Summary Energy yield calculations for the three possible wind farm areas in Aust-Agder are presented in this report. The wind data used for the calculations are from the meso-scale model WRF. The mean wind speed at hub height 119 m is estimated to be 7.8 m/s for Storehei, 7.3 m/s for Oddeheia and 7.6 m/s for Bjelkeberget. Due to the short distance between the wind farms, the neighboring parks will cause increased wake losses. The reduction in net energy yield is approximately 0.2 % for Storehei, and approximately 1% for Oddeheia and Bjelkeberget, assuming that all the three sections are build. In addition to the wake losses additional losses of 13 % for Storehei, and 12 % for Oddeheia and Bjelkeberget is assumed. The energy yield calculations are summarized below.

The uncertainty of the energy yield calculations is expected to be about 30 %. The high uncertainty level is due to the use of model data instead of wind measurements, the micro scale modeling in relatively complex terrain, the energy loss assumptions and the energy sensitivity.

1 Introduction

This report describes the pre-analyses for the energy yield at three wind farm sites in Birkenes, Aust-Agder. The wind farm areas are shown in Figure 1-1. The wind farms are located close to each other. The wind map for Norway shows that the wind conditions in the three park areas are similar. The elevation of the project area at Bjelkeberget is on average 325 m.a.s.l., the average elevation at Storheia is 354 m.a.sl. and the average elevation at Oddeheia is 317 m.a.sl.. The landscape is characterized by forested hills. The terrain within the wind farm areas are relatively flat, but there are some complex terrain in the surroundings of the wind farms.

The layouts are specified by E-On. The layout at Bjelkberget consists of 18 turbines, the layout at Storheia consist of 29 turbines and the layout at Oddeheia consists of 11 turbines. The total installed capacity of each wind farm is 54 MW, 33 MW and 87 MW for Bjelkberget, Storheia and Oddeheia respectively.

In this report the data used for the analyses are presented. Thereafter the wind climate at each of the wind farms is presented with key parameters and wind maps. In section 5 the icing map of the region is presented. Section 6 and section 7 include the energy yield calculations for each of the wind farms and a discussion of the uncertainty for the energy yield calculations.

2 Input data Data from the meso-scale meteorological model WRF (Weather Research and Forecast model) are used for modeling the wind conditions at Storeheia, Oddeheia and Bjelkberget. The model is described in detail and further references are given in Appendix A.

The terrain is described with height contours with equidistance equal to 5 m within and close to the park area. The roughness classifications are based aerial photos from www.statkart.no and from pictures provided by the customer.

The turbine positions for the three areas are specified by the customer. The energy yield calculations are carried out for three turbine models. The turbine specifications used for the calculations are either from the EMD database (EMD 2008) or from E-On.

The wind farms are located in a forested area. Representatives from Kjeller Vindteknikk have not been at the sites to evaluate the forest, but some pictures from a site visit are provided. Based on the provided pictures and the aerial photos the zero displacement height is estimated to 5 m.

3 Wind analysis method

Time series from the WRF model are used for calculation of the wind conditions in the area. A time series from a model run with geographical resolution of 1 km * 1 km and length of one year and a time series from a model run with geographical resolution of 4 km * 4 km with length of 12 years are used for the calculations. The short time series with high spatial resolution are expected to give the best description of the local wind climate at the sites. To estimate the expected long term wind climate, the short time series are long term corrected with the time series with length of 12 years. The long term correction of the wind climate is carried out with the sector bin method (Harstveit 2004). The geographical position of the model grid points and the length of the time series are given in Table 3-1. The wind data from WRF are from a model level with height 113 m above zero displacement height in the meso-scale model.

Table 3-1: WRF model grid points used for the analysis.

As noted in section 2 we have assumed a 5 m displacement height due to the forest of the area. The WRF model is not taking the displacement height explicitly into account in the calculations. In areas with forest, the height level of the calculated WRF data must be interpreted as above the displacement height and not the ground level. For example, for WRF data extracted from the 100 m model level, the zero displacement height of 10 m must be added to find the valid level above ground, which in this case will correspond to 110 m.

