FAQ

Peak Shaving Questions Answered

Everything you need to know about Maximum Demand reduction in Malaysia.

Maximum Demand is the highest amount of electrical power (kW) your facility draws in any 30-minute interval during a billing period. TNB charges you based on this peak, regardless of your average consumption. A single spike can set your MD charge for the entire month. Under RP4 tariffs, MD charges can be RM 30-45 per kW - a 2,000 kW facility pays RM 60,000-90,000 monthly JUST for MD!
