Glen Ullen Substation - North Dakota Electrical Substation Operated by Montana-Dakota Utilities

Glen Ullen Substation is an operational electrical substation located in North Dakota, United States. It is owned and operated by Montana-Dakota Utilities, a utility serving the region. The substation operates at a voltage level of 41.6 kV, which is typical for distribution-level infrastructure in rural areas. 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. As a distribution substation, it steps down voltage from transmission lines to serve local communities and industrial customers. The facility is part of the broader grid infrastructure in the Upper Midwest, which includes a mix of coal, natural gas, and renewable generation. Glen Ullen Substation plays a key role in maintaining grid stability and reliability for the surrounding area. Its location in a rural part of North Dakota supports agricultural and residential electricity needs. Ongoing maintenance by the operator ensures continued service.

The substation is located in a rural area of North Dakota, characterized by agricultural land and open plains. The local environment is subject to extreme weather conditions, including cold winters and occasional storms, which can affect grid reliability. The substation's 41.6 kV voltage level indicates it serves distribution needs, with lower environmental impact compared to high-voltage transmission lines.
