Owned and operated by Green Mountain Energy, this facility plays a role in the regional power distribution network, stepping down transmission-level voltages for local use. The substation operates at a voltage of 34.5 kV, which is typical for sub-transmission or primary distribution in rural and suburban areas. As part of the U.S. electrical infrastructure, it falls under the reliability standards set by the North American Electric Reliability Corporation (NERC) and is subject to Federal Energy Regulatory Commission (FERC) oversight for grid stability. Located in Vermont, Underhill Substation supports the state's electrical grid, which is increasingly integrating renewable energy sources. The facility's operational status ensures continued service to the surrounding community, contributing to the resilience and reliability of the local power supply.

Underhill Substation is situated in a rural area of Vermont, a state known for its mountainous terrain and forested landscapes. The substation's location in a region with cold winters and variable weather conditions requires robust infrastructure to maintain grid stability. The surrounding environment includes mixed forests and agricultural land, with potential impacts from ice storms and heavy snowfall that can affect overhead lines and equipment.
