The report is also based on a site visit conducted in May 2010, and information from vendors, experience with similar projects, and published information on developing community-size wind power projects. Construction of a wind power facility at Port Heiden presents many challenges due to its remoteness from a major urban center. The village is located on the Alaska Peninsula approximately 425 miles southwest of Anchorage and is accessible only by boat or by air. The local runway is a 5,000-foot gravel airstrip and can accommodate several aircraft sizes up to Boeing 737. Water access is via the Bering Sea, but no dock is present. The soil at Port Heiden is mostly composed of glacial till; preliminary historical well drilling results indicate the need for a deep foundation. These factors will result in a relatively high wind power cost-per-installed-kilowatt (kW), due to the high costs of mobilization, transport of equipment and materials, and construction of transmission lines in remote areas. No major environmental or permitting obstacle is expected at this time. However, several state and federal agencies will need to be involved from the inception of the project. The current average electrical load for the village is about 75 kW, and significant growth in demand is not anticipated in the near future. In addition, there is no readily available market for any excess power that may be produced. Therefore, the concept for this study was to minimize costs by designing a facility that generally meets the current needs of the village, while at the same time utilizing excess wind power for space heating purposes and hot water. The wind resource assessment for the local geographical area was primarily based on the measured data at an existing 100 foot (ft) tower supporting a Bergey, 10 kW Excel wind turbine. The data underwent a rigorous quality assurance process to compensate for the lattice-tower shadowing effects on the anemometers and wind vanes. A site survey was carried out in the spring of 2010 to gather data on the electric and thermal loads of the village, the current diesel expenses, and the suitability of a new wind power installation. The site survey also identified potential sites for a wind turbine in the proximity of “Ray’s Place” (community building) and the current power house (see Figure 5). Ray’s Place would benefit from excess wind power through space-heating, while the proximity to the power house would favor interconnection and control aspects of the project. In order to verify the suitability of the identified sites and to calculate values of capacity factor (CF) and annual energy production (AEP) for various turbine models, a refined wind flow model was produced based on: measured wind data, correlations to long-term AWOS station data at the local airport, high- definition (1 m) digital elevation models, and surface roughness. Four turbine models (in their cold-weather package configurations) were considered: Northwind 100B/21 rated at 100 kW; Vestas V27 (marketed as A27) rated at 225 kW; Vergnet GEV-MP-C rated at 275 kW; and Enercon E33 rated at 330 kW. Port Heiden Wind Power Feasibility Study, Rev 0 2 The four turbines differ in size and control systems. The Northwind and Enercon turbines do not have a gearbox, which simplifies maintenance. The Northwind 100 is the only turbine in the group which does not have pitch control. Pitch control assures an optimal energy capture at various wind speeds, regulates the RPMs at the highest wind speeds, and protects the machine by feathering the blades in potentially damaging strong wind events. At the same time, the moving parts are more numerous and the possibility of failures increases. The Vergnet turbine is mounted on a guyed tubular tower that can be lowered for maintenance and in case of forecasted strong wind storms. All the other models come with standard monopole towers, which let the operator climb inside a weather-protected environment. The Northwind 100 could also be mounted on a new lattice system (Parafold), which allows the turbine to be lowered with a winch, does not require heavy cranes for the installation, and allows for simplified foundations. The Parafold system, however, is still in its infancy and should be re-evaluated at the time of project implementation. The calculated AEPs, assuming a 10 percent loss (due to turbine availability, electrical losses, soiling, etc.), range between 300 and 1000 MWh/yr depending on the turbine model assumed, indicating a wind penetration level from mid to high. Lower penetration levels are not economically viable at Port Heiden. The various sites showed relatively small variations in AEP for any given turbine model, thus allowing for some flexibility in the final site selection. Each turbine could potentially be mounted at various hub- heights, trying to optimize the larger AEP against the higher tower and foundation costs. It is shown in this report that a minimum hub-height of 37 meters (m) (121 ft) is recommended. An economic analysis using the HOMER© Micropower Optimization Model (U.S. Department of Energy, 2005 [1]) was conducted for the four turbine models and at various hub-heights, for the site that showed the best wind resource among those identified during the site survey. The HOMER© model output includes several economic measures, including present worth, that show the value of the difference between the wind power alternative and the current diesel-only system. Present worth shows how much the alternative system saves over the project lifetime compared to the diesel-only system, and is the primary measure for comparing the economic feasibility of the two systems (see Section 5.6 for more information). Each alternative was compared to the current diesel system using four assumed prices for diesel fuel: the current price of US$5.15 per gallon (2009 sales data from City of Port Heiden), a price of US$4.62 per gallon, a price of US$5.5 per gallon (identified as the long-term diesel price by Information Insights, 2008 [2]), and a price of US$6.25 per gallon (approximately 20 percent increase with respect to current prices). This approach gives an idea of how the economics of each alternative compares to the current system assuming different prices for diesel, which is the major determinant of the cost of energy produced by the current system. While a due-diligence of the machines needs to be carried out before arriving at the final solution and selection of the most suitable model, the economic analysis has revealed the following main results summarized in Table 10 and Table 18 (repeated here for convenience) for the long-term diesel price as per [2]. The color coding associated with the benefit/cost ratio identifies with green the ‘best economic alternative’, cyan ‘second best’, orange the marginal, and red the unfeasible alternative. The Enercon E33 is the most economically efficient turbine model regardless of the selected hub-height. At 37 m hub-height, the Vergnet GEV-MP-C and Vestas A27 are valid alternatives, followed by a pair of Northwind 100B/21s. The lowest levelized cost-of-unit-energy (COE) is obtained with an Enercon E33 at 50 m hub-height, resulting in a projected reduction in COE of about $0.13/kWh within the assumed long-term oil price scenario. Port Heiden Wind Power Feasibility Study, Rev 0 3 Enercon has a very solid reputation in the international market and has successfully installed turbines throughout the world and in harsh environments in Canada and Antarctica for wind-diesel applications. A patent-dispute prevented Enercon from exporting to the US till 2010. Table 10. Comparison of various alternatives at 37 m hub-heights to current system if diesel price is US$5.5/gal.

