What They Do

Siemens Energy focuses on energy technology across the entire value chain, including power generation, transmission, and storage. Core areas include gas turbines, steam turbines, hybrid power plants with hydrogen, power generators, transformers, and renewable technologies led by Siemens Gamesa Renewable Energy (SGRE). This positioning makes the company a global leader in wind energy, with technologies estimated to support about one-sixth of the world's electricity generation (source: siemens-energy.com). The products and services include both conventional and renewable energy solutions, such as onshore and offshore wind turbines from SGRE, grid infrastructure, and hydrogen electrolysis systems that help customers reduce carbon emissions and enhance efficiency through integrated systems for resilient energy grids (source: energydigital.com).

Projects & Track Record

Notable completed projects include the first power plant in South Africa, built in 1895 by Siemens' predecessors, as well as the introduction of high-voltage direct current systems in 1903. Modern achievements include the manufacturing of critical components for regional energy centers and supporting one-sixth of global electricity through its technologies (source: energydigital.com). Current major projects include a 280-megawatt electrolysis system being delivered to the utility EWE in Germany, expected to produce up to 23,000 tons of green hydrogen annually. Additionally, there are localization efforts such as the Siemens Energy Dammam Hub in Saudi Arabia for component manufacturing to strengthen resilient energy sectors (source: energydigital.com).

Recent Developments

In the past two years, Siemens Energy reported strong results for fiscal year 2023 with a revenue of 31 billion euros, despite challenges in the wind business.
