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.

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
