Thailand’s Direct PPA pilot for data centres: What has changed since early 2026?
Since early 2026, Thailand’s Direct Power Purchase Agreement (Direct PPA) pilot for data centres has continued to move from policy design towards implementation. Regulators have progressed financial commitment requirements and integrated power-planning considerations into the project approval process. At the same time, Direct PPA is increasingly being discussed alongside broader issues of power availability, grid readiness and Thailand’s ability to support large-scale digital infrastructure investment.

The policy direction has also widened. On 15 July 2026, the National Energy Policy Council (NEPC) approved a package of electricity measures extending Direct PPA, delivered through Third Party Access (TPA), beyond data centres to industrial users, establishing a separate tariff class for data centre users, and directing the Energy Regulatory Commission of Thailand (ERC) to amend the Power Development Fund rules to enable contributions to be collected from data centre users and users holding Direct PPAs. The policy is therefore no longer confined to the data centre sector, although implementing regulations for the wider scope have not yet been issued. If implemented, the expansion to industrial users could significantly increase demand for renewable-electricity procurement through TPA arrangements and may influence future allocation of network capacity.

Several key commercial parameters remain outstanding, particularly the applicable grid-use charges on which the ERC has previously consulted. Even so, the overall structure is now substantially clearer than it was at the beginning of the year, and the key question is increasingly not whether Direct PPA will proceed, but whether the final tariff framework will make it commercially attractive.
1. Financial commitment requirements have moved forward
The ERC has developed, and the NEPC approved in principle on 15 July 2026, financial commitment requirements for large data centre users.
1. Financial commitment requirements have moved forward
As reported on 27 July 20261, large data centre users will be required to provide a bank guarantee or equivalent collateral of THB 4.5 million per megawatt of reserved capacity. For a 100MW hyperscale facility, this could translate into approximately THB 450 million of financial commitment. The timing, form and release mechanics of such security may become relevant considerations in project financing and liquidity planning. Based on the reporting, half of the security will be released once utilisation reaches 50% of the reserved capacity, with the balance released once utilisation reaches 70%. This financial commitment requirement is intended to discourage speculative reservations of capacity and to ensure serious participation, and is reported not to apply retroactively to projects already approved by the Board of Investment (BOI), but to extend to operators participating in the Direct PPA pilot.
1. Financial commitment requirements have moved forward
Participation in the pilot is therefore no longer simply a regulatory exercise. For hyperscale data centres in particular, financial security and capacity commitments may represent a meaningful project cost to be reflected in development budgets and financing arrangements.
2. The procedural framework is progressing, but key commercial terms remain outstanding
Through 2026, the procedural framework for the pilot has continued to develop, including matters relating to project selection and security for grid use. What remains outstanding is the tariff framework governing use of the transmission and distribution network, including wheeling charges and other grid-related costs.
2. The procedural framework is progressing, but key commercial terms remain outstanding
Although greater detail has emerged on eligibility, applicant selection and financial security arrangements, the economics of Direct PPA transactions cannot yet be fully assessed. The ultimate attractiveness of the regime will depend not only on the renewable electricity price agreed between the generator and the offtaker, but also on the charges associated with delivering that electricity through the grid.
2. The procedural framework is progressing, but key commercial terms remain outstanding
For investors and lenders, the principal unresolved issue is therefore how network-related charges will affect delivered electricity costs and long-term project economics.
3. Electricity planning must now be addressed earlier
One of the more practical developments for project developers is the increased emphasis on demonstrating electricity readiness at an early stage.
3. Electricity planning must now be addressed earlier
Under BOI Announcement No. Sor. 2/2569, dated 30 March 2026, projects in the relevant data centre categories must obtain a confirmation letter from the Office of the ERC before submitting an application for investment promotion. Announcement No. Sor. 2/2569 forms part of a package of three announcements, together with Nos. Sor. 9/2568 and Por. 3/2569, which also revised the promoted activity categories and technical conditions and introduced a mandatory Thailand benefit enhancement plan.
3. Electricity planning must now be addressed earlier
Electricity sourcing and power availability must therefore be considered at the beginning of project development rather than after investment promotion has been obtained. This is an important sequencing change for developers: power availability, network capacity and the proposed renewable energy strategy may need to be assessed together before the BOI application is filed.
4. Direct PPA is increasingly being treated as an economic development issue
The BOI has publicly emphasised the importance of sufficient power, clean-energy options and effective investment facilitation in attracting large-scale digital and high-technology investment. It has also indicated that it is coordinating with the Ministry of Energy and the ERC to strengthen electricity readiness for incoming investment, particularly in the Eastern region.
