    Hydroelectric power provides 24% of the world’s electricity. Plants range in power output from a few hundred kilowatts up to 10,000 megawatts. The US is world leader in HEP production.

     

    Site Requirements

    • Fast-flowing rivers or sufficient rainfall to fill reservoir.

    • Evenly distributed rainfall.

    • Suitable topography: narrow valley exit which can be dammed, giving large volume but small surface area to reduce evaporation. So, ideally, a deep, steep-sided valley.

    • Impermeable rocks/bedrock with no faults or seismic activity to prevent leakage.

    • Close to consumers/demand centre.

    • Climate that will result in a low evaporation rate.

    • Low rate of silting.

    • Site that allows easy access and construction.

    • No urban area immediately upstream as this will be a potential source of pollution/will increase treatment costs.

    • Site where construction will not cause serious damage to habitats or mean resettlement of people.
