Overview
Eagle River is an operational electrical substation in Wisconsin, United States, operating at 115 kV. It plays a role in regional grid stability and power distribution.
Eagle River is an operational electrical substation located in Wisconsin, United States. With a voltage level of 115 kV, it is classified as a transmission-level substation, serving as a critical node in the regional power grid. The facility is part of the broader North American electrical infrastructure, which is regulated by NERC reliability standards and FERC oversight. The substation operates under the regulatory framework of the United States, where transmission assets must comply with NERC's Critical Infrastructure Protection (CIP) standards and FERC's tariff requirements. At 115 kV, Eagle River is typical of medium-voltage substations that interconnect local distribution networks with higher-voltage transmission lines. Such facilities often utilize air-insulated or gas-insulated switchgear, depending on age and environmental conditions. Eagle River's location in northern Wisconsin places it in a region with significant seasonal demand variations, from winter heating to summer cooling. The substation supports local communities and industries by ensuring reliable power delivery. Its operational status contributes to grid resilience, particularly in areas prone to extreme weather events common in the Great Lakes region.
Environmental context
The substation is situated in a forested region of northern Wisconsin, an area characterized by cold winters and moderate summers. The local environment includes mixed hardwood forests and numerous lakes, which can influence infrastructure maintenance and vegetation management. The 115 kV voltage level suggests the substation serves both rural and semi-urban loads, with potential impacts on local wildlife corridors and land use.
Frequently asked questions
The Eagle River substation is located in Wisconsin, United States, near the city of Eagle River. Its approximate coordinates are 45.910318, -89.258363.
The Eagle River substation operates at 115 kV, which is a common voltage level for transmission substations in the United States.
As part of the U.S. electrical grid, the Eagle River substation is subject to NERC reliability standards and FERC regulation for transmission-level assets.
A 115 kV substation typically steps down voltage from higher transmission lines (e.g., 230 kV or 345 kV) for distribution to local networks, or interconnects generation sources. It is critical for grid stability and load balancing.
Substations in Wisconsin must manage vegetation growth to prevent outages, especially in forested areas. They also need to withstand winter weather conditions, including ice and snow accumulation on equipment.
