Participation at 2022

The will be hybrid:

  • is a marketplace for a new way of tendering: You have the chance to win follow-up contracts in total over 40.000€ by the challenge-setting companies. If there will be no follow-up contract the first place wins 4.000€ and the second 1.000€ in prize money (only TransnetBW challenge)!

  • Registration is completely free!

  • The starts with a virtual kickoff on 09.11.2022 12:30 CET. From 15.11. to 18.11.2022 you have the opportunity to come free of entrance fee to the EuroTier/Energy Decentral Summit (Hannover, DE) and continue working on your prototype at our booth.

  • You don't have to be onsite the whole trade fair or virtually available the whole time, but on your finals day (see below)! On the morning of the finals day there will be an individual concept discussion with you and the challenge company (approx. 30min) and at noon your pitch (approx. 5-10min).

  • You can still apply after 09.11.2022, but of course, your working time will be shortened then: Finals will be on the 16th (TransnetBW)/17th (Fraunhofer) of November 2022 on the stage.

  • Max. 10 teams of five people each may participate, whereby - depending on the respective regulations - at least 3 members per team will be granted free access to the EuroTier/Energy Decentral (on-site).

  • Teams can also participate completely virtually.

  • Communication with other team members and other participating teams will take place in a separate infrastructure via the network (off-site).

Win overall follow-up contracts over 40.000€ or 5.000€ in prize money! 2022 - The Challenges

TransnetBW challenge - Energy System 2050

You can pitch your results either onsite or virtually on Nov 16.

In the Energy System 2050, the demand for flexibility will increase strongly because generation will be largely from renewables and thus volatile and not controllable. This requires a controllable electricity demand that can follow the supply.


The main goal of the challenge is the identification and evaluation of possible business cases for the provision of vehicle-to-grid (V2G) services by private e-cars owners, i.e. under which conditions (economic, technical constraints) private citizens are assumed to be willing to offer this flexibility service to the grid, and which incentives should be put in place in order to mobilize such flexibility potential.

In addition, an assessment of a trade-off between the cost of participation to V2G on the one side and need for alternative flexibility options (e.g. stationary batteries, grid reinforcement) on the other side should be analyzed.

Your impact

The results are used for studies on-demand flexibility and the development of new flexibility products. TransnetBW is looking for new service providers and employees. Provide a running prototype plus a budget plan for a first follow-up contract worth 20.000€ or prize money worth 5.000€! So this is a call for an offer for the first place!!

Fraunhofer challenge - Optimize daylight harvesting systems

You can pitch your results either onsite or virtually on Nov 17.

Since irregularities occur due to various work in the barn, we want to install an animal welfare-friendly daylight harvesting monitoring system in a chicken barn through Computer Vision. Daylight harvesting systems use daylight to offset the amount of electric lighting needed to properly light a space, in order to reduce energy consumption. This is accomplished using lighting control systems that can dim or switch electric lighting in response to changing daylight availability.


Analysis of the potential in daylight harvesting of the future chicken-friendly barn demand.


Due to the natural rather dim environment, the eye of the poultry has adapted. Daylight that is pleasant for humans is often too bright and discomforting for poultry. On the other hand, the birds can see less well at night, so a barn that is too dark leads to poor orientation and thus less feed and water intake. Therefore, it is important to have a lighting programme that optimally fulfils animal welfare needs. The lighting programme can influence movement activity, feeding behaviour and feather pecking. Sufficient lighting and light promote health and encourage the broilers to grow healthily. Ideally, the barn has sufficiently large windows because it is not always possible to give the animals free access. Then it is good if sufficient daylight enters the barn.

Your impact

The results are used for studies on the development of new daylight harvesting systems. Win a follow-up contract based on your prototype and 100-days-MVP-concept!
