Unlock The Future of Energy Through A Real-Time Price

• Join Elia Group’s Hackathon on March 26-28 Learn more

The Elia Group Hackathon is back! 

As with the previous two editions in Brussels and Berlin, we are challenging you again. Running together we go further. 


Get ready for the challenge! The pace of electrification in our daily lives is surpassing expectations while the shift towards cleaner energy sources that emit less or no CO2 has accelerated. As we navigate this transition, decentralized production and consumption of energy lights up the future in ways we never thought possible.

But here’s the real deal: To ride this wave successfully, we need to give the consumer a wide offer of energy services. Get ready to flip the switch on how you power up!


During the Elia Hackathon, you’ll be challenged on the concept of Real-Time Price.  

What’s the Real-Time Price? 

Elia Group is engaged in a major reflection on the evolution of the imbalance price, that makes it easily interpreted by the consumer and/or its Energy Service Provider and facilitate the valorization of flexible assets in accordance with the real-time system needs. This imbalance price evolution is called Real-Time Price  as Elia Group is seeking for a price that reveals the real value of energy. 

Elia Group is convinced that the Real-Time Price will play a crucial role in the success and efficiency of the energy transition. Following this, Elia Group intends to provide a clear financial incentive to energy service providers that facilitates the valorization of the consumer’s flexibility and doing so, decreases the total cost of the energy system. 

Your Mission

Your mission will be to show the tangible effects of flexible assets steered based on the real-time price. What is its impact on both the energy bill and the balance of the grid?

The result from this hackathon is the development of a prototype (or at least a simulation) for a customer-oriented product that valorizes its flexibility by steering assets based on the Real-Time Price. Final solutions will be run live at the end of the hackathon with real-time data.

Your Challenges

What do we expect:

Come up with an innovative product for the challenge you choose 
 Make sure it can handle a live, real-time scenario
 Think big: it should be scalable and useful for a bunch of customers!  




  • Awarding Criteria

    Products will be evaluated on the following criteria: 

    • Real-Time Price utilization: how effectively does the solution allow the customer to control energy costs using the real-time price?
    • Product appeal: is the product user-friendly, engaging, and innovative?
    • Technology implementation: is the product based on state-of-the art, scalable and reusable technology?
    • Scalability and impact of the solution: can the product be easily used by a wide range of customers? Is it designed to scale up to larger groups, maintaining its effectiveness and user experience? (Only for own use cases)
    • Live demo the product (prototype): bonus points will be awarded for teams that present a working prototype.
  • Which data will be provided to participants? 

    The following data will be provided to you during the hackathon: 

    • The forecasted and final Real-Time Prices
    • The day-ahead prices, as a day-ahead estimation of the Real-Time Price
    • For Challenge 1: asset and other data related to the chosen use case.

    All data is provided in Hackathon Time. The Hackathon Time is the virtual speed-up time used during the hackathon. Both historical and real-time data (in Hackathon Time) are provided.
