He wheketere pūtake Haina 132kw, he pai ake te whakamahi i te pēhi hau auau rerekē aukume tuturu e rua-wāhanga

1. Hangarau kōpeketanga wāhanga-rua: 15 ōrau te whakapainga i te whai huatanga pūngao, he pai ake te whai huatanga pūngao me te hiko i te kōpeketanga wāhanga-kotahi
2. mōtini tukutahi aukume tuturu: he pai ake te whai huatanga tae atu ki te 98% i ngā paerewa whai huatanga pūngao ā-motu

3.Ka whakaitihia e te pēhanga-rua-wāhanga te ōwehenga pēhanga o ia wāhanga, ka whakaitihia te turuturu o roto, ka whakapai ake i te pai o te rōrahi, ka whakaitihia te uta amo, ā, ka whakanuia ake

te oranga o te kaihautū.

4.Ka whakakapia te pēhanga kotahi-wāhanga e te PM VSD e rua-wāhanga, ā, ka piki ake te nekehanga tata ki te 15%, ka taea ai te whakatutuki i tētahi atu pānga penapena pūngao 15%.
