📈 Malaysia Electricity Cost Update: AFA Turns Positive — What It Means for Businesses & Homes

In May 2026, Tenaga Nasional Berhad (TNB) implemented a positive Automatic Fuel Adjustment (AFA) of +1.38 sen/kWh, marking a shift from April’s negative adjustment (-0.47 sen/kWh). This signals a rising electricity cost environment, driven by fuel price fluctuations and currency factors.

🔍 What is AFA?

The Automatic Fuel Adjustment (AFA) is a monthly mechanism that adjusts electricity tariffs based on:

• Global fuel prices (e.g. coal, gas)

• Foreign exchange rates

In short:

When fuel costs rise → electricity bills go up
When fuel costs drop → electricity bills go down

⚡ May 2026 AFA Snapshot

• April 2026: -0.47 sen/kWh (rebate)

• May 2026: +1.38 sen/kWh (surcharge)

• Trend: Moving into cost increase territory

Additionally, forecasts show continued surcharges:

👉 Implication: Electricity costs are expected to remain elevated in the near term.

🏭 Impact on Industrial (ToU Tariff)

For Medium Voltage (MV) and High Voltage (HV) users under Time-of-Use (ToU) tariffs, the AFA surcharge directly increases energy cost percentages:

Medium Voltage (MV)

• Peak Rate: 31.32 sen/kWh
  → AFA impact: +4.41%

• Off-Peak Rate: 27.23 sen/kWh
  → AFA impact: +5.07%

High Voltage (HV)

• Peak Rate: 44.52 sen/kWh
  → AFA impact: +3.10%

• Off-Peak Rate: 40.43 sen/kWh
  → AFA impact: +3.41%

🏠 Impact on Residential Users

• Base Rate: 44.43 sen/kWh

• AFA Impact: +3.11%

While domestic users may have partial protections (depending on consumption tiers), the underlying cost pressure is rising.

📊 Key Takeaways

1. Electricity Costs Are Trending Up

The shift from rebate to surcharge — combined with a 3-month positive forecast — indicates a sustained increase in energy costs.

2. Industrial Users Are More Exposed

Manufacturers and commercial operators on ToU tariffs face:

• Higher operational costs

• Greater sensitivity to peak/off-peak usage

3. Cost Volatility is the New Normal

AFA fluctuates monthly — meaning budget predictability is reduced.

🌞 Strategic Response: Why Solar Matters More Now

With AFA turning positive, solar energy becomes increasingly attractive:

• ✅ Hedge against rising tariffs

• ✅ Reduce dependency on grid fluctuations

• ✅ Lower long-term operating costs

• ✅ Improve ESG positioning

For industrial users especially, combining:

• Solar PV (rooftop)

• Battery Energy Storage (BESS)

• Peak shaving strategies

can significantly mitigate AFA-driven cost increases.

🚀 Final Thought

The May 2026 AFA update is not just a short-term fluctuation — it’s a signal of structural energy cost pressure.

Businesses that act early to optimize energy usage and adopt solar solutions will gain a competitive cost advantage.
