  1. Smart Grid Update Laclede Electric Cooperative Terry Rosenthal, P.E. Manager of Engineering

  2. Cooperative Profile • Lebanon, MO • Serve parts of 6 counties • 3 district offices; 120 staff • Approx 36,000 meters - varying member density - 7 per mile average • Approx 5,000 miles of line • Approx 200 MW peak load • 27 substations Own & operate distribution system on Fort Leonard Wood Army Base

  3. Smart Grid Goals • Evaluate, integrate & implement technologies to: Technology Assimilation – modernize operations & business processes – improve customer care Member Relationship • Expand strategies that strengthen relationship & Loyalty with members, communities and leaders • Develop a comprehensive long-term reliability Distribution plan for the distribution plant to ensure: System Reliability – highly efficient operations – high level of electric service reliability • Implement initiatives to: Operational Efficiency & Cost Control – optimize efficiencies – mitigate cost increases – enhance productivity

  4. Smart Grid Initiatives • AMI Meter Deployment Driving Change – Wireless system • Improve customer satisfaction – Fully deployed 2009 – 2010 • Business process efficiency • Develop accurate records and – Hourly intervals residential data for system statistics – 15 minute intervals C&I • Utilize AMI as a means to improve outage response – Remote Connect / Disconnect process – MDMS / Customer Portal Access • Use the AMI systems for improved system reporting – • Distribution Automation voltage, amps, peak demand, high usage, etc. – SCADA voltage / VAR controls • Possible Demand Response or other Smart Grid initiatives in – Down-line feeder controls future

  5. AMI System Highlights • Leverage Existing Radio Towers and Fiber Network • Member Acceptance • Data Integrations – Customer Information System (Billing and MDMS) – Outage Management System – Geographic Information System • Report by exception – Outage / Restoration – Power Quality (voltage, blinks, etc.) • Fort Leonard Wood Energy Management • Mission Critical System

  6. Wireless WAN AMI System Network Server monitors and manages network / stores & routes data WAN provides two-way TCP/IP long-range, real-time wireless coverage Sharkfins connect WAN to LAN cluster anywhere Network Server within radio range 900 MHz Meter transceivers collect LAN and relay data and WAN commands within LAN and back to WAN Support for future load control applications & DA Multiple LANS connect to WAN to support urban & rural service areas 900 MHz HAN (optional ZigBee)

  7. AMI Data

  8. Next Steps / Summary • Business Process Review Possibilities for the Future – Changes as needed to realize maximum AMI benefits • Ability to alter billing cycles • Consider different rate • Integrate to other information structures • Pre-pay option systems • Home Area Network: – Data support for other systems – DR options • Multiple utilities: – Efficiency improvements – electric, water, gas, etc. • Distribution Management • Impacts entire organization System
