Solar energy development is the backbone of IES. As innovators and pioneers who approach every situation from a unique angle, we have taken solar energy generation to the next level. Dedicated to harnessing this natural resource to its fullest potential – exploring every viable method and solution.

IES successfully completed the 84 MW Lopburi Solar Project from the ground up. The development is one of the largest solar projects in the world and the first utility-scale solar energy project in Thailand. Our industrious team was crucial to the success of this groundbreaking venture. From site surveys to the final execution of power delivery – even building the plant and the very power lines that connected it to the grid. The project not only sealed our reputation as dynamic sustainable energy developers, it showed the world our dedication to local people and communities.

We are at the forefront of developing renewable energy in Thailand and are dedicated to effectively providing sustainable energy solutions to all. IES has numerous ongoing solar energy projects in Bangkok, Thailand and several prefectures in Japan.


IES recognizes wind power as an important resource and has made great strides in developing a sustainable project in the southern region of Laos. After three years of intensive feasibility studies, IES chose to establish this cooperation with the Government of Laos in order to be on the ground level of the country’s 21st century development. Such sustainable and low-impact developments will lay a strong and clean foundation for Laos’ future. And in accordance with the company’s values and mission, IES’ wind energy projects do not uproot local residents and have little impact on their livelihood in agriculture.

The 600 MW Monsoon Wind Power Project with Government of Laos (GOL) is a groundbreaking venture that will be developed in two distinct phases, culminating in 2021. It is poised to be ASEAN’s largest wind farm. The very site it rests upon was carefully surveyed, with cooperation from a reputed international technical advisory firm, and selected for its advantageous location, attributes and potential to contribute to the local community.

One of the goals set out for this project is to incur no fuel costs and minimum operating costs, all without re-settling or disrupting the local villagers. Furthermore, part of the community initiative is the clearing of dangerous areas that are riddled with landmines. It has been forecasted that this project is poised to play an important role in supporting the ASEAN Power Grid Policy.


IES expertly utilizes local resources in biomass development.

The rubber industry is one of the largest industries in the south of Thailand, with the number of rubber plantations increasing annually. After its life cycle of 25 years, rubber trees can no longer be tapped for latex and must be cut down and replanted for sustainable natural rubber production. This initiative is further encouraged by the Rubber Authority of Thailand (RAOT) and the Thai Hevea Wood Association (THA).

While rubber has been planted primarily for agricultural uses, the rubber plant itself produces quality timber widely used in the wood industry. By discovering the abundantly available resources added with growing demands in international markets for biomass fuels, IES sees the opportunity to add value to rubber wood scraps by transforming them into woody biomass fuels, ensuring that our quality exceeds international standards, and establishing trade across international markets.

Through harnessing the value of excess natural resources, IES demonstrates complete awareness of environmental sustainability while equally stimulating the local economy.