The Vestas A27 has shown a relatively good track-record, and may be preferable to the Vergnet for the sheltered conditions inside the tower and nacelle. Furthermore, the Vestas A27 would also fit on a shorter (30 m, approximately 100 ft) tower, and with that hub-height shows benefit/cost ratios of 1.1, 1.07, and 1.05 with a diesel price of $6.25/gal, $5.5/gal, and $5.15/gal, respectively. The Northwind 100B/21 has shown an impressive reliability, though it has only been in the market and operational for less than a decade. This model is considerably more expensive (50 percent) than the others on a per-installed-kW basis, and only at 37 m hub-height and diesel prices at or above $5.5/gal is economically promising. The analysis does not account for emergency maintenance following major unexpected events, but that could be a factor for machines having spare parts difficult to retrieve. For this reason, it is recommended that an inventory of spare parts be acquired at the time of project installation. Because of the harsh wind regime, it can also be expected that a 50-year wind gust may be encountered during the lifetime of the project, and discussion with the turbine manufacturer is encouraged to verify which components may fail under those circumstances. Port Heiden Wind Power Feasibility Study, Rev 0 4 Recommendations for future activities include:  Investigate whether suitable financing is available to develop a wind power installation at Port Heiden given the illustrated initial capital costs and economic benefits.  Initiate permitting process, starting with FAA determination of no-hazard to air navigation, while also initiating discussions with state and federal agencies to identify potential environmental and permitting issues.  Contact Enercon to assess exporting capabilities to the US in 2011.  Identify potential parallel projects that could share the costs for heavy construction equipment, transportation of materials etc.  Conduct geotechnical investigations at the turbine installation site(s).  Identify and recruit local potential workers for construction activities, with the double benefit of reducing expenses and involving the local community in the project.  Identify suitable contractors and engineering/construction management firms.

Introduction 1.1 Background Knight Piésold and Co. (Knight Piésold) was contracted by Lake and Peninsula Borough (LPB) to carry out a feasibility study for the community of Port Heiden in the Southwest Alaskan Peninsula to verify the economic viability of a wind-diesel electric generation facility. The hybrid facility could provide lower cost of energy to the local community, which currently relies on diesel generators to provide electricity. Previous studies conducted in the area (Information Insights, 2008 [1]) estimate that the cost of electricity generated by a small wind power facility could be up to US $0.03/kWh below the projected cost of electricity from diesel generators with heat recovery. This report highlights the main aspects involved in the study at Port Heiden, and the results of the economic analysis for four different types of wind turbines. This project (103-240/4) is part of a widespread wind regional assessment being carried out at various communities within the LPB boundaries. 1.2 Scope of Work The scope of work included a preliminary and a detailed wind resource assessment (WRA), site survey to identify suitability of wind turbine installations, and collection of data for input to an economic analysis, namely: village electrical and thermal load data, village fuel expenses, vendors’ and contractors’ information and quotations. Also included in the scope of work is a review of the permitting requirements. Following a site visit and an initial screening process, four sites were selected for a more detailed analysis, including a conceptual project layout, an estimate of power generation, a preliminary cost estimate, and an analysis of the economic feasibility. 1.3 Sources of Information Information used during the study included GPS data obtained during the site visit; information on wind data, power and fuel consumption from: the power plant maintenance personnel; the Lake and Peninsula Borough; the Lake and Peninsula School District; and the City of Port Heiden; information on the design of the existing power plant from the City of Port Heiden; information on the physical setting collected by Knight Piésold staff during a site visit; geologic maps and reports, and topographic maps from the United States Geological Survey (USGS), MODIS (or Moderate Resolution Imaging Spectroradiometer), the State of Alaska, and the Lake and Peninsula Borough. 1.4 Limitations and Disclaimer This report titled Port Heiden Wind Power Feasibility Study has been prepared by Knight Piésold for the exclusive use of LPB.