4. Direct PPA is increasingly being treated as an economic development issue
In May 20262, the BOI announced approvals for six major projects with a combined investment value of THB 958 billion, including three data centre and data-hosting projects with a combined investment value of THB 913 billion. In the same announcement, the BOI stated that power readiness and access to clean energy were increasingly important factors in attracting large-scale digital and high-technology investment, and identified Direct PPA as one of the clean-energy mechanisms being advanced.
4. Direct PPA is increasingly being treated as an economic development issue
This is significant because Direct PPA is no longer being considered solely as an electricity-sector reform. The policy discussion increasingly sits alongside questions of industrial competitiveness, digital infrastructure investment and long-term power-system planning.
5. Grid readiness is being addressed in parallel
The regulatory framework is not the only area evolving.
5. Grid readiness is being addressed in parallel
The BOI has stated that it is working with the ERC to accelerate power-infrastructure readiness for high-technology industries and data centres. The measures described by the BOI include the development of a “Power Map” intended to identify optimal zones, as well as the requirement for data centre projects to confirm electricity supply with the ERC before submitting BOI applications. The BOI has also outlined steps to strengthen electricity readiness with the Ministry of Energy and the ERC, focusing on urgent power-supply needs for incoming investment, particularly in Thailand’s Eastern region.
5. Grid readiness is being addressed in parallel
This highlights an increasingly important distinction: obtaining regulatory approval and obtaining physical delivery capability are not necessarily the same thing. As data centre demand concentrates in areas of strong investment interest, transmission and substation capacity may become as important to project implementation as Direct PPA eligibility and licensing requirements.
1. Move energy planning to the front of the project timeline
Electricity sourcing should now be treated as a first-stage project issue. Developers should assess power availability, network capacity and renewable-energy strategy at the same time as site selection and project design.
2. Budget for financial security and capacity commitments
With the financial-security requirement now approved in principle, large-scale facilities should factor this material financial commitment into development budgets and financing plans from the outset.
3. Assess the economics, not just the process
The principal area of uncertainty is now the tariff framework. Wheeling charges and other TPA service fees and, prospectively, Power Development Fund contributions, will all affect the delivered cost of electricity. The separate tariff class for data centre users approved in principle will also be a relevant benchmark against which Direct PPA economics are assessed. Once these charges are finalised, stakeholders will be in a better position to determine whether Direct PPA is a cost-competitive alternative to conventional electricity procurement.
4. Monitor tariff and regulatory developments closely
The tariff framework and related regulatory arrangements remain in development. Market participants should monitor these developments closely, as they are likely to affect project economics and investment decisions.
5. Consider location and grid availability early
Project location may increasingly influence access to electricity infrastructure. The growing emphasis on power-supply confirmation and the BOI’s Power Map initiative indicates that projects located in areas with suitable network capacity may hold a practical advantage as demand for electricity supply grows.
Regional comparisons: Singapore and Malaysia
Singapore is not a direct precedent for Thailand’s Direct PPA pilot. Singapore has a liberalised electricity market in which generation companies sell electricity in the wholesale market, retailers buy electricity from that market and compete to sell it to consumers, and separate entities perform market-support and grid-related functions. Nevertheless, one aspect of Singapore’s electricity market provides a useful comparison: transparency and predictability in the allocation of electricity-related costs. A key feature of Singapore’s electricity market is that participants can clearly distinguish between the energy cost of electricity and the regulated network-related charges layered on top of it, including use-of-system charges and market support service charges.
Regional comparisons: Singapore and Malaysia
Malaysia provides a closer regional comparison from a structural perspective. Its Corporate Renewable Energy Supply Scheme (CRESS) seeks to facilitate corporate access to renewable electricity through open access to the Peninsular Malaysia electricity supply network. Malaysia has also published CRESS guidelines, application process materials and system access charge materials, placing grid access and system charges at the centre of the commercial analysis.
Regional comparisons: Singapore and Malaysia
Taken together, the Singapore and Malaysia comparisons point to a practical lesson for Thailand: investors will need clear visibility over energy costs, network charges and other grid-related costs before they can properly assess Direct PPA arrangements.
Looking ahead
The broad architecture of Thailand’s Direct PPA pilot is now substantially clearer than it was at the beginning of 2026. Financial commitment requirements have progressed, electricity-planning considerations are being brought forward in project development, and Direct PPA implementation is increasingly being considered alongside wider questions of digital infrastructure growth, power availability and grid development.
Looking ahead
The principal remaining questions concern how the final economic and operational parameters will be structured and when the completed regime will be formally issued. Key developments to monitor include eligibility criteria and any capacity allocation for industrial users, the final data centre tariff, and the ERC’s amendments to the Power Development Fund rules.
Looking ahead
For many market participants, those developments will determine not only whether Direct PPA becomes a commercially attractive and bankable pathway for renewable-electricity procurement in Thailand, but also the extent to which Thailand can position itself as a competitive destination for energy-intensive digital and industrial investment.
