TNB Tariff Up 13.6%: How to Cut Your Bill in 2025

Starting 1 July 2025, Tenaga Nasional Berhad (TNB) will increase its base electricity tariff across Peninsular Malaysia by 13.6%. This marks the start of Regulatory Period 4 (RP4) — a three-year plan driven by the need for major investments in power generation and grid upgrades.

For many Malaysians, this means one thing: higher TNB bills. And with the cost of living already rising, the new TNB tariff adds extra pressure on household and business budgets alike.

The silver lining? You don’t have to passively accept this. By switching to solar energy, you can take back control of your energy costs and lock in long-term savings. And thanks to GetSolar’s flexible Rent-to-Own (RTO) plan, going solar is now accessible than ever—zero upfront cost, full ownership, and fixed monthly payments.

What’s Behind the New TNB Tariffs in 2025?

Since 2014, the base electricity tariff has remain unchanged at 39.95 sen per kilowatt-hour (kWh). But from 1 July 2025, Tenaga National Berhad (TNB) will rise to 45.4 sen/kWh, marking the first increase in over a decade and slightly lower than the previously approved tariff at 45.62 sen/kWh. . The change is part of Regulatory Period 4 (RP4), which sets the tariff structure for 2025 to 2027.

This revision goes beyond just rising fuel costs. It reflects a major shift in how TNB is investing in the country's energy future. The utility plans to double its capital expenditure to RM42.9 billion, channelling funds into:

• Upgrading ageing infrastructure
• Expanding renewable energy capacity
• Supporting future-ready systems like battery storage, electric mobility, and smart grid interconnections

These efforts align with the National Energy Transition Roadmap (NETR), which charts Malaysia’s blueprint for a low-carbon future.

While these upgrades are necessary for long-term sustainability, they do come with a short-term cost: higher TNB bills for consumers like you.

What’s Driving the TNB Tariff Increase?

The main reason behind the new TNB tariff is the rising cost of generating electricity. Malaysia still relies heavily on fossil fuels like coal and natural gas, which are prone to global price swings. As fuel prices go up, so does the cost of producing power.

To manage these changes, Tenaga Nasional Berhad uses a mechanism called the Automatic Fuel Adjustment (AFA), replacing the old scheme: ICPT (Imbalance Cost Pass-Through). It allows TNB to adjust the tariffs based on actual fuel costs monthly, instead of bi-annually. While the July 2025 electricity tariff hike is already confirmed and applied, future changes could still happen depending on global energy trends. This means your electricity bill could fluctuate more often, depending on global fuel prices and exchange rates. In short: higher energy costs may be coming faster and more frequently. If you’re looking for a way to take control and protect your household from unpredictable hikes, solar might just be your smartest move yet.

But it's not just fuel costs. Electricity demand is rising too—driven by new housing developments, more appliances per home, and growing number of electric vehicles (Es). All these factors put extra pressure on energy supply and infrastructure.

TNB estimates that households with medium to high usage of generated electricity will feel a significant impact. This includes families in terrace houses, high-rise condos, and landed homes using air conditioning, water heaters, or EV charging.

Small business owners whether running a clinic, café, or home office could also face higher TNB bill. Even if your monthly usage isn't unusually high, the added cost over time adds up quickly.

What Does the New TNB Tariff Mean for Your Bill?

Let’s break it down with a real-world example:

If your household uses 800 to 1,000 kilowatt-hours (kWh) of electricity per month, your current TNB bill likely falls between RM370 to RM520. With the 13.6% tariff increase, that range could rise to RM400 to RM590 per month — that’s up to an increase of RM70 monthly, or nearly RM840 more per year for the same usage.

For many families, that's money that could go towards savings, groceries, or school expenses.

While TNB has introduced the new Energy Efficient Incentive which works as a rebate for houses which use low amount of electricity monthly, houses which use a high amount of electricity would not be eligible for this incentive and still be affected by the tariff hike.

And that is exactly where solar energy makes  a  difference. By generating your own power, you can reduce your reliance on the TNB electricity tariff and take control of your monthly costs with no surprises, just steady savings.

Rent-to-Own Solar: Fixed Cost, Zero Stress

Solar isn’t just a green decision — it’s a smart financial move. By installing a solar system on your roof, you generate your own electricity, reduce your dependence on the grid and shield yourself from future TNB tariff hikes.