Port Heiden is 424 miles southwest of Anchorage, at the mouth of the Meshik River, on the north side of the Alaska Peninsula. It lies near the Aniakchak National Preserve and Monument. The community lies at approximately 56.948390° North Latitude and -158.629020° West Longitude, and at an average elevation of 70-100 ft (20-30 m) above mean sea level (MSL) (Sec. 27, T037S, R059W, Seward Meridian.). The village is accessible only by air or water. The local runway is a 5,000-foot gravel airstrip and can accommodate several aircraft sizes up to Boeing 737. Water access is via the Bering Sea, but no dock is present. 2.2 Climate The climate of Port Heiden is typical of the Alaska Peninsula, with cool, rainy summers and moderately cold winters with precipitation occurring as rain or snow. Snowfall averages 58 inches per year. Annual average temperature is 3.4 ºC, with winter temperatures averaging -4ºC and summer temperatures averaging 10ºC. Publicly available wind maps show class 6 at Port Heiden. 2.3 Geology The soil at Port Heiden is mostly composed of glacial till. The mountains east of Port Heiden are volcanic (Detterman et al., 1981). Numerous lakes and swamps are present intermingled with tundra vegetation. 2.4 Permitting While at this time no major permitting obstacle is foreseen, state and federal agencies will need to be involved from the inception of the project. In particular, the presence of an important airport for the community will require the FAA to issue a determination of no hazard to air navigation posed by the wind turbine installation (see Section 6.0 -). Port Heiden Wind Power Feasibility Study, Rev 0 6 Section 3.0 - Preliminary Data Acquisition and Wind-Flow Modeling 3.1 Wind Flow Modeling A preliminary analysis of the wind resource at Port Heiden, Alaska was carried out to verify the availability and quality of the existing wind data, while also making sure that the wind resource was sufficient to warrant further studies. A numerical simulation was employed to investigate wind flow patterns around the village. This simulation was necessary to identify the main wind regime and variations across the territory of interest. The following extensive data was collected prior to the completion of the simulation: USGS topographical maps, Digital Elevation Maps (DEMs), and satellite imagery. Additionally, surface roughness data was acquired based on satellite MODIS mission, and analysis of aerial imagery and maps. Wind data was purchased for the automatic weather observation station (AWOS) at the Port Heiden airport (PTH). The high altitude wind data, needed to verify shear values and to get better estimates of turbine hub- height wind speeds, was collected from an existing 100-ft lattice tower housing a Bergey Excel 10 kW wind turbine at the top (denoted as “Bergey Tower”, see Figure 1). The data included wind speed readings from two anemometers at approximately 26 m AGL and wind direction readings from a wind vane at the same height, and a backup wind direction sensor at approximately 24 m. The Bergey tower data was quality assured against icing events, and manipulated to correct for tower shadowing effects. Furthermore, the data was correlated to PTH. A summary of the met-data collected at the Bergey tower can be found in Appendix A. As a result, local wind climatology was calculated accounting for terrain and surface roughness. The acquired data was in fact used in a WAsP® calculation to evaluate the wind speed trends over the topography about PH. The results are shown in Figure 2. Port Heiden Wind Power Feasibility Study, Rev 0 7 Figure 1. Bergey Tower: wind data source. Figure 2. Filled contours of wind speed at 30 m above ground level (agl) as derived from a preliminary numerical model overlaid onto USGS DRG map in the geographical area surrounding Port Heiden. Horizontal resolution is 50 m. Topography, surface roughness and other factors affect the wind flow. This calculation employs wind data from nearby PTH AWOS station and Bergey Tower (both visible on the map). Port Heiden Wind Power Feasibility Study, Rev 0 8 3.2 Site Survey and Data Acquisition A site survey was conducted in May 2010 to acquire information on the potential sites for a turbine installation in the area around Port Heiden (see Figure 3), and on the electrical load at the village. Production data logs from the power house (see Figure 4) and information on heating oil expenses for the school and Ray’s Place were acquired for the year 2009 (we are grateful to Mrs. Laura Hilton (Lake and Peninsula School District) and Mr. Kristian Carlson (City of Port Heiden) for providing support to the research). The data shows an average electric load of approximately 75 kW, peaks of 160 kW, and with a baseline energy consumption of approximately 1450 kWh/day. These estimates are thought to be still applicable for the next 10-20 year of development at the village of Port Heiden. The City of Port Heiden utilizes approximately 60,000 gallons (227,120 l) of utility diesel in a typical year. Additionally, about 7,500 gallons (28,570 l) of heating grade diesel is used for the school heating system. The generators at Port Heiden show nameplate ratings of 190 kW and 230 kW. Only one generator is working most of the time, and there is no specific heat recovery system, though the radiational and natural convection heat from the motor and generator are enough to keep the power house and annexed fire house warm during cold months. The levelized cost of unit energy (COE) varies with the oil prices, and in 2009 ranged between 0.57 and 0.75 $/kWh (not counting PCE). GPS coordinates and photos were acquired for four possible turbine sites after consulting with John Carlson at the City of Port Heiden. The sites (see also Figure 5) were chosen in proximity to the current power house and Ray’s Place, with attention to the wind power resource and local anecdotal knowledge of favorable subsurface soil conditions. Mr. Lamar Cotten (LPB Manager) and Mr. George Plumley (Planner, Dept. of Commerce, State of Alaska) were instrumental in getting high resolution terrain data (see Figure 5) that was eventually used for a refined WRA calculation.

In the background is an aerial view of the village. 500 m Port Heiden Wind Power Feasibility Study, Rev 0 11 Section 4.0 - Refined Wind Resource Assessment 4.1 Refined Wind Resource Map A refined WRA was conducted with the goal of assessing the wind regime at an altitude between 30 and 50 m above grade (AGL) at various locations across the site. The model employed high resolution terrain elevation in the immediate proximity of the village. This data was kindly provided by Mr. Lamar Cotten (LPB Manager) and Mr. George Plumley (Planner, Dept. of Commerce, State of Alaska). Wind data from the combined anemometer readings at the Bergey tower (see Figure 6-Figure 8 and Appendix A) was correlated to the long-term (last 10 years) data set at the PTH AWOS station. The correlation coefficient proved to be 0.9 (see Appendix B for more information) and this allowed the creation of a dependable long-term reference dataset (aka wind statistics) at high altitude (approximately at 30 m (100 ft) AGL). The wind climatology of the generic site at Port Heiden was then devised by weighted averaging, over the terrain and surface characteristics, the information from the two wind statistics at the PTH AWOS station (approximately 10 m or 30 feet AGL) and the Bergey tower.

The histograms represent measured turbulence intensity mean value, mean value + 1 Std.Dev, and mean value + 1.28 Std.Dev. The continuous curves show the analogous IEC standards. Results of that modeling in terms of mean annual wind speed at 30 m and 37 m AGL are given in Figure 9 and Figure 10. Port Heiden Wind Power Feasibility Study, Rev 0 14 Figure 9.

