Thailand Approves 746 Billion Baht in Data Center Investments for 2025 - Southeast Asia's Largest Digital Infrastructure Capital Flow
Thailand's Board of Investment (BOI) closed 2025 with a record package of approvals worth 1.87 trillion baht, of which 746 billion baht went to data center projects. TikTok's (ByteDance) multi-site program received approval for 842 billion baht to deploy servers and infrastructure in Bangkok, Samut Prakan, and Chachoengsao. The total capacity of projects in the pipeline reached 2.87 GW. Microsoft announced investments exceeding $1 billion in cloud and AI services for the 2026-2028 period, Google launched a cloud region in Bangkok with a projected economic impact of 1.4 trillion baht over five years. The geographic focus has shifted to the Eastern Economic Corridor (EEC) - Chonburi, Rayong, and Chachoengsao provinces, which concentrate up to 70% of new capacity.
Why Data Centers Choose the Eastern Seaboard
The Eastern Economic Corridor received priority zone status with tax incentives through BOI. Data center operators are exempted from corporate income tax for up to eight years for highly efficient facilities (assessed by PUE and water consumption metrics) and five years for others, within the limits of 100% of the investment amount. Import duties on equipment are zeroed out, full foreign ownership is permitted without the need for a Thai partner.
Chonburi province is located within a 30 km radius of three airports - Don Mueang, Suvarnabhumi, and U-Tapao. The high-speed rail linking these hubs transforms the Bangkok - Chonburi - Rayong corridor into a single agglomeration with travel times up to 45 minutes. The Electricity Generating Authority of Thailand (EGAT) has launched multi-billion baht grid modernizations to provide data centers with stable power supply. Regulators are testing direct Power Purchase Agreements (PPA) with third-party grid access, allowing operators to directly contract renewable generation. The pilot framework is designed for 2000 MW.
Who's Already Building and How Much It Costs
In November 2025, BOI approved four projects with a total value of 100 billion baht and combined IT load of 376 MW. Skyline Data Center received permission to build a 200 MW facility in Chachoengsao for 46 billion baht. Joint venture GSA (Gulf Energy, Singtel, AIS) launched a 35 MW project in Chonburi worth 13.5 billion baht with scaling potential to 90 MW and liquid cooling readiness.
In January 2026, BOI approved seven more projects worth 96.9 billion baht. True Internet Data Center received approval for three facilities with total capacity of 223 MW (45.3 billion baht), GSA Data Center - for two projects with IT load of 120 MW (37.2 billion baht). Singapore hosting company Freyr Technology is investing 6.3 billion baht, Stellar DC - 8.1 billion baht.
Data center construction costs range from $7 to $10 million per megawatt of installed capacity. Each large facility creates between 200 and 500 jobs for engineers, technicians, and management personnel.
How This Affects Land Prices and Commercial Real Estate
Industrial and technology real estate near power hubs and fiber optic highways is appreciating 10-15% annually. Land plots within 20 km of major EGAT substations in Chonburi province have risen 18-22% over two years. Average rental rates for class A industrial space in Chonburi and Rayong zones increased 12% over the past 12 months, according to CBRE Thailand.
Data centers generate demand for physical space: server halls, cooling systems, office blocks, logistics areas for equipment. Each major project requires 15,000 to 50,000 sq. m of buildings and adjacent infrastructure. Operators purchase industrial plots in Chonburi, Rayong, and Chachoengsao through long-term leases (30+30 years leasehold) or Thai companies. Entry threshold is 15 to 20 million baht (approximately $430-570 thousand) per plot.
Residential Real Estate: Who Rents Apartments Near Data Centers
Each data center creates an ecosystem around it. Engineers and management staff rent housing within a 15-30 km radius of the facility. In Si Racha and Laem Chabang districts, condominium rental rates have risen 12-18% over the past year. Satellite cities around technology facilities are growing according to the Silicon Valley model: demand for studios and one-bedroom apartments is consistently high, lease contracts are concluded for one to three years.
Purchasing condominiums or townhouses in Si Racha, Pattaya, and Laem Chabang for rental to technology company employees yields 7-9% annually in baht, higher than the 4-6% from resort properties. Vacancy risk is lower, contracts are longer, anchor tenants are international corporations. Entry threshold is 3 to 5 million baht ($85-145 thousand) for a studio or one-bedroom apartment.
