NJ Oak Solar was constructed on a 101-acre site and connects to Atlantic City Electric’s distribution system. The project involved the removal of the dense brush and trees on site. At the time of completion, the project was the largest non-utility owned project east of the Mississippi and produced enough power to support 8,250 homes.
Ryan’s responsibilities comprised full engineering, procurement and construction of the entire system including procurement of electrical equipment, preparation of the site involving management of all project grading and trenching. Ryan also installed the support structures, module racking system, modules, inverters, DC wiring, power cables, with the associated collection equipment and all electrical systems for the entire project involving module connections and inverter installation. The Ryan team designed and optimized the project processes, installation and the 12.47kV switchyard.
