Hubbard Substation - Great River Energy Electrical Substation in Minnesota

Hubbard Substation is an operational electrical substation located in Minnesota, United States. Owned by Great River Energy, a generation and transmission cooperative, the facility plays a critical role in the regional power grid. The substation handles multiple voltage levels, including 34.5 kV, 115 kV, and 230 kV, indicating its function as a transmission-level asset that interconnects different parts of the electrical network. As a substation operating under the jurisdiction of the United States, it is subject to NERC reliability standards and FERC regulation for transmission-level assets. The facility's voltage levels suggest it is a medium to high-voltage substation, typical for bulk power transmission and distribution to local utilities. Great River Energy serves member cooperatives across Minnesota and Wisconsin, making this substation an integral part of the cooperative's infrastructure. The substation's location in rural Minnesota places it within a region characterized by a mix of agricultural and renewable energy resources. It likely supports the integration of wind power, which is prevalent in the area, and ensures grid stability for surrounding communities. The operational status and ownership by a major cooperative underscore its importance in maintaining reliable electricity supply to member utilities.

The substation is situated in a rural area of Minnesota, a state with significant wind energy generation. The facility's voltage levels and role in the transmission grid make it critical for integrating renewable energy sources and maintaining grid stability. Its location away from dense urban centers reduces direct environmental impact, but its operation supports the broader environmental goal of enabling clean energy transmission.
