Thailand Accelerates Clean Energy With Solar And Wind Initiatives

Thailand is rapidly transforming its energy landscape, aiming to make electricity more affordable while advancing its clean energy goals. The nation has introduced the “Quick Big Win” initiative, a fast-track national policy designed to lower energy costs and increase income for households and farmers. Central to this initiative is the Solar-Powered Water Pumping Project for Agriculture. Over 1,200 systems have been installed across Thailand, supporting more than 700,000 rai of farmland. These pumps allow farmers to irrigate their fields free of cost throughout the year, resulting in savings of up to 15,000 baht per household annually. At the same time, this project reduces over 600,000 tons of carbon dioxide emissions each year, showcasing how renewable energy can benefit both people and the environment.

Another significant aspect of Thailand’s renewable push is the Community Solar Farm Programme. More than 300 communities are now able to generate electricity from solar power and sell it directly to the state. This initiative generates over 3 billion baht in local revenue annually while cutting greenhouse gas emissions by 800,000 tons per year. The program is inclusive, allowing households to participate even if they do not own farmland. Individual households can install rooftop solar panels, leading to monthly electricity savings of 800 to 1,500 baht. Additionally, participants can claim tax deductions of up to 200,000 baht, collectively saving over 585 million units of electricity annually and preventing an additional 280,000 tons of CO₂ emissions.

Thailand is also exploring innovative energy solutions such as the Hydro-Floating Solar Hybrid Project by EGAT. This project combines solar and hydropower, creating a 1,600-megawatt system that lowers national energy costs and cuts emissions by 800,000 tons per year. These initiatives are part of a larger plan to transition the country toward carbon neutrality by 2050 and net-zero emissions by 2065 or earlier, in line with Thailand’s new Power Development Plan. The plan is expected to attract over 700 billion baht in investment and create tens of thousands of jobs, highlighting the economic benefits of the renewable energy transition.

From a cost perspective, renewable energy is becoming increasingly competitive in Thailand. By 2022, the levelized cost of electricity (LCOE) for new utility-scale solar plants became cheaper than both new combined-cycle gas turbines and coal-fired power plants. By 2024, solar power will also prove more cost-effective than the short-run marginal cost of existing coal and gas plants. Projects combining solar with storage have become economically competitive with the operational costs of thermal power plants, while onshore wind energy is expected to become cost-competitive with new coal plants, despite limited suitable locations due to low wind speeds.

Thailand’s Gas Plan 2024 proposes blending natural gas with 5% clean hydrogen by 2030. However, studies suggest that direct use of solar and wind energy is far more cost-effective for decarbonizing the power sector. By scaling up renewable energy, solar and wind could provide up to 60% of Thailand’s electricity by 2050. This strategy not only reduces emissions but also enhances energy security, offering a sustainable and economically viable pathway for the country’s clean energy future.

The combination of national policies, community programs, and innovative technology demonstrates Thailand’s commitment to making renewable energy accessible, affordable, and impactful. Every solar rooftop, floating panel, and community farm contributes to a cleaner, more resilient energy system while benefiting households, farmers, and the nation as a whole.
