Acushnet Ball Plant 2

Acushnet Ball Plant 2 is a 2 MW storage power plant in Massachusetts, United States of America. It is operated by Acushnet. Based on reported annual generation of -2 GWh, it can supply roughly -457 homes. It ranks #8633 of 9,833 United States of America power plants by installed capacity. Commissioned in 2019, it is around 7 years old — recently built. 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 41.7°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 26% 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: 65/100 — 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.

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.
