Why Solar in Coalmont Makes Sense

Tucked on the western edge of the Cumberland Plateau, Coalmont receives a surprising amount of unobstructed sunlight throughout the year. The town’s elevation, coupled with wide-open ridgelines, allows sunlight to reach rooftops for lengthy daily intervals, even during shorter winter days. This abundance of irradiance transforms Coalmont into a prime location for residential and small-commercial solar arrays.

From an electrical standpoint, distributed photovoltaic generation relieves stress on rural feeders that must stretch for miles to service spaced-out homes. By installing solar where power is consumed, voltage fluctuations are smoothed, and line losses are minimized. HEP leverages this advantage to design systems that not only offset utility bills but also improve overall grid stability in Grundy County.
