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 nations distribution lines 7 customers/line mile 50% Suburban and 25% micro urban Largest aggregation of coal power plants
G&T Cooperative Service Area - 2006 Associated Basin San Miguel Southern Montana
G&T Cooperatives The Largest Domestic Coal Based System
27 Co-op Coal Projects 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 Project Status (# plants; MW) New Capacity of 9,360 MW over 10 years Year Expected On-Line
Co-op Principal Mission Keeping electricity reliable and the rates affordable
Co-op Business Realities Innovationa 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
NRECA Cooperative Research Network (CRN) Demonstration Projects Goal of NRECA CRN reliable electric service at an affordable cost
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
CRN-Coordinated NRECA/DOE Smart 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
NRECA Energy Storage Demo Project Why 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.
ZnBr Battery Attributes Premium Power Corporation & ZBB AttributeRating 1.Capital costExcellent - $250/kW-hr 3. Round trip efficiencyFair–70% to 75% 4. Lifetime in Cycle LifeExcellent (>>10,000 cycles) 5. MaintenanceGood-pumps Has an on-line monitoring system 6. Minimal EH&S issuesExcellent 2. Volumetric Energy Density (Wh/l) Excellent (250 to 350) 7. Energy density (Wh/kg) Fair (75 to 85) 8. RiskGood TF-2050 is being built and shipped
