After years of effort, solar panels are finally coming to the I-95 Landfill Complex in Lorton.
The Fairfax County Board of Supervisors unanimously approved a motion on Sept. 13 to lease about 40 acres of the county-owned closed landfill within the complex to Sun Tribe Solar to install, operate, and maintain an array of ground-mounted solar panels.
Sun Tribe Solar, in turn, will let the county purchase renewable energy generated at the site with little upfront or operational costs, which staff say will help the county reduce its greenhouse emissions.
With the company quoting a rate of about 11 cents per kilowatt hour with no escalation over the life of the agreement, the county expects to save money immediately — about $51,000 in the first year of operation and over $1 million cumulatively by year eight.
Thought to be the first such project in the Commonwealth, the panels are expected to be installed and go online by the end of 2024, Fairfax County Department of Public Works and Environmental Services (DPWES) Deputy Director Eric Forbes said at the meeting.
As a number of supervisors noted, though, it was a long time coming, with a number of challenges along the way.
Despite solid local support, the county needed approval from the Virginia General Assembly for solar panels to be installed on its land. The county was exploring the project at least as early as 2017, but every time it was taken to the state legislature, their request was denied.
The needed permission came at last from the 2020 Solar Freedom Act, which included a specific clause providing Fairfax County the go-ahead for the landfill project.
“I really wish this had happened a long time ago when I was chair of the environment committee because that’s when we first started having this discussion,” Mason District Supervisor Penny Gross said. “[A closed landfill] is perfect for solar. If it had not been for that pesky Virginia General Assembly not allowing it unless there was a change in the legislation, we would have done this a long time ago and would have been way ahead of the game.”
Gross wasn’t the only one to express frustration at the state holding up a project that the county says will increase its use of renewable energy while also saving money. Read More
