ETIBLOGG is short for Energy Trading vIa Blockchain-Technology in the LOcal Green Grid. The research project therefore aims to develop blockchain-based solutions to make trading with even the smallest amounts of energy more efficient and most of all faster.
By working on this project, eight partners out of research or economy come together. Furthermore, ETIBLOGG is supported by the Federal Ministry for Economic Affairs and Energy, Smart Service Welt II, DLR Project Management Agency and the Institute for Innovation and Technology.

With our mobile demonstrator “Edi” we have shown that the blockchain device enables both decentralized, real-time trading and the control of various systems. We are currently preparing everything to implement the previous findings from ETIBLOGG in a public demonstrator for a special use case. This means that there is currently no ready-made solution that can be immediately installed in various systems. We are certain that in the course of the year, by implementing ETIBLOGG in an almost public network, we will be able to gain further insights in order to be ready for use in various use cases.
This is the intersection, where every player in the system can participate. Therefore, there is a blockchain device for each actor in the local grid. Among its tasks are:
- Control of the connected plant
- Configuration of user trading parameters
- Energy trading in the P2P network
- Blockchain access
In a peer-to-peer-network (also known as p2p) every participant has equal rights. This means, there is no central point where every information comes together but the involved persons communicate directly. In the example of ETIBLOGG, the energy trade from the producers blockchain device works directly with the consumers blockchain device.
After an extensive search and thorough evaluation of several blockchain Frameworks, we concluded that PONTON’s WRML ® (read „Wormhole“) is best suited to support ETIBLOGG’s use case. WRMHL is a GDPR compliant, enterprise ready blockchain framework built on JAVA technology, which makes it easy for users to integrate end-to-end business application utilising blockchain technology. It provides a modular architecture separating the application and infrastructure layer, which is based on the Tendermint consensus mechanism.
You can learn more about WRMHL in the published white paper from our ETIBLOGG partner PONTON: https://www.ponton.de/products/wrmhl/
Sensitive data is handled in the ETIBLOGG case, a private blockchain is preferred to the public one. More precisely said, the ETIBLOGG case is in the form of a consortia blockchain in the moment. The WRMHL used supports consortia blockchains with a certain number of Validator Nodes.
The ETIBLOGG trade fair demonstrator is a mobile model system that represents a microgrid made up of local participants. Their pro- and consumption behavior is simulated by using three battery systems including converters within the fair demonstrator. One battery assumes the role (of a PV system for example) as a producer, another a consumer, such as a bakery, and the third battery a classic prosumer with home storage. In order to carry out real-time energy trading via the blockchain, fully automatic trading agents are used that can be configured individually and represent one market participant based on these usage preferences. Trading then takes place via a blockchain-based P2P network. After a commercial transaction has been carried out, the BCD initiates a system control and thus the physical exchange of electricity between producer and consumer.
SCADA is short for Supervisory Control and Data Acquisition, which description already explains the main use of These Systems very well. With SCADA-Systems, a Company can regulate its plants and collect business-based data.

The distribution of load can be divided into three parts: basic load, mid-load and peak load. The basic load is the usual network load, which is always given and should not be undercut. The mid-load means the amount of electricity, which is needed on daytime. The peak load describes those peaks, which only happen suddenly but only last for a short time.
Balance energy means the difference between the estimated use and the actual use.
Primary energy is the amount of energy, which is available via the natural energy source. Secondary energy is another form of energy and differs from primary energy. It is formed via a transformation process to make the energy easier to transport or use. The kind of secondary energy, which reaches the end user after waste during transportation and transformation, is called final energy. But even from this only a small amount of energy is used for the purpose we wish for – this amount is called effective energy.
This is a question which we cannot answer at this time, even though it is already an important aspect. But to get an insight in the consumers and poducers preferences, we ned experience which we can only gain after a certain time.
