Electricity Tariff Optimisation & Demand Analysis
Stop Bleeding Cash on the New "AFA" Mechanism & July 2025 Tariffs.
The rules changed on 1 July 2025. The Imbalance Cost Pass-Through (ICPT) has been replaced by the Automatic Fuel Adjustment (AFA). If you have not re-optimized your energy contract since the switch, you are likely overpaying. We help you eliminate penalties and secure the lowest possible rate under the new billing structure.

Electricity Tariff Optimisation is the financial engineering of your energy costs. It involves analyzing your load profile against TNB’s latest tariff structures (effective July 2025) to find the most cost-efficient configuration for your business.
Combined with Maximum Demand (MD) Management and Power Factor Correction, this service ensures resilience against Automatic Fuel Adjustment (AFA) charges.
It is not about turning off lights — it is about buying electricity smarter.
Why You Need This Now
The old billing assumptions no longer apply. The July 2025 regulatory shift introduced new financial risks that punish inefficiency.
- The "AFA" Shock: The Automatic Fuel Adjustment passes fuel cost fluctuations to consumers faster and more aggressively. On an inefficient tariff multiplier, AFA amplifies your total bill significantly.
- Maximum Demand (MD) Penalties: A single 30-minute spike in usage can trigger a high MD charge that impacts your entire month’s profitability.
- Power Factor Surcharge: If your Power Factor drops below 0.90 (Commercial) or 0.85 (Industrial), TNB imposes a 1.5%–3% surcharge. This adds cost without adding value.
- Cost of Inaction: Remaining on a legacy tariff structure means subsidizing competitors who have already optimized under the 2025 system.
What You Will Receive (The Deliverable)
We provide engineering-grade, simulation-backed data — not generic advice.
- Tariff Simulation & Switching Report: A detailed projection of your savings if you switch tariff classes (e.g., C1 to C2, or ETOU). Includes official documentation support for TNB submission.
- AFA Impact Assessment: Quantified analysis of how Automatic Fuel Adjustment affects your costs and how to reduce exposure.
- Maximum Demand (MD) Heat Map: A visual load profile showing exactly when and where costly demand spikes occur.
- Power Factor Capacitor Bank Specification: Precise kVAR calculation required to reach 0.95 Power Factor and eliminate penalties.

Frequently Asked Questions (FAQ)
- My bill increased after July 2025. Is it the AFA?
Likely yes. AFA replaced ICPT with a more dynamic pricing mechanism. An unoptimized tariff amplifies its impact. - Is switching TNB tariffs legal?
Yes. Customers may switch tariff categories once every 12 months if they meet technical requirements. - What is Maximum Demand (MD)?
MD is a charge based on your highest 30-minute usage peak. It funds infrastructure for peak capacity. - How much can we save?
Correcting tariff assignments can save 5%–15%. Fixing Power Factor may add another 3%–5%. - Do we need new machinery?
Usually no. Most optimization involves contract class and load scheduling adjustments. - What is ETOU?
Enhanced Time of Use offers lower off-peak rates and higher peak rates. We simulate whether it benefits your load pattern. - Why is my Power Factor low?
Typically due to damaged or undersized capacitor banks. - Can you guarantee savings?
We guarantee the accuracy of the mathematical simulation based on your load data. - How long does the analysis take?
Preliminary report within 5–7 working days after receiving 12 months of bills. - Why choose Techikara Engineering?
