On Aug. 29 Mitsubishi Heavy Industries said it will double global gas-turbine production capacity over the next two years, abandoning an earlier plan for a 30% uplift. The expansion targets utilities, industrial customers and the fast-growing data centre sector, which executives and analysts have identified as a major new source of incremental demand, according to comments attributed to chief executive Eisaku Ito. The company has also raised profit guidance for the fiscal year, leaving the two-year build-out and the updated earnings outlook as the immediate milestones for investors and customers.

Mitsubishi Heavy Industries, known as MHI, told investors the jump to roughly 100% capacity growth reflects accelerating order flows that have outstripped an earlier plan to increase output by 30%. Company chief executive Eisaku Ito made the announcement on Aug. 29 and said meeting outstanding orders is a top priority. He said MHI will push manufacturing efficiency and tighten supply-chain protocols to lift output.

Why data centres and ageing plants are driving demand

The demand case presented by MHI and industry commentary centres on two structural trends. First, hyperscale data centres are emerging as a major incremental source of turbine orders. Executives and analysts cited the computing sector alongside utilities and industrial users as key buyers. Second, a wave of decades-old gas turbines reaching the end of their useful life is prompting widespread replacement of plant equipment, supporting sustained demand for new natural-gas-fired capacity and flexible generation.

Other manufacturers are reporting parallel trends. One financial analysis group told reporters that new orders for a rival reached about 55 gigawatts and could hit 60 gigawatts by year-end. Siemens Energy has reported double-digit year-on-year growth in orders, with a substantial share tied to data centres, which industry commentary linked to the same demand drivers MHI cited. GE Vernova was also named as another competitor seeing rising order inflows.

Costs, bottlenecks and market reaction

Company sources have warned that manufacturing costs have risen sharply in recent years because of higher raw material, component and labour prices. One account said costs have nearly doubled, and MHI has signalled it will seek efficiency gains to offset those pressures. Sources also noted practical constraints in the sector, including long delivery waits due to backlogs and limits on skilled labour and complex engineering resources. Even as manufacturers add capacity, those bottlenecks are expected to persist.

Mastheads

MHI is taking several supply-side actions. One source recorded specific measures such as forming partnerships and using overseas production sites to scale output.

That same report said MHI had placed an order with a Chinese turbine maker for 150 units as part of its approach, though that detail appears only in the single report and should be treated cautiously until further confirmation.

The rush to add capacity has been reflected in MHI’s recent financials. The company reported strong quarterly results and raised profit guidance for the fiscal year to 240 billion yen, an upward revision of more than 8% versus prior guidance, with record third-quarter earnings driven largely by turbine demand, according to the company. One report gave more granular quarterly figures, saying consolidated order intake was 1,768.6 billion yen and revenue was 1,193.6 billion yen for the quarter ending June 30, 2025, with business profit up 24.7% year-on-year and a companywide order backlog cited at 5.3 trillion yen. Those specific figures come from a single account and haven't been universally reported across the coverage.

Markets reacted to the expansion headlines. One report recorded shares rising intraday by as much as 2.5% after the announcement, with a later note showing the stock trading at 2,218 yen per share. That positive response reflected investor confidence that stronger turbine demand can sustain margins and justify capital spending to lift output.

Not all sourcing aligns perfectly. Two accounts differed on the timing of Ito’s appointment as CEO, with one saying he was appointed in December and assumed the role earlier in the year, while another put his start in April.

Both pieces attributed the comments to company reporting but didn't reconcile the discrepancy. The presence of single-source technical and financial details in some reports highlights the value of triangulation as MHI scales production and reports further results.

Ito announced the plan on Aug. 29. The coming two years will test MHI's ability to scale manufacturing, ease supply constraints and convert its backlog into timely deliveries.
