The project includes the installation of approximately 8,000 devices in order to increase the participation of the end user to the electrical system and promote an efficient use of energy; it gives the customer readable information on energy consumption and provides home controllers with data for load management (home automation)

Smart Info is based on Enel remote metering system activated more then 10 years ago, on the whole national territory: • plugged into one of the house electricity sockets; • univocally associated to customer’s own meter; • makes consumption or generation data available.

14 Uso: AZIENDALE Isernia Project Smart Info: Main functions of Enel Info+

ANALYSE: Smart Info Manager SEE: Smart Info Display “SEE” plus: • Current, historical, tendency • Detailed analysis of load profile consumption • Comparisons in time • Tariff time bands notification • Comparison generation vs consumption • Power/Consumption limits • Energy efficiency suggestions monitoring • Contractual data visualisation • Messages from SO • Extra information (date, hour…)

EXPLORE: Smart Info Mobile “SEE” + “ANALYSE” accessible from a smartphone

Data Analytics Uso: AZIENDALE Isernia Project Enel Info+: 2013 activities • Progress: 3300 households recruited (~30% of the invited households) • Forecast 2013: 4500 households • Project launched in 19 towns with dedicated events

Unexpected component costs:

• Telecommunication (LTE, Optical fibre, Routers, and switches); • IRE interface.

Difficulties and time consuming activities: Enel Info+ Kit

• To involve producer and to equip their plants; • To involve people in Enel smart info trial; • To involve the main European producers of inverters; • To obtain permission for PV power plant.
