The Asian Development Bank approved a $350 million financing package on February 19, 2026, for three solar power projects with battery storage in Thailand. The projects aim to strengthen grid flexibility and support the country’s renewable energy integration as solar capacity expands.
KEY FACTS AT A GLANCE
- $350 million financing package approved by the Asian Development Bank
- Three solar power projects located in central Thailand
- 126 MW of solar capacity paired with 151 MWh of battery energy storage
- Additional 68 MW solar project included
- Developed in partnership with Gulf Renewable Energy Co., Ltd.
- Announcement date: February 19, 2026
The Asian Development Bank announced on February 19, 2026, that it had approved a $350 million financing package to support three solar power projects in Thailand incorporating battery energy storage systems. The projects are being implemented in partnership with Gulf Renewable Energy Co., Ltd., a subsidiary of Gulf Energy Development Public Company Limited.
The financing will support 126 megawatts (MW) of solar generation capacity integrated with 151 megawatt-hours (MWh) of battery energy storage systems, along with an additional 68 MW solar power project. The battery systems are designed to store electricity generated during peak solar production periods and discharge it when needed, helping to stabilize grid operations and manage supply variability.
The projects align with Thailand’s efforts to expand renewable energy generation capacity while maintaining grid reliability as more variable resources are connected to the power system. The financing package reflects continued multilateral support for clean energy infrastructure across Southeast Asia. Publicly available details remain limited to the official announcement.
