Hitachi Energy, a global leader in electrification, has completed the acquisition of the remaining stake in EKS Energy, a technology and market leader in power electronics and control solutions, to deliver a scalable, flexible, and complete approach for energy storage customers. Hitachi Energy acquired a majority stake in EKS Energy in 2023.
As energy storage emerges as a cornerstone of grid stability, reliability, and energy security, the IEA¹ has called for a sixfold increase in global storage capacity to 1,500 GW by 2030. Underscoring this urgency, the COP29 Global Pledge2 highlights energy storage and grid infrastructure as essential to building resilient, decarbonized energy systems worldwide.
The integration of EKS Energy’s innovative technology, talent, and enterprising spirit provides Hitachi Energy with greater strategic and operational flexibility. It allows the company to streamline solution integration, further expand its power conversion and energy storage business, and respond rapidly to evolving customer needs.
“As the worldwide market leader in grid automation solutions, the acquisition of eks Energy strengthens our leadership position, enabling one of the industry’s most comprehensive solution portfolios that combines proven converter and control technology with Hitachi Energy’s global scale, unparalleled grid expertise, and digital capabilities,” said Massimo Danieli, Managing Director of Hitachi Energy’s Business Unit Grid Automation. “The acquisition furthers our global strategy, ensuring continuity for existing customers while unlocking new opportunities for innovation and growth.”
Since 2023, the team has strengthened capabilities for power conversion solutions, including the development of a center of excellence in Seville, Spain, where the business is headquartered, to foster deeper collaboration across R&D, product development, and customer delivery.
Additionally, Hitachi Energy’s power conversion solutions business has demonstrated strong commercial momentum and technical leadership across the globe, playing a key role in major energy storage projects such as the Waratah Super Battery in New South Wales, which recently reached key milestones including commercial operation (COD) and full registration under the System Integrity Protection Scheme (SIPS), a fast-acting grid support system designed to maintain stability during critical events. The business has also expanded its global footprint, positioning Hitachi Energy to better serve energy storage customers across key global markets. The successful development and launch earlier this year of a new liquid-cooled WD4 converter platform further enhances performance and scalability across BESS applications for system integrators.
Power converters play a critical role connecting power sources with power supplies, making sure that currents and voltage are balanced correctly for end-user demand. They are data-intensive systems, and when paired with Hitachi Energy’s internet of things (IoT) connectivity and energy management capabilities, they deliver rich insights and analytics to maximize reliable energy supply. The completion of the acquisition will enable Hitachi Energy to innovate faster and improve the technology at this critical grid connection point.
Hitachi Energy is making unparalleled investments in its global footprint and people, continuously pioneering technologies to enable the world’s energy system to be more sustainable and secure and resilient, and acquisitions are playing a critical role in supporting the company’s broader strategy.
