EU Regulation: Grid-Forming Requirements for Energy Storage

Starting in 2028, the European Union will require energy storage systems exceeding 1 MW to possess grid-forming capabilities. The mandate, detailed in a recent technical report by ENTSO-E, aims to bolster grid stability. New and significantly renovated energy storage facilities must actively regulate voltage and frequency, mimicking synchronous generators. The report specifies technical requirements for these systems. Crucially, systems must maintain voltage stability during fluctuations. They also need a rapid response time of under 10 milliseconds. Synthetic inertia support is another key requirement. Compliance testing will ensure stable operation during grid disturbances. Energy storage project developers face a deadline between 2028 and 2029 for full implementation. Companies must proactively plan and upgrade systems to meet the new EU regulations. These changes will affect energy storage projects across all EU member states. The regulation ensures better grid resilience with increasing renewable energy penetration.
