StorageWashingtonUnited States of America
MESA 1 is a 2 MW storage power plant in Washington, United States of America. It is operated by PUD 1 of Snohomish County. Based on reported annual generation of 0 GWh, it can supply roughly -28 homes. It ranks #7957 of 9,833 United States of America power plants by installed capacity. Commissioned in 2015, it is around 11 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).

This storage plant stores and releases electricity (pumped-hydro or batteries) to balance the grid. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 47.9°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 11% 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: 55/100 — 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.
