A plan to build a solar farm the size of 12 football fields off Fawn Meadow Lane has been approved by the Connecticut Siting Council with a long list of conditions. Greenskies Clean Energy’s application for a certificate of environmental compatibility and public need was granted Dec. 5, clearing a required hurdle to operate a 4,625-megawatt solar array. The approval requires that Greenskies of North Haven provide a full site plan before construction on the 36-acre, heavily wooded property begins. Woodbury land use coordinator Will Agresta said Greenskies’ business model involves using the panels to generate enough electricity to power as many as 400 homes. That electricity would be harnessed and then sold to power companies. The Siting Council’s approval follows multiple hearings on the proposal last year.
