New Hydrogen-Capable 600-MW Power Plant Orders GE Vernova H-Class Turbine

YTL PowerSeraya ordered GE Vernova’s 9HA.01 gas turbine for its planned, hydrogen-capable 600 MW combined-cycle power plant to be constructed in Pulau Seraya Power Station on Jurong Island, Singapore. POWERCHINA and SEPCO III join GE Vernova in executing an engineering, procurement, and construction contract to develop the plant, scheduled for operation by 2027. It will be GE Vernova’s first hydrogen-blended natural gas facility in Singapore.

“By 2027, we intend to expand our power generation capabilities in Jurong Island, Singapore with natural gas power technologies that are hydrogen-compatible to help meet the nation’s growing electricity needs and ensure energy security,” saidJohn Ng, Group CEO of YTL PowerSeraya. “Our collaboration with GE Vernova on the 600 MW hydrogen-capable project marks a milestone in Singapore’s journey toward a more sustainable energy future. This collaboration leverages the strengths of both companies. Together, we are laying the groundwork for a lower-carbon future, and this project is a step in advancing Singapore's energy transition and enhancing its energy resilience.”

The contract also includes the delivery of an STF-A650 steam turbine, W88 generator, and heat recovery steam generator equipped with triple pressure and reheat capabilities. The 9HA.01 gas turbine initially ran on natural gas but can now burn up to 50% by volume of hydrogen blended with natural gas. The company’s DLN2.6e combustion system is also installed on the 9HA.02 and 7HA.03, enabling high-content hydrogen combustion without diluent. This technology was developed under the Department of Energy’s High Hydrogen Turbine program, and, in addition, the H-class turbines can reach full combined-cycle plant load in less than 30 minutes.

“GE Vernova sees hydrogen-blended natural gas serving as a catalyst capable to accelerate the world’s efforts towards the path of decarbonizing the power generation sector,” said Ramesh Singaram, President and CEO, Asia of GE Vernova’s Gas Power. “We are pleased that YTL PowerSeraya selected our H-Class technology aiming to deliver efficient power generation that can emit less carbon when blended with hydrogen. We look forward to teaming with SEPCOIII and POWERCHINA to bring lower-carbon power generation to Singapore, in alignment with Singapore’s commitment to achieve a net-zero economy by 2050.”

GE Vernova also established its Global Repair Service Solution (GRSS) center in Singapore—a HA turbine repair and heavy-duty rotor service center. In addition, the GRSS conducts F-class bucket repair, F-class turbine blade repair, and aeroderivative repair services with combustor DVM coatings. In 2021, GE Vernova established the Advanced Manufacturing and Repair Technology center within the GRSS to bolster repair capabilities for its HA fleet.

GE Vernova’s Turbine Installments

Last week, Guangdong Energy Group’s Dongguan Ningzhou combined-cycle power plant entered operation in Guangdong province, China, with GE Vernova’s H-class technology. The plant is powered by three 9HA.02 gas turbines and is expected to add up to 2.4 GW of power to China’s national grid, in addition to the 1.34 GW of power already provided by the HA-equipped Huizhou power plant. The Dongguan Ningzhou project is aligned with China’s Greater Bay Area policy to focus on the coal-to-gas energy transition.
