# Malaysia's Electricity Tariff and the National Energy Transition

> Malaysia's new electricity tariff structure, effective 1 July 2025, splits the bill into five cost-reflective components, while the National Energy Transition Roadmap (NETR) targets 70% renewable energy capacity by 2050.

Your electricity bill now looks different — and it is not a printing error. Since 1 July 2025, every kilowatt-hour flowing into Malaysian homes and factories has been calculated using a far more detailed formula, the result of a major reform of the power sector. This change is not merely a matter of bill costs; it is closely tied to the country's direction toward renewable energy.

## What changed in the electricity tariff from July 2025?

The Energy Commission (ST) set an average base tariff of **45.40 sen/kWh** for *Regulatory Period 4* (RP4), effective **1 July 2025 to 31 December 2027** in Peninsular Malaysia. According to the Energy Commission, the average overall cost of the electricity tariff falls by up to **19%** compared with the previous regulatory period (RP3). This structure operates under the *Incentive-Based Regulation* (IBR) framework, which separates charges according to the cost of generation, transmission and service.

The most noticeable change is how the bill is broken down. The old tiered-block system is replaced with a **component-based structure** — your bill now lists Energy, Capacity, Network and Retail charges, as well as the **Automatic Fuel Adjustment (AFA)**, separately. Users are also categorised by voltage level: low voltage (most homes and small businesses), medium voltage, and high voltage (large factories and industry).

The AFA replaces the old ICPT (*Imbalance Cost Pass-Through*) mechanism. The difference matters: ICPT was updated every six months, but **AFA is recalculated every month** by the Energy Commission according to fluctuations in fuel prices and the foreign exchange rate. This means the bill can move up or down each month in line with global markets.

## What is the rate for each component for households?

For low-voltage domestic customers, the Energy Commission's official RP4 tariff schedule breaks the charges down as follows:

| Component | Rate (low-voltage domestic) |
|---|---|
| Energy Charge (up to 1,500 kWh per month) | 27.03 sen/kWh |
| Energy Charge (above 1,500 kWh per month) | 37.03 sen/kWh |
| Capacity Charge | 4.55 sen/kWh |
| Network Charge | 12.85 sen/kWh |
| Retail Charge | RM10 per month |
| AFA | Adjusted monthly according to fuel cost |

An important figure to remember: the Energy charge rises from 27.03 to 37.03 sen/kWh once consumption exceeds 1,500 kWh per month — a higher rate is applied to larger consumption.

## Who is protected and who pays more?

The RP4 design concentrates assistance on frugal users rather than applying it across the board. According to the Energy Commission's official media release and the RP4 tariff schedule, two tiers of the **Energy Efficiency Incentive (EEI)** are the key protection mechanism:

- **A rebate of up to 25 sen/kWh** for domestic users consuming **1,000 kWh and below** per month.
- **Waiver of the RM10 monthly retail charge** for users of **600 kWh and below**.

The Energy Commission states that more than **23.6 million** domestic users in the Peninsula enjoy fairer rates under the new structure, while media reports estimate that around 23 million users are expected to remain unaffected, with homes using 900 kWh or less likely to see a slight reduction in their bill. Poor households registered in the e-Kasih system continue to receive an **electricity bill rebate of up to RM40 per month**, as confirmed by the Energy Commission.

By contrast, the tariff's impact is shifted more toward high-volume users — large homes, businesses and industry. The stated rationale is a **targeted subsidy** approach: those who use the most energy pay rates closer to the true cost, and public support is focused on lower-income groups. For businesses, this can mean higher operating costs, some of which may be passed on to the prices of goods and services.

## Where does TNB fit into this equation?

Tenaga Nasional Berhad (TNB) remains the integrated utility managing the national grid, but ST sets how much revenue TNB is allowed to collect under the IBR framework. This model separates TNB's revenue from the volume of energy sales — protecting the utility from fuel-price fluctuations (through AFA) while incentivising operational efficiency.

Importantly, the RP4 structure is designed to **finance grid investment**. The transition to renewable energy requires a smarter, more flexible grid to absorb intermittent solar power. The Capacity and Network components, now transparent in the bill, are how TNB raises capital to upgrade this infrastructure.

## How does this tariff support the National Energy Transition Roadmap?

The cost-reflective tariff is seen as part of the financial foundation for the **National Energy Transition Roadmap (NETR)**, launched in 2023. The NETR sets the following targets for the electricity generation mix:

| Year | Renewable energy capacity target |
|---|---|
| 2025 | 31% |
| 2035 | 40% |
| 2050 | 70% |

By 2050, Malaysia is also committed to achieving **net-zero greenhouse gas emissions**. The NETR is organised around six energy transition levers: Energy Efficiency, Renewable Energy, Hydrogen, Bioenergy, Green Mobility, and Carbon Capture, Utilisation and Storage (CCUS).

These six levers translate into **10 flagship projects** expected to attract more than **RM25 billion** in investment, create **23,000 job opportunities**, and reduce emissions by more than **10,000 Gg CO2 equivalent per year**. Over the long term, the NETR's responsible transition initiatives are projected to unlock investment opportunities of between RM1.2 and RM1.3 trillion by 2050, contribute an additional roughly RM220 billion to GDP, and create around 310,000 green jobs by 2050.

## What does it mean for businesses?

For commercial and industrial users, three implications stand out:

1. **Cost transparency** — separating the components lets businesses analyse where money is spent (capacity versus energy) and manage peak demand more strategically.
2. **AFA line risk** — monthly exposure to fuel prices means energy budgets need to be more flexible; hedging and energy efficiency become more valuable.
3. **Rooftop solar economics** — as grid rates rise for large users, installing rooftop solar and participating in renewable energy programmes become more attractive in terms of returns.

In short, the new tariff structure rewards energy-efficient users, in line with the direction of the NETR.

## What's next

The most practical thing to monitor is the **monthly AFA rate** published by the Energy Commission — it is the real determinant of whether the bill rises or falls each month. Check the official TNB tariff calculator to estimate your bill based on your consumption profile, and if your usage is close to 1,000 kWh, energy efficiency measures can keep you in the incentive zone.

For businesses, RP4 runs until 31 December 2027, so now is the time to weigh an energy audit and rooftop solar options. For investors, the NETR flagship projects and levers such as hydrogen and CCUS are areas to watch as implementation details and green incentives such as GITA/GITE are expanded. Check back on this page when tariff adjustments and progress toward the 2025 NETR targets are officially updated.
