THERE has been a lot of pushback on the recent proposal to raise the base tariff for electricity in Peninsular Malaysia in the second half of the year, which means higher bills especially for commercial and industrial users.

The hike is to reflect the higher fuel costs and larger investments required to meet the rising demand for electricity, notably from data centres sprouting up across Malaysia, and the intermittency of renewable energy, the supply of which is expected to soar in the country.

Some quarters point out that Malaysia’s base electricity tariff now exceeds that of Vietnam and Indonesia (see chart), while others view this as part of the country’s journey away from low-cost to higher-value-added manufacturing. Besides that, the government needs to rationalise subsidies due to fiscal constraints.

It is worth noting that charging consumers below costs could have a lasting impact on the Malaysian power sector’s ability to maintain its world-class service reliability. The water sector, which has suffered underinvestment over the years and whose tariffs have been below costs since at least 2010, is an example of this. As much as 35% of treated water in the country is lost through problems like pipe leakages. For some states, non-revenue water is as much as 61%, meaning that more water is wasted than used.

To recap, Tenaga Nasional Bhd (KL:TENAGA), which operates the power grid in Peninsular Malaysia, announced on Dec 26 a proposed adjustment of the base electricity tariff to 45.62 sen/kWh in the fourth regulatory period (RP4, from 2025 to 2027) from 39.95 sen/kWh in RP3 (from 2022 to 2024).

The utility giant pointed to higher fuel costs assumption — coal and gas — as the main reason for the increment. Indeed, the proposed 14.2% rise is not the steepest. In 2009, the base tariff went up 24% to 32.5 sen/kWh from 26.2 sen.

“A major part of the tariff is fuel prices. We know, over the past few years, fuel costs have fluctuated quite drastically … We need to do good forecasting of what the fuel prices are going to be,” said Datuk Nazmi Othman, who was then Tenaga’s chief financial officer, at a media briefing on the proposed RP4 adjustment.

“When fuel prices fluctuate above the base tariff assumption, Tenaga ‘has to fund first’ for six months before it is compensated by the additional tariff surcharges in the following six months under the ICPT (imbalance cost pass-through),” he explained just a few days before his retirement this year.

Should fuel costs fall — for example, a big drop in coal prices to below the forecast level — end-users would be given a rebate, which will bring down the tariff.

The moving parts

However, fuel costs are not the only component in electricity tariffs, which include charges for power plants to have sufficient capacity on-call.

Fuel and generation costs make up about 70% of the base tariff, while the remaining 30% largely comprises costs to operate, maintain and upgrade the national grid (also called the regulated asset base or RAB).

In its announcement, Tenaga disclosed that it would raise its grid and distribution network capital expenditure (capex) to RM26.5 billion in RP4 (2025-2027) up from RM20.55 billion in RP3 (2022-2024). The utility giant will bump up operating expenditure (opex) to RM20.782 billion from RM17.96 billion in RP3.

The higher expenditures are mainly due to the electrification trend as there is an increasing number of daily items powered by electricity, including electric vehicles, smartwatches, cashless payment devices and data centres, which require electricity 24/7.

Furthermore, the grid infrastructure needs to be improved to withstand an increasingly volatile electricity flow amid the influx of solar panel installations on the rooftop of households and commercial premises such as shopping malls. And now that third-party grid access has been allowed, the use of solar energy, the supply of which is intermittent depending on weather conditions, is expected to rise substantially.

Considering the intermittency of solar power, the country needs to plant up more capacity to ensure sufficient supply is available to fill the gap. It is estimated that there will be an increase in electricity demand of 7.7gw from data centres alone by 2030, representing 38.37% of the peak demand of 20.07gw in July 2024.

Tenaga reportedly projected an electricity demand growth of 5.8% to 6.3% in 2024 alone. Besides, the annual electricity consumption per capita may soon exceed 5,000kWh for the first time, even as electronic devices become increasingly energy-efficient.

Energy costs are rising globally. Few may argue about the need to raise electricity tariffs. However, the debate is on whether the quantum of the hike is justified. The lack of details on the RP4 determination does not help, according to manufacturers and players in the power industry contacted by The Edge.

Apart from the capex, opex and cost of capital allocation for Tenaga’s grid and distribution network (unchanged at 7.3%), RP reviews in the past disclosed other components that determined Tenaga’s returns from its transmission, distribution and retail businesses.

There was an item-by-item breakdown of the base tariff components, how big the grid assets can be and how much revenue it can collect from those assets. The transparency will help the industry and the public to understand that while the base tariff is higher, Tenaga’s profitability from grid management is also regulated. 

It is understood that the government is reviewing the tariff structure to better reflect the costs amid an increasingly diverse group of consumers, such as those with solar panels or battery storage.

The tariff structure indicates that Tenaga also needs to consider charging for connecting energy transition projects, to ensure the capex incurred does not spill over into the tariffs for households that do not use the infrastructure. This would be crucial for the utility giant to cover its expenses should it be required to roll out its contingent capex, which could be up to RM16.267 billion, to support the energy transition journey.

