JAC turbines to power UAE’s largest power plant
Mitsubishi Power has shipped three M701JAC gas turbines to the Fujairah F3 power plant in the UAE from its Takasago Machinery Works in Hyogo Prefecture. At 2400 MW, it will be the largest natural gas fuelled combined cycle facility in the UAE.
The plant will be owned and operated by Fujairah Power Company F3 LLC, a special purpose company jointly owned by Abu Dhabi National Energy Company (TAQA) and Mubadala Investment Company, as well as Marubeni Corporation and Hokuriku Electric Power Company.
Senoko upgraded
Mitsubishi Power has completed upgrade works on two combined cycle power plants equipped with M701F gas turbines at Senoko Energy, Singapore – resulting in increased efficiency equivalent to a 15 000 t/y reduction in carbon dioxide emissions annually. The upgrade, carried out under a long- term service agreement (LTSA), included the application of Mitsubishi’s latest gas turbine technologies to the M701F gas turbines at Senoko, achieving a heat rate improvement by reducing the volume of cooling air. Work on the upgrade and LTSA began in June 2019, as part of Senoko Energy’s efforts to improve energy efficiency and decarbonise in line with Singapore’s Carbon Pricing Act, which introduced subsidies for company efforts resulting in reductions in carbon dioxide emissions (

The plant is being built by Samsung C&T Corporation in a coastal area of Fujairah (Qidfa), approximately 300 km north east of of Abu Dhabi.
Full commercial operation is scheduled to commence in 2023.
Under a long-term service agreement (LTSA) for the project, Mitsubishi Power will handle maintenance and repair of the power plant. The M701JAC is capable of achieving efficiency greater than 64% in combined cycle and reliability of 99.6%, says Mitsubishi Power. It is also capable of operating on a mixture of

up to 30% hydrogen and 70% natural gas, with the possibility of operating on 100% hydrogen in the future.
Using TOMONI to improve performance at Joetsu 1
Joetsu 1 combined cycle plant, Japan
Mitsubishi Power has concluded a contract with Tohoku Electric Power to deploy TOMONI digital O&M support technology at the Joetsu unit 1 combined cycle plant, Joetsu city, Niigata Prefecture, which is scheduled to start operations in December 2022.
The implementation of TOMONI at the 572 MW class JAC gas turbine will provide a real-time operation monitoring system employing “cutting- edge data analysis”, says Mitsubishi Power. It will result in increased efficiency, reduced emissions, and more effective operations & maitenance, the company says.
Construction of Joetsu unit 1 began in 2019 and trial runs were scheduled to start in March 2022.

TOMONI “intelligent digital solutions”, as to be applied at Joetsu 1, allow the various services provided by TOMONI to be made available via cloud computing accessible from the power plant owner/operator’s computer. Joetsu unit 1 will be able to utilise TOMONI data analysis applications

to support O&M, and optimise plant efficiency and equipment inspections, helping to reduce plant maintenance and operation costs. The long-term effectiveness of TOMONI has, says Mitsubishi Power, been confirmed at its T-Point 2 facility (Takasago works), which is a grid-connected power plant operated remotely employing the TOMONI HUB.
Looking forward, TOMONI, “through highly sophisticated data analysis and cooperation with customers, is paving the way towards the future realisation of smart, autonomous power plants”, says Mitsubishi, which “will seamlessly integrate power grids, energy storage systems, and renewable energy.”
Mitsubishi Power has recently announced that it is establishing its first TOMONI HUB in Europe at its Duisburg office in Germany, the company’s centre of excellence within
EMEA.This will bring the number of TOMONI hubs operating worldwide to five, the others being in Japan (two), the USA and the Philippines.
