Siemens Energy is a global energy technology company that designs, manufactures, and services equipment across the entire energy value chain, from power generation and transmission to industrial decarbonization and wind turbines. Spun off from Siemens AG in 2020, the company operates through four main business areas: Gas Services, Grid Technologies, Transformation of Industry, and Siemens Gamesa (its wind energy division). Together, these segments cover fossil fuel power plants, electrical grid infrastructure, industrial process equipment, and renewable energy systems.
Gas Services: Power Generation Equipment
Gas Services is Siemens Energy’s largest and most profitable division. It builds and maintains gas turbines used in power plants around the world, covering everything from new turbine manufacturing to long-term service contracts that keep existing fleets running efficiently. In the first quarter of fiscal year 2026, the division booked 102 gas turbines, its strongest quarter ever for order intake. About 40% of those orders came from the United States, 35% from Europe, and 15% from the Middle East and China. The segment posted a profit margin of 16.6% before special items.
A major focus within Gas Services is preparing gas turbines to run on hydrogen instead of natural gas. Siemens Energy operates a Zero Emission Hydrogen Turbine Center where it tests industrial turbine models (including the SGT-600, SGT-700, SGT-750, and SGT-800) on hydrogen-blended fuel. These turbines can currently burn up to 75% hydrogen in the fuel mix, and the company aims to reach 100% hydrogen capability by 2030. One real-world application: a district heating plant in Leipzig, Germany, uses two SGT-800 turbines that will be successively converted to run entirely on hydrogen.
Grid Technologies: Moving Power Where It’s Needed
Grid Technologies builds the hardware that transmits electricity from power plants and renewable energy sources to the places that use it. This includes transformers, switchgear, substations, and high-voltage direct current (HVDC) transmission systems. It’s the division that helps utilities and governments upgrade aging electrical grids and connect new sources of power.
HVDC technology is a specialty. Siemens Energy’s HVDC PLUS system transmits large amounts of electricity over long distances with less energy loss than conventional alternating current (AC) lines. It comes in several configurations depending on the project: symmetric monopole designs for straightforward point-to-point connections, bipole setups that offer redundancy (if one line fails, the other keeps running), multiterminal systems that link three or more stations into a coordinated network, and back-to-back systems that convert power between different AC frequencies without needing a long DC cable. These systems also help stabilize grids by controlling voltage and power flow, acting as a firewall against cascading blackouts, and even restarting portions of a grid after a total outage.
Demand for grid equipment has surged recently. In Q1 of fiscal 2026, Grid Technologies saw orders jump nearly 22% compared to the same quarter the prior year, driven by data center construction in the United States and broader global investment in transmission capacity to handle growing renewable energy output. The division’s profit margin hit 17.6%.
Transformation of Industry: Industrial Equipment
This segment serves heavy industries like oil and gas, chemicals, mining, and marine transportation. It manufactures compressors, industrial steam turbines, generators, and electrification solutions that keep factories, refineries, and offshore platforms running. In early fiscal 2026, the division reported strong order growth, driven particularly by compressor sales and electrification projects, with several large orders booked in the Middle East.
The practical role here is helping industrial customers shift toward lower-emission operations. That can mean replacing older mechanical drive systems with electric ones, supplying more efficient rotating equipment, or integrating industrial processes with cleaner power sources.
Siemens Gamesa: Wind Turbines
Siemens Gamesa is Siemens Energy’s wind power division, covering both onshore and offshore wind turbines. It designs, manufactures, installs, and services turbines for wind farms globally. The unit has been the company’s biggest financial challenge. Siemens Gamesa posted a loss of 1.36 billion euros in 2025, stemming from quality issues, project delays, and cost overruns that predated its full absorption into Siemens Energy.
The trajectory is improving. In Q1 of fiscal 2026, operating losses narrowed significantly to negative 46 million euros, suggesting the restructuring is gaining traction. Management has targeted breakeven for the full fiscal year. Orders for the quarter came in at 1.5 billion euros, down from a prior-year period that included an unusually large 1.4 billion euro offshore order in the North Sea.
The wind division’s future structure is an open question. Activist investor Ananym Capital has pushed for an eventual spin-off, arguing Siemens Gamesa could be worth around $10 billion as a standalone company. Other major shareholders, including Union Investment, see the wind unit as central to Siemens Energy’s overall turnaround and oppose splitting it off prematurely. Siemens Energy’s leadership has acknowledged the spin-off idea has merit but wants to restore profitability first.
Green Hydrogen Production
Beyond adapting gas turbines to burn hydrogen, Siemens Energy also manufactures the equipment that produces green hydrogen in the first place. The company builds electrolyzers, machines that use electricity (ideally from renewable sources) to split water into hydrogen and oxygen. Siemens Energy opened a dedicated electrolyzer factory with a target production capacity of at least three gigawatts per year. For context, three gigawatts of electrolyzer capacity could produce enough hydrogen to displace significant volumes of natural gas in industrial heating, chemical production, or power generation.
This positions the company on both sides of the hydrogen equation: making the equipment that produces hydrogen and making the turbines that burn it for electricity or heat.
How the Business Fits Together
Siemens Energy’s strategy is built around the idea that the energy transition won’t happen overnight. Gas turbines remain essential for reliable electricity while renewable capacity scales up. Grid infrastructure needs massive upgrades to handle decentralized power sources like wind and solar. Industrial customers need cleaner equipment without sacrificing productivity. And hydrogen ties multiple segments together as both a product and a fuel source.
The company generates revenue from two main streams: selling new equipment and providing ongoing service contracts. Service agreements on installed gas turbines and grid equipment create recurring revenue that tends to be more stable and higher-margin than new equipment sales. With a global installed base spanning decades of Siemens-built power infrastructure, that service portfolio is substantial.
