 10,884 United States of America power plants by installed capacity. Commissioned in 1949, it is around 77 years old — an older, legacy facility. In context, coal supplies about 16.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 804 MW for Edwardsport power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Data provenance

Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.

In context: how this plant compares

At 109.2 MW, Edwardsport generating station (retired) is below the median coal plant in United States of America (558 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 38.8°N — which shapes how much energy it can produce and how its output varies through the year.

Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).

Site climate & environmental severity

This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.

How it compares & nearby plants

The #662 largest coal power plant of 802 in United States of America by capacity.
