Smart Cities are calling for a major innovation in many strategic infrastructures that shape the daily life of citizens. Arguably one of the most strategic and resilient to changes is the power transmission and distribution infrastructure. And yet, the power sector, together with the communication network infrastructure, are the major enablers of future smart cities.In this paper, we present three fictional, yet likely use cases that highlight how the Information and Communication Technologies (ICT) and Infrastructures are ready to support this much needed innovation, while the power distribution infrastructure has still a long way to go to be able to benefit from the opportunities offered by ICT. The resulting discussion will hopefully involve power grid operators and legislators to the end of promoting a thorough renovation of the power sector.
