Wind: A Mature Technology
  • Technology has matured over the past 25 years
  • Operating availabilities of    98-99% with large turbines
  • Performance and cost have dramatically improved
  • New hardware is being developed on multiple fronts:
    • higher productivity and lower costs
    • tailored designs for lower wind speeds and extreme weather conditions

Wind Turbine Sizes and Applications
32
Alaska Wind Projects
  • Wales (AVEC)
  • Kotzebue (KEA)
  • Selawik (AVEC)
  • St. Paul Island (TDX Power)
  • Toksook Bay (AVEC)
  • Kasigluk (AVEC, under construction)

Kotzebue Electric Association
Low Penetration Wind-Diesel System
Kotzebue, Alaska
  • 3 EW15 (65 KW) turbines installed in 1997
  • 7 more EW15 turbines installed in 1999
  • 1 North Wind 100 (100 KW) installed in 2002
  • Planned installation of 2 V17s and 3 EW15s in 2006

Wind Penetration consideration
  • Low penetration: wind provides < ~30% electrical load (minimal controls required)
  • Medium penetration: 30% < wind < 60% (controls needed to handle power dynamics of turbines)
  • High penetration: wind > 60% (possibility of 100+% power from wind, need dump loads, etc., may also want low load diesel to handle diesel-off conditions
55
How does Dillingham compare to other Alaska hub communities?
  • Kotzebue started their wind farm several years ago, but…
  • Dillingham is in similar position as Bethel, Nome, Naknek and Kodiak – you have the wind resource but must decide if you wish to move ahead
  • AEA would like to sponsor a group purchase of turbines for hub communities – contact Reuben Loewen of AEA, 269-3027
56
Project Needs and Considerations
  • Geotechnical analysis of site
  • Turbine foundation design/construction
  • Turbine erection (crane required)
  • Transmission lines to site
  • Transformer(s)
  • Basic turbine controls, fuses, etc.

AEA Request for Grant Proposals
  • #AEA-06-018, Construction of Wind Energy Projects
  • Issued Feb. 13, proposals due Mar. 13
  • Purpose is to provide funding assistance to utilities for projects that expand utility-scale wind power in rural Alaska
  • Eligibility: certified electrical utilities and independent power producers
  • Funding: $1.47M with possibility of more in 6/06
  • Contact AEA, Reuben Loewen, 269-3027 or Peter Crimp, 269-4631
