A major, multiyear project to convert Fairfax County streetlights to high-efficiency LED fixtures is nearing the finish line. The project was implemented to deliver significant energy savings, reduce greenhouse gas emissions and to ensure lighting levels to roadways meet current standards.
Dominion Energy installs, owns, operates and maintains about 96% of the 60,000 streetlights in Fairfax County. Under a coordinated plan with the county that started in 2019, the LED Conversion Program is converting more than 56,000 outdated mercury vapor, high-pressure sodium and metal halide fixtures to LEDs.
As of March 2026, approximately 93%—about 52,100 streetlights within Dominion Energy’s service area—have been upgraded to LED, with another 2,400 conversions in Dominion’s queue for estimating and construction. Combined with other streetlight conversions within the Northern Virginia Electric Cooperative (NOVEC) service area, these upgrades have reduced energy use for streetlight operations by an estimated 56 percent.
This effort is a key component of the county’s Operational Energy Strategy, which calls for lowering energy use and costs in county operations. In addition to the streetlight conversions, the county is installing LEDs in county facilities.
Overall, county government electricity consumption has declined from more than 260 million kilowatt-hours in Fiscal Year 2018 to 217 million kilowatt-hours in Fiscal Year 2025.
The Department of Public Works and Environmental Services’ Capital Facilities staff have played a key role in planning and coordinating the streetlight conversion project, working closely with Dominion Energy and other partners to ensure efficient implementation.
These upgrades help make our infrastructure more cost-effective, climate-friendly and resilient while maintaining safe and reliable lighting for residents, businesses and visitors.
