BANGKOK, THAILAND – Thailand’s energy regulator approved a power tariff increase that was set to raise household electricity bills from May 2026.
Power tariff to rise from May
The Energy Regulatory Commission (ERC) decided on new electricity rates for May to August 2026 at its meeting on 1 April 2026. The so‑called Fuel Adjustment Charge (FT) was set at 16.23 satang per unit.
Together with the base rate of 3.78 baht per unit, this resulted in an average price of 3.95 baht per kilowatt hour before value‑added tax. For an average household, the decision meant a noticeable additional burden.
The regulator described the move as a difficult balance between cost recovery and consumer protection.
“We must reflect the actual costs while at the same time protecting consumers.”
said Dr. Pullop Leesombatpaiboon, ERC spokesperson.
Middle East conflict drives energy costs
The increase was linked to developments far beyond Thailand’s borders. The conflict in the Middle East caused major disruptions on global energy markets.
Prices for liquefied natural gas (LNG) rose sharply, pushing up power generation costs. The state‑owned Electricity Generating Authority of Thailand (EGAT) expected fuel costs of 29.66 satang per unit in the coming months.
This level was almost double that of the previous period. The Thai government tried to cushion the worst effects, but officials said global market prices could not be ignored.
State shoulders 35.9 billion baht in costs
To ease pressure on consumers, EGAT initially assumed part of the burden. The state utility absorbed accumulated costs of 35.9 billion baht (about 900 million euros).
Authorities stressed that this was effectively a loan, not a grant. Ultimately, these costs were expected to be passed back to consumers in future tariffs.
For the moment, however, the move softened the immediate price shock.
“We are using all legal options to protect consumers.”
said Dr. Pullop. The regulator acknowledged that the final bill would come later.
Claw back fund offers partial relief
Officials pointed to at least one positive element in the package. The ERC drew on a relief fund financed from past excess revenues.
Around 9.47 billion baht (about 237 million euros) were returned through so‑called “claw back” funds. This translated into a reduction of 13.23 satang per unit compared with what the tariff would otherwise have been.
Without this mechanism, the average power price would have been significantly higher. The money came from earlier windfall profits of energy providers and now flowed back to the public, which the report described as a rare example of social balance.
Public demands lower rate as costs are laid out
Ahead of the decision, the authorities invited public comments. Of 340 submissions, 49 percent supported the new rate of 3.95 baht per unit.
Many respondents, however, called for a lower level of 3.88 baht per unit, seven satang less. The government presented calculations on what further cuts would cost.
A reduction of just one satang would require 706 million baht per month in additional funding. Meeting the requested seven‑satang cut would have needed almost 5 billion baht (125 million euros) in only four months.
“That is not feasible within the current budget.”
said Dr. Pullop.
Poor households hit hardest
The tariff rise was expected to affect low‑income groups most. About 14.3 million households used fewer than 200 units per month, accounting for 62 percent of all residential customers.
Providing relief only to this group would still require 366 million baht, according to the figures presented. Supporting households consuming up to 300 units – some 17.5 million households, or 76 percent – would cost 591 million baht.
“We must distribute the limited funds fairly.”
explained the ERC spokesperson. Nonetheless, many citizens reportedly felt abandoned by policymakers.
Summer heat and progressive tariffs push bills higher
Officials warned of another challenge for consumers. The Thai summer was described as becoming increasingly hot, driving up electricity use.
As temperatures rose, air conditioners ran at full capacity. Under Thailand’s progressive electricity tariff structure, the unit price increases with higher consumption, so heavy cooling in summer automatically leads to higher bills.
In response, the ERC called for energy‑saving measures.
“Everyone can reduce their consumption.”
appealed Dr. Pullop to the public.
ERC promotes ‘5 P’ power‑saving plan
To help households curb costs, the authority issued simple guidelines known as the “5 P” programme. The five elements stood for switching off, closing, adjusting, changing and planting.
The regulator highlighted air‑conditioning settings as a key factor. Setting air conditioners to 26 degrees Celsius could save up to 30 percent of energy, while regular maintenance of appliances also reduced consumption.
In the longer term, the ERC recommended energy‑efficient devices and rooftop solar installations. However, such investments remained expensive for many families and did not solve the immediate impact of the tariff hike.
Electricity prices become political flashpoint
Electricity costs emerged as a political tipping point. The government came under pressure to provide further relief as living costs continued to rise.
The opposition used the price increase to attack economic policy and question the handling of the energy crisis. Regulators said they would continue to monitor global energy prices closely.
The energy authority indicated that power tariffs could fall if the situation in the Middle East eased. Until then, households across the kingdom faced higher electricity bills at a time of already mounting expenses, as the effects of the distant conflict reached Thai power meters.
