Smart city projects are at the crossroads of technology, infrastructure, financing, construction, environment and energy. As a regulated sector, the energy supply is certainly paramount when it comes to making smart cities a successful, viable and sustainable project. This session will address the challenges facing the energy supply of these modern and connected cities. In particular, this panel will discuss how regulators and government agencies have or should legislate in this area to create a favourable regulatory and legal environment, and how energy suppliers have or should provide secured and efficient energy supply, and hence play their role as the main sponsors of future smart city projects.
