Thailand builds the world’s largest floating solar

Thailand creates world’s biggest solar farm - but not everybody is happy about it.

In Thailand’s northeastern province of Ubon Ratchathani, a reservoir has been transformed into a shimmering network of solar panels - capable of reducing the kingdom’s carbon emissions by 47,000 tonnes every year.

Touted as the "world's largest floating hydro-solar farm”, the Sirindhorn dam project is capable of creating solar power by day and hydropower by night.

The 720,000 square metre installation is the first of 15 farms Thailand plans to build as part of its ongoing commitment to reach carbon neutrality by the year 2050.

"This is the first and biggest project like this in the world," says Prasertsak Cherngchawano, Thailand’s deputy governor of electricity.

“There are 144,000 solar panels here. One panel is two square metres, and the whole farm is equivalent to 70 football fields."

The Southeast Asian country is stepping up efforts to wean itself off fossil fuels after Prime Minister Prayut Chan-O-Cha committed to achieving net-zero greenhouse gas emissions by the year 2065.

Alongside other world leaders at COP26 in Glasgow, Chan-O-Cha stated his intention to “ramp up measures in tackling climate change in any way imaginable.”

A green shift

Currently, only 11 per cent of Thailand's power comes from renewables and hydropowerAFP


Hitting these ambitious targets will require a major revamp of Thailand’s power industry.

The nation is still heavily reliant on fossil fuel, with 55 per cent of its energy derived from natural gas as of October 2021. This contrasts sharply with just 11 per cent stemming from renewables and hydropower, according to the Energy Policy and Planning Office (EGAT).

EGAT plans to produce 2,725 megawatts of power from floating hydro-solar farms by the year 2037 - over 30 per cent of the nation’s annual power needs.

But as the kingdom’s green revolution gets underway, many people are sceptical of the scheme.

The €32 million Sirindhorn project took nearly two years to build - with numerous delays resulting from solar panel delivery issues and technicians falling sick.

Locals have also expressed concern, claiming the farm has forced them out of areas traditionally used for livelihood.

"The number of fish I can catch has reduced, so we have less income," says Thongphon Mobmai, a local fisherman from the region.

"We also have to travel longer routes when we're out fishing and we can only drive our boats in areas designated by the authorities. These are the problems we have with the solar farm.”

Despite this, the electricity generating authority insists the project will not affect agriculture, fishing or other community activities.

"We've used only 0.2 to 0.3 per cent of the dam's surface area. People can make use of lands for agriculture, residency and other purposes," says Cherngchawano.

As well as generating power, officials hope the giant farm will also prove a draw for tourists. A 415-metre long ‘Nature Walkway’ has now been installed beside the dam, providing panoramic views of the reservoir and its floating solar cells.

More about the topic

The growing popularity of floating solar photovoltaic (FPV) installations raises specific issues regarding the development and the operation of these floating assets. DNV has vast knowledge of this technology from across the globe and combines its existing strengths in the solar energy and maritime industries. Our goal is to help you meet the challenges of this new and interesting solar discipline.

Our service offering includes:

  • Guidelines and tools for developers
  • Technology qualification, review and verification for floating structures
  • Bankability assessment
  • Feasibility assessment
  • Construction support
  • Technical due diligence
  • Technical advisory services
  • Risk assessment
  • Owner’s engineering and independent engineering
  • Tendering support
  • Energy production assessment
  • Environmental and social impact assessment
  • Material integrity and durability assessment
  • Modelling and simulation
  • Market study
  • Monitoring and asset management
  • Failure analysis

Our experience with this relatively new technology spans multiple continents. Here at DNV, we are keen to help you harness the energy generation potential that your specific geographic locations can offer floating solar technology. We have supported customers on more than 2 GW of floating solar projects at different stages of the project lifecycle including feasibility, construction and operation. We have been the technical advisor for the largest floating PV project in the world, located in the Asia-Pacific region. DNV has also spearheaded a Joint Industry Project involving 24 floating solar industry leaders to develop the world’s first Recommended Practice on the design, development and operation of FPV systems.

Floating solar has huge potential in areas where difficult terrain, land scarcity and competition for land may pose challenges to the development of ground-mounted solar systems. While available land has been used heavily in the past decades for the installation of solar plants, the available water surface still remains largely untouched. The combination of economic activities in water bodies, such as lakes, reservoirs, hydro dams and canals, with power generation that requires no additional surface space is making the business case for floating solar extremely attractive.

Compared to traditional ground-mounted and rooftop solar, the development of floating solar plants presents different challenges due to hydrodynamic loads on the structure, risk of corrosion and additional components to be designed, installed and maintained, such as the floats, the anchors and the mooring lines. These challenges are highly dependent on the location, size, type of water body, type of structure and environmental conditions. Performing a site-specific design and assessment will help to reduce risks for new and operating floating solar projects.

We are well-positioned to advise on any issue or challenge related to the design, development and operation of floating solar plants. Thanks to our long-lasting history, both in renewables and in offshore structures, we have a holistic skillset and comprehensive experience to address the challenges of this exciting and promising solar application.
