Get QuoteTNB Bill Audit
Malaysian businesses leak millions yearly on wrong TNB tariff class, ICPT miscalculation, and maximum demand penalties. Our AI-powered audit finds the leaks and recovers up to 6 months of refunds. RM800–RM5,000 flat fee — paid only on findings.
What we audit
Six categories where TNB billing errors concentrate — most SMEs have at least two active issues they are unaware of.
Tariff Class (C1 / C2 / D / E)
Most SMEs are on the wrong tariff — placed on C2 when C1 applies, or D when the load profile fits E. Each misclassification adds 8–22% to your monthly bill. We check your registered tariff against your actual contracted capacity and consumption pattern.
ICPT Surcharge
The Imbalance Cost Pass-Through charge is recalculated quarterly by the Energy Commission. TNB billing systems sometimes apply the wrong ICPT coefficient for your tariff class or billing cycle. We reconcile up to 12 months against the official EC gazette.
Maximum Demand Penalties
MD penalties are triggered when you exceed your registered demand in any 30-minute block. We model your half-hourly load profile to find avoidable demand spikes, identify months where penalties were incorrectly assessed, and recommend demand setpoint adjustments.
Power Factor Surcharge
TNB charges a surcharge when average power factor drops below 0.85. Many buildings have this from legacy HVAC or pump loads — and pay it silently for years. We calculate the correction capacitor bank size needed to eliminate the charge.
Connected Load Mismatch
If your registered connected load in TNB's system is higher than your actual installed load, you may be paying higher minimum charges unnecessarily. We audit your Single Line Diagram against TNB records and file a downward revision where eligible.
Time-of-Use Opportunity
Industrial D and E-tariff customers may benefit from shifting load to off-peak windows under TNB's TOU structure. We model your 12-month consumption pattern against peak/off-peak/super-off-peak rates and calculate the optimal shift schedule.
