  • DR – during peak times a small reduction in demand produces a relatively large reduction in market price
  • EPRI energy efficiency initiative
  • 3 Key Components to AMI Infrastructure CEA/SAP and other Core Systems 2 Way Communication Infrastructure Connecting us to the Customer Home Area Network (HAN) HAN - Totals 85% of total project cost- most for meters New smart electric meters / add gas communication modules Within the HAN, a new programmable thermostat can communicate with the meter and provide the customer the ability to participate in AC load cycling & demand response programs Enable future “smart appliances” Provides platform for Energy Efficiency programs Communications - Choice critical to support full AMI Provides foundation for Smart Grid Hybrid Solution likely – topography of Michigan Exploring many options – Meeting w/ vendors currently LAN (Meter to Collector) – RF, Wymax, BPL, PLC Backhaul – T1, Fiber, Public Wireless, BPL CEA/SAP/MDM – Plans are to build upon CEA to provide AMI capabilities Potential 1.3 billion data points created with hourly reads Need an efficient data repository (MDMS) to handle that volume Technology/Architecture only 15% total cost ….but provides critical foundation for AMI functionality & vision for future w/ smart grid Technology very new - still evolving Other utilities AMI light (PPL, WPS, PG&E, DTE) Some full AMI pilots (SCE, SDG&E, TXU and CenterPoint) Zero fully deployed Our approach will mitigate the risk of the new technology

  • Advanced Metering Infrastructure’s Architectural Impact on Enterprise Applications Wayne Longcore Consumers Energy Manager of Enterprise Architecture & Standards AMI Program Chief Architect
  • Overview
    • Vision of the future
    • Suggestions
    • Current systems
    • Data acquisition and control
    • AMI embedded in the future
    • Architectural concept
    • Our AMI architecture
  • Vision of the Future: AMR to AMI to Smart Grid Customer Outage Detection Demand Response Theft ID Remote TFTN Remote Meter Programming Load Control Price Signals sent to Customer New Rate Design AMR Automated Meter Reads AMR Capability+ AMI Smart Grid AMI Capability+ Remote detection Central and distributed analysis Correction of disturbances on the grid Optimizes grid assets Hourly Remote Meter Reads Customer Voltage Measurement Load Profiling
  • Vision of the Future: Benefits
    • More accurate, timely bills
    • Complaint reduction
    • More information available for resolving high bill issues
    • No meter reader on site
    • Improved public relations
    • Faster outage detection and restoration – including nested outages
    • Inform customers of outages to:
      • Reduce energy costs through demand response programs
      • Reduce demand charges
      • Access detailed consumption and quality data
      • See immediate results for turn-on/turn-off
    • Customer pays for actual energy used – move-in/move-out
    • Customer driven due dates and summary billing – enables SAP functionality
  • Vision of the Future: More Benefits
    • Reduces safety incidents due to fewer field trips
    • Enables environmental improvement
      • Decreased greenhouse gas emissions
      • Improved energy efficiency
      • Reduced field trips and vehicle emissions
    • Enables net metering, Plug-in hybrid cars and distributed generation
    • Aids in outage detection
    • Identifies metered accounts not being billed and meter malfunctions
    • Simplifies rate changes
    • Provides potential new revenue from value-added products, services
    • Reduces congestion in power lines – balanced distribution load management
  • Vision of the Future Requirements AMR 1 Read / Month Outage Reports On Demand Reads and Control Hourly Reads 1 / Day or less AMI Smart Grid AMI Capability+ Even finer resolution data potentially approaching SCADA of 10 seconds or less Ability to interface multiple protocols and devices 15 Min Reads 1 / Day or less Restoration Reports

  • Suggestions
    • Compare network size to Internet in mid-1990s
    • Provide more than 20 years of expandable architecture
      • Similar to Internet Protocol (IP) and Ethernet in 1980s
        • Provide a subset of features
        • Offer new infrastructure to accommodate higher speeds, lower latencies, greater capacities, enhanced features and more economies of scale
    • Ensure a secure environment
      • Greater security than business Wireless LAN
      • More than Supervisory Control and Data Acquisition (SCADA)
    • Emphasize changing technology
      • 23 years of exponential technology growth
    • Needs Collaboration
      • Economies of scale
      • Interactive energy services for customers and company
  • Suggestions
    • Computer controlled 300 MW load shed?
      • Turn-on/turn-off through AMI network
      • Home area network devices for demand response, load shed
        • Programmable, communicating thermostats, plug-in-hybrid cars and generators
    • Support smart grid direction to minimize throwaway
      • Response time and speed
      • AMI is not the only connectivity
    • Use thoughtful approach for request for proposal and installation
      • Design end to end complete process
      • Don’t build quick and dirt
      • Think about future
        • upgrades of your core business objects
