The collaboration between GCL SI and Getz Energy underscores a shared commitment to driving next-generation power solutions and supporting Thailand’s ambitious clean energy targets. The MOU specifically addresses the planned supply of photovoltaic modules, which will be instrumental in increasing the nation’s solar generation capacity. This partnership aligns seamlessly with GPSC’s long-term renewable energy strategy, further solidifying Getz Energy’s position within Thailand’s burgeoning clean energy market through utility-scale solar projects and intelligent energy management systems.

At the “Getz Energy Open House: Welcome to the Smart Energy Revolution” event, GCL SI showcased its cutting-edge module technologies. Among the featured products were the SiRo T Series NT12/66GDF module, alongside the SiRo B Series NR12R/66GDF and NR10R/54BGDF modules. Visitors were also given an in-depth look at GCL SI’s latest solar cell technologies and manufacturing prowess through displayed corresponding solar cells.

Designed with utility-scale and industrial applications in mind, the SiRo T series incorporates advanced TOPCon 2.0 technology. This series boasts bifacial power generation capabilities, enhanced operational stability, and remarkable long-term durability, ensuring reliable energy output even under challenging real-world operating conditions. Its optimized design makes it suitable for high-temperature environments and large-scale solar installations, promising stable and cost-effective performance throughout the lifecycle of a project.

The SiRo B Series, built upon GCL’s advanced GPC technology, offers a compelling combination of high conversion efficiency and superior visual integration, making it an ideal choice for premium distributed solar applications. This series features ultra-low reflectivity films, high-purity FBR granular silicon, and advanced passivation technologies, engineered to deliver robust performance while maintaining a refined aesthetic profile.

For Getz and GPSC, the flagship power and energy entity within the PTT Group, this 1GW PV modules deal is a crucial step in nurturing their renewable energy portfolio. Utility-scale solar power is identified as a cornerstone of the group’s long-term strategy for low-carbon energy generation. This initiative from GCL SI and Getz Energy not only supports Thailand’s renewable energy development but also strengthens GCL SI’s footprint in the broader Southeast Asian solar market.

The collaboration under the 1GW PV modules deal reflects GCL SI’s growing influence in meeting the regional demand for more efficient photovoltaic technologies, particularly those suited for large-scale solar applications. More broadly, this partnership highlights the significant and rapid expansion of utility-scale renewable energy development across Southeast Asia. This growth is propelled by increasing electricity demands, ongoing grid modernization efforts, and a collective drive towards decarbonization targets, all fostering substantial investment in next-generation solar infrastructure.

EGAT received government’s approval for the construction of the fourth unit at the power station in February 2011. The 800MW new combined cycle unit with over 57.3% efficiency started commercial operation in April 2014.

WANG NOI PROJECT HISTORY

EGAT began construction work on the Wang Noi CCGT power station in 1995 to meet the country’s surging demand for power. It was one of five large power generation projects EGAT began to meet domestic power demand which at that time was growing at about 12% (or 1,200MW) per year.

When first approved in July 1994, the project was planned as four combined-cycle power trains of 300MW each. The project was however modified to three combined-cycle power trains of 600MW each due to reasons related to the economy andfeasibility in transporting heavy equipment to the site. Two 200MW heavy-duty combustion turbine units with two heat recovery steam generators and a 200MW steam turbine generating unit are installed in each block.

The first two power trains for the Wang Noi power station were ordered in 1994, and unit one and two gas turbines were all on line by the end of 1996. Unit one steam turbine went on-line in September 1997, followed by the unit two steam turbine in November 1997. The official synchronisation of unit three gas turbines was completed by the end of 1997 and the third unit steam turbine was completed in April 1998. Total plant cost was just under $1.5 billion.

In September 1999, Wang Noi power plant became the first power plant in Thailand to receive ISO 14001 certification, assuring that its environmental management system is up to international standards.

The Wang Noi unit 4 was completed and handed over to EGAT by a consortium comprised of Siemens and Marubeni in April 2014.

The plant consumes over 280 million ft³ per day of natural gas, supplied from a gas separation plant at Rayong, owned by the Petroleum Authority of Thailand (PTT).

WANG NOI CCGT PLANT MAKE-UP

Mitsubishi Heavy Industries won the turnkey equipment supply contract for the initial units of Wang Noi. It had previously completed EGAT’s second largest CCGT installation, the 1,375MW Bang Pakong plant. US group Black & Veatch provided engineering services and Jurong Engineering, Singapore, won a mechanical and electrical works contract for the plant. Civil works were contracted to local Thai groups. Danish company KE Burgmann supplied expansion joints, insulation and other components to Mitsubishi Heavy Industries for the turbines.

A consortium led by Nichimen Corp, which also included GEA Thermal – Dynamic Towers Inc and Toyo-Thai Corp, was awarded a $3.8 million contract to supply and install cooling towers for the first phase of the Wang Noi power station. GEC Alsthom supplied and supervised the installation of seven 200t 250MVA 525/242-22kV transformers. This was part of a $23 million contract to supply 17 transformers to three EGAT power stations.

The newly built block-4 of the CCGT power station comprises of two SGT5-4000F gas turbines, an SST5-5000 steam turbine, and three SGen-1000A generators, all supplied by Siemens. The heat recovery steam generators (HRSGs), cooling tower, as well as the main transformers used at the plant were provided by Marubeni which was also responsible the civil works and erection of the new plant.

CHC Engineering was hired for the design and construction of the substation. Black & Veatch was awarded a subcontract by Marubeni to support design engineering and procurement for balance-of-plant equipment and other services for the fourth plant at Wang Noi.

FUEL SUPPLY

PTT awarded an Italian-Japanese consortium of Saipem and Mitsui & Co a $145 million contract to build a 154km-long pipeline from Ratchaburi power plant to Wang Noi. The 30in-diameter, high-pressure pipeline was completed in 2000 and allows PTT to supply Yadana gas to Wang Noi power station and other customers through its grid network.