The local wind maps for the different areas have been calculated with the micro-scale model WindSim (WindSim u.d.) The long-term corrected wind statistics from the WRF model is used as input parameter for the calculations. Both the vertical and the horizontal extrapolation are done in the micro-scale model. The roughness classification is summarized in Table 3-2. The roughness classification follows standard roughness values (WAsP Manual 1993), which also applies for other micro-scale models.

WindSim is selected as the appropriate micro-scale model for these sites due to the relatively complex terrain in the surroundings of the wind farms. The areas within the park limits are flat for all the three areas, however the complex terrain around the parks will influence the wind conditions within the parks. The effects of the complex terrain, such as lowered wind speed due to turbulence, is expected to be captured in the calculations done in the CFD micro-scale model. Wind maps are calculated for several meso-scale wind statistics and different placements of the wind statistics are evaluated. The wind statistics which resulted in a coherent result for the wind farms were evaluated as most reliable and selected for the study. The placement of the meso-scale wind statistics are shown in Figure 5

KVT/ALL/2013/R003 rev.1

3-1. Number of wind statistics used for the analysis depends on the size of the wind farm area and the possibility to use the WRF wind statistics in the micro-scale model. For Bjelkeberget and Storehei the final wind maps are based on all the wind statistics within each wind farm area. The wind maps are weighted with respect to the distance to the placement of the wind statistics.

5 Icing The icing conditions for the region is taken from “Vindkart for Norge” (Byrkjedal and Åkervik 2009), and is based on model results from the WRF model. It is valid for 80 m above ground and it has a horizontal resolution of 50 m x 50 m. The ice map is shown in Figure 5-1. Active icing is defined as formation of more than 10 g/m ice per hour. From the figure we see that expected time with icing is between 101 and 200 hours per year for Oddeheia and Bjelkeberget at 80 m above ground. For Storehei more time with active icing is expected, for large share of the area the time with active icing is expected to be between 201 and 300 hours. A first preliminary estimate indicates that the energy losses due to icing could be about 3 % for Storehei, and 2 % for Oddeheia and Bjelkeberget. Considerable uncertainty is linked to these estimates and more detailed studies of the ice losses are recommended at a later stage. Note also that turbines with de-icing or anti-icing systems can reduce the ice losses.

The time with active icing is expected to increase with height above ground. A first estimate is that the expected time with icing will be in the same range for the hub heights as for 80 m above ground, for which the model results are valid. A calculation of the icing map at hub height is outside the scope of this analysis.

6 Energy yield calculations The software WindPRO 2.8 is used for the energy yield calculations. The energy yield calculations are based on the wind conditions described in the previous sections. The air density is based on climatic statistics from the EMD database for Kjevik in Aust-Agder. The layouts are specified by E.ON for each wind farm area. The coordinates for the wind turbines for each area are given in WindPRO printouts in Appendix D. Energy yield calculations are done for three turbine alternatives specified by E.ON, given in Table 6-1. The turbine specifications, power curve and trust curve, are from the EMD database for the Vestas and RePower turbine. For the Siemens turbine, the specifications are provided by E-On. The turbine specifications are given in Appendix C.

Table 6-1: Wind turbines evaluated for the three wind farms, Storehei, Oddeheia and Bjelkeberget. Turbine Capacity [MW] Hub height [m] Diameter [m] IEC class Vestas V112 3.1 119 112 III A Siemens SWT-3.0-113 3.0 119 113 II B RePower 3.2M114 3.2 119 114 II A

