Le phrojekthi igumbi lokusabalalisa ugesi elijwayelekile, elihlanganisa ukusabalalisa kwamandla aphezulu naphansi, ukuvikelwa kombani nomhlabathi, i-alamu yomlilo nezinhlelo zokuqapha ezihlakaniphile. Ukuhlelwa okuphelele kujwayelekile futhi kuhlangabezana nezidingo zokukhiqiza kwezimboni nokusebenza okuphephile.

Lena i-substation eyakhelwe ngaphambili, enezigaba eziningi, yohlobo lwebhokisi (box-type substation) engu-35kV, eyenzelwe imetro kuphela. Lena yiyona eyisisekelo sesistimu yokusabalalisa amandla angaphandle ohlelo lokunikezwa kwamandla emetrolini. Inikeza ukusabalalisa kwamandla aphakathi nendawo (medium-voltage) okuzinzile kanye nezinsizakalo zokuguqula amavoltejji ukuze kunikezwe amandla uhlelo lokudonsa lwemetro, ukukhanyisa kwamandla nezinye izinhlelo.

Le phrojekthi ihilela ukufakwa kukatransformer omkhulu we-220kV, osisebenza njenge-"energy hub" yenethiwekhi yamandla. Unesibopho sokuguqula amandla kagesi aphezulu we-220kV abe amandla kagesi aphakathi naphansi we-110kV/35kV/10kV, futhi usetshenziswa kabanzi eziteshini ezinkulu zesifunda, ezitshalweni zamandla ezinkulu, kanye neziteshi eziyisisekelo zezimboni.

Le phrojekthi yindawo yokushaja izimoto ezisebenzisa ilanga, ehlanganisa ukukhiqizwa kwamandla elanga, ukugcinwa kwamandla, nokushaja okuhlakaniphile. Uhlobo olusha lwezinsiza zamandla aluhlaza oluhlanganisa imisebenzi eyisisekelo emithathu yokukhiqizwa kwamandla elanga, ukugcinwa kwamandla, nokushaja okuhlakaniphile. Futhi kuyisinyathelo esibalulekile sokuthuthukisa ukugcwaliswa kwezimoto ezintsha zamandla.
