Overview
Marvin-Corona Substation is an operational electrical substation in the United States, owned and operated by Otter Tail Power Company. It operates at 41.6 kV, serving the regional power grid.
Marvin-Corona Substation is an operational electrical substation located in the United States, owned and operated by Otter Tail Power Company. As a substation, it plays a critical role in voltage transformation and distribution within the electrical infrastructure network, connecting transmission lines to local distribution systems. The substation operates at a voltage of 41.6 kV, which is typical for sub-transmission or primary distribution levels. In the United States, such facilities are subject to NERC reliability standards and FERC regulations for grid stability. The substation's equipment likely includes switchgear, transformers, and protection systems compliant with IEEE standards. Located in a rural area of the Upper Midwest, the substation supports Otter Tail Power's service territory, which includes parts of Minnesota, South Dakota, and North Dakota. Its operational status ensures reliable electricity supply to local communities and industries, contributing to regional grid resilience.
Environmental context
The substation is situated in a rural agricultural region of the Upper Midwest, where electrical infrastructure must withstand seasonal extremes including cold winters and summer storms. The 41.6 kV voltage level indicates a distribution role, with environmental considerations focused on minimizing electromagnetic field impacts and ensuring safe operation near farmland. Vegetation management and wildlife protection are typical operational practices.
