Johnsonville Substation - 69 kV Electrical Substation in Minnesota, USA

Johnsonville Substation is an operational electrical substation located in Minnesota, United States. Owned and operated by Redwood Electric Cooperative, this facility plays a key role in the regional electrical infrastructure. The substation operates at a voltage of 69 kV, which is typical for distribution-level substations that step down transmission voltages for local distribution. As a substation within the United States, Johnsonville Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for the bulk power system. The facility's 69 kV voltage level places it in the sub-transmission or distribution category, which is common for rural electric cooperatives serving smaller communities. The substation's environmental context includes its rural location in Minnesota, where it supports agricultural and residential electricity needs. Its role in the grid is critical for maintaining stable power supply to the surrounding area, and its operation is subject to standard environmental considerations such as electromagnetic field management and oil containment for transformers.

Johnsonville Substation is located in a rural area of Minnesota, where the surrounding landscape is primarily agricultural. The substation's operation involves standard environmental considerations for electrical infrastructure, including management of electromagnetic fields and containment of insulating oil to prevent soil and water contamination. Its rural setting reduces direct impact on densely populated areas, but it still requires adherence to environmental regulations to protect local ecosystems.
