Mitsubishi reports leading GT market share in 2022
Mitsubishi Power achieved the highest stationary power generation gas turbine market share by megawatts in 2022, recording a share of 33% according to McCoy Power Reports data. The company is also estimated to have secured 49% market share in the ‘advanced class’ (G, H and J) gas turbine market, led by Mitsubishi Power’s JAC (J-series Air-Cooled) gas turbines. Cumulative Mitsubishi J-series orders had reached around 112 units as of mid July 2023 and in 2022 it received orders for 20 JAC machines, “contributing to the high market share.”
Mitsubishi Power notes that all of its heavy duty gas turbines “are now equipped with hydrogen co-firing capability”, able to operate on a mixture of up to 30% hydrogen and 70% natural gas, “which can be increased to 100% hydrogen in the future.” The J-series gas turbine, including the air-cooled JAC series, has surpassed two million operating hours, says Mitsubishi. A recent report from GlobalData (Steam and gas turbines market size, share and trends analysis by technology, installed capacity, generation, key players and forecast, 2021-2026) provides the estimates of 2021 power generation gas turbine and steam turbine market shares shown in the piecharts, right.

M701JAC gas turbines for Japan and Uzbekistan
Among recent orders received by Mitsubishi Power for its M701JAC gas turbines are three for combined cycle plants to be constructed in Japan and two for a combined cycle plant in Uzbekistan. For the Japanese project, a full-turnkey contract has been placed
by Chiba-Sodegaura Power Co (a company in which Tokyo Gas is an investor) for three 650 MW class natural-gas-fired combined cycle plants in Sodegaura City, Chiba Prefecture. A full-scope long-term service agreement (LTSA) has also been signed. The units will be brought into commercial operation progressively
from FY 2029 onwards. The Mitsubishi project scope includes EPC (engineering, procurement and construction), with Mitsubishi Power/MHI and Mitsubishi Electric working jointly. Mitsubishi Power/MHI is supplying gas turbines, steam turbines and heat recovery steam generators, while Mitsubishi Electric is supplying generators and other electrical equipment. The gas turbines being supplied will be capable of hydrogen co-firing and the plant will be designed so that it can be converted to 100% hydrogen firing with minimal rebuilding, says Mitsubishi Power. This project, according to Mitsubishi
Power, “will help to alleviate the power supply reliability issues that have occurred during Japan’s high-load periods in recent years,” and will contribute to Mitsubishi Power’s role as a “global pioneer in H2
power
generation.” The two M701JAC gas turbines to be supplied to Uzbekistan will be deployed at the 1600 MW class Syrdarya II natural gas fired GTCC facility. The equipment supply agreement has been signed with Harbin Electric International Company Limited, the Chinese contractor for the project.
Commercial operation is scheduled to for 2026. The power plant, located in the Syrdarya region about 150 km south
of Tashkent, will be built, owned, and operated by a project company, Enersok FE LLC, a joint venture of EDF, Qatari power company Nebras Power QPSC, Japanese trading company Sojitz Corporation, and Japanese energy firm Kyuden International Corporation. The electricity produced by the plant will be sold to Uzbek state-
owned power company JSC National Electricity Grid of Uzbekistan (under a 25 year agreement). The Uzbek government’s roadmap for achieving carbon neutrality in the power sector by 2050 calls for the development of a high- efficiency, low-carbon power generation infrastructure, with measures prioritising the replacement or modernisation of existing gas-fired power plants. This new Mitsubishi project will see an existing aged gas-fired steam
boiler power plant replaced with high-efficiency combined cycle. In addition to supplying two gas turbines to Syrdarya II, , Mitsubishi
Power says it will dispatch technical advisers to support installation and commissioning, and provide support for reliable operation under a long-term service agreement. Mitsubishi Power has received orders for 12 large frame gas turbines, including F and JAC-series, for seven projects in Uzbekistan, representing a market share for large frame gas turbines in the country of more than 80%, the company estimates. In addition, it has obtained a number of orders for its H-25 gas turbine for an urban distributed natural gas-fired cogeneration facility being developed in Tashkent.
