Clean energy networkers InnoEnergy and the European Institute of Innovation and Technology (EIT) will be hosting the Hack the Wind event at the conference in Hamburg.
Participants will work on blockchain applications for optimising hybrid systems in a challenge set by Siemens Gamesa. Meanwhile EDP Renewables has tasked entrants with optimising predictive operations and maintenance (O&M).
Teams will be competing for a share of a €20,000 prize.
Malgosia Bartosik, deputy CEO at WindEurope, said: "We are always looking for ways to make our conference better, and last year’s Hack the Wind was a brilliant way of not only giving attendees something to learn from, but of fostering innovations and creating new start-ups."
Last year, artificial intelligence company Jungle and turbine software specialists Smart Turbine Management each won €7,000.
This year’s hackathon will be held throughout the first two days of the WindEurope conference in Hamburg, which runs between 25 September and 28 September.
