Naknek – Cape Suwarof

Cape Suwarof, Naknek, Alaska

The wind resource at proposed Cape Suwarof wind power site in Naknek shows very good potential for wind energy development as a high Class 4 (near Class 5) wind power class resource with excellent turbulence behavior. Note that the measured wind power class is higher than predicted by the Alaska Wind Resource Map (see below) which forecast a Class 3 resource at the test site.

Manokotak

The wind resource at the proposed wind power site in Manokotak shows fair potential for wind energy development as a mid-Class 2 wind power resource with good turbulence behavior. This is a bit lower than expected and it had been thought that the site, chosen with considerable care as the most promising developable wind power site in Manokotak, might yield a better wind resource. Viability for wind power development, though, depends on the price of electricity, so given the high cost of diesel fuel and hence electrical power in Manokotak and despite the lower than desired wind resource, a wind power project may still make good sense for the community. An economic analysis of this question, however, was not within the scope of this study.

Togiak

Togiak, Alaska

Togiak’s winds are possibly lighter than expected given its geographic location on the Bering Sea coast. This may be due to the met tower site location well down on the northeast side of the hill that comprises the Togiak Heights subdivision. Possibly more exposed locations in Togiak would experience higher wind speeds, but it should be noted that Class 3 winds in this area are predicted by the Alaska Wind Resource Map.

Dillingham – Kanakanak

Kanakanak Dillingham Site

Winds measured in Dillingham were consistent with the State wind resource map and are sufficient for wind power development in the community. Because of the proximity of forest to the wind test site, the wind shear and turbulence were higher than seen in other Bristol Bay region communities. Because a successful wind power project has the potential to lower the electrical power generation costs in Dillingham, installation of a 50 meter meteorological tower and selection of a site further from the forest margin may yield better data.

Perryville

Perryville, Alaska

The wind resource study in Perryville defied expectations of measuring strong winds. It appears that local geographic features effectively shield the test site, and the nearby village, from the ferocious winds common to the southern Alaska Peninsula coast. With a measured wind power class of 2 (marginal), Perryville does not appear at this time to be a promising location for village-scale wind power development, although there is always the possibility of successful home-scale wind power development.

New Stuyahok

New Stuyahok, Alaska

New Stuyahok has fair to good potential for wind power development, provided a slightly better location for wind turbines is found than the meteorological tower test site. The test site appeared to be adversely affected by the presence of trees nearby. When the new airfield opens and the old one abandoned, the old runway would be an ideal location for wind turbines: it is higher and more open than the met tower test site, and turbine foundations would be easier to construct.

Naknek – Landfill Area

Naknek Alaska

The measured wind resource in Naknek showed good potential for wind energy development as a mid-Class 3 wind power class and excellent turbulence behavior. The monitored site, near the borough landfill, does exhibit more wind shear than desirable, necessitating tall turbine towers, and in other respects may not be desirable to develop, but there is plenty of similar terrain nearby suitable for wind power development. In July 2006, the meteorological test tower was moved to a site closer to Naknek Bay which may prove superior to the landfill site because of its closer proximity to onshore winds; early data recovery from the new site suggests this will be the case.

Koliganek

Koliganek

The wind resource study in Koliganek indicates very good potential for the development of wind power to augment the village’s diesel power supply. One excellent advantage for the village is the old airstrip where the meteorological test tower was located. Because the village and surrounding area is comprised of permafrost soils, construction of wind turbines on the old airstrip would significantly reduce construction costs.

Kokhanok

Kokhanok, Alaska

The wind resource in Kokhanok is superb by any measure – the winds are steady, smooth, low shear, highly directional and high power class. The selected wind site, near the tip of the spit of land jutting into Lake Iliamna (see photo above) is ideal for wind turbine installations as it is relatively far from the village but near an existing overhead power line, is comprised of stable rocky soil, and is in a location unlikely to be desired for other village uses (because of the wind).

Dillingham – Woodriver Road

Winds measured in Dillingham were consistent with the State wind resource map and are accept-able for wind power development in the community. Because of the structural mass and complexity of the State EMS tower used as the test platform, the wind shear and turbulence were higher than is likely true. Because a successful wind power project has the potential to lower the electrical power generation costs in Dillingham, installation of a 40 or 50 meter meteorological tower nearby may yield better data.
