Coal power plant in Ohio, United States of America. Approximate location 40.851, -81.7658.

CoalOhioUnited States of AmericaCO₂ modelled

Orrville is a 84 MW coal power plant in Ohio, United States of America. It is operated by City of Orrville - (OH). Based on reported annual generation of 15 GWh, it can supply roughly 4.2k homes. It ranks #3040 of 10,938 United States of America power plants by installed capacity. Commissioned in 1965, it is around 61 years old — an older, legacy facility. Its modelled annual emissions are 139,175 t CO₂/yr (Climate TRACE), equivalent to about 32k 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 84 MW, Orrville 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.

~139,175 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

32kpassenger cars driven for a year
18khomes' yearly energy use
2.3 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from 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 hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 40.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 35% above 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: 71/100 — this site sits in the top third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with thermal cycling the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.
