An industrial brownfield site, vacant for 35 years, is being repurposed as a productive 6-megawatt community solar project.
The 44-acre former Ciba-Geigy property in South Queensbury borders the Hudson River, nestled between Perkins Recycling and the recently shuttered Glens Falls Cement Company plant.
“With its unobstructed southern exposure, a surface-mounted solar project is the best and only practical use for the site,” Queensbury Supervisor John Strough said. “It’s the least intrusive and will add value to the property.”
The site housed several industrial plants beginning in 1901, starting with wallpaper manufacturing and later producing inorganic pigments. Hercules Inc. took over operations in 1960, selling the property to Ciba-Geigy 19 years later. Ciba-Geigy ceased operations in 1989 and demolished the buildings soon after. A more-than-decade-long cleanup effort removed toxic chemicals and heavy metals, concluding in 2002. While the topsoil at the site is now safe, contaminants remain in bedrock fissures, making excavation for large commercial developments financially unfeasible.
