Fairfax Connector plans to put electric buses on county roads by December

Fairfax Connector is set to start its electric bus pilot program by the end of the year.

The county-run bus service plans to introduce eight electric buses by December, according to a presentation to the Fairfax County Board of Supervisors’ transportation committee last week.

Phase one of the pilot program will run out of the West Ox bus division, which serves routes in the western and central portion of the county. Initially, electric buses will be tested on four routes. Phase two is expected to begin in 2023 and will include four additional buses on routes in the southern portion of the county.

No exact timetable was given for how long the pilot program is anticipated to last, but it will likely follow other neighboring localities and run about two years.

The hope is to transition the entire Fairfax Connector fleet to 100% zero emission buses by 2035. This deadline is based on the county’s established goal of becoming carbon neutral by 2040.

Staff identified several challenges that they will closely monitor, including ensuring there’s no reduction in service as a result of the transition. Several supervisors noted during the meeting that slower service, a reduction of routes, or constant maintenance taking buses offline could lead to fewer riders.

There are also technology limits to consider and whether the electrical grid will meet the energy requirements needed for large bus fleets.

According to the county’s Chief of Transit Dwayne Pelfrey, two thirds of current Fairfax Connector routes exceed the battery capability of electric buses. Coupled with potential issues with cold weather and hills, like Alexandria experienced late last year, electric buses may not completely meet the needs of the Fairfax Connector just yet.

That, in turn, could push potential riders back to single-occupancy vehicles, negating the emission reductions that many hope electric buses will provide.

Pelfrey also noted that obtaining buses has been increasingly difficult between supply chain issues and manufacturers not being ready to “pivot” to producing electric vehicles.

The used bus market is difficult to navigate as well, though the county did purchase 10 used buses out of North Carolina that will be transitioning to electric and 12 hybrid buses from WMATA.

Considering the county’s goals and the current price of gasoline, though, staff and board members believe the issues are worth navigating. While capital and infrastructure costs may be higher for electric buses, fuel and maintenance costs would be significantly lower over a 12-year period, according to a graph presented by staff.

The county is also exploring using hydrogen as fuel, but that technology remains expensive and more costly than electricity.

The county has already started creating infrastructure in preparation for the pilot to begin in about six months. Electric chargers arrived in April and are currently being installed, a process expected to be completed within the month.

“We are just doing simply plug-in chargers,” Pelfrey said. “When we transition full garages…we will have to do something much, much more complicated from a construction and power standpoint.”

The county’s electric buses are expected to start being manufactured late next month, received by October, and put on the road by December.

Fairfax Connector is the largest bus system in Virginia with a fleet of more than 300 buses providing nearly 18,000 rides a day.
