Within the GrowSmarter project, the infrastructure’s architecture is composed of four main layers. Field components cosist of meters (electrical, gas, water, heating, cooling), urban and environmental sensors, data Hub, composed of an MSC installed at the secondary substation, platform and energy Services and Apps.The MSC installed at the secondary substation is the central element that collects data from the different field components and then transfers it to the GrowSmarter Platform through a central system (Endesa Platform). This data will be managed through the Growsmarter Platform and will offer some added value energy services as for example to monitoring consumptions, to managing street lightings,… allowing an improvement in energy efficiency. Other agents such as ESCO (Energy Services Providers), retailers, aggregators, customers, etc. will benefit from the new information collected.

The main communications technologies supported are:

• Radiofrequency (RF) based on wireless M-Bus protocol, used for communication between the concentrator and gas, water and heating meters.It would be also used for the communication between the concentrator and wireless sensor network (WSN).
• PLC (Power Line Communication), used for communication between the concentrator and electrical meters. PLC would be also used for public lighting monitoring.
