The Fengning Pumped Storage Power Station, the world''s largest facility of its kind, has commenced full operations with the commissioning of its final variable-speed unit on December 31. Located in
The pumped storage power station consists of two circular concrete silos, each of about 32 metres (105 ft) internal diameter. Each of the silos houses a 250 megawatts (340,000 hp) turbine generator and pump set, giving a total capacity of 500 megawatts (670,000 hp).
Pumped storage power plants are used to balance the frequency, voltage and power demands within the electrical grid; they are often utilized to add additional megawatt capacity to the grid during periods of high power demand. For this reason, pumped storage plants are referred to as ‘ peaking ’ plants. Electrical Grid Power Demand Graph
Pumped storage plants convert potential energy to electrical energy, or, electrical energy to potential energy. They achieve this by allowing water to flow from a high elevation to a lower elevation, or, by pumping water from a low elevation to a higher elevation. When water flows to a lower elevation, the power plant generates electricity.
Electrical Grid Power Demand Graph Because pumped storage plants can provide electrical grid operators with power ‘on-demand’, they have a high level of dispatchability (the ability to provide power to the grid quickly when needed). Irrespective geographical location, all pumped storage plants require an upper reservoir and lower reservoir.
Power is purchased from the grid at 1ct/kWh to pump water from the lower to upper reservoir. Power is sold to the grid at 2ct/kWh by allowing water to flow from the upper to lower reservoir. The pumped storage plant has generated 1ct/kWh of profit during this process because: 2ct/kWh (sale) - 1ct/kWh (purchase) = 1ctkWh (profit).
Water is pumped from the lower reservoir to the upper reservoir by the Francis turbine runner. The flow path is the same as when generating electricity, except the flow direction is reversed because the Francis runner is used as a pump instead of a turbine. Pumped storage plants rely upon the varying price of electricity to make a profit.
