StorageAlaskaUnited States of America

Battery Energy Storage System is a 40 MW storage power plant in Alaska, United States of America. It is operated by Golden Valley Elec Assn Inc. Based on reported annual generation of -3 GWh, it can supply roughly -942 homes. It ranks #2996 of 9,833 United States of America power plants by installed capacity. Commissioned in 2004, it is around 22 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 subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 64.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 211% 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: 100/100 — 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.