As in Figure 9 for 37 m (121 ft) agl. These results show that the general wind class for the area is between 5 and 6. 4.2 Turbine and System Alternatives Given the results of the refined WRA, four different models of turbines were modeled at each of the four proposed locations. The turbines considered in this study are the following:  Northern Power Systems Northwind NW100B/21 rated at 100 kW  Vestas V27 (marketed as A27) rated at 225 kW  Vergnet GEV-MP-C rated at 275 kW  Enercon E33 rated at 330kW Fuhrländer, a very reputable German manufacturer, quit making and supporting the 100 and 250 kW models, which therefore were not included in the analysis. Port Heiden Wind Power Feasibility Study, Rev 0 16 Enercon GmbH (Enercon) has been engaged in a legal battle with General Electric (GE) for patent infringement; there has been extensive evidence that espionage against Enercon enabled the competitor GE to patent turbine components first. Enercon was therefore effectively banned from exporting to the US till 2010. New recent cross-patent agreements and the experience of Enercon technology for wind-diesel applications make that model suitable for this study. The four models have been selected as among the most reliable and effective machines for the conditions at Port Heiden. They are either IEC class I or class II, with turbulence category A or B. From Figure 8, it can be seen that turbine design category B is adequate for Port Heiden. ASCE 7-05 [4] recommends a 50-yr design wind speed of 58 m/s at 10 m AGL, which would translate into 65-66 m/s gusts at hub-heights, making it an IEC class I site. The Enercon E33 is the only class I machine. With the exception of the E33 and the Vergnet GEV MP-C, which could be lowered and protected during a strong wind storm, the other models would likely suffer from some considerable damage in such an event. For the expected life of the project (20 years), the probability of exposure to such a catastrophic event is on the order of 30 percent. This value is significant enough to warrant more discussion with the manufacturers to verify the expected damage and costs of repair under a 65 m/s (approximately 130 kts) wind gust. Power curves for the four machines are given in Figure 11. Figure 11. Power curves for the four wind turbine models. Top row: NW100B/21, Vestas A27; bottom row: Vergnet GEV MP-C, Enercon E33. The four turbines differ in size, tower arrangement, and control systems. The Northwind and Enercon turbines do not have a gearbox, with simplified maintenance. Port Heiden Wind Power Feasibility Study, Rev 0 17 The Northwind 100 is the only turbine in the group which does not have pitch control. Pitch control assures an optimal energy capture at various wind speeds, regulates the RPMs at the highest wind speeds, and protects the machine by feathering the blades in potentially damaging strong wind events. At the same time, the moving parts are more numerous and the possibility of failures increases. The Vergnet turbine is mounted on a guyed tubular tower that can be lowered for maintenance and in case of forecasted strong wind storms. All the other models come with standard monopole towers, which let the operator climb inside a weather-protected environment. The NW100 B/21 could also be potentially mounted on an innovative lattice tower system (Parafold) which allows the turbine to be lowered with a winch, does not require heavy cranes for the installation, and allows for simplified foundations. At the time of this report, Northern Power Systems would not release the costs of the individual components, and is not willing to sell an incomplete package with only nacelle plus blades. Therefore no reduction in costs is considered in the economic analysis, but during procurement phase this could be an option to re- evaluate. Regardless of the selected model alternative, the turbine generator would produce 3-phase, 60-hertz, 480-volt electricity. The 480-volt electrical output from the generator would be converted to 12.5 kilovolts (kV) by a step-up transformer and then connected to the village electrical grid by a 12.5 kV transmission line. The wind-power system for Port Heiden should supply (to the extent possible) the thermal load that is currently supplied by diesel furnaces at the school and/or Ray’s Place. This would allow the system to reduce even further the cost of unit energy, making it more attractive. Thus, the proposed wind-power system includes an electric hot water boiler, a supervisory control system, and a secondary load controller, which supply the thermal load during those times when adequate wind generated power is in excess of demand. 4.3 Annual Energy Production Estimates In Appendix C, the four turbines are compared in terms of energy yield, or annual energy productions (AEPs), at the four proposed sites with a fixed hub-height of 30 m. For completion, the wind distribution and energy distribution for site 01 is shown again in Figure 12. Port Heiden Wind Power Feasibility Study, Rev 0 18 Figure 12. Wind speed distribution, energy sector distribution, and wind rose at proposed site 01 (30 m or 98 ft agl). Table 1 summarizes the AEPs and CFs for the various turbines at the various sites assuming an overall loss of 10 percent. Table 1. AEPs and CFs for the four models at a hub-height of 30 m at the various proposed site locations. A 10 percent overall production loss is assumed, due to: electrical losses, blade degradation, power curve uncertainties, availability, etc. AEP (MWh) / CF Site 01 Site 02 Site 03 Site 04 Turbine Model AEP (MWh) CF AEP (MWh) CF AEP (MWh) CF AEP (MWh) CF Northwind 100B/21 298 0.340 295 0.337 297 0.339 285 0.325  Vestas A27 638 0.324 630 0.320 635 0.322 605 0.307  Vergnet GEV-MP-C 777 0.323 768 0.319 774 0.321 742 0.308  Enercon E33 1029 0.356 1017 0.352 1025 0.355 983 0.340  The variation in AEP (CF) across the first three sites (see Table 1) is about 1.5 percent with respect to the average value, and therefore it may be considered within modeling errors (1-3 percent). The fourth site shows 4.5 percent less production than the others, and therefore it should be left as last resort in case none of the other sites are permitted. In general, however, the wind resource is fairly uniform at Port Heiden, allowing for some flexibility in the final siting. Note that the Vergnet and Enercon turbines normally utilize taller towers (55 m and 37 m respectively), and they are penalized with a 30 m hub-height; the theoretical AEP is still given in Table 1 for Port Heiden Wind Power Feasibility Study, Rev 0 19 completeness, but these machines would be installed on taller towers. A taller tower may, however, have some consequences for FAA approvals. The A27 comes standard with a 32 m tower; therefore no significant differences are expected when compared to a 30 m hub-height. The Enercon E33 is the most efficient (highest predicted capacity factor) machine at the four sites under examination, followed by the Northwind 100B/21. The much larger power rating may require additional electronics and controllers to secure a stable village grid under a high penetration level, but may lead to substantial savings in diesel fuel costs (see Section 5.0 -). The Northwind 100B/21 would require a relatively simpler control system to interface with the diesel power plant in a medium wind power penetration level. The other turbines fall in the middle of this range. Table 2 shows analogous data to Table 1 for a fixed hub-height of 37 m, and more detailed data is available in Appendix D. Figure 13. As in Figure 12, for 37 m (121 ft) agl. Port Heiden Wind Power Feasibility Study, Rev 0 20 Table 2. As for 37 m Hub-Height.

Finally, for the largest turbines (Enercon and Vergnet models), it makes sense to investigate an even higher hub-height of 50 m. A calculation has been carried out at Site 01 and Site 04 (see Appendix E) for those larger machines and summary of AEPs and CFs is given in Table 3. Table 3.

