AEP Bluffton NaS — United States of America

AEP Bluffton NaS is a 2 MW storage power plant in Ohio, United States of America. It is operated by Ohio Power Co. Based on its capacity (estimated), it can supply roughly 500 homes (estimated). It ranks #8758 of 10,884 United States of America power plants by installed capacity. Commissioned in 2009, it is around 17 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This storage plant stores and releases electricity (pumped-hydro or batteries) to balance the grid. 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.

Monthly mean temperature

Heating degree-days here run 34% 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

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with thermal cycling 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
