Beacon Project E-Energy
Paradigm Change in the Energy System
• Decentralized energy generation
• Real-time communication and
interaction between generation and
consumption
• Key role of ICT -> Smart Grids
• Centralized energy generation
• Few communication
in distribution networks
• Passive customers
• Subsidiary role of ICT
