Tender CHALLENGES / Differdange

Differdange has set the goal of producing locally and sustainably 100% of its global need in electricity by 2030 with the support of its population. Data and IT platforms are essential to translate the relevance of our long-term goal to the general public, and in order for the Municipality to better understand the potential of renewable energy in the city and its carbon accounting profile.

In fact, IT platforms can enable better data visualisation, comparison of future scenarios and screening of the city’s existing infrastructure that could support the development of investment options in renewable energy solutions for the citizens.

Envisaged solution

Differdange is looking for a socio-technical systems based on IT platforms that allow the city administration to better engage with available data on energy in order to increase its leverage and credibility when promoting renewable energy production options to both citizens and industry. Data visualisation solutions that streamline ongoing developments and allow future simulations to be envisaged. In addition, the solutions should take into account the diverse and multilingual character of the population and the peculiarities of the industrial sector operating in the area.

Information on the location of the experimentation

The whole territory of the municipality of Differdange  measuring 22,18 km2, situated in the south of Luxembourg bordering France and the municipalities of Pétange, Kärjeng and Sanem.

Differdange City Map

Specific requirements

  • Solutions that promote datasets creation, including data acquisition by IoT sensors and the collection of real time waste data
  • Solutions that allow relevant data visualisations, both for remote monitoring purposes and to improve decision making
  • Solutions that integrate created datasets and embed visualisation functions in a single tool;
  • Solutions that embed gamification and/or educational aspects, such as general or specific advice on how to improve waste selection, understand data visualisations, etc.
  • Solutions that are promptly available as applications (for smartphones and tablet PCs, on Android and/or IOS operating systems).

Minimum requirements

Data usage

The solution should at least rely on the following datasets: Energy consumption / production, Existing Infrastructure, Socio-economic Data, Carbon Emission Data, Engagement Metrics, Policy and Regulatory Data

Data acquisition

The provider should at least acquire the following datasets: Trends on Energy Data, Potential of energy production (heat and electricity), Technological Data, Public Opinion Data.

Data availability

The provider should at least use the following datasets made available by the City: Existing Infrastructure, Energy consumption / production, Socio-economic Data, Demographic Data, Policy and Regulatory Data

Data generation

The solution should at least generate the following datasets: Comparative Emission Data, Scenario Simulation Results, Economic Indicators, Community Participation Metrics, Regulatory Compliance Data, Trend Analysis, Carbon Accounting Data.

Data visualisation

The solution should at least enable visualisation of the following datasets: Scenario Simulation Results, Economic Indicators, Energy Transition Metrics, Emission Reduction Data, Trend Analysis.

Socio—technical solution A

The active engagement of citizens should at least be ensured during the 12 months of experimentation.

Socio—technical solution B

The way active engagement of citizens will contribute to a better performance of the solution should be described in detail.

Socio—technical solution C

A minimum number of 200 citizens should be engaged by the provider during the 12 months of experimentation.

Socio—technical solution D

The solution should at least demonstrate impacts on the following citizen behaviours: awareness of sustainable investing options.

Socio—technical solution E

The provider should at least involve the following local stakeholders during the 12 months of experimentation: industrial partners, citizens, banks.


The solution should at least be interoperable with the following existing IT systems: MS Office, Climateview, SIGINova Enercoach, Luxembourg Institute of Science and Technology Digital Twin.


Use of the solution should not imply the release of personal data unless for specific and motivated purposes.


The provider should specify how the solution can be scaled from the site of experimentation to the broad City level” bearing in mind that priority will be given to solutions that can already be deployed at City level.


The provider should specify the conditions under which the same solution can be adopted by other Cities with similar challenge.
