Mitsubishi Power Equips GTCC Power Plant with M100S Gas Turbine

Mitsubishi Power will deliver a 100-MW gas turbine combined-cycle (GTCC) power plant, driven by a M100S small- to medium-sized gas turbine, for Jiangsu Lihuai Steel’s plant in Huai’an City, China. The M100S turbine fires blast furnace gas (BFG) and will be deployed as a core component of the GTCC plant. Jiangsu Lihuai Steel will begin GTCC operation in 2027, with the turbine and related equipment manufactured and supplied by Takasago Machinery Works and other equipment procured by Dongfang Turbine Co. The company will dispatch technical advisors for installation and commissioning.

The M100S combines technology for BFG-fired large-scale turbines with technology for natural gas-fired JAC gas turbines, boasting high performance and reliability. In a combined-cycle setting, the M100S power plant has a 100-MW output and is smaller and more efficient than traditional models. Byproduct gas from blast furnaces, coke ovens, and converters will be used as fuel. BFG has a lower calorific value than natural gas and other fuels, so advanced technology is needed to achieve stable BFG combustion in gas turbines.

Also, the turbine offers flexibility to fluctuations in gas volume and responds quickly to load fluctuations in the steel plant. BFG-fired gas turbines reduce environmental impacts, comply with air regulations, and efficiently use byproduct energy from the steel plant. It may serve as a replacement for conventional small-sized boiler, turbine, and generator power plants typically deployed in the Chinese steel industry.

Mitsubishi Power developed the M100S model to respond to growing demand for energy efficiency and decarbonization from China’s steel industry. This represents the first order for the M100S, and Mitsubishi Power’s market share for BFG-fired gas turbines exceeds 60%. Jiangsu Shagang Group already installed five gas turbines manufactured by Mitsubishi Power, attempting to replace existing BTG power plants due to their limited power generation capacity and low efficiency. China’s primary steelmakers are seeking 100-MW models to replace their current assets and, up to now, power generation in this range have been limited to BTG power plants.

Tung Hsiao Power Plant

In September 2025, the Taiwan Power Co. granted Mitsubishi Power and CTCI Corp. a $5.2 billion contract to execute a full turnkey project at its 2,800-MW Tung Hsiao power plant in Miaoli County, Taiwan. Mitsubishi Power will deliver five units with M501 JAC gas turbines, steam turbines, and auxiliary equipment, while CTCI performs engineering, procurement, and construction and balance-of-plant work for the GTCC project.

The five new turbine units will begin operation sequentially from 2030 to 2031, with generators supplied by Mitsubishi Generator Co. Several GTCC power plants, updated in the renewal’s first phase and located near the new facility, are equipped with three M501 JAC units operating since 2018. These units arrived following a joint contract awarded to Mitsubishi Power and CTCI in 2013.

Taiwan Power’s Tung Hsiao plant is located approximately 130 km southwest of Taipei and based on Taiwan’s long-term power supply and development plan, it will replace existing power plants once renewal work is completed. The renovation aims to increase power generation capacity and reduce environmental impact, while meeting the region’s rising industrial and residential electricity demand. In addition, the project also helps Taiwan in meeting its net-zero emissions goal.
