Raccoon Mountain
Raccoon Mountain Pumped-Storage Plant is located in southeast Tennessee on a site that overlooks the Tennessee River near Chattanooga. The plant works like a large storage battery. During periods of low demand, water is pumped from Nickajack Reservoir at the base of the mountain to the reservoir built at the top.
Types of Hydropower Plants
Small Hydropower. Although definitions vary, DOE defines small hydropower plants as projects that generate between 100 kilowatts and 10 MW. Micro Hydropower. A micro hydropower plant has a capacity of up to 100 kilowatts. A small or micro hydroelectric power system can produce enough electricity for a single home, farm, ranch, or village.

Shoalhaven Hydro proposed expansion
A: The SPHS is a "pumped hydro" power station. Water is pumped from Lake Yarrunga to Fitzroy Falls Reservoir (approximately 600 metres above the lake) and then flows back down through the two separate power stations (Bendeela and Kangaroo Valley power stations), where electricity is generated and then dispatched into the Transgrid network.
Pumped Storage
At times of low electricity demand, like at night or on weekends, excess energy is used to pump water to an upper reservoir. During periods of high electricity demand, the stored water is released through turbines in the same manner as a conventional hydro station, flowing downhill from the upper reservoir into the lower and generating electricity.
