This equipment was originally installed in the late 1980s on a 42-ft dam in northern Virginia. It was operated for about fifteen years, until its municipal owners decided to shut it down to preserve water levels for fire protection and recreational aesthetics of lakefront residences. After shutdown, it was left in place in the heated, well-drained powerhouse. The equipment has never been vandalized, and has no known operational problems.

The equipment was purchased by Piedmont Hydro Technologies in 2013, was removed from the powerhouse by PHT in 2013 and 2014, and transported to our yard in Mayodan, North Carolina.

All equipment is located in our yard in NC, inside or under cover, in ready to ship condition. The generator is stored with winding heat applied. The gearboxes are stored full of oil. The butterfly valves were holding back water with near zero leakage when taken out.

In addition, we'd appreciate the opportunity to quote a control system for this equipment.
