The six cities involved in the project will go through a Pre-Commercial Procurement (PCP) process. PCP is an innovation procurement tool to stimulate market innovation as it enables the public sector to steer the development of new solutions directly towards its needs. The six cities will define the needs and requirements of the energy and mobility solutions to be developed, and challenge start-ups, SMEs and companies to design innovative solutions applying the use of AI and related enabling digital technologies, such as 5G, Internet of Things (IoT), cloud computing and big data applications.
