2. Solar-powered pump - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_pump

   A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

3. Pumped-storage hydroelectricity - Wikipedia

   en.wikipedia.org/wiki/Pumped-storage...

   A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power.

4. Ludington Pumped Storage Power Plant - Wikipedia

   en.wikipedia.org/wiki/Ludington_Pumped_Storage...

   During periods of peak demand water is released to generate power. Electrical generation can begin within two minutes with peak electric output of 1872 MW achieved in under 30 minutes. Maximum water flow is over 33 million US gallons (120,000 m 3) per minute. This process was designed to level the load of nearby nuclear power plants on the grid.

5. Bath County Pumped Storage Station - Wikipedia

   en.wikipedia.org/wiki/Bath_County_Pumped_Storage...

   Water is released from the upper reservoir during periods of high demand and is used to generate electricity. What makes this different from other hydroelectric dams is that during times of low demand, power is taken from coal, nuclear, and other power plants and is used to pump water from the lower to the upper reservoir. Although this plant ...

6. Okinawa Yanbaru Seawater Pumped Storage Power Station

   en.wikipedia.org/wiki/Okinawa_Yanbaru_Seawater...

   Its pipelines and pump turbine were installed underground. [2] Its maximum output was approximately 2.1% of the maximum power demand in the Okinawa Island recorded on August 3, 2009. [4] The upper reservoir, artificially excavated, was approximately 600 metres (2,000 ft) away from the shoreline and approximately 150 metres (490 ft) above sea ...
