The Idylwood Substation Rearrangement Project will rebuild the existing Idylwood Substation at Shreve Road, originally built in the late 1950s, in order to support growing capacity and projected reliability concerns in the region. The proposed enhancements will provide seamless, reliable power to Fairfax County, the cities of Falls Church and Fairfax and support the energy needs of the Metrorail.
The existing Idylwood Substation at Shreve Road is situated on a 7.15 acre lot near the corner of Shreve Road and Holly Manor Drive.
Due to the limited space at the site, Dominion Energy is investing in Gas Insulated Substation (GIS) technology at the site. By utilizing GIS technology, Dominion Energy will be able to largely utilize our existing footprint while modernizing the facility to meet area demand.
