Hitachi Energy completed the acquisition of the remaining stake in eks Energy, a provider of power electronics and control solutions for energy storage. The company had acquired a majority stake in eks Energy in 2023. This transaction helps to reinforce Hitachi Energy’s global position and offerings in advancing energy storage innovation.
As energy storage continues to emerge as a critical pillar of grid stability and security, the International Energy Agency has called for a sixfold increase in global storage capacity to 1,500 gigawatts by 2030. The COP29 Global Pledge also highlights energy storage and grid infrastructure as essential to building resilient and decarbonized energy systems globally.
The integration of eks Energy’s technology and personnel help to provide Hitachi Energy with greater strategic and operational flexibility to expand its power conversion and storage business. Since 2023, the collaboration has included the creation of a center of excellence in Seville, Spain, supporting research, product development, and delivery. Recent milestones include:
Expanded global footprint to serve energy storage customers across key markets
Contribution to the Waratah Super Battery in New South Wales, achieving commercial operation and full registration under the System Integrity Protection Scheme
Development and launch of the liquid-cooled WD4 converter platform to help enhance performance and scalability across battery energy storage applications
Power converters play a central role in balancing currents and voltage between power sources and supply. When combined with Hitachi Energy’s digital connectivity and energy management solutions, they provide additional insights and analytics that help to improve system reliability. The completion of the eks Energy acquisition helps to enable faster innovation at this critical grid connection point.
This acquisition reflects a broader industry trend of strengthening grid-edge technologies to help support more secure and sustainable energy systems. By combining advanced power electronics, digital capabilities, and a global service presence, companies are positioning themselves to better meet the rising electricity demand while accelerating the energy transition.
