Hydroelectric how much energy does it produce
More often than not, hydroelectric dams are used to direct the water downward through the turbine in a way which can be controlled to maximise energy production. Get a quote. The bigger the elevation and the more water that flows through the turbine, the greater the capacity for electricity generation.
This completely depends on the size of the generator and the amount of potential power available at the site. In , the UK generated around 1. Hydro can be a very predictable and consistent form of electricity which works well with other forms of renewable energy to match demand.
This means that hydro is perfect for helping meet any peak demands and balance generation throughout the day. Using hydro in combination with other more weather dependent renewable generation such as wind and solar is ideal as it can be turned on very quickly and is far more responsive than gas, coal or nuclear power stations.
Hydroelectric generators also have long lives when compared to other forms of electricity generation. A hydroelectric generator can still be in service 50 to years of working and requires very little labour with low maintenance costs which makes a lot of economic sense.

Renewable energy. Biofuels: Ethanol and Biomass-based diesel. A hydroelectric generator converts this mechanical energy into electricity. The operation of a generator is based on the principles discovered by Faraday. He found that when a magnet is moved past a conductor, it causes electricity to flow. In a large generator, electromagnets are made by circulating direct current through loops of wire wound around stacks of magnetic steel laminations.
These are called field poles, and are mounted on the perimeter of the rotor. The rotor is attached to the turbine shaft, and rotates at a fixed speed. When the rotor turns, it causes the field poles the electromagnets to move past the conductors mounted in the stator. This, in turn, causes electricity to flow and a voltage to develop at the generator output terminals. Demand for electricity is not "flat" and constant. Demand goes up and down during the day, and overnight there is less need for electricity in homes, businesses, and other facilities.
For example, here in Atlanta, Georgia at PM on a hot August weekend day, you can bet there is a huge demand for electricity to run millions of air conditioners! But, 12 hours later at AM Hydroelectric plants are more efficient at providing for peak power demands during short periods than are fossil-fuel and nuclear power plants, and one way of doing that is by using "pumped storage", which reuses the same water more than once.
Pumped storage is a method of keeping water in reserve for peak period power demands by pumping water that has already flowed through the turbines back up a storage pool above the power plant at a time when customer demand for energy is low, such as during the middle of the night.
The water is then allowed to flow back through the turbine-generators at times when demand is high and a heavy load is placed on the system. The reservoir acts much like a battery, storing power in the form of water when demands are low and producing maximum power during daily and seasonal peak periods.
An advantage of pumped storage is that hydroelectric generating units are able to start up quickly and make rapid adjustments in output. They operate efficiently when used for one hour or several hours. Because pumped storage reservoirs are relatively small, construction costs are generally low compared with conventional hydropower facilities.
