Overview
Arrowhead Substation 230/115 kV is an operational electrical substation in Minnesota, United States, owned and operated by Minnesota Power. It handles voltages of 250 kV, 230 kV, and 115 kV.
Arrowhead Substation 230/115 kV is a key electrical infrastructure facility located in Minnesota, United States. Owned and operated by Minnesota Power, the substation is part of the regional transmission grid, handling high-voltage electricity at 250 kV, 230 kV, and 115 kV. As a substation, it plays a critical role in stepping down transmission voltages for distribution or interconnecting different parts of the power system. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. Minnesota Power, a utility serving the Upper Midwest, ensures compliance with these standards to maintain grid stability. The facility's voltage levels indicate its importance in the transmission network, likely serving industrial and residential loads in the region. Located in a region with cold winters and significant industrial activity, Arrowhead Substation supports reliable electricity supply for communities and businesses. Its operational status and integration into the broader grid underscore its role in maintaining power quality and system resilience. The substation's design and technology align with typical US practices for high-voltage substations, including automation and protection systems.
Environmental context
The substation is situated in a region with a continental climate, experiencing cold winters and moderate summers. Its location in Minnesota, an area with significant forest cover and water bodies, requires careful management of vegetation and wildlife interactions to prevent outages. The facility's high-voltage equipment is designed to withstand harsh weather conditions, including snow and ice, which are common in the area. Environmental considerations include electromagnetic field management and oil containment for transformers to protect local ecosystems.
