Overview
Grager Substation is an operational electrical substation owned by Minnkota Power Cooperative in the United States. It operates at 115 kV, serving as a key node in the regional transmission grid.
Grager Substation is an operational electrical substation located in the United States, owned and operated by Minnkota Power Cooperative. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation within the regional transmission network. As part of Minnkota Power Cooperative's infrastructure, it supports the delivery of electricity to member cooperatives and end-users in the upper Midwest. The substation falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. The 115 kV voltage level is typical for sub-transmission and distribution substations, connecting higher-voltage transmission lines to local distribution networks. Minnkota Power Cooperative, a generation and transmission cooperative, operates a portfolio of generation assets and transmission lines, with this substation playing a role in maintaining grid stability and power flow. Grager Substation's location in the northern plains region places it in an area with significant wind energy generation and agricultural loads. The substation contributes to the reliability of the local grid, supporting both rural communities and industrial customers. Its operational status ensures continued service to the region, aligning with Minnkota's mission to provide reliable and affordable electricity to its member cooperatives.
Environmental context
The substation is situated in a rural agricultural region of the northern United States, where the grid supports both farming operations and growing renewable energy integration. The 115 kV voltage level indicates a role in distributing power from larger transmission lines to local networks, with potential environmental considerations including electromagnetic fields and land use for rights-of-way. The area's cold climate and seasonal demand peaks influence substation design and maintenance practices.
Frequently asked questions
Grager Substation is located in the United States, with coordinates approximately 46.857687 N, -96.883822 W. It is owned and operated by Minnkota Power Cooperative.
Grager Substation operates at a voltage of 115 kV, which is a common voltage level for sub-transmission and distribution substations in the United States.
Grager Substation is owned by Minnkota Power Cooperative, a generation and transmission cooperative serving member cooperatives in North Dakota and Minnesota.
Substations in the United States must comply with NERC reliability standards and FERC regulations. For 115 kV facilities, standards such as NERC CIP for cybersecurity and NERC PRC for protection systems are applicable.
A 115 kV substation typically steps down voltage from higher transmission lines (e.g., 230 kV or 345 kV) to lower distribution voltages, serving as a critical link between bulk transmission and local distribution networks.
