We warmly invite you to submit contributions on the following questions and topics:

1) Models, Scenarios, and Innovations for a Future-Proof Energy System

• Which strategies/measures are appropriate for achieving climate/energy targets?
• Which methods/models are suitable for simulating energy systems (e.g., optimization, agent-based/uncertainty models, machine learning, energy analytics)?
• How can energy and environmental policy requirements be reconciled?
• Which technical, economic, ecological, legal, and social innovations are needed in the energy sector, and how can barriers be removed?

2) Future of Renewable Energies (RE)

• How can challenges for a 100% RES energy system be met?
• Approaches to modeling RE considering weather/climate scenarios?
• Future potential for RE and solutions for dark doldrums/bright breezes?
• How can issues of land-use conflicts, ecology, and public acceptance be resolved?

3) Energy and Electricity Markets

• Causes of and measures against high energy prices (affordability/energy poverty)?
• What approaches exist for dynamic electricity prices and grid tariffs?
• How can the phase-out of gas, coal, and nuclear energy in Europe be achieved?
• How will prosumers and energy communities influence the electricity market?
• Which regulatory adjustments are necessary to achieve the targets?

4) Requirements for Transmission and Distribution Infrastructure (Electricity, Gas, Heat)

• How can security of supply be ensured in the future?
• What requirements will future grid infrastructures face?
• How should future energy system bottlenecks be managed?
• Challenges for distribution grids from prosumers, aggregators, and e-mobility?

5) Sector Coupling, Flexibility, Hydrogen, and Energy Storage

• What role will sector coupling and power-to-X technologies play in the overall system?
• How should highly flexible supply/demand be managed?
• Hydrogen in the future energy system: technical/economic requirements?
• Status and development of energy storage technologies (including long-term, H₂)?

6) Energy Efficiency, Digitalization, and Smart Energy Systems

• What importance will heat pumps and anergy networks have in the future?
• Possibilities for increasing efficiency in buildings and production technologies?
• Which approaches exist for energy management in industry, commerce, and households?
• What contributions do smart meters, smart grids, and energy communities make to improving energy efficiency and flexibility?
• How will digitalization transform the future energy sector?

7) Future Issues in Energy and Mobility

• Challenge of e-mobility: infrastructure, grid impacts, modeling, V2G...
• Requirements for batteries (e.g., cost, lifetime, efficiency, charging, environment)?
• How can GHG emissions in the transport sector be reduced (NMT, public transport, H₂, e-fuels), and what infrastructure is required?

Note: Due to the high number of participants and limited seating, a separate mandatory registration for the first evening event on 11 Feb 2026 is required at a cost of € 20!
