Arsenal Substation - 115 kV Electrical Substation in Colorado, United States

Arsenal Substation is an operational electrical substation located in Colorado, United States. Owned and operated by Public Service Company of Colorado, it plays a key role in the regional power distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As a substation under the jurisdiction of the United States, it operates within the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The 115 kV voltage level indicates that this facility likely serves as a distribution substation, stepping down power from higher transmission voltages for local delivery. The substation's location in Colorado places it within the Western Interconnection, one of the major power grids in North America. Its operational status and connection to the Public Service Company of Colorado network contribute to the stability and reliability of electricity supply for residential, commercial, and industrial customers in the region.

The substation is situated in an urban or suburban area near Denver, Colorado, where electrical infrastructure supports a growing population and economy. The 115 kV voltage level suggests it is a distribution substation, which typically has a smaller environmental footprint than high-voltage transmission facilities. Its operation is subject to environmental regulations under the Clean Air Act and local land-use policies, though specific impacts are minimal due to the enclosed nature of substation equipment.
