Water is stored in a high reservoir to create potential energy due to its elevation. When the water is released and flows down to run a turbine, the potential energy is converted into kinetic energy, which turns the turbine to generate electricity. Storing water in a high reservoir allows for efficient energy production and control of electricity generation.
What else can I help you with?
What causes the turbine of a hydro-electric dam to turn?
The turbine of a hydro-electric dam turns when water from the dam's reservoir flows through it at high pressure, causing the turbine blades to spin. This spinning motion is then transferred to a generator, where it produces electricity through electromagnetic induction.
IS HYDRO ENERGY POTENTIAL OR KINETIC?
Both. Rainwater is gathered in a reservoir and held in by a dam. At that stage it has potential energy because it is high up. That energy came from the Sun that evaporated the water from the ocean. The water is then run down a chute at high speed. At that stage it has kinetic energy which is used to drive a turbine that rotates an electric generator to produce electrical energy.
What type of energy does the water have when it is in the reservior?
In a high reservoir waiting to go through a hydroelectric generator the water's main energy is potential energy because that is converted to kinetic energy before the water meets the turbine blades.
What is a Pumped Storage Reservoir?
When there is not much demand for electricity, such as during the night, the extra electricity is used to pump water back up to a storage reservoir. Then, later in the day, when electricity demand is high, the water from the storage water is also released as an extra, producing more electricity when it is needed.
What things use gravitational potential energy?
The medieval war machine the trebuchet uses gravitational potential energy to hurl rocks. Hydroelectric dams use the gravitational potential of water to convert to kinetic energy to drive a turbine and create electricity.
What is the function of the penstock?
A penstock is a pressure conduit that delivers water from a reservoir to a turbine generator in a hydropower plant. It controls the flow of water and maintains high pressure, allowing the water to generate power as it flows through the turbine.
How is the hydro energy that was collected turned into electrical energy?
The hydro energy is stored in a high reservoir before it is run down a chute to gather speed and kinetic energy, and then it hits the water turbine blades to rotate the shaft that drives the generator.

How do tunnels in dams produce electricity?
The tunnels in the dam (what you see on the "low side" of the dam) dont produce electricity. These are the 'outflow' channels for water that is exiting a turbine (which is what generates the electricity). The weight of water behind the dam forces it down a tunnel to a turbine where the water pressure spins the turbine, which generates electricity. The water, once it passes through the generator, goes out a tunnel to a river below the dam. This is typically the water you see coming out from under a "hydro-electric" dam. There are also spillways to let excess water out from the reservoir (high side) behind the dam if the water gets too high.
How does water from Delaware Reservoir get to New York?
by flying high

Why would you not heat the steam coming out of turbine and feedback to turbine?
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.

What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
How is electricity produced from burning coal or oil?
At start coal is used to burn. Then by using the heat of combustion of burning coal, stored water is heated and get converted into steam at high temperature and pressure which is further feed to turbine and on the account of rotating turbine, the generator connected to it by shaft produce electricity as per law of electromagnetic induction.
