Conclusions
• 5D’s (deregulation, de-carbonization, decentralization, digitalization and depopulation) will be triggers for the transformation to Utility 3.0.
• Future power systems will play a key role in realizing Utility 3.0 as an integrated platform with other network infrastructures, energy & market management, and integrated data management.
