Lawa masistimu aphatha ngempumelelo imithwalo esuka emashumini kuya ezinkulungwaneni zama-kilowatt kuwo wonke ukukhiqiza, ukunakekelwa kwezempilo, izikhungo zedatha, nezindawo zokudayisa emhlabeni wonke. Impumelelo incike ekufaniseni umthamo wesistimu wokulayisha izici, ukusebenzisa izilawuli zokuphatha amandla eziyinkimbinkimbi, nokugcina amapharamitha ashisayo nawogesi ngaphakathi kokucaciswa kwedizayini.
Njengoba ubuchwepheshe bebhethri buthuthuka-ngezindleko eziyehlayo kanye nomjikelezo wempilo owandisa-amabhethri esitoreji samandla ezentengiso azibonakalisa ngokwandayo enguzakwethu abanekhono kungqalasizinda yamandla yesimanje. Amasistimu awagcini nje ngokuphatha umthwalo; bayakwandisa, baguqule ukusetshenziswa kube izikhathi ezivumayo ngokwezomnotho kuyilapho begcina ukwethembeka okudingwa ngamabhizinisi.
