  1. National Rural Electric Cooperative Association (NRECA) Electric Cooperatives Over 900 co-ops 42 million in 47 states 75 percent of land area 83 percent of counties fully or partially served 42 percent of nation’s distribution lines 7 customers/line mile 50% Suburban and 25% micro urban Largest aggregation of coal power plants

  2. G&T Cooperative Service Area - 2006 Associated Basin San Miguel Southern Montana

  3. G&T CooperativesThe Largest Domestic Coal Based System

  4. 27 Co-op Coal Projects MW New Capacity of 9,360 MW over 10 years Project Status (# plants; MW) On-line (1; 200 MW) Under Construction (6; 830 MW) Planned (15; 5,879 MW) Exploratory (5; 2,450 MW) KEPCO Iatan E TX Plum Point Year Expected On-Line

  5. Co-op Principal Mission Keeping electricity reliable and the rates affordable

  6. Co-op Business Realities Innovation—a result of unique circumstances Small utilities with limited staffs Sparse service territories Not for profit Consumer-owned & consumer-governed Overwhelmingly residential and farms Profound impact of 1978 Federal Fuel Use Act Household incomes below national average Federally set construction standards, technical specifications, augmented by industry best practices

  7. NRECA Cooperative Research Network (CRN) Demonstration Projects Goal of NRECA CRN “reliable electric serviceat an affordable cost”

  8. Co-ops and Smart Grid Investment Grants More than 50 Electric Cooperatives and Public Power Districts in 16 States Awarded Over $215M AR, AZ, FL, GA, KS, KY, MS, NE, NH, OR, PA, SD,TX, VA, VT,WY

  9. CRN-Coordinated NRECA/DOESmart Grid Demonstration Grant 22 co-ops in 10 states—$68M project Selected by DOE for $34M grant Install and study range of technologies Project team includes: SAIC, Cigital Power Systems Engineering, ICF Pacific Northwest National Laboratory EPRI and Industry

  10. NRECA Energy Storage Demo ProjectWhy the choice of the Premium Power Corporation Zinc Bromide Battery? • Lifetime of more than 10,000 cycles of deep charge and discharge • Lowest cost battery of all the advanced options based on CRN due diligence report • Potentially very low environmental impacts • PPC ZnBr is UL, FCC, and NFPA certified • PPC has recently completed the production of its first TransFlow 2050-5 (500 kW, 2.8 MWh, 5.6 hours) • PPC has production capacity to meet the needs of the participating co-ops in this proposal. • The PPC ZnBr batteries are made in the U.S. • PPC is well capitalized. • PPC ZnBr has the potential for fast frequency regulation and nearly unlimited cycle life.

  11. ZnBr Battery AttributesPremium Power Corporation & ZBB

  12. Premium Power Corporation TransFlow 2050-7Zinc Bromide battery on a trailer 500 kW, 7.4 hours and 3.8 MW-Hr & $1.055 million

  13. NRECA Energy Storage Demo ProjectPlanned Installation Sequence • First-Kotzebue Electric Association, Alaska 0.5 MW / 7.4 hours/3.7 MWh to time shift wind and provide frequency regulation • Second-Kauai Island Utility Cooperative, Kauai PMRF, 1.0 MW /7.4 hours/7.4 MWh to time shift solar, provide frequency regulation, and for backup power to PMRF during islanding • Possibly-Seminole Electric Cooperative, Inc., Florida1.0 MW / 5.6 hours/5.6 MWh to time shift solar.

  14. Biomass Co-Firing with Coal Technical and Economic aspects of Biomass Cofiring and Supply with an Assessment of All G&T fossil plants

  15. Identification with Alliance with INL the Utilization of CO2 from Fossil by Conversion to Syngas, Liquid Fuels, and/or Chemical with High Temperature Co-Electrolysis High Temperature Co- Electrolysis (HTCE) Generates “Green” H2, O2, CO Efficient Operations @ Temperatures > 600 °C Power to Operate from Nuclear/Renewable Energy Sources HTCE Minimizes Carbon Emissions: Manages carbon emissions through conversion to liquid fuels Starting point for commercial synthetic chemical products • Operation: • HT Steam & CO2 • Recycled CO2 from combustion process • O2 produced at Electrode 1 (with use for IGCC or OxyCombustion) • H2 & CO (Syngas) produced at Electrode 2 for conversion to liquid fuel and/or chemicals

  16. Completed Short-Term Solutions to Transmission Congestion Priority of Fixing Transmission Congestion: • Implement transmission optimization software in operational planning • Examine and implement dynamic rating of lines • Improve EMS (or install EMS if not in place) • Install Advanced Conductors and upgrade transformers • Install distributed dynamic flow control devices • Install FACTS devices

  17. Impact Comparison of OH vs UG Lines • Visibility • Environmental • Wetlands, water, threatened and endangered species habitat, cultural resources • Land use • Agriculture, airports, roads • EMF

  18. Economic Analysis of Overhead and Underground Transmission Lines Using the Tangible and Intangible Cost Components • Used to support decisions to build overhead (OH) transmission lines versus underground (UG) transmissions lines • Detailed manual of design, construction, and operation of OH versus UG lines • Spreadsheet with detailed economic evaluation of overhead and underground transmission lines including tangible and intangible cost components

  19. CRN Project to Evaluate Real Time Reliability (Optimization) Software with HOST EKPC • Improves reliability and increases available transfer capacity (by 2 X or 3 X) by applying a minimum number of mitigation measures based on a user-defined priority schedule which may include: • MW Dispatch • MVAr Dispatch • Capacitor and Reactor Switching • Transformer Tap Change • Line Switching (In and Out) • Optimal Capacitor, Reactor, or FACTS Placement and size • Phase Shifter settings • Load Curtailment • Defined Operating Procedures • Switching Not Affected Lines After Optimization Before Optimization

  20. Using Optimization Software with 3D GUI to Increase the Size of the Operating Region in an Operating Environment at EKPC results after using Optimizationn (ATC increased from 1400 MW to 3400 MW) results prior to using Optimization

  21. CRN Project to Evaluate Voltage Stabilizing Technologies at Tri-State and Basin Electric FACTS device (AEP UPFC) • Provided Evaluation of Existing Options for Voltage mitigation and Stabilization (Capacitors, SVCs, FACTs devices) • Provide Evaluation of Future Options for Voltage Stabilization (SuperVAR, CNT, TACC, etc.) • Used Ultra Fast Transmission System Optimization Software To Determine the Optimum Option for Voltage Stabilization for long distance transport of power to TriState G&T SuperVAR-High Temperature Super Conducting Synchronous Condenser

  22. Completing and Commercializing “Smart Wires” Power Flow Control Device Zenergy Power is Commercializing a “Smart Wire” Distributed Series Reactor (DSR) licensed by GATECH NEETRAC to be clamped onto a transmission line to accomplish: • Defer building of new lines • Massive redundancy • Zero footprint solution • Mass produced modules • Easy and rapid installation • Control power flow along contract path • Maintenance with existing workforce • Reduced time to deploy and overall cost
