Fairfax County moves forward with new vendor on solar power initiative

Fairfax County is continuing its efforts to transition to renewable energy with the installation of solar panels on county government and public school buildings, but it will now do so with a different vendor.

The county ended its contract with the company Sigora Solar yesterday (July 1), about 18 months ahead of schedule.

Sigora Solar is one of three vendors awarded contracts to install, manage, and maintain solar energy infrastructure for county government and school buildings in December 2019, when Fairfax County announced what it said was the largest solar power purchase agreement initiative by a Virginia locality to date.

The original contracts with Sigora, Sun Tribe Solar, and Ipsun Power were set to run through Dec. 31, 2022.

However, the county amended its contract with Sigora on June 10 to state that it would be “terminated for convenience” effective July 1. Sigora was designated as the primary contractor for roof-mounted solar panel projects.

Moving forward, the county will now work with Sun Tribe Solar, the secondary contractor for roof-mounted panels and the primary contractor for carport or canopy-mounted panels.

“Under the terms of the agreement, the county leases space on its buildings for the companies to install solar panels that those vendors will own, and the county buys the energy generated by the panels at a fixed price,” Brian Worthy, a public information officer with Fairfax County’s Office of Public Affairs, said.

“However, these companies have the right to decide whether or not to install panels at any buildings identified by the county,” Worthy said. “During the past year and a half, the county selected 30 buildings for solar panels, and we are eager to move forward with these projects.”

The Fairfax County Board of Supervisors has approved leasing necessary roof space at two batches of county-owned properties so far. The first round of eight sites came on Oct. 20, 2020, and another 22 sites were added on March 9.

The sites approved for solar panel installations in Reston are:

• Reston Fire Station (1820 Wiehle Avenue, Reston)
• The North County Government Center (1801 Cameron Glen Dr., Reston)
• Reston Community Center Hunter Woods (2310 Colts Neck Road, Reston)
• Great Falls Volunteer Fire Station (9916 Georgetown Pike, Great Falls)

Under the solar power purchase agreements, the installed solar panels will be owned, operated and maintained by the contracted vendors, rather than the county. The county will simply purchase electricity produced by these panels over time.

When the contracts were announced in 2019, the county estimated that the initiative could potentially yield over $60 million in electricity cost avoidance over the terms of the contracts. Additionally, it was projected that approximately 1.73 million megawatt hours of renewable energy could be generated at the county’s facilities.