Port Heiden Wind Power Feasibility Study, Rev 0 21 Section 5.0 - Economic Analysis 5.1 Inputs and Assumptions The Economic analysis of a wind power installation at Port Heiden was carried out for ’site 01’, since it has the most favorable wind conditions among the four locations examined. If the location for the turbine installation had to change slightly, however, no significant changes are expected. The actual discount rate assumed is 2.9 percent, with a nominal interest rate and inflation rate of 5 and 2 percent respectively. The project lifetime is 20 years. It is assumed that the power house will stay at its current location, or be moved closer to Ray’s place. No diesel-generator heat recovery system (as current) is assumed, though a 5 percent heat recovery ratio is assigned to the diesel generators to account for the beneficial heating of the power-house and annexed fire house. The interconnection of the turbine will occur within 0.25 miles of the turbine location. A separate supervisory controller is needed for high levels of wind penetration, and therefore with turbines other than one single NW100B/21. It is assumed that an electric boiler would be paired with the existing heating system at the school or at Ray’s Place. The electric boiler would be governed by a dedicated secondary load controller to utilize excess wind energy coming from the turbine when the electric load is low, thus allowing a further reduction in fuel costs for heating. The seasonal electric load at Port Heiden including the monthly maximum, average daily high, monthly mean, average daily low, and monthly minimum values, is given in Figure 14. It is estimated that the average electricity consumption is 1450 kWh/day with average load of 75 kW and peaks to 160 kW. Figure 14. Monthly-averaged electrical load at Port Heiden. The thermal load at the school (see Figure 15) has been estimated based on diesel sales data provided by the City of Port Heiden and LPSD, and on data reported in [2]. About 7,500 gallons/yr (28,600 l/yr) of heating oil are consumed at the school, and it is assumed that the thermal load at Ray’s Place is comparable to that of the school. The average thermal load is estimated to be 950 kWh per day. Port Heiden Wind Power Feasibility Study, Rev 0 22 Figure 15. As in Figure 14, for the thermal load at the school in Port Heiden. 5.2 System Alternatives Analyzed Table 4. Alternatives analyzed in the economic model. Turbine Model Hub-Heights (m) Qty.

It was decided to limit the analysis of the 30 m hub-heights only to the NW100B/21 and the Vestas A27; the analysis of the 50 (55) m hub-height to the E33 (GEV MP-C) (see Table 4). 5.3 Estimated Capital and Replacement Costs An opinion of probable project costs for the various alternatives was developed based on July 2010 US dollars. The opinion of probable project costs includes construction, engineering, and contingency. Overall project cost was established by adding engineering, permitting, and legal fees. Engineering costs include preliminary and final design, procurement, construction management, and administration. Table 5 shows the estimated costs for the installation of the various alternatives. The data were obtained after consulting with the turbine vendors and the following construction and transportation contractors: GeoTek Alaska, Inc., STG, Inc., Sustainable Automation Inc., Northland Services Marine Transportation, and Bellavance Trucking. These cost estimates should be considered accurate to within plus or minus 30 percent at the time of project implementation. Because of the remoteness of Port Heiden, most of the capital costs come from having to transport personnel, materials, components, and special construction equipment to the site. The capital cost would increase or decrease depending on crude oil price fluctuations, as those affect transportation and manufacturing processes. However, there is very little information at this point to provide a solid justification to changes in the current estimates that are provided with a ±25% margin.

This is an average salary for a maintenance mechanic at the power house. $1.5 per operational hour is the additional rate assumed for the O&M of diesel generators. Port Heiden Wind Power Feasibility Study, Rev 0 24 For the wind system, an $8,500/yr O&M cost per installed turbine is assumed; this includes salary amounting to 1 day/month for a local mechanic plus 2 days every three months for a specialized mechanic from Anchorage and airfares. If two or three turbines are installed, the O&M is calculated at $15,500 and $22,400 respectively. The overall diesel generator O&M will be less in the combined system due to reduced diesel usage, however the salary of the local mechanic will be higher for the additional maintenance tasks at the wind turbine. The current O&M cost is based on information provided by the City of Port Heiden and by the Lake and Peninsula School District (LPSD) for Chignik Lake (a similar community in the Borough). 5.5 Estimated Diesel Prices Four different values for delivered diesel prices were assumed: $/l, 0.99, 1.360, 1.450, 1.65 ($/gal 3.75, 5.15, 5.50, 6.25). The current values at the time of compiling this report is approximately $/gal 5.15 (City of Port Heiden data). The largest estimates are in line with [2] for projected long-term oil price of $110/bbl and $125/bbl; the lowest value is scaled linearly with a projected oil-price of $75/bbl. Following [2], the heating oil prices were obtained by adding $1.2/gal to the utility diesel price, for current and long-term oil prices, and then scaled proportionally to the assumed crude oil price for the lowest price scenario of $75/bbl. 5.6 Economic Analysis Results The software program HOMER© [1] was employed to simulate the economic performance of the various turbines and at multiple hub-heights (30, 37, 50, and 55 m). In Appendices F-J, complete output reports from the program are provided for the various system alternatives. Note that in HOMER©, a reduced annual mean wind speed was assigned in order to account for 10 percent losses as discussed in Section 4.2. The HOMER© analysis produces several economic measures that show the value of the difference between the wind/diesel alternative under consideration and the current diesel-only system, taking into account the 20-year life cycle costs of both systems. Definitions of the economic measures shown in the following sections are as follows:  The present worth is the difference between the net present cost of the alternative system and the diesel-only system, where the net present cost is the present value of all system costs incurred over the project lifetime (including capital costs, replacement costs, O&M costs and fuel costs) minus salvage value. Present worth shows how much the alternative system saves over the project lifetime compared to the diesel-only system, and is the primary measure for comparing the economic feasibility of the two systems. The present worth represents the avoided cost over the life of the project when operating the alternative system rather than the current system.  The discounted payback period is how long it would take to recover the initial investment in the alternative system using the assumed rates for interest (5 percent) and inflation (2 percent).  The annual worth is the present worth multiplied by the capital recovery factor, which is a ratio used to calculate the present value of a series of equal annual cash flows.  The Internal Rate of Return is the discount rate that makes the present value of the difference of the two cash flow sequences equal to zero.  The levelized cost of energy (COE) is the average cost per kWh of useful electrical energy produced by the system. This is calculated by dividing the annualized cost of producing electricity (the total Port Heiden Wind Power Feasibility Study, Rev 0 25 annualized cost minus the cost of serving the thermal load) by the total annual electric energy production.  The benefit/cost ratios for each alternative compared to the diesel-only system were calculated by adding the net present cost to the present worth and then dividing by the net present cost. 5.6.1 Results for 37 m hub-heights The following Table 8 through Table 11 show the economic measures for the select wind/diesel alternatives, assuming four different values of diesel prices (see Section 5.5). The color coding associated with the benefit/cost ratio identifies with green the ‘best economic alternative’, cyan ‘second best’, orange the marginal, and red the unfeasible alternative. Note that the current COE values are higher than those predicted in [2] due to the absence of heat recovery systems in the diesel power plant at Port Heiden. Table 8.

