An agreement to buy the full output of a 20-megawatt solar project planned for construction in southeast Georgia will increase Green Power EMC's ability to deliver electricity from renewable sources by more than 60 percent. Planters Electric Membership Corp., based in Millen, and Canoochee EMC, which has offices in Reidsville, Hinesville and Pembroke, are participants in the project. Silicon Ranch Corp., based in Nashville, Tenn., will build and own the ground-based solar array, which will occupy 135 acres near Hazlehurst in Jeff Davis County with more than 87,000 solar modules.
