is worth nothing. These units have to run when they are required to run. They must be available,” not least, within the European context, to fulfil obligations and earn money under a capacity remuneration regime.
“We start with a little bit of a disadvantage because we haven’t been present in the European H class market. But a message being emphasised is our higher reliability over the long term, reflected, for example, in lower insurance costs.

its gas turbine market share is low, about 3-4%. The company has sold some F class machines in Poland and H100 units in Germany for CHP, but nothing at the H class end of the market, where the JAC technology is pitched.
One reason is that “for the big units we didn’t have any sales organisation”, says Jose. “Now we are bidding more actively than two years ago. The number of bids we are doing today is three times what we were doing. And because we have an organisation dedicated to it, results will come.” The aim is to increase market share to about 15-20%, “although it will not happen overnight, of course, and we have to be a bit patient”, cautions Jose. The bidding strategy will also focus
on projects where there are significant benefits for reliability, fast start up and a high level of operational flexibility –playing to the strengths of the JAC technology.
One reason he is confident that his product “has the potential for success in Europe” is that it is “ready for the future”, with Mitsubishi making big investments in hydrogen combustion and carbon capture technology development. Also, “our technology is ahead of the curve in terms of reliability”, he says. “There is a race in the big-turbine business, everybody is investing to get the biggest output and highest efficiency, but I think we’re missing the point that the most efficient gas turbine that doesn’t have reliability
“For validation we deploy new gas turbines in a power plant (T-Point at Takasago) that sells electricity into the Japanese market. So, before we offer JAC technology commercially it has clocked up about 10 000 hours of operation in a real power plant setting, allowing us to gauge reliability over an extended period before we bid any projects. That’s our approach to business.” A further important selling point is that the new EMEA combined cycle business unit will be supported by Mitsubishi Power’s highly experienced network of “dynamic service centres across the region.”

Recent Mitsubishi Power CCGT successes outside Europe
Looking at the global gas turbine market as a whole, not just Europe, Mitsubishi Power says it “captured the top market share by megawatts in the first quarter of 2021 with a global gas turbine market share of 29.0%”, according to it McCoy Power Reports data. The company also notes that it secured 40.8% of the heavy-duty gas turbine market (100 MW unit size and above), “led by Mitsubishi Power’s latest model JAC gas turbines.” Mitsubishi Power has extensive experience with heavy-duty machines, including the F, G and J series. The G series has surpassed 5.6 million actual operating hours (AOH) with 94 units now in commercial operation, while the J series has surpassed 1.3 million AOH with 46 units now in commercial operation. A key contributor to Mitsubishi Power’s leading market share in Q1 21 was the order for two M701JAC gas turbines for a 1500 MW combined cycle power plant under construction in Sirdarya, Uzbekistan, the first large-scale IPP project in that country, where Mitsubishi Power has a strong presence. Another recent JAC development reported by Mitsubishi
Power was the shipping from its Savannah Machinery Works, GA, USA, of an M501JAC gas turbine to Marlim Azul Energia’s power plant in Macaé, Rio de Janeiro. Due to enter operation in January 2023, it will be the first plant to run on associated gas from Brazil’s pre-salt basin. Eight JAC turbines, the M701JAC 50 Hz version, also feature in two combined cycle plants currently construction in Thailand, in
Chonburi and Rayong provinces, with a total installed capacity of 5300 MWe. The first of the eight, southeast Asia’s lead M701JAC unit, was recently inaugurated at the Chonburi site. In China, Mitsubishi Power has recently won an order to supply a 180 MW blast-furnace-gas fuelled combined cycle plant to steelmaker Jiangsu Shagang Group, employing an M701SDAX gas turbine. This builds on the company’s greater than 60% global market share in BFG-fired gas turbines. In Egypt, Mitsubishi Power has recently concluded, simultaneously, three long-term service agreements, 16 year duration, covering six M701F gas turbines, two each at the Sidi Krir, El Atf and Cairo North combined cycle power stations. Meanwhile, in Japan, Mitsubishi Power led the consortium
that has recently completed the construction and subsequent handover of the 540 MWe coal fuelled Nakoso air-blown IGCC (integrated gasification combined cycle) power plant in Iwaki, Fukushima. Mitsubishi Power’s scope included the gasification system as well as the gas and steam turbines. It is the world’s largest IGCC plant, roughly twice the installed capacity of the Nakoso unit 10 air-blown IGCC demonstration plant completed previously, and also the first commercial application Japan’s indigenously developed air-blown IGCC technology. Compared to unit 10, power generation efficiency has been substantially enhanced, reaching some 48% (LHV) – largely achieved by increasing the gas turbine firing temperature.
