Wien energie Challenge


Energy and Grid, Photovoltaic power generation, energy demand and supply management, predictive maintenance, energy modeling and prognosis, Smart cities, Smart Buildings, citizen empowerment



Aspern Smart City Research GmbH & Co KG (ASCR) is a joint venture between a network operator, an international technology company, an energy generation and supply company, and the City of Vienna. This partnership was established to develop and test the technical solutions required for future energy environments in new urban districts. The fundamental goal of energy transition is the reduction of CO2 emissions; however, this must be achieved whilst ensuring the provision of a fail-safe supply of energy. The testbed Aspern Smart City Research focuses on energy management, smart buildings, smart grids, smart ICT and smart users. To optimize the utilization of energy, technologies and consumption, an integrative system approach is used.

World Smart City Award: ASCR was identified as the world’s best Smart Project 2016. It prevailed against more than 250 projects from 45 countries at the Smart City Expo World Congress in Barcelona, the world’s largest event on the subject of smart cities. Following the success of the first phase (2013-2018), the project has been extended for a further five-year run (2019-2023) with a budget of 45 million Euros.





We are looking for innovative ways to exploit the full potential of the monitored energy supply and demand data, as well as the FIWARE IoT platform for smart energy management and maintenance.


Connecting three existing systems to the FIWARE platform.


  • Real-time data transmission
  • Secure data transmission
  • Data caching, in case of transmission interruption
  • Retrieving data when the data connection has been re-established


  • BürgerInnen-Solarkraftwerk Rosiwalgasse 500kWp
  • PV-Anlage MA28 10kWp
  • HausMaster-Pilotkundenanlage
  • Logic Machine Ambient

  • Algorithms for data plausibility checks (detection of outliers and data gaps)
  • Algorithms for the correction of outliers, as well as strategies for the replacement value formation with data gaps
  • Alarm visualization
  • Determine, calculate and clearly visualize system parameters (e.g. performance ratio)
  • Prognosis of the expected PV production on the basis of global radiation data of the irradiation sensor of the plant and determination of the deviation from the actual production of the plant, including alarm message in case of deviation

Important! As FIWARE ICT Challenge Vienna is a side event of ICT 2018, all applicants must be registered for ICT 2018. Online registration is closed now but you can still register in person at the venue of ICT 2018.



The presented challenge concentrates on smart demand and supply management. We are looking for innovative ways to exploit the potential of the monitored Photovoltaic supply and building-level energy demand data towards efficient management of distributed energy generation systems. Interesting themes include (but are not limited to) data-oriented fault detection and predictive maintenance, user-behavioural pattern recognition, data-oriented identification of improvement potential and performance maximization, data visualization and inhabitant empowerment. The first prototype applications and proof of concept implementations are to be presented and tested, at the end of the challenge.


  • Real time energy output data from a citizen solar power plant (BürgerInnen Solarkraftwerk)
  • Real time weather data, including local irradiation values Technical description of the data collection process and access to the relevant gateways
  • Real time energy use data, energy saving potential of a customer (connected to the same solar power plant)
  • Historical data of building-level energy use data (disaggregate values for heating, warm water and electricity) (real-time value simulation possible) (data resolution, period, more info)

Additional Open Data of the City of Vienna in various formats (


The winning team will be awarded with a 3000 Euro grant. An additional offer of collaboration with ASCR in form of internships and research projects may be extended to participants with exceptional ideas.

Use the most advanced protocol stack, FIWARE Context Broker and NGSI (more information on A catalogue of FIWARE components can be found on Your application should run on the datalake where you will access all data from Once applied, you will get access to the FIWARE node that runs this address. The usage of the FIWARE Lab will be an advantage (see Access FIWARE tutorials –


The submitted proposals will be evaluated based on the following criteria:

  • Innovative quality: ideas will be assessed with respect to originality and relevance.
  • Market relevance: ideas will be evaluated in view of market benefit and implementation potential.
  • Technical relevance: the proposed solution must make extensive use of FIWARE technologies. FIWARE
