2. A small chip a big change in energy efficiency What is the Smart Grid The Smart Grid is a developing network of transmission lines, equipment, controls and new technologies working together to respond immediately to our 21st Century demand for electricity Smart Homes & Meters Distribution Intelligence Grid Operation Centers Renewable Energy Plug-In Electric Vehicles Consumer Engagement

3. A small chip a big change in energy efficiency What Makes a Grid “Smart?” digital technology that allows for two-way communication between the utility and its customers sensing along the transmission lines Like the Internet, the Smart Grid will consist of controls, computers, automation, and new technologies and equipment working together

4. A small chip a big change in energy efficiency What does a Smart Grid do? The Smart Grid represents an unprecedented opportunity to move the energy industry into a new era of reliability, availability, and efficiency that will contribute to our economic and environmental health. The benefits associated with the Smart Grid include: More efficient transmission of electricity Quicker restoration of electricity after power disturbances Reduced operations and management costs for utilities, and ultimately lower power costs for consumers. Reduced peak demand, which will also help lower electricity rates Increased integration of large-scale renewable energy systems Better integration of customer-owner power generation systems, including renewable energy systems Improved security

5. A small chip a big change in energy efficiency Challenges for the implementation of a Smart Grid Hundreds of million of devices will be connected Power Generation Metering devices Sensing devices – Outage detection Static Power consuming devices ( Industrial, Commercial, Consumer Appliances) Mobile Power consuming devices ( EVs ) Etc… How do we manage all of this ?

6. A small chip a big change in energy efficiency Need for a Smart Electricity Network Integrated communication infrastructure that enables near real time, two-way exchanges of information and power AMI that record and communicate detailed information about energy usage Sensors and monitoring systems that check the flow of energy and performance of the network’s assets Automatic controls that detect and repair network problems Advanced infrastructure that improve network performance IT systems with integrated applications and data analysis

7. A small chip a big change in energy efficiency The need for Distributed Intelligence 7 No real time feedback on usage Largely based on modelisation Not yet smart Need to be educated The Smart Grid will allow the customer to participate in the market: Benefit from dynamic pricing Managed their power consumption Resell micro generated power Store and give back power ( PEVs)

14. A small chip a big change in energy efficiency Communication Technology for the Smart Grid PLC vs Zigbee Zigbee was designed for in-home applications starting from a start type network for small number of nodes to create a big network it requires to add coordinators and routers which are power consuming. PLC support bigger network with less cost. PLC network is created with the structure of electrical cable and support a higher number of nodes without extra cost and penalties on the data rate and much less power. Router PAN coordinator End Node Zigbee Network
