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 published its 2022 Activity Report. In 2022, safeguarding our Energy Security became an urgent priority, underscored by geopolitical instability and the increasing pace of the climate crisis. At EASE, we have continued to push for the deployment of Energy Storage, which is key to secure an independent access to energy, whilst paving the way for a carbon neutral economy.
EASE has responded to the European Commission's Public Consultation on the Revision of the EU’s Electricity Market Design. This initiative aims to review the current electricity market design and identify areas for improvement that could support the integration of renewable energy sources, while ensuring security of supply and keep prices affordable for consumers.
On 7 December 2022, over 200 participants attended webinar on electricity market design revision and joined the discussion on how it can enable energy storage for a carbon-neutral future. Representatives of EASE Policy team presented the latest EASE policy analysis paper "The Electricity Market Design Revision" and shared a list of changes identified to ensure a renewable-based and secure energy system. Speakers from Iberdrola, CellCube, Fluence and Enel X joined to discuss the topic.
EASE has finalised a paper on the upcoming electricity market design revision, highlighting how energy storage can enable a carbon-neutral future. More than ever, energy independence, security of supply, sector integration, and decarbonisation are guiding policymakers’ actions. EASE identifies a list of changes as needed to ensure a renewable-based and secure energy system.
