Home Display

Development and design of a device able to provide the data managed by the Electronic Meter to the home appliances (Display, PC, TV, Home automation) to:

Project description Enhance the Customers consciousness about energy consumption Encourage Energy Management inside each house Enable the load smart control Data Device Energy Services Enel Electronic Meter By 1° half 2009, the Italian Authority (AEEG) will set the procedures that every DSO shall apply

Smart Metering for Smart Grids: a key factor The Networks of the future Central and distributed resources Smart equipments and power electronics Central and distributed intelligence Seamless integration of new applications End user real time information and participation Multi-directional ‘flows’ Plug & Play technologies

Support the national / international projects focused on Smart Grid, providing skills and competences from their experience on managing electrical distribution networks

Support the regulators on defining the enabling framework for Smart Grid (e.g. incentives by the Regulators on investments)

Support standardization bodies on defining technical specifications and requirements (e.g. connection rules facilitating RES)

Special actions to manage, monitor and analyze connection of distributed generation (bidirectional electronic meter).

Smart Grids development: the DNO role Relevant actions to be performed by DNOs have been individuated to achieve the SmartGrid Vision: Actions to be performed by DNOs
