ABB has finalized the acquisition of Gamesa Electric’s power electronics division, expanding its global footprint in wind, solar, and battery storage conversion technologies. The deal strengthens ABB’s position in renewable power systems and scales its installed wind converter base across multiple continents.
ABB acquisition expands its power electronics capabilities
On December 2, 2025, ABB announced the completion of its acquisition of the power electronics business of Gamesa Electric in Spain from Siemens Gamesa, originally disclosed on December 18, 2024. Financial terms were not released. The acquired unit reported annual revenue of about EUR 145 million for the fiscal year ending September 30, 2025.
The newly integrated portfolio includes power conversion technologies such as wind converters for doubly fed induction generators, industrial battery energy storage systems, and utility scale solar inverters.
The transaction covers roughly 400 employees, including key teams in India, China, the United States, and Australia, as well as two converter manufacturing facilities in Madrid and Valencia. ABB also entered into a supply and service agreement with Siemens Gamesa. The acquisition increases ABB’s total installed base of wind converters by approximately 46 gigawatts and supports the profitable growth strategy of its Motion business area. With more than 45 years of experience in power electronics, Gamesa Electric brings deep technical expertise in solar and renewable applications and longstanding customer relationships.
“By combining ABB’s global reach with the portfolio and expertise of Gamesa Electric, the company is well positioned to meet rising demand and accelerate renewable energy adoption worldwide,” said Daniel Gerber, Business Line Manager for Renewable Power within ABB’s Motion High Power division.
According to the International Energy Agency, global renewable electricity generation is expected to grow by 60%, rising from 9,900 TWh in 2024 to 16,200 TWh in 2030. Renewables are projected to surpass coal by the end of 2025, or by mid 2026 at the latest depending on hydropower availability, becoming the world’s largest source of electricity generation. Solar photovoltaic alone accounts for more than half of this growth, followed by wind at roughly 30%.
