  1. Wind Working Group Nome, AK November 2010 Alaska Village Electric Cooperative Toksook Bay, Alaska Brent Petrie Anna Sattler

  2. AVEC is a non-profit member-owned co-op • 53 villages • 22,000 population • Would be the 4th largest city in Alaska after Anchorage, Fairbanks and Juneau • 94% Alaska Native • 48 power plants • 9 wind systems serving 12 villages • 160+ diesel generators • 500+ fuel tanks • 5 million gallons fuel burned • 7,700 services • 80 Anchorage-based employees • 95 Village technicians

  3. AVECBoard Goals • Reduce diesel use by 25% in 10 Years • 1,250,000 gallons • 77% of our fuel is used in Wind Class 4+ villages • Reduce power plants by 50% in 10 Years • Interconnect another 24 villages • Reduce non-fuel costs by 10% • Plant costs, depreciation, interest… • On January 1st, 2010 AVEC reduced rates 2 cents/kWh

  4. Wind Potential for AVEC • 39 of AVEC’s 53 villages are in 4+ wind regimes • A high-efficiency generator yields 14 kWh/gallon • A 100-kW turbine could produce 220,000 kWh/yr • One unit could displace 16,000 gallons • Four units = 64,000 gallons

  5. Wind Map

  6. AVEC Wind Projects • 2003 Selawik • 2006 Kasigluk – with tie line to Nunapitchuk • 2006 Toksook Bay - with tie line to • Tununak & tie line to Nightmute • 2008 Hooper Bay and Savoonga • 2009 Gambell and Chevak in construction, commissioning in process in 2010 • 2009 Mekoryuk erected, commissioning in 2010 • 2010 Quinhagak– erected, commissioning in 2010 • 2010 Toksook(one more turbine) • 2011 Emmonak/Alakanuk and Shaktoolik Kasigluk

  7. Future Interties • BrevigMission - Teller • St. Mary’s - Mt. Village • St. Mary’s - Pilot Station • St. Michael’s - Stebbins • Emmonak - Alakanuk • New Stuyahok - Ekwok • Togiak - Twin Hills • Noorvik – Kiana – Selawik • Ambler – Shungnak – Kobuk • Upper Kobuk – Lower Kobuk

  8. Wind Potential for AVEC We would need 80 100kW machines to displace 1,250,000 gallons. • As of November 1st, 2010, we have 19 100kW units operational and 5 more scheduled to be operational in the next 2 months. • Construction is scheduled to begin on 6 100kW machines in 2011. • 4 65kW machines were installed in Selawik in 2003.

  9. In 2009, 11 100kW machines were operational for the entire year and, including limited output from the 4 smaller turbines at Selawik, wind accounted for 2.8% of gross generation, displacing about 140,964 gallons of fuel. The fuel would have been worth $517,931.

  10. AVEC 2009 Fuel Use By Village

  11. Using wind fuel, AVEC has saved a total of:

  12. Fuel Oil Savings Per Year

  13. Fuel Oil Displaced in Gallons Per Year

  14. Building Human Capacity AVEC and its contractors are building local capacity by training wind technicians who live in the villages. These trainees have worked in the construction and operation of the new systems. Charles Green Sr. of Toksook Bay - leftElias Friday of Chevak - middleLawrence Lake of Hooper Bay - right #16

  15. Training is underway for several wind technicians Kasigluk, March 2010

  17. Selawik, AlaskaNew modular power plant, bulk fuel tank farm, four wind turbines, and waste heat recovery system

  18. Other Projects Port Clarence Hydrokinetic Project • Hydrokinetic power generation in Port Clarence at the entrance to Grantley Harbor near Teller and Brevig Mission

  19. Port Clarence Hydrokinetic Project Project Area

  20. Port Clarence Hydrokinetic Project

  21. Port Clarence Hydrokinetic Project Port Clarence Teller Brevig Mission Area of high velocity tidal currents Grantley Harbor

  22. Port Clarence Hydrokinetic Project Replicability elsewhere in Alaska • The outcomes of this study can be applied to similar locations along Alaska’s northwest coast, where barrier islands and narrow ocean spits dominate the landscape

  23. Examples of Possible Hydrokinetic Projects Kivalina

  24. Examples of Possible Hydrokinetic Projects Shaktoolik

  25. Examples of Possible Hydrokinetic Projects Shishmaref

  26. Port Clarence Hydrokinetic Project Project benefits • Reduced energy costs in both communities • Lessons learned (study methods, feasibility analysis and generator selection methodology) which could be applied to other communities
