International Airport Rd.Anchorage, AK 99518“10,000 Years of Sustainability… and Counting”
Aleutian Pribilof Islands Association, Inc.LOGISTICS•Anchorage to Nikolski is 916 air miles for $1,316 rt – refundable fare.•During fishing times in Dutch Harbor the price rises to $2,648 rt.•Weather Rules.
•Fuel deliveries get delayed by weather and more recently by fuel company policy.•Diesel retails for up to $5.00/gallon.•Electricity costs $.42/kWh to produce. •To improve Umnak Power’s sustainability Ampy Pre-Pay Electric Meters were installed in March of 2007.Mt. Visavidov and Mt. Rechesnoi, both active volcanoes, dominate the scene on a clear day.The unofficial population of Nikolski is 34.Photo by Tyler Schlung

Nikolski Wind Resource ReportSummary Information Nikolski has superb potential for wind power development with Class 7 wind power density, moderate wind shear, bi-directional winds and low turbulence. Meteorological Tower Data SynopsisWind power class(measured to date) Class 7 – SuperbAverage wind speed(30 meters) 9.01 m/s(at 30 meters) Maximum wind gust(2 sec average) 40.9m/s, 1/24/07, 12 p.m. Turbulence Intensity(30 meters) 0.108 Data start date December 11, 2005 Most recent data date March 13, 2007
Nikolski Project Facts•Umnak Power is owned by the Nikolski IRA.•Average electric load is 25 kW.•Peak load is 50 kW.•AEA “commissioned” a new diesel plant with 2 John Deere 70 kW generators and one 37 kW generator in May of 2006.•USDA/RUS awarded APIA $474,475 to incorporate a remanufactured Vestas V-15 (65 kW) wind turbine with the diesel plant. •The rising prices for steel, concrete and freight has increased the budget by nearly $100,000 since grant award.•Unfunded modifications to the controls in the diesel plant may be required. Cost yet to be determined.
•A tilt up tower was designed and built by TDX Power and Halus in San Francisco, CA.•The tower was shipped in pieces and assembled on site.•The tower is 80’ high and weighs 7,000 lbs.•At $60,000 this tower design saved the project the cost of leasing and transporting a crane to the site.
The gin pole is a rectangular metal frame.
Three winches, fitted with strain gauges, are operated by a master hydraulic control unit.
The tower must come down within ¼ inch of the bolts set in concrete.
•The turbine was erected over 12 hrs. on July 28, 2007.•Connection is pending repairs to the diesel power plant and an assessment of the existing controls.•Penetration level is pending evaluation of new technology –Static versus Dynamic mean VAR support.
Aleutian Pribilof Islands Association, Inc.Lessons Learned•Build a significant contingency fund into your budget. •A power plant operator that loves the job and does it well is priceless.•Technical problems are usually much easier to solve than people problems.
