TDX Power in Alaska: Saint Paul Island TDX Power in Alaska: Saint Paul Island _______________________ •System:500 kW standalone utility: combined heat and power •Configuration: High penetration/no storage wind-diesel •Application: Public power supply, providing electricity and space heat to industrial/airport facility •Avg. Power Generation: 700,000 kWh per year –36% capacity factor •Funding:Private commercial, lease based •Cost of Energy: $.12/kWh (current diesel grid cost is $.49/kWh) •Wind turbine gearbox failures caused by design flaw –downtime during peak winter wind resource –failure resolved by manufacturer redesign resulting in dramatic increase in wind kWh production •Overall system performance and benefits strong over five years. 100% availability on 2004 and 2005. Capacity factor over 60% in January 2006. Saint Paul Island: Performance Summary •In 2004, TDX committed to expanding the plant to provide additional low cost energy on island. •Four used V27's purchased from Denmark - remanufactured in California. •Remanufacturing process includes complete disassembly. inspection and remanufacturing of turbine parts. Also includes generator rewinding, blade resurfacing, and new wiring and cables. Saint Paul Island Plant Expansion Average Power Costs in the Aleutians: (2005 PCE Stats.) •Cold Bay 49.93 cents/kwh •False Pass 48 cents/kwh •King Cove 38 cents/kwh •Nelson Lagoon 42 cents/kwh •St. Paul 46 cents/kwh •Sand Point 39 cents/kwh •Unalaska 30 cents/kwh Windpower in Sand Point Vestas V39 Turbine: •500 Kw wind turbine •40 meter tower •39 meter rotor (swept area) •Manufactured in 1991 •Remanufactured by Halus Power Systems 2006 Windpower in Sand Point Vestas V39 Turbine: •500 Kw wind turbine •40 meter tower •39 meter rotor (swept area) •Manufactured in 1991 •Remanufactured by Halus Power Systems 2006 Windpower in Sand Point Proposed System Overview: •Two (2) Vetas V-39 turbines •One (1) Low Load, High Efficiency Diesel engine generator set - Caterpillar D-3456 •One (1) Synchronous Condenser •Thermal or Electric Heat recovery System •Projected Cost: $2.46 million Windpower in Sand Point Proposed Structure: •Public-Private partnership with AEA •Project will be a Qualifying Facility (QF) under PURPA certified by FERC •Anticipated rate will be less than 50% of existing utility avoided fuel cost Windpower in Sand Point Project Benefits: •Utility diesel fuel consumption reduced by 126,429 gallons. Current cost of fuel $3.06/gallon. Total fuel savings $386,872 •Further diesel heating fuel savings at clinic, school and community building •Promotes economic development •All risk of the project resides outside of the utility •Statewide PCE program and other communities will benefit from decreased fuel use in Sand Point Windpower in Sand Point _______________________ USAF Tin City Long Range Radar Site (LRRS) Remote Wind Diesel Project In NW Alaska Tin City •$2 million project –funding delayed and now rescheduled for summer of 2008. •Major issue to address will be rime ice on Vestas V27 turbine NIkolski •RUS funded project to add wind power to the new diesel plant. •TDX Power hired by APIA to install a Vestas V17 wind turbine.
