As power systems around the world become increasingly reliant on renewable energy, the focus is shifting from adding clean generation capacity to ensuring that electricity networks can integrate it reliably and efficiently. In this context, battery energy storage is emerging as one of the key enablers of the energy transition.
In a new CESI View, Luca Migliorini, Energy Transition Project Center Director at CESI Consulting, examines how Battery Energy Storage Systems (BESS) are evolving from a supporting technology into a strategic infrastructure asset for modern power systems. Drawing on CESI’s expertise in grid studies, system planning, battery testing and power system analysis, the article explores the growing interdependence between storage and electricity networks.
The View highlights how battery storage can support grid stability, resource adequacy, renewable integration and network resilience, while also providing essential flexibility in systems characterized by increasing shares of wind and solar generation. It further examines the importance of rigorous grid integration studies, independent testing and data-driven asset management throughout the lifecycle of storage projects.
As electrification accelerates and new demand drivers such as data centers reshape load profiles, battery storage is becoming a cornerstone of a more flexible, resilient and reliable energy system. Through this expert perspective, Luca Migliorini offers valuable insights into one of the most significant infrastructure challenges and opportunities shaping the future of the global energy transition.
