During operation, the water level fluctuates by over 105 feet (30m) in the upper reservoir and 60 feet (20m) feet in the lower reservoir. In 1971, VEPCO did not anticipate the fracking boom that would generate a surplus of gas three decades later, ultimately causing a dramatic reduction in the price of that fuel. The overhaul of Bath County was completed within six years. The power grid will send energy into the electric generators at the station. This quickly showed that a significantly higher level of efficiency could be achieved by replacing the ventilation and cooling system as well as by redesigning the stator windings. Pumping water uphill requires more electricity than the six turbines can generate.
