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

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

AVEC Board 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 1 st, 2010 AVEC reduced rates 2 cents/kWh

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

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

In 2009, kW 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.

#16 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. AVEC and its contractors are building local capacity by training wind technicians who live in the villages.

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

Kivalina Examples of Possible Hydrokinetic Projects

Shaktoolik Examples of Possible Hydrokinetic Projects

Shishmaref Examples of Possible Hydrokinetic Projects

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
