Dear industrial and commercial business owners and energy management leaders in Malaysia, have you ever been troubled by the high “Demand Charge” on your TNB bill? Do you know that besides energy consumption (kWh), your peak power demand (kW) within just a 30-minute window each month​ is the “hidden culprit” driving up your operational costs?

1. Understand TNB’s Policy to Save Money Precisely

Tenaga Nasional Berhad (TNB) typically uses a “two-part tariff” for large industrial users (e.g., factories, large shopping malls, office buildings). The electricity bill consists of two parts:

1.1 Energy Charges (kWh Charges):​ You pay for what you use. This is a variable cost.

1.2 Demand Charges (kW/MW Charges):​ This is a fixed cost, calculated based on your highest average power demand (i.e., “Maximum Demand”) over a continuous 30-minute period​ during the peak tariff hours​ of the month. Once this “record” is set, your fixed charge for the entire month will be based on it.

Core Pain Point:​ Without active management, simultaneously starting multiple high-power equipment (like central air conditioning, air compressors, large production lines) by chance can instantly spike your power demand, creating an expensive “monthly demand record” that locks you into high fixed costs for the whole month!

•Relying on the monthly bill?​ The bill is a “hindsight” report—the damage is done and cannot be changed.

•Estimating based on experience?​ Complex production processes and dynamically changing loads make experience unreliable.

•Manual recording?​ It’s inefficient and cannot capture instantaneous power fluctuations.

You need an intelligent solution that can monitor in real-time, provide early warnings, and help you proactively manage​ your power demand.

3. Our Solution: APM520 Premium Power Meter + Intelligent Platform, Tailored for You
We deeply understand the specifics of TNB’s policy (such as the 30-minute demand interval, weekday/weekend differentiation, peak/off-peak tariffs) and offer the APM520 Special Edition Demand Monitoring & Management Solution, specifically developed for the Malaysian market.

Core Advantages of the Solution:

1.100% Compliant with TNB Billing Standards:

•Accurately Captures “Peak Tariff Demand”:​ Ordinary meters only record the overall maximum demand. Our specially programmed APM520 can strictly distinguish tariff periods, accurately calculating and recording the demand that occurs only during TNB’s specified peak hours. This ensures you are managing the core factor that determines your bill, avoiding ineffective efforts.

•Configurable Parameters:​ Supports setting the TNB-required 30-minute demand period​ and 1-minute sliding window, ensuring compliant and accurate data collection.

2.Real-Time Visibility & Over-limit Alerts:

•Clear Dashboard:​ Via the compatible AWT gateway and EIOT energy IoT platform, you can view the dynamic curve of your facility’s total power demand in real-time on a computer or large mobile screen.

•Pre-set Demand Thresholds:​ You can set demand alert limits based on your TNB contract capacity or internal management goals. When real-time demand approaches the critical point, the system sends early warnings via SMS, app push notifications, etc., providing your management team valuable time to intervene.

3.Data-Driven Decisions to Proactively Reduce Costs:

•Traceability & Analysis:​ The system completely records the historical maximum demand and its precise time of occurrence, helping you analyze which day, shift, or equipment caused the high demand, enabling targeted optimization of production schedules.

•Implementing Demand Management Logic:​ Upon receiving an alert, managers can take action, such as: staggering the startup of high-power equipment, slightly adjusting air conditioning temperatures temporarily, or activating backup generators—actively “shaving the peak and filling the valley” to keep the average power within the 30-minute window below the safety line.

4. Successful Application Scenarios

•Manufacturing Plants:​ Avoid simultaneous startup of injection molding machines, furnaces, large machine tools.

•Commercial Complexes/Hotels:​ Manage the coordinated operation of central air conditioning, elevators, and lighting systems.

•Water Treatment Plants:​ Intelligently schedule the start/stop of large water pumps.