Long overdue

As for the subsidy rationalisation, few may disagree that the current government has made a good effort by adjusting the ICPT surcharge closer to the actual market price of fuel. Additionally, it has removed the blanket rebates for high-consumption households to pave the way for a fairer tariff structure.

However, much still needs to be done. For example, the lowest tier of household tariffs for monthly consumption below 200kWh (or monthly bill of RM43.60) has been maintained at 21.8 sen/kWh since 1997, or for 27 years. The second tier (201-300kWh or monthly electricity bill of RM77 and under) has been maintained at 33.4 sen/kWh since 2009, or for 15 years.

Prime Minister Datuk Seri Anwar Ibrahim has said the tariff adjustment is not expected to affect 85% of households, which reportedly consume 20% of the electricity supply. Recall that at this point, only the top 1% of households with monthly bills of more than RM708 have a surcharge while most households enjoy a rebate.

Even with the current ICPT surcharge, there still leaves RM2.4 billion that the government needs to subsidise in 1H2025, according to an FAQ on ICPT posted by the Single Buyer, an entity authorised pursuant to the Electricity Supply Act (ESA) 1990 to conduct electricity planning and manage electricity procurement services for Peninsular Malaysia.

In RP3 (2022-2024), the electricity subsidy totalled RM20.7 billion, or about 2% of federal government revenue (see chart).

The Malaysian public is currently using electricity at below costs, which are covered by the government’s coffers as well as some contributions from the power plant operators to the Electricity Industry Fund, or KWIE.

Subsidised power partly produced by cheap gas

Deputy Prime Minister and Minister of Energy Transition and Water Transformation Datuk Seri Fadillah Yusof said on Dec 27 that RP4 coal prices are projected at US$97 per tonne, up 22.78% from US$79 per tonne in RP3.

For natural gas, the price floor and ceiling is RM24 and RM35 per mmbtu in RP4, compared with RM24 and RM30 per mmbtu in RP3 — a 16.7% increase in the price ceiling for usage below 800 mmscfd. Any gas volume consumed above that (Tier 2 gas price) is projected at RM46 per mmbtu in RP4, up from RM35 per mmbtu in RP3.

Coal and natural gas are the two key fuels for power generation in Malaysia, making up more than 79% of the fuel mix.

Actually, electricity users are currently paying a surcharge to compensate for fuel costs that are higher than the projections for RP4. For example, a 16 sen/kWh surcharge was imposed on medium to high voltage commercial and industrial users in 2H2024 to reflect the fuel costs for the previous six months.

High-consumption households are paying a 10 sen/kWh surcharge. The rate has been maintained in 1H2025.

The charges are based on the average coal price of US$112.9 per tonne in 1H2024. This is still 16.4% higher than the RP4 benchmark of US$97 per tonne. Similarly, the Tier 2 gas price average was RM47.4 per mmbtu, which is 3% higher than the RP4 benchmark.

Should fuel costs drop further, consumers could potentially pay lower than current payments despite the upward revisions in the RP4 benchmarks. Coal and natural gas prices already trended slightly lower in 2H2024, according to data from the Energy Commission’s website.

As for natural gas, the Tier 1 gas price of RM24 to RM35 per mmbtu for the first 800 mmscfd represents the bulk of gas supply to the power sector. Between 2022 and 2024, Malaysia’s reference price for LNG ranged from RM33.97 to RM58 per mmbtu, with an average of about RM43, compared with the highest forecast of RM35 for the period.

Natural gas is a finite resource, so Peninsular Malaysia is bringing in more gas from places like Australia. The fuel is imported at market prices but charged with the tariff on a blanket basis at a discount.

In line with the government’s policy to do away with a blanket subsidy, a discounted fuel cost is an issue that has to be addressed so the gains can be channelled to the public in a targeted manner.

The government has given itself more than six months to finalise the new tariff structure, and the public deserves to know the details of the RP4 determination. Although RP3 was implemented without the details being published at the outset — unlike during RP2 (2018-2020) — that does not mean this is acceptable, especially when the government wants to rationalise the electricity subsidy further. In a nutshell, this is a reallocation of taxpayers’ money from subsidising electricity to other purposes.

To quote an Energy Commission electricity pricing unit department head in a 2017 interview, the tariff adjustment should ensure consumers know they are paying the cost of electricity tariffs based on “actual costs formulated transparently and systematically”.

RP4 hints at upside for Tenaga but regulatory risks remain

Tenaga Nasional Bhd’s (KL:TENAGA) share price, which almost tested the RM15 mark at the end of last year after the company proposed a base tariff hike for 2025-2027, has fallen more than 12% following the government’s announcement that the proposal is still under review.

Despite the uncertainties, analysts believe Tenaga’s fundamentals remain solid, although opinions are divided on the extent of the upside to its share price stemming from the increased demand for electricity given the strong pushback against the recent fourth regulatory period (RP4) proposals.

