CEC nke Zambia ga-akwụsị inye ọkụ na Konkola Copper Mines
Copperbelt Energy Corp (CEC) nke Zambia ga-akwụsị inye ikike na mpaghara mpaghara Vedanta Konkola Copper Mines (KCM) site na Mọnde, o kwuru mgbe mkparịta ụka gbasara ndọtị na nkwekọrịta ọkọnọ ha mebiri maka ụgwọ e ji CEC.
Mịnịsta na-ahụ maka ọkụ na Zambia Mathew Nhkuwa gwara Reuters na KCM ga-anata ikike ya ozugbo site na ụlọ ọrụ gọọmentị Zesco, nke na-erebu ọkụ eletrik nye CEC maka mbubata KCM.
Nkhuwa kwuru na nnukwu nkwekọrịta ịnye ọkụ eletrik dị n'etiti Zesco na CEC, bụ nke gwụchara na Maachị 31, agaghị emezigharị.
Nkwekọrịta ọkọnọ ike dị n'etiti CEC na KCM bịakwara na njedebe na Machị 31 wee gbasaa site na nkwekọrịta naanị ruo Mee 31, CEC kwuru na nkwupụta na Sọnde. KCM ji ụlọ ọrụ ike $132 nde, CEC kwuru.
Nkwupụta ahụ kwuru na "mkparịta ụka maka ịgbatịkwu ya emebiela, n'agbanyeghị mbọ CEC gbara n'ezi obi n'inweta nkwekọrịta ọhụrụ."
Nkwupụta nkwupụta KCM kwuru na, ka njedebe nke nkwekọrịta ya na CEC gasịrị, ụlọ ọrụ ahụ abanyela na nkwekọrịta ọzọ na Zesco, dị irè na June 1.
KCM kwuru, "Anyị na-atụ anya ngbanwe enweghị nkebi na ntinye ike sitere na CEC gaa na Zesco na nnyonye anya ma ọ bụ mmachi ọ bụla ga-abụ ihe nbibi," KCM kwuru.
N'ịgbalị ịnakwere nkwekọrịta ọhụrụ ahụ, CEC chọrọ idozi ụgwọ KCM pụtara nde $132 ma nwetakwa nkwenye siri ike n'aka KCM maka ịkwụ ụgwọ ọkụ eletrik n'oge n'ọdịnihu, o kwuru.
CEC kwuru na ya agwala KCM na a ga-akwụsị inye ya, na-agbakwunye na nke a bụ naanị nhọrọ dịnụ mgbe mkparịta ụka dara.
"Elebara anya nke ọma iji jide n'aka na usoro nke ịkwụsị inye ihe na-eme ka nchekwa nke ndị ọrụ na akụrụngwa na-echekwa iguzosi ike n'ezi ihe nke ogbunigwe," CEC kwuru.
Vedanta nke India nwere ihe dịka 80% nke KCM.
Ọ bụ ezie na Zesco ga-ebuga ike na KCM ugbu a, ọ ka ga-esi na eriri ọkụ CEC mee njem. Nkhuwa kwuru na CEC ga-emebi iwu ma ọ bụrụ na ọ jụrụ ibuba ike.
“Enyere m ngwa iwu na Fraịde, na-ekwupụta ahịrị CEC dị ka onye na-ebukarị ya. Ya mere CEC ji ụgwọ ibufe ike site na Zesco gaa KCM n'ụgwọ," Nkhuwa kwuru.
