IES in Differdange: the solution
Differdange aims to cover 100% of its non-industrial electricity needs with local production by 2030, addressing challenges common to many European cities. Achieving this requires understanding energy production and demand, motivating residents and businesses, and addressing the city’s unique environmental, socio-economic, and regulatory factors.
IES Experimentation Plan to support Differdange to achieve its challenge is divided in the following 3 strands.
Engaging and Training Stakeholders
- Collaborate with the city council, businesses, and citizens to define decarbonization scenarios and data needs.
- Customize the IES Digital Twin platform to Differdange’s needs.
- Provide training and resources to stakeholders on using the platform for developing climate initiatives and policies.
Data Collection and Preparation
- Identify and assess relevant data sources, including emissions, building, mobility, energy, and socio-economic data.
- Integrate data from public databases, city authorities, and the IES platform to enable accurate decarbonization modeling.
- Ensure interoperability with existing tools like Climateview and SIGINova Enercoach through APIs for seamless data exchange.
Modeling and Simulation of Scenarios
- Build a baseline urban model for Differdange using collected data.
- Simulate and analyze various decarbonization pathways, assessing energy, carbon, and economic impacts.
- Compare results against Differdange’s climate targets, Luxembourg’s national energy plan, and science-based targets.
- Visualize results through user-friendly dashboards with key indicators like cost-benefit analysis and investment projections.
The project will empower Differdange with a tailored digital solution to plan, simulate, and implement effective decarbonization strategies, enabling the city to meet its ambitious sustainability goals while engaging its community in the energy transition.