Analysts are generally positive on the proposed RP4 determination, which includes a higher base tariff, increased base capital expenditure (capex) and operating expenditure (opex), and sustained allowed cost of capital. The recent win of a 500mw large-scale solar project adds to the positive sentiment. Nevertheless, the utility giant’s average target price (TP) of RM16.28 has remained largely unchanged since September, three months before the RP4 announcement.

Key areas of focus include the allowable electricity demand growth and how much of it can contribute to earnings; revenue and price caps related to its transmission, distribution and retail businesses; and clarity on how Tenaga can recoup the contingent capex meant for transition-induced grid upgrades but not included in the base tariff.

The proposed base tariff revision — a 14.2% increase to 45.62 sen/kWh from 39.95 sen/kWh — does not directly translate into bumper earnings for the utility giant. This adjustment mainly accounts for fuel price assumptions, which together with other power generation costs, make up 70% of the tariff. Just 30% of the tariff is actually related to Tenaga’s regulated transmission, distribution and retail businesses.

Tenaga’s base grid capex for 2025-2027 is proposed at RM26.5 billion, a 28.9% increase from RM20.55 billion in RP3 (2022-2024). The opex is estimated at RM20.782 billion, up 15.7% from RM17.96 billion in RP3. Analysts view the larger capex positively as it increases the size of the company’s regulated assets, which are allowed an unchanged cost of capital of 7.3%.

However, AmBank Research, which has the lowest TP at RM12.60, expects Tenaga might not fully benefit from excess electricity demand. It estimates allowable annual electricity demand growth at 3% for 2025-2027, compared to 1.7% in RP3. This contrasts with Tenaga’s forecast of 5.8% to 6.3% growth in 2024 alone.

Others are more optimistic. Macquarie Equity Research — with an “outperform” rating and TP of RM16.40 — anticipates an average demand growth of 4.7% for RP4 and forecasts 33% year-on-year earnings growth in 2025. Meanwhile, TA Research expects “a more aggressive growth rate” for RP4 compared to RP3’s 1.7% per annum.

Apex Research highlighted upside potential from the newly introduced contingent capex of RM16.267 billion introduced in RP4. To fund this, analysts suggest project-specific premium charges for consumers directly benefiting from these assets, such as wheeling or “system access” charges for third parties trading green electricity under the Corporate Renewable Energy Supply Scheme (CRESS).

“In a best-case scenario where all contingent capex is fully utilised, we estimate a 10.2% increase in annual average allowed return or an additional RM500 million in returns annually compared to the base case,” said Apex Research.

However, RHB Research noted uncertainties about whether Tenaga will be entitled to full regulated net returns based on the total allowed capex. “We maintain our earnings estimate for now but we see an upside of 5% to 7% to our net regulatory returns if the full capex numbers are being pencilled in,” it said.

While the government’s RM2.39 billion allocation to maintain tariffs in 1H2025 underscores the effectiveness of the imbalance cost pass-through (ICPT) mechanism, regulatory risks persist. Historical precedents show similar risks.

In January 2022, the Energy Commission announced that the tariff rates for domestic users would be maintained, without elaborating on base tariff revisions. On Feb 24, 2022, Tenaga said in a filing that its electricity tariff rate and structure “will continue to be in effect”.

At the time, the industry incorporated an RP2 base tariff of 39.45 sen/kWh. But months later, a higher base tariff of 39.95 sen/kWh emerged.

At RM13.12 per share, Tenaga’s forward price-earnings ratio for FY2025 reflects these RP4 assumptions, trading at its five-year average of around 16 times. This compares with those of its peers like YTL Power International Bhd (KL:YTLP) (10.4 times), Malakoff Corp Bhd (KL:MALAKOF) (12.6 times), Mega First Corp Bhd (KL:MFCB) (9.2 times) and Solarvest Holdings Bhd (KL:SLVEST) (25.3 times).

As at Jan 16, Tenaga had 16 “buy” calls, five “hold” and one “underweight”, with target prices ranging from RM12.60 to RM20.60. At its share price of RM13.12, the group’s market capitalisation stood at RM76.27 billion, with trailing and forward dividend yields of 3.51% and 4.03% respectively.

For the nine months ended Sept 30, 2024 (9MFY2024), Tenaga posted a net profit of RM3.74 billion on revenue and under-recovery (to be claimed back under the incentive-based regulation) of RM49.73 billion, resulting in a net margin of 7.53%. The utility giant declared interim dividends of 25 sen per share for the nine-month period and 46 sen per share for the full year in FY2022 and FY2023.

Major shareholders of Tenaga include Khazanah Nasional Bhd (direct stake of 20.74%), the Employees Provident Fund (18.47%), Amanahraya Trustees Bhd — Amanah Saham Bumiputera (7.46%) and Kumpulan Wang Persaraan Diperbadankan (6.95%).
