Thailand Renewable Energy Pipeline Draws Up to US$2.61bn in Investment 

Thailand’s ERC has licensed 449 renewable power projects totalling 1,607.58 MW, led by solar, waste-to-energy and biomass investment.
Thailand’s renewable power pipeline is gathering pace, with 449 projects licensed by the Energy Regulatory Commission (ERC) and investment expected to reach up to US$2.61 billion.

The expansion comes as businesses and industries respond to the global energy transition and evolving international trade and sustainability standards. Renewable power is increasingly being used to strengthen energy security, reduce electricity costs and support long-term competitiveness.

According to data collected by the ERC from 2024 to the present, licences have been issued for 449 renewable electricity projects that are either under development or construction. Together, they represent 1,607.58 megawatts of capacity and are expected to generate total investment of around US$2.10 billion to US$2.61 billion.

Solar dominates new renewable investment

Solar power accounts for the largest share of the pipeline, with around 400 projects.

These include 386 solar rooftop projects with combined installed capacity of about 587.30 megawatts and 14 solar farm and floating solar projects with combined installed capacity of 562.83 megawatts.

Based on average investment of US$592,000 to US$740,000 per megawatt, the solar portfolio alone is expected to draw at least US$681.08 million to US$851.35 million.

Major players include WHA Solar, under the WHA group, which has 12 solar rooftop projects with combined capacity of 45.155 megawatts. The projects mainly cover warehouse and large industrial factory rooftops in industrial estates.

Gulf1, under Gulf Development, has 11 projects in progress with total capacity of 33.631 megawatts. These consist of nine solar rooftop projects totalling 23.791 megawatts and two ground-mounted solar farms totalling 9.840 megawatts.

Gulf MP WHA1, a joint venture between Gulf and WHA, is also building five solar rooftop projects with combined capacity of 26.170 megawatts.

B.Grimm’s activity includes Insee B.Grimm Solar, which has four projects under development with combined capacity of 69.415 megawatts. Three are ground-mounted solar farms totalling 63.04 megawatts, while one rooftop project accounts for 6.375 megawatts. The electricity will supply Siam City Cement.

Amata B.Grimm Power Service has another four projects under development with total capacity of 7.125 megawatts, including three rooftop projects totalling 6.025 megawatts.

Gunkul Engineering has positioned itself in southern Thailand, with three solar farm projects representing combined capacity of 176.60 megawatts, as well as solar rooftop projects.
