Overview
Crow Creek Substation is an operational electrical substation in Cheyenne, Wyoming, operated by Cheyenne Light Fuel and Power/WAPA. It operates at 115 kV, serving the local grid.
Crow Creek Substation is an operational electrical substation located in Cheyenne, Wyoming, United States. It is operated by Cheyenne Light Fuel and Power in partnership with the Western Area Power Administration (WAPA), a federal power marketing administration. The substation operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission networks. The substation's 115 kV voltage level indicates its role in stepping down power from higher-voltage transmission lines for local distribution. In the United States, substations like this are subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC). The facility likely includes switchgear, transformers, and protection systems compliant with IEEE standards. Crow Creek Substation plays a key role in the electrical infrastructure of Cheyenne and the surrounding region. It supports the delivery of electricity to residential, commercial, and industrial customers, contributing to grid stability and energy reliability. The partnership between Cheyenne Light Fuel and Power and WAPA underscores the integration of federal hydropower resources into the local grid.
Environmental context
Located in Cheyenne, Wyoming, the substation operates in a semi-arid climate with cold winters and warm summers. The surrounding area is a mix of urban development and open plains. Electrical infrastructure in this region must withstand occasional severe weather, including snowstorms and high winds, which can affect grid reliability. The substation's design likely incorporates measures to mitigate environmental impacts, such as containment for insulating fluids and noise reduction.
