Pumped, Stored Reservoirs Emma Caffrey & Henry Kachadourian

In this picture the process of pumped stored reservoirs is occurring in the pumped storage power plant. This is a way of storing energy quickly when we need it. During periods of high electrical demand the stored water is released through turbines to produce electrical power. A turbine is a spinning water machine that converts kinetic energy (energy that is in motion) and potential energy of water into mechanical work. This is how it works. A way of storing energy so that we can replace it quickly when it is needed. A pumped storage plant has two separate reservoirs, an upper and lower. When electricity is in the low demand, for example at night, water is pumped into the upper reservoirs. Pumped storage plant consists of essentially of a head water pond and tail water pond. During off-peak period of the electrical grid, the water from the tail water pond is pumped back to the head water pond or reservoir. A reservoir is a large natural or artificial lake used as a source of water supply.

Pumped storage reservoirs aren't really a means of generating electrical power. They're a way of storing energy so that we can release it quickly when we need it.

Example of Pumped Stored Reservoirs in process

ADVANTAGES

An advantage of a pumped stored reservoirs is that it has little effect on the landscape

Has no pollution or waste.

Also if Power stations don’t generate more power there will cuts around the country- traffic lights will go out, causing accidents and all sort of other trouble will occur, Pumped Stored Reservoirs is a resource that generates power immediately,

It is very very fast, Nuclear power stations take much longer.

By seasonal storage through pumping, the stream flow in other rivers could be used which could otherwise run to waste. This the major advantage of pumped storage power plant.

DISADVANTAGES

once you use all the energy you cant use it again until you’ve pumped all the water back up to the top which will take a while. This is one of the most important disadvantages.

It also is very expensive to build the total cost is estimated to be $6,689,079,648

This is an example of a disadvantage of Pumped stored Reservoirs.

Renewable or Non renewable - Its not really a power station but a means of storing energy from other power stations. So the question doesn’t apply.

OTHER IMPORTANT INFORMATION

Pumped storage has been available since the 1930s

When there's a sudden demand for power, the "headgates" (huge taps) are opened, and water rushes down the tunnels to drive the turbines, which drive the powerful generators.

Pumped storage plants are unique among all the hydroelectric power plants as no flowing water supply is required. Once the head or trail pond is filled, then only inflow is required is to compensate for the evaporation and separate losses

The cost of electricity per unit during high demand (peak load demand) is much more costly than of during off-peak demands.

In Conclusion Pumped Storage Reservoirs is the most efficient for generating more power immediately with very fast results but once you use the power it take a while go back up .
