Swiss industrial giant ABB has announced the completion of the acquisition of Gamesa Electric’s power electronics business in Spain, which was previously part of Siemens Gamesa. The deal was first announced in December 2024 and culminated on December 2, 2025
The acquisition includes various power conversion products like wind converters designed for doubly-fed induction generators (DFIG), industrial battery energy storage systems (BESS), and utility-scale solar inverters.
The deal brings about 400 new employees to ABB, including important team members from India, China, the United States, and Australia, along with two converter factories located in Madrid and Valencia. ABB has also formed a supply and services agreement with Siemens Gamesa.
This acquisition will increase ABB’s serviceable installed base of wind converters by approximately 46 gigawatts and supports the company’s growth strategy in the Motion business area.
Gamesa Electric has over 45 years of experience in power electronics and possesses extensive technical knowledge in solar and renewable applications, along with strong relationships with customers.
“By combining ABB’s global presence with Gamesa Electric’s products and expertise, we are well-positioned to meet growing demand and promote the use of renewable energy worldwide,” said Daniel Gerber, Business Line Manager for Renewable Power in ABB’s Motion High Power division.
Solar photovoltaic (PV) energy is expected to account for more than half of this increase, followed by wind energy, which is projected to contribute about 30 per cent.
By integrating Gamesa Electric’s technology, manufacturing capacity, and global workforce, ABB strengthens its ability to offer end-to-end solutions for wind, solar, and energy-storage applications. Given the rapid growth in demand for solar and battery-storage solutions globally, this move appears to position ABB to capitalize on rising interest in clean-energy infrastructure, utility-scale renewables, and grid modernization.
