Site Readiness Assessment Framework

A preliminary investor-focused review of nine critical criteria shaping the development readiness of an integrated data center and power campus.

1.Land and Development Capacity

65 rai secured for Phase 1, with room to grow to 400 rai.

PADAENG Data Center Campus has secured 65 rai (25.70 acres) for Phase 1 in Smart Park Industrial Estate, Rayong. The campus can expand to 400 rai (158.15 acres) in total, giving hyperscale cloud, AI and HPC operators room to grow as demand increases. The master plan sets aside separate zones for data center development, shared utilities and future expansion, allowing additional phases to be developed while existing facilities remain in operation.

2.Zoning and Regulatory Framework

The PADAENG Data Center Campus is located in a designated industrial zone (purple zone) within Smart Park Industrial Estate in Thailand’s Eastern Economic Corridor (EEC). The project is being developed under the Industrial Estate Authority of Thailand (IEAT) Regulatory Framework. Land use, utility connections, and operating permits are subject to the requirements and procedures applicable to data center development and operations.

3. Fiber Connectivity

Fiber infrastructure is available within 30 km of the site, with four identified service providers: TOT, EGAT Telecom, Symphony, and Interlink. The proposed fiber-optic network will incorporate multi-carrier, dual-route connectivity to enhance resilience and redundancy. Final capacity allocation, route configuration, and commercial terms will be established with the selected carriers.

4.Power Availability and Resilience

600 MW power plan backed by written letters of support

The PADAENG Data Center Campus is approximately 800 metres from the Rayong 4 High-Voltage Substation. Planned grid connections at 115 kV and 230 kV are intended to support phased power delivery as the campus expands.

Written letters of support from public- and private-sector partners cover the following capacity:

- 300 MW from the Industrial Estate Authority of Thailand (IEAT)

- 200 MW from Global Power Synergy PCL (GPSC)

- 100 MW from Bangkok Cogeneration Co., Ltd. (BCC)



The final interconnection design, redundancy configuration, and power delivery schedule will be confirmed with the respective providers.

5.Water Supply and Management

The PADAENG Data Center Campus has a planned water supply of 40,000 m³/day, backed by written letters of support covering 20,000 m³/day from the Industrial Estate Authority of Thailand (IEAT) and 20,000 m³/day from Y.S.S.P.

The campus water plan includes pipeline infrastructure, ultrafiltration and reverse osmosis (UF/RO), and water reuse to support phased data center development. Final water allocations, dependable supply volumes, water quality standards, delivery infrastructure, and commercial terms will be confirmed through technical assessment with the relevant authorities and providers.

6.Environmental Conditions

Based on the project information available to date, no material environmental contamination has been identified at the PADAENG Data Center Campus site. A Phase I Environmental Site Assessment (ESA) will establish the site’s environmental baseline by reviewing historical land use, available soil and groundwater records, and potential environmental liabilities. The findings will inform detailed site planning and identify any areas that warrant further investigation.

7.Flood Risk and Site Resilience

The PADAENG Data Center Campus occupies a level 65-rai (25.70-acre) Phase 1 site within Smart Park Industrial Estate, Rayong. Preliminary project information indicates very low flood risk. Drainage forms part of the estate’s infrastructure plan, providing a basis for coordinating campus drainage from Phase 1. IEAT Smart Park infrastructure specifications

As the site lies outside FEMA flood map coverage, site-specific topographic surveys and hydrological studies will be used alongside the estate’s drainage data to verify the preliminary risk profile and set design requirements for finished floor elevations, drainage capacity, and flood protection for critical electrical systems and equipment.

8.Access and Logistics

The PADAENG Data Center Campus fronts Sukhumvit 16, the main road within Smart Park Industrial Estate, and connects to Sukhumvit Road (Highway 3) via the estate entrance. Nearby Map Ta Phut Port supports the delivery of oversized equipment to the campus, while U-Tapao International Airport provides convenient access for project teams.

9.Natural Hazard Exposure

Preliminary project information identifies the site as being outside Seismic Hazard Zones 3 and 4, indicating a low-to-moderate natural hazard profile. An independent multi-hazard assessment will establish the engineering design basis and resilience standards for seismic activity, severe storms, wildfire, and other relevant regional risks.
