Imboni yokuphehla ugesi idinga amabhokisi kagesi afakwa kanzima futhi asebenzayo ukubhekana nezidingo zempahla eningi. Siletha amathuluzi imboni edinga ukugcina amadrayivu abo okuhambisa kanye ne-stacker enza kahle kakhulu. Izici ezibalulekile njengokusebenza kahle kwe-thermal, ukukhweza nokufaka uphawu amasistimu enzelwe ukuqinisekisa ukusebenza okuphezulu ezinhlelweni zokukhiqiza amandla.
Izinhlelo zamaGiya zifakazelwa ukuthi ziyamelana nezimo ezinzima zokugaya futhi zenzelwe ukucacisa izidingo zamakhasimende ukuqinisekisa ukusebenza okuphezulu.
