• I-LCOC yedepho ye-1.2MW (ngesiqhelo i-$0.15-0.25/kWh) inciphisa ixabiso ledizili elilingana ne-$0.35-0.50/kWh ngexabiso elibanzi.
• Iirhafu ze-TOU kunye neenkqubo zokuphendula imfuno zivuza abaqhubi abacwangcisa iiseshoni ze-megawatt ngobulumko.
• Ubomi bebhetri buyinto efihlakeleyo: Ukutshaja kwe-2-3C kufuneka kudityaniswe nokupholisa kolwelo kunye ne-taper curves ukukhusela ubomi bepakethe.
• I-BESS buffering iguqula uxanduva lwe-demand-charge lube ngumjelo wengeniso ye-grid-services.

Qhagamshelana ne-MIDA Power iceba ikamva lokutshaja i-megawatt namhlanje — ukusuka kwiitshaja ze-DC ezikhawulezayo ezinamandla aphezulu ukuya kwiinkqubo zedepho ezidityanisiweyo ze-BESS ezenzelwe i-1.2MW nangaphezulu. Ukuze ufumane imodeli eneenkcukacha ze-LCOC, inkxaso yoyilo lwesiza, okanye ikowuteshini, nxibelelana neqela lethu. Siza kukunceda wakhe amanani ngaphambi kokuba wakhe indawo.
