Thailand’s Energy Sector Embraces Innovation for a Sustainable Future
Thailand’s energy sector is undergoing a significant transformation, driven by the need to balance immediate economic demands with long-term environmental and social responsibilities. As the country progresses in its development goals, there is a growing emphasis on energy policies and innovations that ensure stability, resilience against global uncertainties, and sustainability at the core. This vision not only secures reliable energy for today but also lays the foundation for a cleaner, more sustainable future, supporting Thailand’s growth while aligning with global efforts to combat climate change.
A key initiative in this journey was the ‘Show and Share Innovation for the Better Life 2025’ event, co-hosted by the Electricity Generating Authority of Thailand (EGAT), the Metropolitan Electricity Authority (MEA), and the Provincial Electricity Authority (PEA). Held on 18 August 2025 at the Bangkok Convention Centre, Centara Grand at CentralWorld, the event brought together innovators, policymakers, researchers, academics, and members of the public to explore groundbreaking energy solutions. These innovations aim to address the challenges of the digital energy era and the global shift towards a low-carbon society.
The event featured exhibitions of outstanding projects from each organization, as well as a panel discussion on the theme ‘Innovation for Power System Security.’ The session, moderated by media personality Pongsuk Hiranprueck, aimed to inspire the next generation of innovators to design solutions that contribute to Thailand’s sustainable future.
Modernizing the Electricity Grid
Speaking at the seminar on behalf of EGAT, Mr Warit Rattanachuen, Assistant Governor for Research, Innovation and Business Development, outlined the authority’s commitment to modernizing Thailand’s electricity grid. Key initiatives include upgrading the grid for greater resilience, introducing flexible power purchase agreements, and deploying large-scale energy storage systems, both battery-based (BESS) and pumped-storage hydropower plants.
EGAT has also established a Demand Response Control Centre (DRCC) and a Renewable Energy Forecasting Centre (REFC) to enhance system planning and operational efficiency. In addition, the authority is rolling out multiple sustainability projects, from Renewable Energy Certificates (RECs) and floating solar farms to EV integration through the EleXA and BackEN EV platforms, as well as urban mining initiatives for battery recycling.
Groundbreaking Innovations
Among the most notable innovations showcased at the event was EGAT’s new method for stringing high-voltage transmission lines across 115-230 kV equipment without shutting down the grid. Traditionally, such operations required power interruptions, risking outages and economic disruption. With this breakthrough, EGAT engineers can safely maintain and install conductors, OPGW, and OHGW while keeping electricity flowing.
“The inspiration came from the idea of working without shutting down the power,” explained Mr Chaiwat Somno, one of EGAT’s innovators behind the project. “In provinces like Chiang Mai and Lamphun, electricity demand is very high. We wanted to create a solution that allows us to carry out maintenance and stringing work while keeping the lights on, ensuring people and businesses continue to have reliable power without disruption.”
The benefits of this innovation are significant: reduced need for power outages, improved safety, and minimized sagging risks during installation. Most importantly, the innovation prevents massive opportunity losses. For instance, avoiding shutdowns on a 230 kV line can prevent up to 360 MW of lost capacity, equivalent to an economic impact of more than 31 million baht per hour. This solution not only strengthens Thailand’s power system resilience but also exemplifies how home-grown innovation can safeguard the country’s energy security.
Other EGAT innovations showcased at the event included unmanned underwater vehicles for monitoring hydro-floating solar projects, AI-enhanced UAV inspections for solar farms, and an online fire alarm monitoring system.
MEA and PEA Highlight Their Contributions
In addition to EGAT’s highlights, MEA and PEA also displayed practical tools and solutions developed by their teams. MEA presented innovations such as a hydraulic cable cutter, an H-V cable nut tightening tool, and a plug-and-play meter box, while PEA demonstrated devices including a mounting base for cutting concrete poles, guy wire wrapping tools, and high-voltage substation contact cleaning equipment.
MEA emphasized its commitment to developing innovations that ensure both reliability and sustainability in the urban electricity system. Examples include replacing traditional wiring materials with safer alternatives, developing circuit breaker and insulation equipment that can be installed without power shutdowns, and introducing steel monopoles to mitigate the risk of pole collapse.
MEA has also advanced the deployment of Smart Meters and Transformer Load Monitoring (TLM) systems to improve efficiency in energy management. Another milestone innovation is the Modular Substation with Net Zero capability, which integrates solar power with energy storage systems (ESS) to minimize external electricity use and reduce carbon emissions.
PEA’s Focus on Carbon Reduction
Mr Somchai Songsiri, PEA’s Assistant Governor for Planning and Engineering (Planning and Power System Development), highlighted the organization’s innovation roadmap and its alignment with the strategic policy PEA MOVE. At the forefront is CARBONFORM, a platform that helps organizations assess greenhouse gas emissions and supports both internal and external clients in achieving carbon reduction and offset targets.
PEA is also implementing Microgrid projects in energy-critical areas to enhance local electricity reliability, as well as piloting Third-Party Access and Energy Trading Platforms to promote clean energy trading. To ensure sustainability, PEA has set out a long-term vision that positions itself as an innovation-driven organization dedicated to delivering clean energy and smart energy management solutions to customers nationwide.
A Collaborative Effort for the Future
The Show and Share Innovation for the Better Life 2025 event marked an important milestone in the collaboration between Thailand’s three electricity authorities. By combining research, development, and creative problem-solving, EGAT, MEA, and PEA are not only responding to today’s challenges but also preparing the nation for tomorrow’s low-carbon, digitally connected energy future.
As Thailand navigates its energy transition, such initiatives demonstrate that innovation is not just about technology, but also about empowering people, supporting economic growth, and building a sustainable society for generations to come.
