Hydro power plant in West Virginia, United States of America. Approximate location 38.1944, -81.3706.
HydroWest VirginiaUnited States of America
London is a 14 MW hydro power plant in West Virginia, United States of America. It is operated by Appalachian Power Co. Based on reported annual generation of 68 GWh, it can supply roughly 19,457 homes. It ranks #4171 of 9,833 United States of America power plants by installed capacity. Commissioned in 1936, it is around 90 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 5.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 38.2°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 8% 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: 53/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
