Ukwenza Isinqumo Sakho
Amasistimu okugcina amandla ebhethri amelela ukutshalwa kwezimali okukhulu, kodwa izindleko zehle kakhulu. Ukwehla kwentengo okungu-40%-ngaphezu{3}konyaka kwenza amaphrojekthi asebenze ngokwezimali abengeke asebenze eminyakeni emibili edlule.
Qala ngezinjongo ezicacile. Iyiphi inkinga ozama ukuyixazulula? Izinkokhelo ezifunwa kakhulu? Isikhathi esibizayo{1}se{2}}samanani okusebenzisa? Igridi engathembekile? Ikesi lakho lokusebenzisa lishayela idizayini yesistimu futhi linquma ukuthi ukutshalwa kwezimali kunengqondo.
Thola izingcaphuno eziningi. Iziphakamiso ezintathu ezivela kubadidiyeli abaqeqeshiwe zikunikeza amanani emakethe nezindlela ezihlukile zesimo sakho. Ungakhethi ngokusekelwe enanini kuphela. Linganisa ikhwalithi yobunjiniyela, ukukhethwa kwengxenye, imigomo yesiqinisekiso, nokusekelwa okuqhubekayo.
Lingisa isimo sakho esithile. Izibalo ezijwayelekile ze-ROI azibali ukwakheka kwakho kwezinga elihlukile, iphrofayili yokulayisha, kanye nezingqinamba zokusebenza. Tshala imali ekuhlaziyweni kobunjiniyela okunemininingwane ngaphambi kokuzibophezela ohlelweni lwebhethri lokugcina amandla ephrojekthi ye-BESS.
Ubuchwepheshe bukhulile. Izindleko ziyaqhubeka nokuhla. Izikhuthazi zihlala ziqinile. Uma unezindleko zikagesi eziphakeme, izindleko zokufunwa okukhulu, noma izidingo ezibalulekile zamandla, isitoreji samandla ebhethri kufanele sihlolwe kakhulu ngo-2025.
