USTDA awards grant to EGAT for pumped storage feasibility study in Thailand

6 April 2023


The US Trade and Development Agency (USTDA) has awarded a grant to the Electricity Generating Authority of Thailand (EGAT) for a feasibility study to support the development of a grid-connected pumped storage hydropower plant at the Vajiralongkorn Dam in western Thailand. 

If it goes ahead, the PSH plant would provide a long-duration, high-capacity energy storage option to support increased renewable energy integration and power system reliability in Thailand.

“This project is a perfect example of how the United States is helping Thailand meet its ambitious climate goals, not only by reducing emissions through clean energy generation, but also by ensuring the security of Thailand’s power system,” said US Ambassador to the Kingdom of Thailand Robert F. Godec.

According to USTDA Director Enoh T. Ebong, USTDA has a long history of partnering with EGAT on the development of Thailand’s energy infrastructure priorities. “Our support for this project reflects a shared goal of expanding renewable energy integration and reliability and promoting inclusive and sustainable economic growth,” said Ebong. “At the same time, this project will create opportunities for US solutions to be deployed in the development of the pumped storage hydropower plant.”

The new study will assess the technical and economic viability of the proposed plant, including a geotechnical and geological analysis of the project site, plant design, preliminary environmental and social impact assessment, risk assessment, cost and economic analysis and an implementation plan.

“Energy storage systems are an important part of our electrical infrastructure. They are used as a tool to support power system management, reduce fluctuations from renewable energy and support the country’s grid modernization development plan,” said Boonyanit Wongkrumit, EGAT’s Governor. “We’re thrilled that USTDA has chosen to support us along our journey and hope for a long and ongoing relationship. With your expertise and experience, EGAT believes that we will work together through our mutual cooperation to accomplish the project with a successful and satisfactory result to secure the stability and reliability of the power system.”

USTDA said it’s grant highlights its commitment to advancing the Indo-Pacific Economic Framework in collaboration with public and private sector partners across the region. The grant also supports the goals of the Partnership for Global Infrastructure and Investment to promote the implementation of clean energy infrastructure globally.
