Energy technology
What does Siemens Energy — and future Omterra — actually do?
Siemens Energy is a global energy technology company serving the entire energy system, from power generation to transmission and renewable energy. Its portfolio includes gas and steam turbines, generators, transformers and grid technologies, while Siemens Gamesa adds a major global wind power business covering both onshore and offshore wind turbines and related services.
Under the Omterra name, these established capabilities are being brought together under one brand. That means Omterra will be associated with technologies used to generate electricity, move power through modern grids and expand renewable energy capacity around the world.
Power generation
Siemens Energy develops gas turbines, steam turbines, generators and power plant technologies used in utility-scale and industrial electricity generation, including solutions designed to support more efficient and lower-carbon energy systems.
Grid technologies
The company supplies transformers and technologies for power transmission and electrical grids, helping move electricity reliably from where it is generated to homes, businesses and industry.
Onshore and offshore wind
Through Siemens Gamesa, the group develops, manufactures and services onshore and offshore wind turbines, making wind power and renewable energy a central part of the future Omterra portfolio.
History
From Siemens and Siemens Gamesa to Omterra
1988–2000
ABB and ABB Alstom Power
ABB was created in 1988 from the merger of ASEA and Brown Boveri. In 1999 ABB and Alstom combined their power-generation activities in ABB Alstom Power; Alstom acquired ABB’s remaining share the following year. Part of this industrial turbine heritage would later move to Siemens.
1998
Westinghouse Power Generation joins Siemens
Siemens acquired Westinghouse’s fossil-fuel power generation business, significantly strengthening its global gas turbine, steam turbine, generator and power-plant portfolio.
2003
Alstom industrial turbines acquired
Siemens acquired Alstom’s small and medium gas turbine and industrial steam turbine businesses. Those operations included technology and manufacturing lines that had previously passed through ABB Alstom Power and Alstom Power.
2004
Siemens enters wind through Bonus Energy
Siemens acquired Danish wind turbine manufacturer Bonus Energy, establishing the business that became Siemens Wind Power and adding a major renewable-energy branch to the group.
2017
Siemens Gamesa takes shape
Siemens Wind Power and Gamesa combined to create Siemens Gamesa Renewable Energy, bringing together large onshore and offshore wind portfolios and service operations.
2020
Siemens Energy becomes independent
Siemens separated its energy activities into the standalone Siemens Energy group, bringing together power generation, transmission technologies and its majority stake in Siemens Gamesa.
2023
Siemens Gamesa fully integrated
Following the acquisition of the remaining shares and the delisting process, Siemens Energy became the sole shareholder of Siemens Gamesa, paving the way for closer integration of the wind business.
2026+
Transition to Omterra
Siemens Energy and Siemens Gamesa are being brought together under the Omterra name and brand umbrella, with the transition introduced in stages.
For customers
Same capabilities. New name.
The practical challenge of a rebrand is trust. Customers who know Siemens Energy — including customers familiar with Siemens Gamesa in onshore and offshore wind — may not immediately recognise Omterra. Clear transition messaging should connect the established names with the new brand without creating confusion about ownership or affiliation.
This site is designed as a bridge: whether you search for Siemens Energy or Siemens Gamesa, understand the new Omterra name, then continue to official company channels.

Common questions
Is Siemens Energy becoming Omterra?
Yes. Siemens Energy has announced that Siemens Energy and Siemens Gamesa Renewable Energy will be united under the Omterra name and brand umbrella. Exact legal-entity and country-specific timing should be checked against official sources.
What happens to Siemens Gamesa?
Siemens Gamesa, the wind power business known for onshore and offshore wind technology and services, is also part of the announced Omterra brand transition. Siemens Energy and Siemens Gamesa are intended to share the single Omterra brand umbrella.
Is Omterra a completely different company?
The rebrand is intended to create a new identity for the existing energy business rather than describe an unrelated startup.
Why can I still find Siemens Energy online?
Large global rebrands take time. Search results, legal entities, documents, websites and customer references may continue to contain the former name during and after the transition.
Is this an official Siemens Energy or Omterra website?
No. This is an independent informational project and is not affiliated with or endorsed by Siemens AG, Siemens Energy, Siemens Gamesa or Omterra.
