Insimbi yekhabhoni iyinhlanganisela yekhabhoni nensimbi enokuqukethwe kwekhabhoni okufika ku-2.1% ngesisindo. Ukwanda kokuqukethwe kwekhabhoni kwandisa ubulukhuni namandla ensimbi, kodwa kunciphisa ukuguquguquka. Insimbi yekhabhoni inezakhiwo ezinhle maqondana nobulukhuni namandla futhi ishibhile kunezinye izinsimbi.
Amapayipi angenamthungo ensimbi yekhabhoni asetshenziswa kabanzi ekufakweni kwe-nyukliya, ekudlulisweni kwegesi, e-petrochemical, ekwakheni imikhumbi, kuma-boiler nakwezinye izimboni, anokumelana nokugqwala okuphezulu kanye nezakhiwo ezinhle zemishini.
