Saldhigga Korontada Biyaha ee Matala

Saldhigga Korontada ee Matala waa saldhig koronto oo biyo-mareen ah oo ku yaalla Webiga Kunene, ee dalka Angola, kaas oo leh awood dhalineed oo la rakibay oo dhan 40 MW (54,000 hp). Saldhigga korontadu wuxuu bilaabay shaqada 1954-tii. Goobta Saldhigga korontadu wuxuu ku yaallaa bangiyada Webiga Kunene, ee magaalada Matala, ee Gobolka Huíla, ee koonfur-galbeed Angola. Matala waxay ku taallaa qiyaastii 175 kilometres (109 mi), waddo ahaan, bariga magaalada Lubango, oo ah caasimadda gobolka. Tani waa qiyaastii 985 kilometres (612 mi), waddo ahaan, koonfur-bari ee magaalada Luanda, oo ah caasimadda Angola. Taariikhda Sannadkii 1954, Biyo-xireenka Matala waxaa loo igmaday ujeedo laba geesood ah oo ah bixinta biyo loogu talagalay waraabinta gobolka iyo bixinta koronto loogu talagalay koonfur-galbeed Angola. Awooddii asalka ahayd ee lagu rakibay oo ahayd 39 megawatt waligeed lama gaarin, laakiin dayactirradii xigay ee 2001, 2011 iyo 2016 ayaa isku dayay inay gaaraan awood dhalineed oo ugu yaraan ah 40 megawatt. Tilmaamaha Biyo-xireenka Matala wuxuu leeyahay biyo-xireen (weir) cabbirkiisu ka badan yahay 700 metres (2,297 ft), oo dherer ah. Qaybaha kale ee dhismahan waxaa ka mid ah marin-galeen, marin-bax, iriddo dhaqaajin kara, qalabka farsamada korontada, khadadka korontada iyo qalabka beddelka. Biyo-xireenku wuxuu abuuraa kayd biyo ah oo leh celcelis bedka oogada oo ah 41 square kilometres (10,000 acres), oo leh awood kaydin oo dhan 60,000,000 cubic metres (2.118880003×109 cu ft). Dayactirka iyo dib-u-habeynta La aasaasay 1954, biyo-xireenka waxaa la dayactiray 2001 iyo 2011. Sannadkii 2011, Empresa Publica de Producao de Electricidade (PRODEL), oo ah mulkiilaha saldhigga korontada ayaa shaqaaleysiiyay SNC Lavalin Inc., oo ah shirkad Kanada ah si ay u "horumariso badbaadada xarunta iyo awoodda kaydinta biyaha" qiimo qandaraas oo dhan US$249.6 milyan. Dayactirka ayaa loo fuliyay wajiyo.
