Malo opangira magetsi opangira mphamvu yamadzi momwe madzi onse kapena ambiri opangira amakhazikika ndi zosunga madzi mumtsinje.

Malo opangira magetsi opangira madzi amtundu wa madamu makamaka amatanthauza malo opangira magetsi opangira magetsi pamadzi omwe amamanga malo osungira madzi mumtsinjewo kuti apange dziwe, kuyika madzi achilengedwe kuti akweze kuchuluka kwa madzi, komanso kugwiritsa ntchito kusiyana kwamutu kupanga magetsi. Chofunikira chachikulu ndichakuti damu ndi malo opangira magetsi opangira magetsi amadzi amakhazikika mumtsinje waufupi womwewo.
Malo opangira magetsi pamadzi amtundu wa madamu nthawi zambiri amakhala ndi zosungira madzi, zotayira madzi, mapaipi oponderezedwa, makina opangira magetsi, makina opangira magetsi, ma jenereta ndi zida zina. Malo ambiri opangira magetsi opangira madzi okhala ndi madamu monga malo osungira madzi ndi malo opangira mphamvu zamagetsi apakati, ndipo malo ambiri opangira magetsi opangira madzi okhala ndi zipata popeza nyumba zosungira madzi ndi malo opangira magetsi ochepa kwambiri. Pamene mutu wamadzi suli wokwera kwambiri ndipo mtsinjewo uli waukulu, magetsi amagwiritsidwa ntchito ngati gawo losungira madzi. Malo opangira magetsi amtundu woterewa amatchedwanso malo opangira mphamvu zamagetsi pamtsinje wamtsinje, womwenso ndi malo opangira mphamvu zamagetsi ngati madamu.
Malingana ndi malo omwe pali damu komanso malo opangira magetsi amadzi, malo opangira magetsi amtundu wa madamu akhoza kugawidwa m'magulu awiri: mtundu wa madamu ndi mitsinje. Malo opangira magetsi opangira madzi amtundu wa madamu amakonzedwa kumunsi kwa madamuwo, ndipo madzi amapatutsidwa kudzera papaipi yokakamiza kuti apange magetsi. Chomeracho sichimapirira kuthamanga kwa madzi akumtunda. Nyumba yamagetsi, damu, spillway ndi nyumba zina za riverbed hydropower station zonse zimamangidwa mumtsinje. Iwo ndi mbali ya madzi kusunga dongosolo ndi kunyamula kuthamanga kwa madzi kumtunda. Kukonzekera koteroko ndi kothandiza kupulumutsa ndalama zonse za polojekitiyi.

Damu la dambo lakumbuyo kwa hydropower station nthawi zambiri limakhala lalitali. Choyamba, mutu wapamwamba umagwiritsidwa ntchito kuonjezera mphamvu yoyikapo ya malo opangira magetsi, yomwe imatha kugwirizanitsa bwino ndi zofunikira za kayendetsedwe ka mphamvu; chachiwiri, pali chosungira chachikulu chosungirako kuti chiwongolere kayendetsedwe kake kuti achepetse kuthamanga kwa madzi osefukira amtsinje wapansi; chachitatu, phindu lonse ndi lofunika kwambiri. Choyipa chake ndi chakuti kusefukira kwa madzi m'malo osungiramo madzi kumawonjezeka ndipo kusamuka ndikukhazikitsanso anthu akumidzi ndi akumidzi kumakhala kovuta. Choncho, malo opangira magetsi amadzi omwe ali kumbuyo kwa madamu omwe ali ndi madamu akuluakulu ndi malo osungiramo madzi akuluakulu amamangidwa makamaka m'zigwa zamapiri aatali, madera omwe ali ndi madzi ambiri komanso kusefukira kwamadzi.
Malo ambiri opangira magetsi akumbuyo kwa madamu omangidwa padziko lonse lapansi ali m'dziko langa. Yoyamba ndi Three Gorges Hydropower Station, yomwe ili ndi mphamvu yoyikapo ma kilowatts 22.5 miliyoni. Kuphatikiza pa zabwino zazikulu zopangira magetsi, malo opangira magetsi a Three Gorges Hydropower Station alinso ndi maubwino ambiri owonetsetsa kuti kusefukira kwa madzi pakati ndi kumunsi kwa mtsinje wa Yangtze, kukonza kayendedwe ka madzi ndi kugwiritsa ntchito madzi, ndipo kumatchedwa "zida zolemera za dziko."