The presented wind maps in section 4 show that the wind speed is expected to be higher than the IEC recommendation for mean wind speed for class III for some of the turbine locations. The Siemens and the RePower turbines are class II turbines for the used hub height, but the Vestas turbine is at present a class III turbine for 119 m hub height, as summarized in Table 6-2. There is however reason to believe that a more detailed calculation of the life time for the turbines will show that the Vestas turbine is sutable as well. It is the overall load for the turbines which determines the final choice of turbine type. The overall load will depend on several factors; mean wind speed, extreme wind speed, turbulence, and icing among others. Based on meteorological general knowledge, the extreme wind speed is not expected to be determining for the IEC classification at these sites. There might be some turbulence due to the forest and the relatively complex terrain in the surroundings of the parks. However, the turbulence is not expected to be determining for the classification either. The IEC classification can be done when wind measurements are performed at the sites. When wind measurements are available, the wind shear can be calculated at each site. When this parameter is calculated the advantages with respect to energy production and the costs of different hub heights should be evaluated.

The energy yield calculations for each of the wind farms are given in the following subsections.

For all the wind farm areas two calculations are performed for each turbine alternative. One calculation with only the specific park area and one calculation where the wake effects from the neighboring wind farms are included. For the calculations with the wake effect from the neighboring wind farm, the same wind turbine model is used in all three wind farms.

The wake losses are calculated in the energy yield modeling in WindPRO. The wake decay constant is dependent on the turbulent intensity. A default value for closed farmland is selected. This will result in relatively small wake losses due the rather high turbulent intensities caused by the high roughness. The wake decay constant can be more accurately calculated when measurements of the turbulent intensities at the sites are available.

In addition to the energy losses due to wakes, a general loss is assumed for the three wind farms. The major contributors to the general losses are icing, turbulence, unavailability and 18

KVT/ALL/2013/R003 rev.1

electrical transmission. Losses due to high wind hysteresis and extreme wind speeds are expected to be minor contributors to the total general losses. For Storehei the general loss is estimated to be 13 %, the general loss is estimated to be 12 % for Oddeheia and Bjelkeberget.

6.1 Storehei

The layout at Storehei consists of 29 turbines and is shown in Figure 4-2. The mean wind speed at hub height for the layout is 7.8 m/s. The calculations for the expected annual energy yield are summarized in Table 6-2.

The three wind farms are located close to each other. The distance between center park of Storehei and Oddeheia is approximately 7 km, and the distance between center park of Storehei and Bjelkeberget is approximately 6 km. The two other wind farms may therefore influence the wake losses in Storehei wind farm. The energy yield with and without the neighboring wind farms are summarized in Table 6-2. As seen in the Table 6-2 the wake losses are increasing due to influence of the neighboring wind farms. The reduction in net power production is small, approximately 0.2 % for the studied wind turbines. For Storehei the highest net production and the highest full load hours are achieved with the Siemens SWT-3.0–113 turbines. WindPRO printouts are given in Appendix D.

6.2 Oddeheia

The layout at Oddeheia consists of 11 turbines and is shown in Figure 4-4. The mean wind speed at hub height for the layout is 7.3 m/s. The calculations for the expected annual energy yield are summarized in Table 6-3.

As for Storehei the calculations are performed for the energy yield without and with the influence of the neighboring wind farms and are summarized in Table 6-3. The influence of the wind turbines in the neighboring wind farms gives higher wake losses. The net power production is reduced with approximately 1 % for the three wind turbines types studied. For Oddeheia the highest net production and the highest full load hours are achieved with the Siemens SWT-3.0–113 turbines. WindPRO printouts are given in Appendix D.

6.3 Bjelkberget

The layout at Bjelkberget consists of 18 turbines and is shown in Figure 4-6. The mean wind speed at hub height for the layout is 7.6 m/s. The calculations for the expected annual energy yield are summarized in Table 6-3.

As for Storehei the calculations are performed for the energy yield without and with the influence of the neighboring wind farms and are summarized in Table 6-4. The influence of the wind turbines in the neighboring wind farms gives higher wake losses. The net power production is reduced with approximately 1 % for the three wind turbine types studied.

7 Uncertainty A detailed uncertainty analysis is considered to be outside the scope of this study. In the following the uncertainty for the energy yield calculations will be discussed and the different major contributors to the uncertainty will be identified.