The Enercon E33 is the most suitable option for Port Heiden according to the results of the economic model. For the largest diesel price, the Enercon E33 (at 37m hub height) would save almost $1,320,000 in diesel costs throughout the life of the project, while the A27 and GEV MP-C would approximately save $910,000 and $986,000 respectively. For a diesel price of $5.5/gal, the Enercon E33 would save almost $927,000, while the A27 and GEV MP- C would approximately save $656,000 and $600,000 respectively. At the current diesel price, the same three models would attain savings ranging from $750,400 to $460,000. The COE for the E33 varies from 0.523$/kWh to 0.569$/kWh as the price of diesel changes from $5.15/gal to $6.25/gal, with a projected reduction with respect to the diesel-only system ranging 0.9 to 0.16$/kWh.. Port Heiden Wind Power Feasibility Study, Rev 0 27 The COE for the A27 and GEV MP-C varies from 0.55$/kWh to 0.62$/kWh as the price of diesel changes from $5.15/gal to $6.25/gal, with a projected reduction with respect to the diesel-only system ranging 0.06 to 0.12$/kWh.. Either a pair (for diesel price of $5.5/gal and $6.25/gal) or three NW 100B/21 turbines (for a diesel price of $6.25/gal) may be a marginal alternative in the highest diesel-price scenarios. For the unlikely scenario corresponding to the lowest diesel price, however, no system alternative is competitive with the current system. 5.6.2 Results for 30 m hub-heights Given the previous results for the 37 m hub-heights, every effort should be made to maintain the highest hub-heights possible. However, if FAA limitations are imposed, lower hub-heights may be necessary. For this reason, in this section we offer results (see Table 12 - Table 15) of the economic analysis of the Northwind100B/21 and Vestas A-27 at 30 m hub-height. The other machines are deemed too large to be suitably placed at such low a hub-height. The cost variation in foundations and towers is not significant enough between these two heights to justify changes in assumed capital costs. Table 12.

At this lower hub-height, only the Vestas A27 is a valid alternative with a diesel price of $5.5/gal or $6.25, while only marginal at a price of $5.15/gal. Savings in displaced fuel costs range from $310,600 to $730,000, and the levelized COE ranges from .578 to .643$/kWh with a reduction of approximately 0.04 to 0.09$/kWh with respect to the diesel-only system. 5.6.3 Results for 50 and 55 m hub-heights As mentioned in the previous sections, a higher hub-height would yield more energy production on an annual basis, and especially for the largest machines (Vergnet GEV MP-C and Enercon E33). The cost of a taller tower and deeper foundation is included in this analysis through an increase in capital cost of $20,000 and $70,000 for the Vergnet and the Enercon models respectively. The Vergnet still uses shallow foundations for the anchors thanks to the tiltable tower. Port Heiden Wind Power Feasibility Study, Rev 0 29 Table 16.

