Thailand Scraps Data Centre Power Cap, Opens Clean Electricity Market to All Industry

 

Energy Minister Ekanat Promphan lifts the 2,000MW cap on direct clean power deals for all industry, while shielding households from data centre-driven cost rises.

 

Thailand's Energy Minister Akanat Promphan has announced the removal of a 2,000-megawatt cap on direct clean power trading for data centres, opening the previously restricted scheme to every industry seeking renewable electricity, as the government moves to accommodate a surge in demand driven by digital infrastructure.

 

Speaking at the KT Dialogue forum on Friday, held under the theme "New Horizon: Energy Transition: Smart Grid — Reshaping Tomorrow's Renewable Energy Grid" and hosted by Krungthep Turakij, Akanat said a two-year regulatory sandbox that had limited direct power purchase agreements (PPAs) to 2,000 megawatts specifically for data centres had now been fully lifted following the latest meeting of the National Energy Policy Council (NEPC).

 

"We are not limiting it to data centres any more. It is open to every industry that needs electricity," he told an audience of government officials, business leaders, investors and academics gathered to discuss the future of Thailand's economy.

 

The decision marks one of the most significant liberalisations of Thailand's electricity market to date, allowing any company — from semiconductor manufacturers to exporters facing European carbon tariffs — to strike direct deals with clean power producers rather than buying exclusively through the state utility.
 

 

 

Guarding against a hidden cost

The move comes with a caveat. Alongside the deregulation, the ministry is creating an entirely new electricity user classification — described by Akanat as "category nine" — specifically for data centres, to prevent their soaring demand from pushing up bills for households and other industries.

 

The minister was candid about why the safeguard was needed. Many data centre operators had publicly pledged to run on 100% renewable energy, he said, but the reality on the ground was different.

 

"You'd be surprised — when it comes down to it, they say clean power can wait. Right now, just give us any electricity, as long as there's enough," he said, recounting conversations with prospective data centre clients.

 

That matters because roughly 60% of Thailand's electricity is already generated from natural gas, and the country does not produce enough domestically.

 

Any additional load is met by imported liquefied natural gas (LNG), currently priced at around US$23 per unit on the open market — a cost that, once pooled into the national gas tariff, raises electricity prices "for everyone", Akanat said, not just the data centres driving the demand.

 

"It's not just data centres that get more expensive. Households get more expensive. Other industries get more expensive too," he said.

 

Separating data centres into their own tariff category means operators who import costly LNG-backed power will bear that cost themselves, rather than spreading it across the wider grid.
 

 

 

Under the new framework, data centres and other large users can instead choose to buy clean electricity directly from renewable producers through a "Third Party Access" (TPA) charge — effectively a wheeling fee covering transmission lines operated by the Electricity Generating Authority of Thailand (EGAT); distribution networks run by the Metropolitan or Provincial Electricity Authorities; plus system reliability and loss charges.

 

Because solar power is priced at roughly THB2.16 per unit and wind at about THB3, against an LNG-based production cost of more than THB5, Akanat argued that direct clean power purchases should ultimately work out cheaper than relying on the state grid, even after the TPA charge is added.

 

"If you choose to buy clean power through the direct market, it will end up cheaper than fossil-fuel-based electricity," he said.

 

 

 

Data centres as the new "breath of life"

Framing the wider policy shift, Akanat argued that electricity has effectively replaced oil as the fuel underpinning modern life and that data itself may become the next essential resource.

 

"Fuel, and now electricity, is our breath of life," he said. "But it is also the key that unlocks the door to the industries of the new world."

 

He acknowledged public unease about the rapid expansion of data centres in Thailand, including concerns over water and electricity consumption and community impact, but stopped short of opposing their growth.

 

"We are not saying the country should have no data centres. But there has to be a review of the benefits to the economy, weighed against the impact on the environment, communities and the people who live nearby, and above all the resources they consume," he said.

 

 

 

Wider grid overhaul

The data centre announcement was framed as part of a broader liberalisation of Thailand's power market. Akanat said the ministry had already moved to end the exclusive "Enhanced Single Buyer" model, under which EGAT alone purchased and resold electricity, in favour of a parallel free market allowing direct buyer-seller matching.

 

He also pointed to a shift in the role of household consumers, who can now register as "prosumers" — both users and small-scale producers — by selling surplus rooftop solar power back to the grid.

 

Approval processes, he said, had been streamlined to a single point of contact through the regional or metropolitan electricity authorities, cutting timelines to seven days for self-consumption installations and 30 days for those selling electricity back, down from a process that previously took well over a year and involved multiple agencies.

 

A separate scheme allows households with roof space but no capital to have solar panels installed and financed by the state, with monthly generation revenue split between loan repayment and a discount on the household's own electricity bill; after seven years, ownership of the panels — and their income stream — passes to the homeowner.

 

Akanat also flagged plans to raise the nationwide rooftop solar buyback quota, currently capped at 500 megawatts, and to extend buyback contracts beyond the current ten years, as well as future support for "independent power supply" models allowing industrial estates, condominiums, and even villages to generate, distribute and consume power within a single self-contained system.

 

Tying the announcements together, he said none of the reforms would function without a genuine smart grid — encompassing demand forecasting, real-time monitoring, storage and data-sharing between household users, distribution operators and system regulators.

 

"Without data to monitor how much is being used, a smart meter is useless," he said.

 

 

 

A narrowing window

Akanat closed his address by framing Thailand's energy transition as urgent rather than optional, citing gas price shocks from the Russia-Ukraine war and renewed volatility from conflict in the Middle East, alongside mounting climate pressures.

 

"We don't really have much choice left, and we don't have time either," he said, comparing the pressure to that of a student cramming before an exam.

 

He appealed for the reforms to continue regardless of political change: "Everything can change — except one thing: the ministry has to keep going."