The uncertainty in the energy yield estimate will be due to both uncertainty in the estimate of the wind climate, the methodology for the energy yield calculations, and the estimate of the losses.

The wind climate is based on data from the meteorological meso-scale model WRF. The uncertainty in the long term corrected wind climate in the data set used for this analysis is calculated to be 12 % (Byrkjedal and Åkervik 2009). Use of model data will increase the uncertainty compared to use of measurements from the respective wind farms. There is also uncertainty related to the micro-scale modeling of the wind conditions. Another factor that will contribute to the overall uncertainty is the zero-displacement height. It has been assumed to be 5 m in all the three wind farms. The forest on the highest parts is sparse, this means that the zero-displacement height is not large and the uncertainty is therefore limited.

For the energy yield calculations a general loss of is accounted for in addition to the wake losses. A detailed study of expected losses for the wind turbines will decrease the uncertainty for the losses.

Another factor that will contribute to the total uncertainty of the energy yield calculations is the energy sensitivity of the wind farms. The energy sensitivity describes how much the energy yield changes due to a given change in the wind speed. For sites with mean wind speed in the same range as the ones calculated for these wind farms the energy sensitivity is relatively high, contributing to a high total uncertainty for the energy yield estimates.

Due to the factors described above the uncertainty of the energy yield estimates is expected to be about 30 %.

8 Summary Energy yield calculations for the three possible wind farm areas in Aust-Agder are presented in this report. The wind data used for the calculations are from the meso-scale model WRF. The mean wind speed in the wind farm at hub height 119 m is estimated to be 7.8 m/s for Storehei, 7.3 m/s for Oddeheia and 7.6 m/s for Bjelkeberget.

Because of the short distance between the wind farms, the neighboring parks will influence the energy production of the wind farms. The influence is increased wake loss. In addition to the wake losses a general loss is assumed. The general loss is estimated to 13 % for Storehei and 12 % for Oddeheia and Bjelkeberget. The energy yield calculations are summarized in Table 8-1.

Appendix A. WRF

The Weather Research and Forecast (WRF) model is a state-of-the-art meso-scale numerical weather prediction system, aiming at both operational forecasting and atmospheric research needs. A description of the modelling system can be found at the home page http://www.wrfmodel.org/. The model version used in this work is v3.2.1 described in Skamarock et al. 20081. Details about the modelling structure, numerical routines and physical packages available can be found in for example Klemp et al. (2000)2 and Michalakes et al. (2001)3. The development of the WRF-model is supported by a strong scientific and administrative community in U.S.A. The number of users is large and it is growing rapidly. In addition the code is accessible for the public. The most important input data are geographical data and meteorological data. The geographical data is from National Oceanic and Atmospheric Administration (NOAA). The data includes topography, surface data, albedo and vegetation. These parameters have high influence for the wind speed in the layers close to the ground. Global meteorological data with 1 degree resolution, available from the National Centres for Environmental Protection (NCEP) with 6 hours interval, is used as boundary data for the model. The data originates from the Final Global Data Assimilation System (FNL). FNL is an operational assimilation model that incorporates all available observation data globally, and uses this data to create a global analysis dataset, or a snapshot of the atmosphere, four times every day. The assimilation model incorporates data from several thousand ground based observation stations, vertical profiles from radiosondes, aircrafts, and satellites. See http://www.emc.ncep.noaa.gov/gmb/para/parabout.html for further description of the data. The global data analysis is based on observational data for the time-frames 00, 06, 12 and 18 UTC. Surface roughness and landuse have been updated from Landmäteriets GSD database in Sweden and from the N50 series from Kartverket in Norway. The model setup used for this analysis is shown in Figure A-1. The model has been set up with 4 km x 4 km horizontal resolution. The model is run with 32 layers in the vertical with four layers in the lower 200 m. We have used the Thompson microphysics scheme and the YSU scheme for boundary layer mixing. The simulation outputs hourly data starting from 01.01.2000 and updated to current date on a monthly basis.
