Here you will find information about the 2002 Wind-Diesel Workshop held September 23-25, 2002 in Anchorage, Alaska.
The Wind-Diesel 2002 Workshop presented the latest operating experience, design concepts, system components, related R&D, comparative economics, and institutional delivery strategies from around the world. Following the workshop, participants had the opportunity to visit two Alaska wind-diesel systems in Kotzebue and Wales, which provided in-depth review of these pioneering projects.

Field Tours to Kotzebue and Wales, Alaska
Kotzebue Electric Association (KEA) is a non-profit cooperative, which owns and operates an 11.2-MW capacity diesel electrical utility to provide power for Kotzebue, Alaska. Kotzebue is a community of 3,500 people and is the service hub for all villages in this northwest region of Alaska. KEA has a staff of 15 people, including power plant operators, diesel mechanics, electricians, trained lineman and administrative staff. The village has a peak electrical load of approximately
3,900 kW, with an average of 2,800-kW load. In addition to operating the local utility,
KEA has agreements with other communities in the region to provide utility operations and maintenance assistance.
The KEA wind power project consists of 11 wind turbines installed at a single site totaling 0.76 MW of rated capacity. Ten of the turbines are AOC 15/50 models, manufactured by Atlantic Orient Company of Norwich, Vermont. Three of the turbines have been operating since July 1997 and the others were installed in 1999. The AOC 15/50 is a three-bladed, downwind turbine with at 15-meter rotor diameter.
The eleventh turbine, a
North Wind 100, is manufactured by Northern Power Systems of Waitsfield, Vermont. It was installed in April 2002. The NW 100 is a three-bladed, upwind turbine with a direct-drive generator designed for cold climate conditions, remote villages, and distributed generation.
Two more AOC 15/50's are scheduled for installation in March 2003.
Wales, Alaska is a remote Inupiat Eskimo village of approximately 160 people located on the western tip of the Seward Peninsula, just across the Bering Strait from Siberia. Access in and out of Wales is normally provided by small air
service companies based out of Nome, 111 miles to the southeast. The town has a school, small store, post office, washeteria (containing washing machines, showers, and toilets), and health clinic. Running water is available in these buildings as well as a select few others.
A small, diesel-electric generating plant has supplied electricity to the village for years. However,
in 2000, the diesel plant was retrofitted with wind turbines, energy storage, and a sophisticated control system. It is predicted that this high-penetration wind-diesel power system will reduce diesel fuel use by 50% or more.
Wednesday, September 25, a group of 18 people from the Wind-Diesel Workshop toured the Wales high-penetration wind-diesel power system. The group included people from Argentina, Australia, the
Philippines, Spain, Canada, Colorado, Texas, Vermont, and Alaska and represented industry, government agencies, and utilities. Participants arrived in Wales at 9:30 a.m. after traveling on a chartered plane from the Wind-Diesel Workshop in Anchorage. The group was greeted by Ellen Richard and
Winton Weyakpuk, the mayor and vice-mayor of Wales. Ellen accompanied the tour for the entire duration. The weather was cool and cloudy but dry. Unfortunately, it was also quite calm and neither of the wind turbines were spinning.
The diesel powerhouse is located at the north end of town, approximately 1/2 mile from the airstrip. The group stopped here first to check out the diesel plant, existing diesel controls, and master wind-diesel control panel.
Next, the group visited the energy storage subsystem, located directly behind the diesel powerhouse. This container houses the battery bank, rotary converter, and rotary converter control panel. From there, the group walked the length of town to the school where they were greeted by the Principal Don Yates. With his permission, the group checked out the electric dump load and associated control panel installed in a storage room in the school. Finally, the group walked back towards the airstrip and stopped to check out the wind turbines and wind turbine control shelter housing the wind turbine control panels and associated equipment. The plane departed at noon.
