Hei whakatutuki i te hiahia o te hiko mo te whanaketanga tauwhiro o te ohanga me te hapori o Haina, ko te State Grid Corporation o Haina, e arahina ana e te ariā pūtaiao o te whakawhanaketanga, ka whakatakoto i mua i te whainga rautaki ki te whakapakari i te raarangi whenua me te whatunga ngaohiko ultra-tiketike. te matua mai i te tirohanga o te whakapai ake i te kaha ki te arotau i te tohatoha o nga rauemi hiko o te motu me te hanga i te hapori tiaki-arotahi.Ko te raarangi hiko Uhv e tohuhia ana e te tawhiti tawhiti, te iti o te mate me te tuku kaha nui.He mea nui mo te ahumahi hiko o Haina ki te whakatutuki i nga mahi auaha motuhake, te whakapai ake i te kaha o te kaha me te whakamahi rauemi me te tautoko i te whanaketanga toiwhi o te hapori ohaoha.He kaupapa nui tenei e whakaarohia ana i runga i te ahua kore taurite o te tohatoha hiko me te whanaketanga ohaoha i Haina.

E mohio ana ko te nuinga o nga rawa kaha o Haina kei te hauauru, ko te hiahia hiko kei te rawhiti. he 500 kiromita, e tino whakatiki ana i te kaha o te tuku hiko me te tauine.Ko te tawhiti tuku o te uHV hiko hiko ka tae ki te 1,000km ki te 1,500km, ka pai ake te whakatutuki i te hiahia mo te hiko mo te whanaketanga ohaoha.I muri i te otinga o te uHV grid, te Ka whakahekehia te kaha o te hanga hiko kua whakauruhia ki te 20 miriona kilowatt, ka whakahekehia te kohi waro mo te whakaputa hiko i te 20 miriona taranata ia tau, a ko te kaha o te penapena hiko ka eke ki runga i te 100 piriona kirowatt haora ia tau. te kaha toha me te tirohanga whanaketanga whanui.
