River Valley — United States of America

Coal power plant in Oklahoma, United States of America. Approximate location 35.1931, -94.6458.

CoalOklahomaUnited States of AmericaCO₂ measured

River Valley is a 350 MW coal power station in Oklahoma, United States of America. It is operated by Oklahoma Gas & Electric Co. Based on reported annual generation of 539 GWh, it can supply roughly 154k homes. It ranks #1463 of 10,884 United States of America power plants by installed capacity. Commissioned in 1990, it is around 36 years old — long-established. Its annual emissions of 673,361 t CO₂/yr (US EPA GHGRP) are equivalent to about 157k cars driven for a year. 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).

In context: how this plant compares

At 350 MW, River Valley is below the median coal plant in United States of America (558 MW). 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.

673,361 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

3.7krailcars of coal burned
157kgasoline cars driven for a year
673kacres of US forest absorbing CO₂ for a year
0.09%of the CO₂ from all United States of America power plants with an emissions figure in PowerAtlas

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per US EPA GHGRP (measured for US EPA/EU ETS, modelled for Climate TRACE).

Local climate & thermal context

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 35.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 33% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 37/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
