Mitsubishi Power projects in Uzbekistan, Singapore and Taiwan
Current Mitsubishi Power projects include a new combined cycle plant at the Talimarjan TTP (thermal power plant) site in Uzbekistan, upgrade of M701F gas turbines in Singapore, and supply of an H-25 gas turbine to a combined heat and power plant in Taiwan.
Mitsubishi Power’s scope at Talimarjan consists of two M701F gas turbines, two steam turbines, and auxiliary equipment, with commercial operation of the new facility scheduled for 2025. Mitsubishi Power’s client for the project is Spanish engineering firm Intecsa Ingenieria Industrial.
It is Mitsubishi Power’s second order for main components at Talimarjan TPP, having received an order for two M701F gas turbines plus generators for Talimarjan TPP unit 1 in 2013. Mitsubishi Power will supply the core components of the new combined cycle plant from Japan. The gas turbines will be manufactured at the Takasago Machinery Works (Takasago, Hyogo), and the steam turbines at the Hitachi Works (Hitachi, Ibaraki). The generators
will be manufactured by Mitsubishi Electric Corporation.
As well as Talimarjan, Mitsubishi Power has supplied combined cycle power trains, including gas and steam turbines, to a number of other power plants in Uzbekistan: Navoi-1 and Navoi-2; Tashkent TPP; and Turakurgan.
The Singapore contract will see the upgrade, to be completed in 2023, of two of the four 360 MW M701F gas turbines (CCP3 and CCP4) at Tuas Power’s combined cycle power plant in the south west of the country. The upgrade is part of Tuas Power’s efforts to achieve energy efficiency improvements and implement decarbonisation measures “in accordance with the Singapore government’s energy policies.”
Supply of the four gas turbines for Tuas Power goes back to 2001. The upgrade will “introduce the latest gas turbine technologies”, says Mitsubishi Power, which supports the plant under a long- term service agreement. Among measures to be implemented will be improved heat rate by reducing the volume of cooling air.
H-25 gas turbine
The H-25 gas turbine order has been received from Taiwanese firm Chang Chun Petrochemical Co. The 30 MW machine will be the core of a new high-efficiency, natural gas-fired cogeneration facility at the company’s factory in Miaoli City in the north central region of Taiwan. Operation is scheduled to begin around spring 2025, with the CHP plant supplying power

for the company’s factories, and steam for manufacturing processes. This is the second H-25 gas turbine that Mitsubishi Power is supplying to Chang Chun Group, following a machine ordered for a Chang Chun Plastics factory, announced in 2022.
The new gas turbine at Miaoli will replace the existing oil and coal-fired boiler facility, part of a project being implemented in response to local- governmental calls for reduced coal consumption and a shift in Taiwan’s energy policy. Mitsubishi Power has been supplying Chang Chun Group with major equipment for the power and cogeneration facilities at its factories since 1984, including nine steam turbines and five boilers. Mitsubishi Power says it continues to provide after-sales service for the equipment supplied, as well as other types of service offerings. “This latest order is a reflection of the trust established by this track record,” says Mitsubishi Power, “and the long-standing good relations between the two companies.”
GE 6F.03 turbines to power Kazakhstan’s lower-carbon future
GE and Aksa Energy have announced contract signing for the supply of two GE 6F.03 gas turbines to power Aksa Energy’s new 240 MW combined heat and power plant in the Kyzylorda region of Kazakhstan, expected to enter operation in 2025. In addition, GE says it will provide maintenance services to help ensure long-term availability and reliable operation for the equipment.
Kazakhstan is making progress towards improving grid stability, GE notes, and is committed to modernise its power infrastructure as part of the country’s announced long-term objective of reach ing net zero carbon emissions by 2060. Plants comprising the country’s ageing power infrastructure have been operating for an average of 40 years, and there is heavy reliance on coal fired power generation. The new combined heat and power plant in the Kyzylorda region “will help address the growing
demand for reliable and flexible power, while balancing renewable energy and supporting coal phase out”, says GE.
“We believe in the bright future of Kazakhstan, the rising star of Central Asia. Aksa Energy is dedicated to support Kazakhstan’s energy transition through transforming its coal baseload to lower carbon footprint technologies”, said Korkut Ozturkmen, Aksa Energy board member and vice chairman of the executive committee, describing the Kyzlorda CHP plant as a concrete
example of this intention. “We chose GE’s technology based on the evaluation of multiple parameters such as CAPEX, OPEX, performance, delivery cycle, reliability, service as well as flexibility to meet grid operator requirements.” GE says its 6F.03 turbines are “known for their flexibility, turndown, and fuel performance”, drawing “on the best of GE’s scaled H and F-Class technology.” They “offer quick installation and have a large and diversified installed base across approximately 40 countries, with more than 200 units in operation globally”, the company notes.

GE describes the new contract as the latest milestone in its “long-term collaboration in Kazakhstan”, with GE gas turbine technology powering major oil & gas projects, including in the Karachaganak, Kashagan and Tengiz regions, while “GE exhaust gas filtration systems reduce carbon emissions on a number of Kazakhstan energy facilities.“
