Hydroelectric power is produced from moving water. Because the source of hydroelectric power is water, hydroelectric power plants are usually located on or near a water source. The volume of the water flow and the change in elevation (or fall) from one point to another determine the amount of available energy in moving water.
What are the benefits of using hydropower?
-
Renewable
Hydroelectric energy is renewable. This means that we cannot use up. However, there’s only a limited number of suitable reservoirs where hydroelectric power plants can be built
-
Baseload
Hydroelectricity is very reliable energy. There are very little fluctuations in terms of the electric power that is being by the plants, unless a different output is desired. Countries that have large resources of hydropower use hydroelectricity as a base load energy source. As long as there is water in the magazines electricity can be generated.
-
Domestic
Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources.
-
Fast Response Time
Some hydropower facilities can quickly go from zero power to maximum output. Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions.

-
There are a number of different hydropower technologies, but at a fundamental level, all of them produce electricity using the force of moving water, be it from waves, tides, river flows or impounded reservoirs.
-
In the future the hydropower industry will focus on projects that maximize the benefits of our existing infrastructure, such as adding new, more efficient generating equipment to existing facilities and adding electricity generating capacity to dams that have none today.
-
The “fuel” powering hydroelectric facilities is clean, renewable, zero-emission water.
