4 Global Energy Issues Worldwide energy demand will rise to over 30,000 billion kilowatt hours by double what the world was using in International Energy Agency In next ten years the US will have to build 160 large power stations just to meet domestic demand - North American Electric Reliability Council By 2025 there will be 2 billion more people on planet Earth energy demand will rise by 54% - US Government It is estimated that failures within the grid such as blackouts and power interruptions, cost the American economy in excess of $100 billion per year The August 14, 2003, blackout that affected the area from New York City to Detroit impacted the lives of 50 million people and cost an estimated $6 billion. - GridWise Alliance

5 European problem as well Nov 2006 Overload in the power network in Cologne, Germany triggered outages which spread across Europe... France 5M affected in Paris Italy Piedmont, Ligura and Puglia Spain Madrid, Barcelona, Zaragossa Also impacted Austria Belgium Netherlands Croatia Chaos - "We weren't very far from a European blackout," a senior director with French power company RTE said.

6 What are the proposed solutions? Reduce demand Double world energy supply Discover alternative energy sources Improve energy efficiency Manage demand better Do nothing

7 What is Advanced Metering Infrastructure? Advanced Metering Infrastructure (AMI): Intelligent" technology that includes metering systems capable of recording and reporting energy consumption and other measurements at more frequent intervals than the customer's billing cycle (generally monthly). AMI may encompass several different components: meters, communications technology, automated meter reading systems, and data warehouses. It provides the foundation for consumers to make informed choices about energy usage based on the price at the time of use. New York State

8 What is ZigBee? RF Networking with Embedded control Open and interoperable global standard 2.4 GHz is a license free ISM band, available Worldwide Multiple vendors and user defined open standards

9 How does that help? ZigBee is to home and building automation what Bluetooth is to a GSM phone or PC It can form the backbone control and sensor network for buildings It can form a reliable Personal Area Network that has sensor, control and low bandwidth data communications It can work seamlessly with other networks such as WiFi, Broadband Ethernet and GPRS via a low cost gateway It s wireless so ideal for new and old infrastructures Whilst not designed to be a point to point system it can be used as a basis for one that will scale over time ZigBee can t Play music or video or run broadband

10 ZigBee Application Layers Stack + Application Profile = Ease of Development and/or Interoperability Commercial Building Automation Home Automation Industrial Plant Monitoring AMR / AMI ZigBee Home Automation Profile describes: Devices: Thermostat, Light Switch Messages: Set Point raise/lower, Pump Start/Stop, etc Commissioning and Joining Advanced: supported stack profiles, custom extensions

11 ZigBee The Technology ZigBee provides an open wireless standard for the HAN [Home Area Network] enabling device networks in the home for load control Heating/AC, Security, Lighting, Appliances. AC Water Meter Gas Meter

Spontaneous reading Turning meters on and off Controlling Current Controlling Voltage levels Registering power failures Triggering power failure alarms Load control Reporting other alarms eg flood, fire Controlling and managing customer equipment

20 Real-time power management Using AMI systems you can derive real-time data on power use and power cost for all parties This enables the consumer: To make real-time decisions on energy consumption To devise a domestic energy strategy based upon price paid To take an active part in reducing energy consumption Trials show 3% - 11% reductions where access to daily consumption data is allowed This enables the energy utility: To make real-time decisions about power supply delivery Based on who used how much of what, where and when To manage power distribution To minimise power cuts and outages because system can be smart, self optimising and self healing
