Overview
Dulles Substation is an operational electrical substation in the United States, handling voltages of 230 kV, 34.5 kV, and 13.2 kV. It plays a key role in regional grid stability.
Dulles Substation is an operational electrical substation located in the United States, serving as a critical node in the regional power transmission and distribution network. The facility handles multiple voltage levels, including 230 kV for high-voltage transmission, 34.5 kV for sub-transmission, and 13.2 kV for distribution, indicating its role in stepping down power for local delivery. As part of the U.S. electrical infrastructure, Dulles Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for transmission assets, ensuring grid stability and security. The substation likely employs modern automation and protection systems compliant with industry standards such as ISO/IEC 61850 for substation automation. The substation's location in a region with significant urban and commercial development underscores its importance in maintaining reliable electricity supply. Its operational status and voltage diversity suggest it serves both industrial and residential customers, contributing to the resilience of the local grid. The facility's integration into the broader transmission network supports energy distribution across the area.
Environmental context
The substation is situated in a region with a mix of urban and suburban development, where electrical infrastructure is critical for supporting residential, commercial, and industrial activities. The voltage levels handled indicate a role in both long-distance transmission and local distribution, with potential environmental considerations related to electromagnetic fields and land use. The facility's design likely incorporates measures to minimize visual impact and ensure safe operation within the community.
