Electricity tariffs in Malaysia are designed to accommodate different industries, usage patterns, and operational needs. However, many businesses are still subscribed to tariffs that do not align with their actual consumption behaviour—leading to avoidable overspending.
Tariff Optimisation is the process of analysing your energy consumption and selecting the most cost-efficient tariff available under TNB.
Step 1: Comprehensive Usage Pattern Analysis
Energy consultants begin by analysing your:
-
Peak vs. off-peak trends
-
Daily load profiles
-
Weekend and holiday usage
-
Maximum Demand behaviour
-
Seasonal fluctuations
This step reveals whether your business is using energy efficiently or simply consuming out of habit.
Step 2: Identifying the Most Cost-Effective Tariff
With over a dozen TNB tariffs available for commercial and industrial customers, choosing the right one is not straightforward.
Optimisation identifies whether your business should switch to:
-
A demand-based tariff
-
A non-demand tariff
-
A Time-of-Use (TOU) tariff
-
A lower voltage tariff class
Each option impacts your energy budget differently.
Step 3: Power Factor & Demand Charge Evaluation
For industrial and large commercial users, demand charges and power factor penalties form a sizable portion of the bill.
Optimisation determines whether improvements—such as capacitor banks, staggered machine start-ups, or load redistribution—can fix recurring penalties.
Step 4: Cost Simulation & Savings Projection
Energy analysts run simulations comparing your current tariff against alternatives. Businesses often discover that a simple tariff switch results in 10–25% cost savings, without changing any equipment or processes.
Step 5: Implementation & Ongoing Monitoring
Once the optimal tariff is confirmed, your consultant will:
-
Assist with the tariff change process with TNB
-
Monitor the first 3 months of billing
-
Validate that savings match the simulation
Corporate Insight
In Malaysia’s increasingly competitive business landscape, tariff optimisation gives organisations a straightforward path to reducing operational expenditure without sacrificing productivity.
