Siemens Energy’s Record Backlog Creates a Four-Year Wait — and a Test for German Infrastructure

Siemens Energy's record €154B order backlog causes four-year turbine delivery delays. CEO urges German policy action as US AI demand surges; stock down 21% from peak.

Customers placing an order for a gas turbine at Siemens Energy today will wait up to four years for delivery. That wait time, unprecedented in the company’s history, is the clearest sign yet of just how stretched the world’s appetite for power-generation equipment has become. The group now carries firm orders for turbines totalling 60 gigawatts of capacity, with another 27 GW already reserved. The accompanying service contracts alone are expected to generate roughly €35 billion over the next two decades.

The result is a €154 billion order backlog — a figure that has become both a trophy and a headache. On one hand, it locks in years of production. On the other, it raises a nagging question for investors: how much of that mountain will translate into revenue and profit in the near term? The answer increasingly depends on factors beyond Siemens Energy’s control.

CEO Christian Bruch has started to direct that question squarely at policymakers in Berlin. Germany plans to auction 10 GW of new gas-fired capacity this year, with an eye to later converting those plants to hydrogen. But local opposition is already killing projects before they break ground. The shelved Edgeconnex development in Maintal, where a planned gas plant to back up a data centre ran into community resistance, serves as a warning. For every such failure, a piece of the order book stays on paper longer.

Bruch’s frustration is sharpened by what he sees across the Atlantic. Siemens Energy’s grid-technology division is riding a wave of demand from US data centre operators scrambling to power the artificial-intelligence boom. The unit is forecast to post revenue growth of up to 27% in the current fiscal year. Meanwhile, Germany’s total data centre capacity stands at about 3 GW, with only 500 MW dedicated to AI workloads — a figure the government wants to double to 6 GW. In the US and China, the scale of ambition is already an order of magnitude larger.

The company’s own financial outlook reflects the imbalance. Management expects revenue to climb as much as 16% in the 2026 financial year, with pre-tax free cash flow reaching around €8 billion. But those projections assume the infrastructure bottlenecks at home do not tighten further.

At the stock market, the tension between the megatrend narrative and the operational reality is playing out in the price. Siemens Energy shares ended the week at €153.46, up 1.39% on the day but nursing a monthly loss of roughly 14%. Over twelve months the stock still shows a gain of nearly 79%, though the euphoria of late April, when it hit a 52-week high of €195.54, has evaporated. From that peak the shares have dropped 21%.

Technical indicators paint a mixed picture. The relative strength index stands at 42.7, neutral territory with no clear signal. The stock trades about 9% below its 50-day moving average — the next resistance sits near €168 — while remaining more than 12% above the 200-day line. The underlying trend is intact, but the near-term momentum has stalled. Annualised volatility of 54% leaves little room for complacency.

For Siemens Energy, the path forward is less about its own execution than about Germany’s willingness to build. The autumn quarterly figures will offer one measure of how fast the backlog is converting into cash. Whether that conversion accelerates or stalls will depend on whether the country’s political system can clear the way for the very infrastructure the energy transition and the AI boom both demand.
