The Gas Turbine Crisis May Be Ending

Is the “turbine crisis” coming to an end? Or at least the end of the beginning?

One of the few bright spots for renewables this year has been that their main competitor for energy generation, natural gas, has been in a manufacturing crunch. An inability (or unwillingness) to ramp up production of turbines, the core component of a gas-fired power plant, to meet rising energy demand is cited regularly by industry executives and financiers to explain why renewables are the best solution to quickly getting power. And it’s reflected in the data; planned additions to the grid are overwhelmingly solar and storage.

But now there might be more turbines coming. Mitsubishi Heavy Industry chief executive Eisaku Ito told Bloomberg over the weekend that it aims to double its capacity to build gas turbines over the next two years.

The industry is essentially an oligopoly of three suppliers: Mitsubishi, GE Vernova, and Siemens Energy. Due to the high level of capital investment necessary to build turbines, there’s little chance of the triumvirate expanding. This means it’s a seller’s market. Developers describe having to be vetted by their suppliers for a product that might get delivered in five years, instead of suppliers fiercely competing for new business. That means for the turbine crisis to be truly reversed, executives (and investors) at Mitsubishi’s two competitors will have to be convinced that large-scale capacity expansions are worth it.

Something that might help them reach that conclusion is if capacity expansion plans are met with a higher stock price. In another ominous development for the renewable energy industry, Mitsubishi’s stock price went up in response to the news. Renewable developers have enough problems on their hands without having to worry about a gas turbine industry that could supply more and more megawatts over the medium term.

Gas turbine manufacturers have been trying to navigate the tension of fulfilling orders for new gas turbines and avoiding costly investments in new capacity that might not actually be utilized should the AI boom peter out, let alone if public policy makes it much more difficult to build new fossil-powered generation.

Up until now, manufacturers — and their investors — have seemed content with heavy demand and constrained supply. Going into the weekend, the stock prices of the gas turbine industry powerhouses GE Vernova, Siemens, and Mitsubishi Heavy Industry had risen 86%, 79%, and 69% so far this year.

But Mitsubishi Heavy Industry’s stock bump on Tuesday indicates that investors are not completely averse to capacity expansion. Yet at the same time, executives across the industry are careful to portray themselves as thoughtful and prudent stewards of capital.

Ito emphasized that the planned capacity expansion would not mean reckless investments, telling Bloomberg “the goal is to be as lean as possible” and that there would be work on the efficiency of the production process to address spiraling costs of turbine manufacturing.

“The executives seem keen to stress that this expansion will be lean and efficient,” Advait Arun, a climate and infrastructure analyst at the Center for Public Enterprise and the author of a much-cited Heatmap article on the turbine shortage, told me. “There’s a tension between getting over their skis by expanding overmuch while also killing the goose that’s laying their golden egg by not expanding.”

The pressure to build is immense — but so is the industry’s hard-won reticence about expansion.

Gas turbine orders are likely to hit a new record this year, according to S&P Global Commodities Insights, and the industry might be unwilling to go further.

“Past boom-and-bust cycles have made the industry cautious in its investments, and turbine demand in the early 2030s is uncertain,” S&P analysts wrote.

Siemens Energy chief executive Christian Bruch had told Morgan Stanley analysts in a note released Tuesday that the company had “no intention” of increasing capacity beyond working to expand the facilities it already has. He also said the company’s constraints are its own supply chain issues, namely the blades and vanes used in the turbines

And GE Vernova has been practically bragging about how far back they have reservations for turbines. “Our pipeline of activity for gas demand is only growing, but it is growing at even more healthy levels for 2029 deliveries, 2030, 2031,” the company’s chief executive Scott Strazik said on an earnings call in July.

And Wall Street has been happy to see developers get in line for whatever turbines can be made from the industry’s existing facilities. But what happens when the pressure to build doesn’t come from customers but from competitors?
