ABB has acquired the solar PV and wind inverter and battery storage power conversion system (PCS) businesses of Gamesa Electric.
ABB said the acquired portfolio, which was previously owned by Gamesa Electric’s parent company Siemens Gamesa, includes utility-scale solar PV inverters, PCS for industrial battery energy storage systems (BESS) and wind power converters.
It also includes “key resources” in India, China, the US and Australia, and two converter factories in Madrid and Valencia, Spain. The acquisition began in December 2024.
Gamesa Electric has a history of business in the wind power converter and generator sector, as well as in the solar PV and BESS industries. ABB said the acquisition increases its total serviceable installed base of wind converters by approximately 46GW.

“By combining ABB’s global reach and Gamesa Electric’s portfolio and expertise, the company is well positioned to capture growing demand and accelerate renewable energy adoption worldwide,” said Daniel Gerber, business line manager, renewable power, at ABB’s Motion High Power division.
ABB is looking to capitalise on the predictable demand for electrical equipment components for solar PV projects, BESS and wind power plants; PCS and inverters are essential to the operation of renewable energy assets, even though they represent a small portion of a project’s cost.
One closely related example is Hitachi Energy’s acquisition in early 2025 of Spanish PCS and inverter provider Eks Energy. Formed as Hitachi-ABB Power Grids, Hitachi acquired the Swiss automation company’s grid edge and battery storage solutions, and rebranded as Hitachi Energy, stating that energy storage would be a major focus for its business going forward.
It later acquired Spain’s Eks Energy, a PCS business. Eks Energy CEO Alberto Prieto, appointed by Hitachi Energy to lead the newly acquired subsidiary, told ESN Premium in an interview earlier this year that the majority acquisition “closed a gap” in its portfolio, before the company acquired an outstanding 20% stake in Eks held by the now-bankrupt energy storage system integrator Powin in August.
Energy-Storage.news explored the role that PCS plays in energy storage system management when reporting from the RE+ trade show in 2022.
The solar inverter market is also hugely competitive, with technological and market competition between the largest Chinese suppliers and Western firms like SMA Solar, SolarEdge and Enphase Energy. The European trade group SolarPower Europe has called inverters the “brains” of the solar array, given the increasingly digitised and granular control that the systems can have over PV plants, and has called for EU measures to support domestic inverter producers.
Back in 2020, ABB sold its solar inverter business to Italian inverter firm FIMER “to focus on other growth segments.” The Gamesa Electric acquisition marks a re-entry into the space.
