State Development & Investment Corporation Power (SDIC Power) subsidiary SDIC Jineng (Zhoushan) has brought Unit 2 of its gas-fired combined-cycle power plant in Zhoushan, Zhejiang province, into commercial operation on August 31, 2026, following a 168-hour trial run, it is reported. The plant reportedly adopted GE Vernova’s large 9HA.02 gas turbines, with Harbin Electric Corporation supplying the package.
The plant was designed with a nominal capacity of 2×745MW, but the actual completed unit capacity is 848.31MW each, bringing combined capacity across Units 1 and 2 to approximately 1,696.6MW — a large gas-fired combined-cycle project. Unit 2 is the one that has entered commercial operation, adopting GE Vernova’s 9HA.02 gas turbines and reportedly signing a Long Term Service Agreement (LTSA) with GE Vernova to stabilize operations and maintenance.
Unit 2’s capacity is 848.31MW, and once the full complex (Units 1 and 2 combined) is in full operation, it is expected to generate up to 50.54 billion kWh annually. Carbon emission intensity is reported at about 40% of an equivalent coal-fired plant, reducing annual CO2 emissions by an estimated 2.49 million tonnes. Unit 2 completed its 168-hour trial run and began commercial operation on August 31, 2026, with the news disclosed on September 1, 2026.
Zhejiang province, on China’s eastern coast, is pursuing a power mix transition to reduce reliance on coal-fired generation and expand the share of gas-fired combined-cycle capacity linked to LNG import infrastructure, and this Zhoushan project is part of that effort.
The steady stream of large gas-fired combined-cycle project completions along China’s eastern coast shows that the shift from coal to gas power is becoming a substantive pillar of China’s power mix policy. The adoption of GE Vernova’s large gas turbines and the accompanying LTSA in this project illustrates that Western gas turbine manufacturers continue to remain competitive in the core equipment supply chain even for large Chinese power projects. However, the fact that package supply is handled by a domestic Chinese company such as Harbin Electric reaffirms the typical supply chain structure of Chinese power projects, in which core rotating equipment is sourced from foreign manufacturers while the remaining equipment and construction are integrated by domestic firms. The increase in gas-fired combined-cycle investment in coastal regions with good LNG terminal access, such as Zhejiang, is also an example of how expanded LNG import infrastructure supports a virtuous cycle of fuel transition in the power sector. The 848MW-class large single-unit capacity ranks among the largest in Asia and could serve as a design reference for similarly ultra-large gas-fired combined-cycle projects going forward.
The commercial operation start date for Unit 1 and the timing of full complex operation are the first points to confirm. How the LNG supply route (long-term contract or spot market) and fuel cost structure for this plant will be formed is also worth watching. In addition, whether similar large gas-fired combined-cycle projects will be awarded across Zhejiang and other eastern coastal regions of China, and how consistently Western gas turbine manufacturers such as GE Vernova continue to win orders in the Chinese power market going forward, also bear watching.
