External stayKey points
• 4 Months - Mid April to mid August
• Contacts: Nicole Pini & David Eyler
• Franco-German research effort
• Energy resources % decentralized production
• Worked on the MAGNITUDE project (originally was anotherproject)
• Writing a white paper

External stayMAGNITUDE
”Bringing flexibility provided by multi energy carrierintegration to a new MAGNITUDE”
• Focused on flexibility services provision to theelectrical grid through MES
• Enhanced business and market mechanisms
• Seven real life case studies of MES of differentsizes and technological features
• Propose recommendations and contribute to thedefinition of policy strategies at EU level.

External stayMAGNITUDE
Involved in WP1 and WP4
• WP1: Case studies and system configurations
• Gather data and information about CS
• Services identification
• Constraints and bottlenecks
• WP4: Modelling
• Use case expertise
• Technologies fact sheets
→ Higher level focus than my PhD project

White paper
Gaps for large deployment of power-to-heat units in the heatsector
• Nicole: top-down approach
• Thibaut: Bottom-up approach
Existing DH systems
- Network- Heat supply technologies- Consumers behaviour- Buildings

White paperGaps - main findings
Several type of gaps: Regulatory, Technical, Operational, Type ofdeployment
• Regulation biggest barrier
• Pricing
• Ownership
• Sophisticated monitoring/metering
• Design (system integration)
• Connection (R/S, S/S, R/R ...)
• HP are sensitive
• Control, maintenance, collaboration on deployment type
