Crystal Valley Substation - 115 kV Substation in Colorado, USA

Crystal Valley Substation is an operational electrical substation located in Colorado, United States, owned and operated by Core Electric Cooperative. The facility operates at a voltage level of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission networks. As a substation, it plays a critical role in stepping down voltage for local distribution and ensuring reliable power delivery to residential, commercial, and industrial customers in the region. The substation operates under the regulatory framework of the United States, which includes compliance with NERC reliability standards for grid stability and FERC oversight for interstate transmission. Core Electric Cooperative, as a member-owned utility, adheres to these standards to maintain system reliability. The 115 kV voltage level is common for sub-transmission systems that connect larger transmission lines to local distribution networks, often serving rural or suburban areas. Environmentally, the substation's location in Colorado places it within a region experiencing growing energy demand due to population growth and economic development. The facility supports grid resilience by providing voltage regulation and switching capabilities. Its operational status ensures continued service to the community, contributing to the overall stability of the regional electrical infrastructure.

The substation is situated in a semi-rural area of Colorado, where the local grid must accommodate seasonal weather variations, including winter storms and summer heat waves. The 115 kV voltage level is critical for maintaining voltage stability in the distribution network, especially as renewable energy sources like solar and wind are integrated into the regional grid. The facility's location away from dense urban centers reduces immediate environmental impact but requires robust design to withstand local climate conditions.
