The Bath County Pumped Storage Station is a pumped storage power plant in Bath County , in the north of the State of Virginia . The hydropower plant stands at the southeast end of the Eastern Continental Divide , which at this point forms the border between Virginia and West Virginia . The power plant consists of two storage basins with a height difference of 384 m.

The power plant initially had a generator output of 2772  MW . In 2004 the performance was increased; the six generators now each have 510 MW and the pumps 480 MW. The operator puts the total output at 3,003 MW. It cost 1.6 billion dollars to build, which is equivalent to 3.8 billion dollars when adjusted for inflation. The six turbines are Francis turbines .

The ownership shares in the power plant are 60% with the operator Dominion Generation and 40% with Allegheny Power System . The power plant went into operation in 1985 and is still the most powerful of all pumped storage power plants in the world. Like all pumped storage power plants, it serves to balance the output between times with low energy demand and times with high energy demand.

During operation, the water level in the upper basin (107 ha area) fluctuates  by 32 m and in the lower basin (225 ha area) by 18 m. In generator mode, 852 m³ / s of water flow through the pipes, in pumping mode 801 m³ / s.

The dam of the lower basin is 41 m high and 732 m long, that of the upper one 140 m high and 671 m long. The lower dam consists of 3.1 million cubic meters of bulk material, the upper one of 13.8 million m³.

The natural tributaries to the reservoirs are Back Creek and Little Back Creek.
