Hydroelectric Power Production

WorldEconomic

The world's primary regions for producing hydroelectricity at dammed river power plants

Global Energy Observatory
The map shows the distribution of some of the world’s major hydroelectric dams and power-generating stations. In North America, these facilities are found in Canada in British Columbia, Ontario, Quebec, and Labrador. In the United States, they are on major rivers in the Pacific Northwest (for example, the Columbia River), Arizona and Utah (on the Colorado River), and in the Northeast in New York (on the Niagara River between United States and Canada) and New England. In South America, dams generate hydro power in Venezuela, Colombia, Brazil (particularly on the Paraná River and its tributaries), and in Argentina on the Rio de la Plata and on rivers that flow from the Andes mountains. In Europe, major hydroelectric facilities are found in Portugal, Norway, France, Switzerland, Ukraine (on the Dnieper River), and in Russia (on the Volga and on rivers in Siberia, which is in Asia). In Africa, these facilities have been constructed on the Nile River in Egypt, Sudan, and Ethiopia and between Zambia and Zimbabwe on the Zambesi River. In Southwest Asia, hydroelectric dams generate power on the Euphrates River in Turkey, the Tigris in Iraq, and Iran’s Zagros Mountains. In Central Asia, Tajikistan has a hydroelectric dam. In South Asia, dams have been constructed on rivers in northern Pakistan; in India on rivers in Kashmir in the north as well as in several places in central and southern India; and in Bhutan. In Southeast Asia, these facilities are found in Laos and Vietnam and in Indonesia on the islands of Java and Borneo. In East Asia, southwestern and central China have numerous hydroelectric dams, and there are also a few in northern China. Japan has a major hydroelectric dam between Tokyo and Osaka. The map does not show any hydropower production for Oceania.
