energy data-X

The project

The energy data-X project is funded by the German government to establish a common data space for the German energy market. The aim is to digitally network the electricity, transport and heating sectors in a sovereign manner and to improve the integration of renewable energies. The project is a GAIA-X lighthouse project and is intended to enable innovative digital business models for all market participants. The consortium consists of partners from the energy market, the IT sector and science. The project contributes to national and European energy and climate protection policy and is funded by the BMWK over three years as part of the 7th Energy Research Program.  

Energy data-X is aimed at market players in the energy industry and enables the development of data-driven innovations in the energy sector. The data ecosystem networks across sectors with other data spaces such as Catena-X (BMWK-funded data ecosystems of the automotive sector).

The Gaia-X initiative serves as an essential basis for energy data-X. In contrast to centralized data storage, the data remains with the owner. The services of the data space are federated (decentralized) and provided jointly by many actors. An identity and trust process ensures that the actors in the data ecosystem are known and trustworthy. Access to the data space is via a connector that uses protected data connections to ensure that only the agreed data is exchanged between the parties involved. This ensures data sovereignty.

Our solutions

The energy data-X consortium demonstrates the potential added value of data spaces in the energy market in two future-oriented use cases. In the first use case, the integration of smart meter gateways (SMGW) enables optimization of grid operation. Deviations between planned and actual feed-in and withdrawal of renewable energies are detected promptly, allowing the need for compensatory measures to be estimated. In today's clearing process, it can take several weeks before such deviations can be assigned to the players.

The second use case aims to enable the balancing of energy production and consumption by using decentralized flexibility sources. As conventional power plants are being replaced by decentralized renewable energy plants, the development of flexible suppliers and consumers is becoming increasingly important. By integrating small, decentralized systems such as charging stations, battery storage units for electric vehicles and heat pumps into the data space, their flexibility potential can be used to stabilize the energy system.
