"As the backbone of Thailand’s power system, EGAT recognises that the global energy transition is both an urgent imperative and a strategic opportunity."

Thailand’s power sector is entering a pivotal phase of transformation. As the nation accelerates toward clean energy, the Electricity Generating Authority of Thailand (EGAT) is redefining its role to balance sustainability ambitions with energy reliability. In an exclusive discussion, Khun Narin Phoawanich, Deputy Governor – Fuel and Acting Governor of EGAT, shares the organisation’s strategies for leading a realistic and inclusive energy transition.

Shaping Thailand’s Long-term Energy Strategy

EGAT plays a pivotal role in shaping and implementing Thailand’s Power Development Plan (PDP), guided by national commitments to carbon neutrality by 2050 and net-zero emissions by 2065.

The organization supports the Ministry of Energy with real-time data and analytics as well as policy recommendations on future fuels, renewable integration, grid flexibility, and demand-side management to keep the PDP ambitious yet achievable. Its Renewable Energy Forecast Center (REFC) predicts solar and wind generation, while the Demand Response Control Center (DRCC) manages demand-side consumption.

“Insights from these centres enable precise modelling of renewable integration and infrastructure needs. This ensures grid stability, system reliability, and informed policy decisions,” Phoawanich says.

Through large-scale renewable energy projects, EGAT is demonstrating the economic and technical viability of clean energy. “These projects not only contribute directly to our renewable energy targets but also serve as a blueprint for further private sector investment,” he notes.

Key initiatives include large-scale hydro-floating solar projects, with 45 MW at Sirindhorn Dam and 24 MW at Ubol Ratana Dam, as part of a plan to deploy over 2,725 MW across nine major dams nationwide. EGAT is also piloting hydrogen at the Lamtakong Wind Turbine Project, where wind power operates an advanced electrolyser producing green hydrogen for a 300 kW fuel cell. This project generates operational data to support future hydrogen co-firing in main power plants. Additionally, EGAT is preparing for Small Modular Reactor (SMR) deployment by monitoring global advancements and building knowledge and partnerships for future readiness.

The “Triple S” Framework

EGAT’s strategies for a cleaner energy future are captured in the “Triple S” framework.

• Source Transformation focuses on expanding clean energy generation and pioneering next-wave technologies such as SMRs, hydrogen, and fuel cells.
• Sink Co-creation involves collaboration with industries, researchers, and communities on carbon sharing and carbon capture, utilisation, and storage (CCUS) solutions to drive a more sustainable and inclusive energy transition.
• Support Measure Mechanism encourages energy efficiency and demand-side management through programs such as Label No. 5 and initiatives managed by the DRCC.

These help to enhance system flexibility, investability, and reliability.

A Modernised Grid

Traditionally the country’s primary power producer and transmission utility, EGAT is now emphasising renewable integration and grid flexibility. From a centralised, fossil fuel-dependent model, the organisation is transforming into a more agile and diversified system that champions cleaner energy.

“This means we are no longer focused solely on generation, but also on facilitating integration of renewables and enhancing grid flexibility. This is to ensure that Thailand’s power system is the most reliable throughout the transition,” Phoawanich explains.

EGAT has invested in grid-scale batteries at Chai Badan (Lopburi) and Bamnet Narong (Chaiyaphum), along with pumped-storage hydropower at Vajiralongkorn and Chulabhorn Dams. Transmission upgrades and smart grid technologies are also underway to modernise the current infrastructure.

“We are also updating Power Purchase Agreements (PPAs) to manage renewable curtailment with clear rules and fair compensation,” Phoawanich explains further.

Nuclear – The Potential Game-changer

EGAT views SMRs as a strategic, long-term option to complement variable renewable energy.

“Among these, Small Modular Reactors are emerging as a potential game-changer, offering firm, low-carbon electricity that complements variable renewable energy sources like solar and wind. We believe that careful planning and staged development are crucial.”

The organisation is actively monitoring global advancements, conducting feasibility studies, and exploring regulatory, safety, and public acceptance frameworks to ensure readiness when deployment becomes viable.

Powering the Realistic Transition at Enlit Asia 2025

As a Host Utility at Enlit Asia 2025, EGAT highlights its theme, “Powering the Realistic Transition: Secure the World, Suitable for Everyone,” which covers three core areas:

• Clean Energy Project Development – Hydro-floating solar, hydrogen pilots, and SMR readiness.
• Power System Reliability – AI-managed grid through the REFC and DRCC, backed by 1,531 MW of pumped-storage hydropower.
• New Energy Services & Modern Infrastructure – Nearly 300 EV charging stations nationwide and Renewable Energy Certificates enabling businesses to meet sustainability targets.

“Powering the Realistic Transition” emphasises balancing clean energy ambitions with technical, economic, and system readiness, while “Securing the World” highlights EGAT’s role in ensuring grid stability, supporting cross-border power integration, and climate resilience. On the other hand, “Suitable for Everyone” underscores the commitment to an inclusive transition—ensuring affordability, accessibility, and fairness for all stakeholders.

These initiatives ensure long-term, carbon-free power without compromising reliability, with EGAT building a secure, sustainable energy system for both today and future generations.
