EASE has prepared a short summary on one of the following energy storage application groups - Services to Support Transmission Infrastructure.

Services to Support Distribution Infrastructure
The Task Force on Segmentation of Applications has developed the Services to Support Distribution Infrastructure Report, among other application descriptions. This work builds on the Summary of Energy Storage Applications published in June 2020.
This overview provides a summary of different energy storage applications that can provide alternative or traditional grid infrastructures at the distribution level. As the variable renewable energy sources are deployed regularly, these emerging services are gaining importance on the EU Market.
Services to Distribution Infrastructure are composed of six key systems:
Distribution Grid Upgrade Deferral: using energy storage to defer or avoid distribution infrastructure upgrades and solve distribution congestion issues by installing energy storage systems instead of new lines; using energy storage as a distribution grid component to decrease the traditional grid size during the grid planning process by basing its design on a medium power value and not a peak power value.
Contingency Grid Support: using energy storage to perform some capacity/voltage support in order to reduce the impacts of the loss of a major grid component. It refers to redundancy provisions to cover the trip of the largest transmission line in an area.
Dynamic Local Voltage Control: using energy storage to maintain the voltage profile within admissible contractual/regulatory limits.
Intentional Islanding: using energy storage to energise a non-loopable feeder during an outage.
Reactive Power Compensation: using energy storage to reduce the amount of reactive energy drawn from transmission and charged by the TSO to the DSO.
Cross Sectoral Storage: the practice of coupling the electricity sector with other energy sectors (gas, fuel, heat) by converting excess supply of electricity to the grid into energy carriers, synthetic fuels, and heat, thus avoiding curtailment of running power generators (RES, thermal power plants, etc.).
EASE has responded to the European Commission's Public Consultation on 'Renewable Energy Projects - Permit-Granting Processes & Power Purchase Agreements . This initiative aims to facilitate renewable energy production projects. It will focus on the key barriers to implementing renewable energy projects and outline good practices addressing the identified barriers and good practices to facilitate power-purchase agreements, including across borders.
EASE has responded to the European Commission's Public Consultation on the proposal for ‘Hydrogen and Decarbonised Gas markets’ Package. This Package, consisting of a review of the Gas Regulation and of the Gas Directive, aims to decarbonise gas consumption, and puts forward policy measures required for supporting the creation of optimum and dedicated infrastructure, as well as efficient markets.
The revisions of the Energy Performance and Buildings Directive and the Energy Efficiency Directive are vital to achieving a zero-emission and fully decarbonised building stock and a carbon-neutral energy system by 2050. EASE welcomes these revisions as an opportunity to speed up decarbonisation efforts through the efficient and optimised use of energy. However, stronger integration of energy storage solutions is required.
EASE has prepared a position paper on the Renewable Energy Directive Revision (REDIII) highlighting the great opportunity this review offers in terms of speeding up decarbonisation efforts in the energy system. EASE believes energy storage can be fostered through RED III in multiple ways.
