For steel plants, metal fabricators, and chemical manufacturers in Klang and Pasir Gudang — the TNB Maximum Demand charge is your largest controllable cost. Our Solar + BESS systems erase MD spikes in real-time and put RM400K–RM1M back into your bottom line every year.
A 500 kWp solar array paired with 500 kWh Industrial BESS at a structural steel plant. The AI load controller predicted overhead crane and welding machine startup sequences, pre-discharging BESS to cushion the 800 kW demand spike — achieving a 22% reduction in billed Maximum Demand. Combined energy + MD savings: RM58,000/month.
Our controllers predict your load spikes and discharge solar/battery power in milliseconds to keep you below your MD threshold — every billing cycle.
Combined energy savings + MD charge reduction. GITA 60% allowance and green financing from 3.5% p.a. reduce effective payback to 2.5–3.5 years.
For a 500 kWp system at a heavy industrial plant consuming 1,600,000 kWh/year. TNB tariff escalation at 5% p.a. (conservative).

Engineering-grade systems for the most demanding industrial environments.
AI controllers predict machine startup sequences and pre-discharge BESS to flatten 30-minute demand spikes, eliminating the RM97.06/kW penalty in real-time.
Under the January 2026 Solar ATAP update, heavy industry can now install solar covering 100% of peak load — run production lines at RM0/kWh during daylight.
