Granite Wind Farm in New Hampshire’s Coos County is the state’s largest wind farm, powering more than 20,000 homes with 33 3MW turbines. Sertex was hired to build the collector substation and switchyard. Our scope of work on the switchyard site was all earthwork/excavation, layout, concrete foundations, fencing and ground grid. On the northern, substation site we were responsible for the same tasks as the substation yard, as well as control house installation. We completed this project ahead of schedule, even with a one-month delay. We had shift crews working seven days a week, up to 14 hours per day to complete this project.