Port Heiden Wind Power Feasibility Study, Rev 0 30 For the lowest diesel price, the two systems are nearly identical from an economic perspective, with only approximately $35,000 in overall savings over the life of the project, and no significant reduction in COE with respect to the diesel-only system. For the current diesel price, the savings in displaced fuel costs are significant ($737,000-$835,000), and the COE is reduced by about 0.09-0.10$/kWh. For the $5.5/gal ($6.25/gal) diesel price, the E33 achieves a COE of about 0.525$/kWh (0.554/kWh, almost a 0.18$/kWh reduction with respect to the current system) with a total savings over the life of the project of about $1,020,000 ($1,436,799). The GEV MP-C achieves a COE of about 0.54$/kWh (0.576/kWh, almost a 0.16$/kWh reduction with respect to the current system) with a total savings over the life of the project of about $901,300 ($1,265,783). Port Heiden Wind Power Feasibility Study, Rev 0 31 Section 6.0 - Environmental and Construction Permitting In this Section, we describe the necessary steps for the permitting of the project, which includes Environmental and Building Permitting. There are a number of agencies that will have jurisdiction on the project. While the project is on private land belonging to the City of Port Heiden, if federal or state actions such as funding or issuance of permits or licenses are involved, then the appropriate federal and state agencies will need to be consulted to start the regulatory permitting process. Where possible, an estimate is given of the time required for the individual permits. 6.1 Soil and Foundation Requirements Historical data from well drilling in the general geographic area reported sand and pumice deposits that extend to 15-25 feet below ground surface (bgs) underlain by a layer of silty clay to silty gravel which extends to 50-90 feet bgs, and saturated coarse sand and gravel layers below that. A dedicated geotechnical investigation is recommended and budgeted in the economic analysis (see Section 5.0 -). The geotechnical report will help the engineering of the foundation design to be approved within the construction permitting. Estimated time for geotechnical investigations: 30 days from commission. 6.2 FAA Permitting The FAA (Federal Aviation Authority) will need to release a “determination to no hazard to navigation” for the wind turbine at the selected site. A FAA Form SF 7460-1 will need to be filed in advance of other activities, since the FAA has shown extensive delays in their responses in the past. We expect it will be necessary to coordinate with the Anchorage (Alaskan Region) office. Estimated time for permit: 30-90 days from filing. 6.3 Construction Permitting Construction General Permit (CGP) will be needed from Alaska Department of Environmental Conservation (ADEC) for the construction of the project. In order to get this permit, a Storm Water Pollution Prevention Plan (SWPP) will need to be completed, which will include measures to mitigate detrimental effects to the environment during construction. This includes digging and pouring of foundations, tower erection, transformer construction, power line burial and potential power line poles along the road from the site to the interconnection point. Note that the impacted area is foreseen to be larger than one acre (threshold value for this permitting requirement) due to the transmission line corridor from the wind turbine site to the interconnection point. A Notice of Intent (NOI) must be submitted to Environmental Protection Agency (EPA) within this phase. Additionally, consultations with the US Fish and Wildlife Service and the State Historic Preservation Office will be required, together with the agencies’ determinations of “no significant effect to species or historical environment” as per Sections 6.5 and 6.6. Other building permits and electrical reviews may be needed by the entity in charge of the utility at the village. The executive mechanical, civil, and electrical drawings will need to be stamped by one or more licensed professional engineers in the State of Alaska. Port Heiden Wind Power Feasibility Study, Rev 0 32 Note that LPB will be required to assist in the determination of these further requirements. Estimated time for permit: 90 days from filing. 6.4 Alaska Coastal Management Program (ACMP) Port Heiden is entirely included within the coastal boundaries established by the Alaska Department of Natural Resources (ADNR), Division of Coastal and Ocean Management (DCOM). Discussion with ADNR/ACMP will include a Coastal Project Questionnaire (CPQ) to be filled out in order to identify other agencies that may be required to be consulted regarding the project. If at least one state or federal permit is required, a complete ACMP consistency review will be necessary. Estimated time for permit: 90 days from filing. 6.5 US Fish and Wildlife Service (USFWS) and Alaska Department of Fish and Game (ADF&G): The USFWS will need to be contacted in the development of the project. Initially, a review will be conducted of the draft guidelines that the Alaska Regional Office of USFWS has issued. Then contacts will be established with the local Fish and Game offices (ADF&G), and village individuals to verify that there are no bird migratory paths, roosting or nesting habitat of endangered plant or animal species that are affected by the installation of the wind turbine and associated power lines. Site soil preparation may involve some coordination in order to comply with USFWS guidelines. It is known that sea-gulls and eagles are present in the area; however, no eagle nest was observed at the selected site for the wind turbine, nor is the site considered a bird gathering place. The USFWS may require pre and post-construction observation periods based on these observations and will contact ADF&G on this regard. As we expect to install one wind turbine, the impact to any bird or mammal species should be insignificant, but the USFWS will need to be made aware of the project to address issues associated with potential wildlife fatalities during operation. 6.6 State Historic Preservation Office (SHPO) and Office of History and Archeology (OHA) A letter from SHPO stating that “no historic properties will be adversely affected by the project” will be required. An archeological survey may be required for access and construction footprint. Procedures will need to be coordinated with a state archeologist. Estimated time for permit: 30 days from filing. 6.7 Land Uses and Rights-of-Way No federal land is expected to be affected by the project, therefore only a written notice to proceed by the native corporation and the City of Port Heiden is required to allow project implementation. If other private land is involved, further written authorizations will be required. Note that LPB will be required to assist in the determination of Land Status for the areas of interest to the project. 6.8 Wetlands and Other Waters We do not foresee requiring any further permit with the US Army Corps of Engineers, since the project will not involve any construction activities in jurisdictional wetlands. Port Heiden Wind Power Feasibility Study, Rev 0 33 However, a jurisdictional wetland survey will be needed to determine the existence of any such wetlands within the project area that might be impacted by the project. 6.9 National Environmental Policy Act Review (NEPA) Although, it is not likely that a full environmental impact statement (EIS) will be required under the National Environmental Policy Act, the preparation of an environmental assessment (EA) would most likely be required for federal and state agencies permitting requirements. The EA is an abbreviated NEPA process document that is intended to assess the potential environmental impacts of the project, provide for mitigation as required and to confirm minimal impact to the environment. The EA would be used by the regulatory agency(s) to issue a Finding of No Significant Impact (FONSI) to the environment, thereby circumventing the need for an EIS. Note that LPB will be required to assist in this determination. 6.10 Tentative Cost Estimates Associated with Environmental & Construction Permitting It is not trivial to assess the costs at this stage of the project, especially since there are many unknowns in terms of effective permits required. Per client’s request, however, we are offering a best estimate of the costs based on the current knowledge of the factors involved in this project. This estimate may change vastly in either direction when the project implementation gets underway. FAA permitting: $1,000 Construction Permitting: $8,700 ACMP Permitting: $1,500 USFWS-ADF&G Consultation: $3,000 SHPO-OHA Consultation: $6,000 Land Uses Rights-of-Way: $1,300 Wetlands Surveying: $4,300 Estimated total cost (July 2010 US$): $25,800 Note that this estimate does not include preparation of an EA as part of the NEPA review process (if needed). Port Heiden Wind Power Feasibility Study, Rev 0 34 Section 7.0 - Conclusions and Recommendations The high cost of electricity generation using diesel fuel at Port Heiden is a strong incentive to examine alternative means of generating electricity, such as wind-power. However, due to the remoteness of Port Heiden, some logistical challenges that make a wind-power project more onerous need to be overcome to be economically feasible. This study carried out a preliminary and a detailed wind resource assessment (WRA), a site survey to identify suitability of wind turbine installations, and the collection of various data as inputs to an economic analysis, namely: village electrical and thermal load data, village fuel expenses, vendors’ and contractors’ information and quotations. Also included in this study was a review of the permitting requirements. Following a site visit and an initial screening process, four sites were selected for a more detailed analysis, including a conceptual project layout, an estimate of power generation, a preliminary cost estimate, and an analysis of the economic feasibility. 