Energy Storage Technologies are Essential to Decarbonisation: Revision of the Climate, Energy and Environmental Aid Guidelines
EASE welcomes the revision of the Climate, Energy and Environmental Aid Guidelines to align the State aid framework with the EU’s ambitious decarbonisation targets and the European Green Deal. With the revision of the EEAG, the EU seeks to address challenge of ensuring a clear framework that supports decarbonisation in a cost-effective manner while maintaining competition and fair trade.

Services to Support Transmission Infrastructure
The Services to Support Transmission Infrastructure Report is one of the applications' descriptions elaborated by the Task Force on Segmentation of Applications. This work builds on the Summary of Energy Storage Applications published in June 2020.
This overview provides a summary of different energy storage applications, focused mainly on the electricity system. The transmission infrastructure services are ones that energy storage could provide as an alternative or complement to traditional transmission infrastructure assets.
Services to Support Transmission Infrastructure are composed of three key systems:
- Transmission Investment Deferral: deferring transmission infrastructure upgrades and solving transmission congestion issues by installing energy storage systems instead of new lines.
- Angular stability: use of energy storage to charge and discharge high levels of energy in short periods when an accident occurs, overall improving angular stability of the system.
- Transmission Support: use of energy storage to improve the performance of the transmission system by compensating for electrical anomalies and disturbances such as voltage sag, unstable voltage, and subsynchronous resonance.
