Buddy Power with Caruna

Congratulations to the six teams selected to the Buddy Power challenge!

Caruna is the largest electricity distribution company in Finland, with approximately 20% share of the local energy distribution market. Their customers can generate electricity for their own use and sell the surplus through Caruna's network. Now, through this innovation challenge, Caruna is looking for external solver teams to define and develop services for small energy manufacturers, households and communities around them.

What are the ways to buy excess energy from your neighbour manufacturers, e.g. facilities generating bio energy and households that accommodate solar cells? How can one sell the excess energy in their local communities, in a way that is transparent, easily accessed and free of extra cost? What would be the business incentive and what kind of platform could be used?

Available Resources

To help the development of proof-of-concepts during the challenge, we have reserved some key people and resources to support your work.

Mentors & Experts

Each team will be assigned with their own mentor from the host. There will also be other industry and service experts from the host to help teams with their work.

Data & software

Information, knowledge and data on energy consumption, electricity distribution, excess energy usage is given and shared by Caruna to the challenge participants.


  • Applications close – September 20th

  • Applicants informed about the selections – September 28th

  • Challenge kickoff visit (mandatory for all teams) – October 10th (afternoon - evening)

  • Co-development Camp (mandatory for all team members) – October 31 - November 1 (all-day event)

  • Pilot phase kickoff workshop (mandatory for best teams chosen by jury) – Mid November

Estimated time commitment

The teams are expected, in minimum, to work full-time on the challenge during the co-development camp (2 days), take part in kickoff visit (0,5 days) and invest an estimated 1-2 day per person of their time in working on the idea between the kickoff visit and the camp, also together with their assigned mentor.

After the Camp, the chosen innovation partners are expected to work on their pilot project (building and testing an MVP) and take part in 2 workshops (kickoff and finalization), and the final jury presentation to discuss the final proposal for collaboration. The latter two events will be scheduled in the pilot kickoff workshop.


The teams compete for pilot projects worth ~20 000 euros. Each participating team will be paid a reward of 1500 eur. Rewards are paid against invoice after the team has presented their demo and the customer has made the decision about the pilot.


Apply with a team of 2-3 people. All applications will be reviewed after the deadline and all applicants will be informed after the deadline. 6-8 teams will be selected to join the challenge.

During the challenge the selected teams will develop and conceptualise their suggested solutions together with Host’s mentors. The aim of the competition is to find one to three solution suggestions that can be further tested in real environment in the piloting phase.

Who will own my idea?

Ideas are free for everyone to use but the IPR for any software codebase or documents produced during the competition will stay with the team. The host has the first right of refusal to negotiate further collaboration with the team to purchase or continue working on the project initiated during the challenge.

What is the regulatory framework for the peer-to-peer trading? Current or is it part of the idea to propose changes?
Eeva Siika-aho7 months ago
Hi Leena! Very good question! The current regulatory model does not consider peer to peer networks at all, effectively meaning they're not supported. The purpose of Buddy Power is to identify potential solutions for showcasing peer to peer networks, in order to create a positive regulatory environment for their take-off.