7.1 Wind Feasibility Study Conclusions The following conclusions of the present study can be drawn:  The wind at Port Heiden is in upper class 5, with little variation across the area of interest.  A mid-to-high penetration level is the only economically viable option for wind at Port Heiden, which implies a relatively sophisticated primary and secondary load control system to be implemented in addition to heat storage solutions at the school or at Ray’s Place.  The economics favor the highest hub heights, but with diminishing return on investment due to the higher costs of tower and foundation. A minimum of 37 m should be sought for any of the machines, for example: The Vestas A27 shows an increase in net savings over the lifetime of the project of about 20- 30 percent (accounting for additional costs of a taller tower not included in the analysis). The Enercon E33 shows an increase in net savings over the lifetime of the project of about 10 percent going from 37 to 50 m.  Initial investments for a wind turbine installation at Port Heiden range between $1.2M and $2M, or $2.8M for multiple turbine installations. These cost estimates should be considered accurate to within plus or minus 30%.  The per-installed-kW cost ranges between $6,000 and $12,000 depending on the model and quantity of turbines.  For the lowest $3.75/gal diesel price analyzed, no wind power system is economically competitive.  The COE can be lowered from 0.04 to 0.18$/kWh (diesel prices of $5.15/gal through $6.25/gal) with respect to the diesel-only system, depending on the turbine model and hub-height.  The Enercon E33 is the most suitable model for the economics at Port Heiden. If installed at 37 m, the COE is reduced to 0.523 $/kWh (0.537$/kWh;0.569$/kWh), a decrease of 0.09$/kWh (0.12$/kWh;0.16$/kWh) with respect to the diesel-only system, with an overall savings due to avoided fuel costs of $750,400 ($927,500;$1,321,100) when the diesel price is $5.15/gal (5.5$/gal;6.25$/gal).  A valid alternative is the Vestas A27, which performs economically well at lower and higher hub-heights. The A27 is a new machine (not reconditioned), with support from a European manufacturer, and a proven track-record. For a 37 m hub-height, at a diesel price of $5.15/gal (5.5$/gal;6.25$/gal), the COE is reduced to 0.56 $/kWh (0.58$/kWh;0.62$/kWh), a decrease of 0.06$/kWh (0.08$/kWh;0.115$/kWh) with respect to the diesel-only system, with an overall savings due to avoided fuel costs of $461,000 ($600,400;$986,400). Port Heiden Wind Power Feasibility Study, Rev 0 35  The A27 installed at 30 m hub-height achieves a COE of 0.58 $/kWh (0.6$/kWh;0.64$/kWh), a decrease of 0.04$/kWh (0.06$/kWh;0.09$/kWh) with respect to the diesel-only system, with an overall savings due to avoided fuel costs of $310,000 ($441,000;$730,000) when the diesel price is $5.15/gal (5.5$/gal;6.25$/gal).  The Vergnet GEV MP-C is also a proven technology which could fit well at Port Heiden. The standard Vergnet tower is a guyed tower which can be lowered for maintenance and for protection in case of strong wind events. Icing and harsh meteorological conditions in Alaska may constitute a challenge to the operations of a tilt able tower, though that presents an advantage in terms of construction, since it does not require heavy cranes. If installed at 37 m, the GEV MP-C achieves a COE of 0.55 $/kWh (0.57$/kWh;0.611$/kWh), a decrease of 0.06$/kWh (0.08$/kWh;0.12$/kWh) with respect to the diesel- only system, with an overall savings due to avoided fuel costs of $507,000 ($656,000;$986,400) when the diesel price is $5.15/gal (5.5$/gal;6.25$/gal).  At a hub height of 50 m, the E33 yields a COE of 0.51 $/kWh (0.52$/kWh;0.55$/kWh), which is a decrease of 0.10$/kWh (0.13$/kWh;0.18$/kWh) with respect to the diesel-only system, with an overall savings due to avoided fuel costs of $835,400 ($1,022,000;$1,436,800) when the diesel price is $5.15/gal (5.5$/gal;6.25$/gal).  At a hub height of 55m, the GEV MP-C yields a COE of 0.52 $/kWh (0.54$/kWh;0.58$/kWh), which is a decrease of 0.09$/kWh (0.11$/kWh;0.16$/kWh) with respect to the diesel-only system, with an overall savings due to avoided fuel costs of $737,300 ($901,300;$1,265,800) when the diesel price is $5.15/gal (5.5$/gal;$6.25$/gal).  While the NW 100B/21 does not achieve feasibility status in the economic model (except in the 37 m hub-height two-turbine configuration and diesel price equal or greater than $5.5/gal), it should be emphasized that the manufacturer and support is in the US, and that several installations in Alaska have proven very reliable so far (less than a decade). 7.2 Other Relevant Remarks  The choice of turbine model should account for accessibility to spare parts. It is reasonable to assume that the NW100B/21 has some advantage there, though difficult to quantify. Due to the remoteness of Port Heiden, an inventory of spare parts should be acquired at the time of project commissioning for any given model.  The possibility of a catastrophic failure needs to be evaluated with the turbine manufacturers. The harsh wind regime is such that a damaging wind gust may be encountered with a probability of 30 percent throughout the lifetime of the project. The turbine manufacturer will need to provide a risk assessment based on the predicted extreme wind conditions and an evaluation of potential damage and related costs to be expected.  For any of the alternatives, costs for a wind power project will be high due to the physical setting. Material transport and construction costs will be high, since the contractors capable of performing the work are located in Anchorage.  Construction materials and equipment for all alternatives will need to be shipped to Port Heiden via sea. The absence of a dock at Port Heiden may complicate logistics and costs.  Construction may need to take place during the winter to avoid road system failure under heavy construction equipment weight. Repairs to the existing roads, and new road constructions will likely be needed.  The small size of the job will not favor a reduction of construction costs under bidding, because only a limited number of contractors are likely to submit bids.  While permitting is not seen as a major obstacles, the number of local, state, and federal agencies that need to be involved is large, and if the project is selected, permitting procedures will need to be established early on. Port Heiden Wind Power Feasibility Study, Rev 0 36 7.3 Recommendations for Future Activities If LPB decides to continue with the implementation of the wind power project at this site, recommendations include:  Investigate whether suitable financing is available to develop a wind power project at Port Heiden with the economics as illustrated in this report  In case of positive outcome of the previous point:  Initiate contacts with Enercon and other vendors.  Identify a project manager and a firm to oversee the engineering.  Initiate geotechnical investigations to assess the requirements for a sound foundation.  Identify other potential construction projects at Port Heiden for sharing of costs associated with construction activities, transportation and logistics  Initiate permitting procedures Port Heiden Wind Power Feasibility Study, Rev 0 37 Section 8.0 - References ASCE Standard ASCE/SEI 7-05, Minimum Design Loads for Buildings and Other Structures, ASCE 2005.

Productions are without wake losses. For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2. The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003. Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.

Productions are without wake losses. For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2. The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.

Productions are without wake losses. For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2. The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.

Productions are without wake losses. For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2. The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.

Productions are without wake losses. For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2. The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003. Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.

Productions are without wake losses. For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2. The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.
