Hitachi Energy and TransnetBW Partner to Bolster Grid Resilience with Supercapacitors

by Anna

Hitachi Energy, a global leader in sustainable energy solutions, has announced a strategic collaboration with TransnetBW, a prominent German transmission system operator, aimed at fortifying grid stability and advancing renewable energy integration. The partnership underscores the critical need for resilient infrastructure as the world transitions towards a renewable energy future.


Challenges of Grid Stability in the Renewable Energy Era

As the world increasingly embraces renewable energy sources like solar and wind, ensuring grid stability becomes paramount. The intermittent nature of renewables poses challenges in maintaining consistent voltage and frequency levels across the electrical network, potentially leading to disruptions and equipment damage. Traditional grid stability methods are inadequate to address the variability introduced by renewables, necessitating innovative solutions and investments in resilient infrastructure.


Deploying Supercapacitors for Enhanced Grid Stability

Hitachi Energy’s partnership with TransnetBW involves the deployment of supercapacitors, a cutting-edge energy storage technology, to bolster grid stability. Supercapacitors offer rapid charging and discharging rates, enabling efficient storage and release of surplus power during peak demand periods. This enhances grid stability by smoothing fluctuations in voltage and supporting active and reactive power compensation.

Hitachi Energy’s Advanced Solutions for Grid Stabilization

The collaboration will see the deployment of Hitachi Energy’s advanced static synchronous compensator (STATCOM) stations equipped with supercapacitors and the company’s proprietary grid stabilization technology, SVC Light Enhanced. These stations will enhance power quality and stability across TransnetBW’s transmission grid, benefiting millions of individuals and industries.

Benefits of Hitachi Energy’s Integrated System

Hitachi Energy’s integrated system combines essential power quality and grid stabilization technologies in a compact unit. By leveraging supercapacitors and advanced control features like Grid Forming Control, the solution offers significant reductions in carbon footprint and adapts to evolving network changes. It enables increased transmission capacity without the need for additional infrastructure, ensuring grid stability amidst the growing penetration of renewable energy.

Towards a Sustainable Energy Future

The deployment of supercapacitors and advanced grid stabilization technologies represents a pivotal step towards achieving a sustainable energy future. These solutions not only enhance grid resilience but also facilitate the seamless integration of renewable energy sources, driving towards a more efficient and environmentally friendly energy transition.


As the world grapples with the challenges of renewable energy integration and grid stability, collaborations like the one between Hitachi Energy and TransnetBW offer promising solutions. By harnessing innovative technologies and fostering partnerships, the energy industry can overcome obstacles and pave the way for a resilient and sustainable future.