Real Estate Investment Trusts (REITs) Include Digital Infrastructure in Portfolios
Thai Real Estate Investment Trusts (REITs) traded on the Stock Exchange of Thailand (SET) have begun including digital infrastructure assets in their portfolios. Digital Telecommunications Infrastructure Fund (DIF) is one of the region's largest infrastructure funds with capitalization exceeding 100 billion baht. Dividend yields of such funds are 5-7% annually. For investors not ready to buy land or buildings directly, REITs offer a liquid instrument with transparent reporting and asset diversification.
Legal Restrictions for Foreigners and Ways Around Them
Foreigners cannot own land in Thailand directly, but through a Thai company (subject to legal requirements) or long-term lease (30+30 years leasehold) it is achievable. Special conditions apply in EEC zones: right to 49-year lease for foreign investors. Buildings and structures on leased land can be purchased in full ownership (freehold).
When purchasing a plot or building in an industrial zone, request Environmental Impact Assessment (EIA) permit, BOI license, confirmation of connection to EGAT power grids. Work with a lawyer specializing in industrial real estate. Due diligence includes Land Office inquiry about land status (Chanote, Nor Sor 4), absence of encumbrances, and zoning compliance.
Yield Comparison: Industrial Technology Parks vs Resort Real Estate
| Asset Type | Annual Yield (baht) | Average Lease Contract | Vacancy Risk | Entry Threshold |
|---|---|---|---|---|
| Industrial Technology Park (EEC) | 7-9% | 3-10 years | Low | 15-20 million baht |
| Condominium for Data Center Employees | 7-9% | 1-3 years | Low | 3-5 million baht |
| Resort Condominium (Pattaya, Phuket) | 4-6% | 6-12 months | Medium | 2-4 million baht |
| REIT with Digital Infrastructure | 5-7% (dividends) | - | Low | From 10,000 baht (1 unit) |
Industrial assets show higher yields and stability due to anchor tenants - international technology corporations. Resort real estate depends on tourist season and demand fluctuations.
What This Means for Buyers in Pattaya
Pattaya is 40 km from the epicenter of data center construction - Si Racha and Laem Chabang. High-speed rail reduces travel time to 25 minutes. Technology company employees working in Chonburi and Rayong choose Pattaya for residence due to developed infrastructure, international schools, hospitals, and leisure.
Demand for long-term rentals in Pattaya is growing. Condominiums in Pratumnak, Jomtien, and Naklua areas, oriented toward expats, show 85-90% occupancy year-round. Tenants are not tourists, but professionals with contracts from one year. This reduces seasonality and increases income predictability.
For investors from Russia accustomed to the resort model, this is an alternative strategy. Purchasing a two-bedroom apartment in Pattaya for 4-6 million baht for rental to data center employees yields 6-8% annually in baht with minimal vacancy risk. Contracts are concluded directly with employers or through corporate agencies, eliminating payment issues.
Investment geography is changing. While previously main interest was concentrated on the coast, now it's worth studying the Bangkok - Chonburi - Rayong corridor. If planning an inspection trip to evaluate properties, consider hotels in Si Racha or Laem Chabang - that's where new technology parks are located and infrastructure is easy to assess.
Risks and Planning Horizon
Land prices in EEC have already risen 18-22% over two years. Growth potential persists, but entry is worthwhile only with clear understanding of the transaction's legal structure and a five-year+ horizon. Data centers require stable power supply - if the grid cannot handle the load, some projects may be delayed. EGAT announced modernizations, but implementation will take time.
Regulators are testing direct PPAs with third-party grid access, but the pilot framework is limited to 2000 MW. If demand exceeds infrastructure capabilities, operators will compete for connection, which could delay facility launch timelines and reduce land price growth rates.
For residential real estate buyers in Pattaya, risks are lower. Demand for long-term rentals from technology company employees is already established, city infrastructure is ready to accept new residents. The key is choosing properties with good transport accessibility to Chonburi and Rayong (no more than 50 km) and focusing on the 3 to 6 million baht segment per apartment, where demand is most stable.
