Dowe Flats Substation - 115 kV Operational Substation in the United States

Dowe Flats Substation is an operational electrical substation located in the United States, with coordinates 40.221124, -105.229773. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission networks. As a substation, it serves as a critical node for stepping down voltage from transmission lines to local distribution systems, ensuring reliable electricity supply to surrounding areas. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. In the United States, substations like Dowe Flats are subject to NERC's Critical Infrastructure Protection (CIP) standards, ensuring cybersecurity and physical security. The 115 kV voltage level is commonly used for sub-transmission, connecting larger transmission networks to distribution feeders. Dowe Flats Substation contributes to the electrical infrastructure of the region by facilitating power flow and voltage regulation. Its operational status indicates ongoing service to local communities and industries. The facility's location in a rural or suburban area suggests it supports grid reliability for residential and commercial customers, with potential integration of distributed energy resources as the grid evolves.

The substation is situated in a region with varied topography and climate, which can influence electrical infrastructure operations. Voltage levels and equipment age are key factors in environmental impact; modern switchgear and insulation reduce SF6 emissions. The facility's location relative to urban or natural areas affects land use and visual impact, though substations typically have a small footprint. Grid stability and reliability are enhanced by such facilities, supporting efficient power transmission and reducing line losses.
