AES Laurel Mountain is a 97.6 MW wind farm that stretches across 12.5 miles of the western ridge of the Allegheny Mountains in north central West Virginia. The $250 million project supplies power to the market via PJM Interconnection which services thirteen states across the northeastern U.S. The site’s 61 GE 1.6 wind turbines generate an electrical capacity capable of providing energy for approximately 14,000 homes. Featured at the heart of the wind farm is a 32 MW integrated battery based energy storage system. As the world’s largest lithium-ion battery farm, Laurel Mountain is capable of storing and sending energy in short bursts and adding to the regional grid’s overall stability.
After successfully partnering on several wind farm projects in New York State, TVIG (Tennessee Valley Infrastructure Group) hired O’Connell Electric for $2.67 million to provide electrical construction and testing services for the Laurel Mountain project.
O’Connell mobilized an out-of-state workforce to satisfy a scope of work that encompassed conduit installation, high voltage terminations, and grounding. We were responsible for the conduit from each of the 61 turbine foundations to their specific pad mounted transformers, for grounding every tower, and for making high voltage terminations at the towers, transformers, termination boxes, substation, and operations and maintenance building.
O’Connell’s Technical Services Division installed all 34.5KV splices and terminations for the project. The division also performed Ground Grid Testing at each tower, testing and commissioning of each Wind Turbine Generator (WTG) Transformer, and deenergized very low frequency (VLF) testing of the complete underground collection system.
Our Communications Division executed all fiber optic terminations for SCADA communications at the site and also performed tower to tower fiber optics testing.
A single access road services Laurel Mountain Wind Farm across remote and uneven terrain. The project afforded one laydown area for temporary storage of equipment and supplies that was located six miles from the substation and six miles from the end of the line. Inclement weather forced delays for much of our work which resulted in our completing the project under heavy snow conditions. Our crews adapted to the shifting circumstances and executed all obligations within schedule and without a safety incident or injury.
