  2. OVERVIEW • Introductions BREC at a Glance • Background of Linux at BREC • Description of BREC EMS • Operating Systems - Servers and Workstations • Benefits of Linux and Windows • Benefits of Vendor - Open Systems International Inc. • Caution for any EMS System Owners • Questions - Comments

  3. Who Is Big Rivers? • G&T Cooperative, Formed In 1961 • Generating Capacity Leased To LEC Through 2023 • Owns 1,459MW Net • Leases 217 of 312MW Net • LEM PPA: 597MW through 2010 • SEAP Allocation 178MW (1,500 hrs.) • Owns and Operates 1,210 Miles Of Transmission Lines, 18 Substations and 4 Switching Stations

Who Is Big Rivers (Cont.)? • Three Members (Jackson Purchase Energy Corp., Kenergy Corp. and Meade County RECC) • Member All-Requirements contracts expire January 1, 2023 • Alcan 366MW and Century 484MW: All-Requirements “carve-out” (Big Rivers has no all-requirements service obligation) • Approx. 105,600 Retail Customers • Member Tariff Peak Demand: 664MW on July 29, 1999 (50MW Weyerhaeuser co-generation facility in-service July 1, 2000 (Excludes Alcan and Century)

  5. Linux at Big Rivers • Internet Presence for E-mail Service - Three Domains for Brec and Coops • Internet Proxy access for Brec and Meade - Co. Coop • Website Service for Brec and Meade Co. • DNS Service for Brec and Coops • Firewalls and Masquerade Service • Virtual Private Network Portals • Intrusion Detection Servers • Routers

  6. Big Rivers’ EMS Headquarters’ System • - Six SuSE Linux Servers • - 2 Dac, 2 History, 1 OTS, 1 IDS • - Eight Windows XP Local Clients • - 3 Dispatch, 2 Engineering, • - 2 OTS and One Forecast • - One Windows XP Remote Client • Alternate Control Center System • - Six SuSE Linux Servers • - 2 Dac, 2 History, 1 OTS, 1 IDS • - Three Windows XP Local Clients • - 3 Dispatch Workstations • Hardware is IBM XSeries & NetVista

  7. Big Rivers’ EMS (cont.) • OSI Applications on Both Systems - Scada to 30 Full Sized Remotes - Scada to 40 Pole Top Remotes - Open Trend and Open View Displays - AGC and NERC Functions - ICCP for connections to TVA & LEM - Historical Data Collection & Reports - State Estimation, CA, & Power Flow - Operator Training Simulator

  8. Big Rivers’ EMS (cont.) • Linux Applications on Both Systems - Operating System on Servers - Firewall Service on all Servers - IDS with AIDE and Host SNORT • Windows Applications on Both Systems - Operating System on Work Stations - Word and Excel Document Sharing - Virus Scanning - No Internet or E- Mail Access

  9. Security Concerns • Every Scada a target for power disruption • Open Source verses Proprietary Source - Are bad guys adding back doors to apps - Are good guys watching to protect user - Are you sure code ok in proprietary code • Hackers are no longer using easy entries - Hackers are trying to break applications - Hackers going for opening in clients and tunnel with VPN’s or Secure Shells

  10. Benefits - Linux • Incredible Stability of Server OS • Total Cost of Ownership VERY Low • Incredible Control of Networking • Incredible Security Available • Incredible Speed and Performance

  11. Benefits - Windows • Easy to Use for Dispatchers and Engineers • Easy to Share Data Between Users • Applications Have Similar Interfaces

  12. Open Systems International • Dedication to their Products on Linux • Great Support and Development • Great Enthusiasm for Linux • Strength in Leadership and Vision - First To Offer Their Product on Linux - First To Deploy a Linux Based EMS • Flexible, Simple and Easy to Manage EMS - Simplicity in Design is Very Tough

  13. Primate Technologies, Inc. • Previous EMS a Harris now GE System • 2 Man years in Displays • Dispatchers depend on World Map • - Dispatchers use Substation Tabulars • Primate-Tech created utility to convert - Not easy task moving from Unix to Win - Graphic builders are very complex - Great Job of Conversion !

  14. Final Comments • There is no Perfect Operating System - No Individual or Group can write flawless code - No individual can know everything about the operating system or application - No dispatcher can always make perfect decisions even with the best information a system can provide • The Best Security is Isolation … not always possible!

  15. Your Comments And Questions Thank You for Having Me It has been a Pleasure speaking with you!
