Technical aspects
The objective of the data exchange demos is to test more than 20 data management
use cases facilitating flexibility services as well as many other business processes. Several demonstrations will focus on aspects of data management, including cross-border communication between different data exchange platforms and with different stakeholders in order to facilitate the cross-border exchange of flexibility services with the following elements:
• Cross-border data exchange between different stakeholders – system operators, market operators, end customers, data hubs, service providers, etc
• Handling of personal and commercially sensitive data
• Affordable application for smaller distributed DSR
• TSO-DSO flexibility data exchange application
• User interface – single access point to data, services and applications
• Combined access to metering and operational data
• Cross-sectoral data usage
• Big data collection, storage, processing
• Cyber security and data privacy requirements

Elering’s data exchange platform, Estfeed, will be used to demonstrate data exchanges. Estfeed connects various data sources, applications and market participants. It provides secure access to consumption and generation data in the electricity and gas data hubs.
When developing data exchange demonstrations the aim is to ensure they fit with the Smart Grid Architecture Model, Common Information Model and Harmonised Role Model.

Innovative aspects of the demonstration
• Customer-centric cross-border data exchange model for flexible market design serving all stakeholders (TSOs, DSOs, suppliers, flexibility providers, ESCOs, etc.).
• Interoperability of different data exchange platforms.
• Application for flexibility marketplace to support TSO-DSO flexibility data exchange.
• Tool for aggregator to aggregate smaller distributed flexibility sources enabling affordable access to market

Main challenges
Data exchange demonstrations are designed to tackle access issues. First, more or less any business process in the energy domain requires easy and secure access to data and facilitation of data sharing in line with the Clean Energy Package and GDPR principles. Second, and more specifically, market access for smaller flexibility providers has to be considered as they may face barriers like high initial investments and lack of single market places. Further challenges involve TSODSO cooperation and coordinated actions as well as neutrality of system and market operators.
