Via Energyhack, developers and visionaries can weigh in and collaborate on a sustainable electricity supply and digital strategies for the future. The participants can develop applications and hardware prototypes and receive professional assistance from energy and data experts. The focus lies on projects that should improve social sensibility with regard to electrical grids, energy grids and the energy transition.

Using open data from the energy industry provided by Stromnetz Berlin and other partners in the scope of the WindNODE research project, the implementation of ideas is promoted and the development of solutions is supported.

To this end, WindNODE partners Stromnetz Berlin and Fraunhofer FOKUS are jointly developing the existing grid data portal ( into an open data portal together with Fraunhofer FOKUS. This portal provides detailed public data as well as private data in an anonymised and aggregated form, for instance about individual city districts or user groups. New data sources are also constantly being added, tapped into and integrated into the portal.

To promote new applications and business models, Stromnetz Berlin and Fraunhofer FOKUS organise hackathons (the “Energy Hacks”) together with the Open Knowledge Foundation, during which programmers, creative minds and young start-ups develop exciting and innovative ideas using the data provided.

In all, three hackathons were and are held between 2017 and 2020. During each event, the best exploitation concepts are awarded a prize. Particularly useful ideas (e.g. open data offers, visualisations or applications) are supported further during the actual implementation of a prototype or proof of concept. To this end, a total amount of 30,000 EUR is made available per hackathon in the scope of WindNODE.

The hackathons cover two days during which several events are planned, such as professional contributions, workshops and project works.

The next and final hackathon is planned for March 2020. Stay tuned!

The first WindNODE hackathon took place under the slogan “You Decide” on 22 and 23 September 2017 in the InfraLab at the EUREF campus.


The Energy Hack started with a kick-off event consisting of two panel discussions. Data experts, developers and researchers exchanged on the subjects of data protection and data exploitation, on the importance of exchanging information and innovations for the use of energy.

By the evening, the hackathon started, supported with data from Stromnetz Berlin, Schneider Electric, 4cast, Berliner Wasserbetriebe and Netze Baden-Württemberg. All data were aggregated in the WindNODE data portal in advance and made available to the participants for their projects and ideas.

The second day offered other events for all interested parties, in addition to the presentation of the hackathon results. Those who wanted could build a smart electric bear from a kit during the day, view the Micro Smart Grid or the Gasometer or take part in workshops of the Technologiestiftung Berlin technology foundation. There was also a presentation of the autonomous cleaning robot “Enway”.

A total of 12 projects originated during the event, from which the jury selected winners in four different categories.

The honours went to the “Strombär” team in the Energy category, the “EnergyDiversity” team in the grid category, the “EVCount” team in the mobility category and the “Tursics Hattrick” team in the infrastructure category with their project “Waste water as a service”.

The 2018 hackathon took place under the motto “Energyhack^2: energy for an efficient city”.
Like the year before, the event was held in the InfraLab Berlin on the EUREF campus, together with the Open Knowledge Foundation and the Senate Department for Economics, Labour and Companies (SenWEB) on 12 and 13 October.

The event kicked off with a keynote speech by Nicolas Zimmer of the Technologiestiftung Berlin technology foundation on the topic of "Looking beyond the horizon: energy, data and Smart City. Art, culture and diversity?” This was followed by a discussion on data policy: "Smart City without electricity is not possible - but it has to be efficient!" It mainly concerned questions regarding tomorrow’s efficient use of energy.

The hackathon started in the evening with a lecture on data visualisation. The data for the 2018 Energyhack^2 were not only provided by Stromnetz Berlin GmbH and SenWEB, but also by Berliner Wasserbetriebe and others. Within 24 hours, the participants were able to use these data to work on joint projects and make a contribution to the digital transformation.

The projects were pitched and evaluated by the jury the next day. The winning ideas included “Internet of Bears”, an open source IoT learning platform for pupils, based on the electric bear, and a data quiz “Who or what am I?”, dedicated to the question from where data originate. The jury moreover awarded several special prizes, for instance to the project of Thomas Tursic, in which an interactive simulation game for Berlin’s power grids was developed. The game deals with the functioning of the waste water pumping stations and shows which energy can be used to operate them. The game has been designed so that children can also be introduced to these questions.

The project was already developed at the Energy Hack of 2017, was further developed in 2018 and qualified for the WindNODE Challenge of Stromnetz Berlin GmbH.

Here is a link to the game.

Acquiring impulses for the energy transition with Open Data

Disclosing the data creates a large potential for innovative developments. Future visions and problem-solving approaches are created based on the data provided if they are used for further development, analysis and evaluation. Stromnetz Berlin has therefore taken it upon itself to use its Open Data platform to inspire as many WindNODE partners as possible on the subject of open data.
