Overview
West Lemmon Substation is an operational electrical substation in the United States, owned and operated by Montana-Dakota Utilities. It handles voltages of 41600 and 4160 volts, serving the regional power grid.
West Lemmon Substation is an operational electrical substation located in the United States, owned and operated by Montana-Dakota Utilities. The facility handles primary voltage levels of 41600 volts and secondary voltage of 4160 volts, indicating a distribution-level substation that steps down transmission voltages for local distribution. Its location in the rural Great Plains region suggests it serves agricultural and small community loads. As a substation in the United States, West Lemmon Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and the Federal Energy Regulatory Commission (FERC) for interstate transmission. The facility likely includes switchgear, transformers, and protection systems compliant with IEEE standards. The voltage levels suggest it connects to subtransmission or distribution networks typical of rural utilities. The substation plays a critical role in maintaining grid stability for the region served by Montana-Dakota Utilities, a utility providing electricity to parts of Montana, North Dakota, South Dakota, and Wyoming. Its operational status ensures reliable power delivery to end-users, supporting local communities and industries. Its continued operation underscores its importance to the regional electrical infrastructure.
Environmental context
Located in the rural Great Plains of the United States, the substation's environmental context includes open grasslands and agricultural land. The area experiences a continental climate with cold winters and hot summers, which can affect equipment performance and maintenance schedules. The substation's presence supports local energy needs without significant direct environmental impact, though its operation contributes to the broader grid's environmental footprint through associated generation sources.
