V3 Energy LLC www.v3energy.com Tok, Alaska Wind Power Feasibility Study P a g e | 2 Community of Tok Tok is an unincorporated community east-central interior Alaska, located at the junction of the Alaska Highway and the Tok Cutoff to the Glenn Highway. It is 93 road miles (150 km) from the U.S.-Canadian border and serves as an important refueling and re-supply stop for trans-border travel. All vehicle traffic between the population centers of Alaska and Canada/Continental U.S. passes through Tok. Tok has 1,239 residents, according to a 2016 Alaska Department of Commerce, Community and Economic Development (DCCED) census. It is uncertain how Tok got its name. However, the nearby "Tokai River" was first reported in 1887 by Lt. Allen. "Tok River" was recorded in 1901 by the USGS. Tok began in 1942 as an Alaska Road Commission camp. So much money was spent in the camp's construction and maintenance that it earned the name "Million Dollar Camp" by those working on the highway. In 1944 a branch of the Northern Commercial Company was opened, and in 1946 Tok was established as a Presidential Townsite. With the completion of the Alcan Highway in 1946, a post office and a roadhouse were built. In 1947 the first school was opened, and in 1958 a larger school was built to accommodate the many newcomers. The U.S. Customs Office was in Tok from 1947 and 1971 before it was moved to the border crossing. Between 1954 and 1979, a U.S. Army fuel pipeline operated from Haines to Fairbanks, with a pump station in Tok. The pump station's facilities were purchased as area headquarters for the Bureau of Land Management. The U.S. Coast Guard constructed a LORAN (Long Range Aid to Navigation) station in 1976. Four 700 ft. high towers, located six miles east of Tok junction, transmit radio navigation signals for air and marine traffic in the Gulf of Alaska. In July of 1990, Tok faced destruction when a lightning-caused forest fire jumped two rivers and the Alaska Highway, putting residents and structures in peril. The town was evacuated and the efforts of over a thousand firefighters could not stop the fire. At the last minute, a "miracle wind" (so labeled by Tok's residents) sprang up, diverting the fire just short of the first building. The fire continued to burn the remainder of the summer, eventually consuming more than 100,000 acres of forest. Evidence of the burn can be seen on both sides of the highway east of Tok. The Tok area was traditionally Athabascan Indian, although the current population is primarily non- Native. Tok has become known as the “Sled Dog Capital of Alaska.” Although residents have chosen not to incorporate as a municipality, there are numerous local volunteer committees for various community functions and various membership organizations.1 Two communities are electrically interconnected to Tok: Tanacross and the Native Village of Tetlin. Tanacross, located 12 miles west of Tok, has 108 residents. The Athabascan Native Village of Tetlin, located 20 miles southeast of Tok, has 110 residents. 1 Tok community information from State of Alaska Department of Commerce, Community, and Economic Development, Community and Regional Affairs website: https://www.commerce.alaska.gov/dcra/DCRAExternal/community Tok, Alaska Wind Power Feasibility Study P a g e | 3 Figure 1: USGS topographic map of Tok and vicinity Alaska Power & Telephone Co. Alaska Power and Telephone Company (AP&T) is the electric utility for the community of Tok. It is based in Port Townsend, Washington and serves as the utility for 26 Alaska communities, including Skagway, Haines and all of Prince of Wales Island. AP&T’s renewable portfolio include the operation of seven hydroelectric projects in Alaska. AP&T’s interest in wind power began 2009 by discussions with Alaska Energy Authority (AEA) about wind site options on 7-Mile Ridge, the dominant mountain ridge southwest of Tok. Areawide Wind Resource Areawide mesoscale 2 wind models to evaluate the wind resource in an area of interest are an extremely useful tool for prospecting wind power locations. Several options are available via online access, but the model of choice is the AWS Truepower Windnavigator, which provides 200-meter resolution (more micro-scale in resolution than mesoscale) for most land areas on Earth. Windnavigator is particularly powerful in that, in addition to high resolution imagery, statistical information at multiple height settings are obtainable, including mean wind speed, wind rose, Weibull distribution and monthly variation. Windnavigator is only a model of course and hence not as reliable as field-measured date but use of it greatly aids the selection of most-viable wind power site options and reduces the risk of installing met towers in less desirable or outright poor locations. The evolution of the Tok wind power project was such, however, that the Windnavigator model was only consulted after met towers were installed and operational. Windnavigator does not contradict the met tower locations as reasonable choices, but it does lend insight into the broader view of wind power options in Tok and alternate site options nearer the met towers themselves. 2 An intermediate scale, between the scales of weather systems and microclimates where storms and other phenomena occur; Google Dictionary definition Tanacross Tok Tetlin Village Chisana Mountain (Tok, Alaska) Wind Resource Assessment Report Chisana Mountain met tower, photo by Douglas Vaught February 1, 2018 Douglas Vaught, P.E.

Presumably this transition reflects drier conditions of later winter when all surface water sources are frozen and typically dry, cold air dominates. By spring, temperatures warm sufficiently to deny the possibility of significant icing.
