HydroIllinoisUnited States of America
Lockport Powerhouse is a 16 MW hydro power plant in Illinois, United States of America. It is operated by Metro Wtr Recl Dist Grtr Chi. Based on reported annual generation of 41 GWh, it can supply roughly 11,742 homes. It ranks #4053 of 9,833 United States of America power plants by installed capacity. Commissioned in 2000, it is around 26 years old — long-established. 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 hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 41.6°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 38% 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: 73/100 — this site sits in the top 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.
