• Impilo yebhethri iyinguquko efihliwe: Ukushaja okungu-2-3C kumele kuhambisane nokupholisa koketshezi kanye nama-taper curve ukuze kuvikelwe isikhathi eside sephakethe.
• I-BESS buffering iguqula isibopho semali edingekayo sibe umfudlana wemali engenayo yezinsizakalo zegridi.

Xhumana ne-MIDA Power ihlela ikusasa lokushaja ama-megawatt namuhla — kusukela kumashaja asheshayo e-DC anamandla aphezulu kuya ezinhlelweni zedepho ezihlanganisiwe ze-BESS ezenzelwe i-1.2MW nangaphezulu. Ukuze uthole imodeli eningiliziwe ye-LCOC, ukwesekwa kokuklama indawo, noma ikhotheshini, xhumana nethimba lethu. Sizokusiza ukuthi wakhe izinombolo ngaphambi kokuthi wakhe indawo.
