The height above sea level of the wind farm varies from 2,000m to 2,131m and its central coordination is between the north latitude of 41°05’ and the east longitude of 112°41’ . The wind farm is 120km west to Huhhot, the capital city of Inner Mongolia Autonomous Region and 60km east to Jining, where the municipal government of Wulanchabu city is located. Huitengxile wind farm is in Huitengliang area, which is in the east part of Daqingshan Mountains. It belongs to continental monsoon climate. The main weather affection of this area is the cyclone from the bend of the Yellow River and the cold high pressure from Siberia and Mongolia Plateau. Affected by the strong cold pressure, this area becomes the main path when the cold air flows down from north to south. The natural characteristics of this area such as the high altitude, open terrain, low vegetation, fewer buildings, and the affection when air flows through the raised tableland from north to south, etc., make it possible that the wind energy resource is very rich here, it is one of the richest wind energy resource areas in China. 1.2 Brief introduction of the project Huitengxile wind farm with total planned capacity of 200MW was primarily built in 1996. By the end of 2003, the total installed capacity in this wind farm is 42.7 MW, among which 5.4MW(9 sets with 600kW each) wind turbines are financially supported by Danish government; 19.8MW(33 sets with 600kW each) wind turbines are under the project of “double Promotion” sponsored by Chinese government; 5.4MW(9 sets with 600kW each) wind turbines are under the financial assistant by Dutch government, 5.5MW(10 sets with 550 kW each) wind turbines are supported by the US import & export Bank loan, 5.4MW(9 sets with 600kW each) wind turbines are supported by Germany government; and 2 test sets with 600kW each erected by Micon A/S Page 5 2 and Beijing Wandian Company. At present, there is one substation (110kV, Caoduoshan substation) in the wind farm, with the capacity of 76 MVA(1Χ16+1Χ20+1Χ40), and the voltage is 110/35/10kV. The generation of the wind turbines feed in the west main electricity network of Inner Mongolia by the 110kV transmission line to the 110kV bus of Gaoshun 220kV Substation. This project is a technical reformation project as well as the commercialization promotion project of China renewable energy program supported by GEF and the World Bank. The scale of this phase is 100MW (with the wind turbines of 750kW-1500kW each). Referring to the existing experiences of designing and building, the row space is 7 D and the column is 5 D, meanwhile, an auxiliary transmission line to Desheng 220kV substation and one 110kV substation (2Χ630MVA) will be built. 1.3 Features of the region 1.3.1 The terrain Huitengxile wind farm region is tableland grassland with an area of about 300km 2 . The occupied area of Huitengxile wind farm is about 100km 2 . The terrain of the wind farm is flat with few buildings and low vegetation, and it has more than ten lakes with different sizes. The altitude varies from 2,000m to 2,130m. Most part of the wind farm is meadow, grazing or open land with few trees. The geological structure of the wind farm belongs to intermountain lava tableland with no structure affection, it has fine stability and no rift passes through. Location of this project is in the southeast of the existing wind farm, which is along with the ke-zhuo road at the site of 18.5km-21.5km. The total size of this phase will be 22km 2 of flat and open land with no buildings. Huitengliang area is typical mountainous grassland. The soil is chernozem; the vegetation are mainly gamineous grass with little linear-leaf chrysanthemum, garden burnet, artemisia, wind-weed and Chinese thorowax etc.; the birds are mainly rock partridge, quail, partridge with spotted wings, turtledove, lark and tree sparrow. 1.3.2 Wind energy resources Page 6 3 Huitengxile region belongs to temperate zone continental monsoon climate; the main affecting systems of climate in this area are cyclone from the bend of the Yellow River and the cold high pressure from Siberia and Mongolia Plateau. The cyclone from the bend of the Yellow River mainly affects the precipitation of the middle and west Inner Mongolia, the precipitation in this region generally concentrates in summer, little rain and large variability are the main features. The most serious influence to the area is the high cold pressure from Mongolia plateau, especially in December and January. It has long cold winter and short cool summer, and the wind speed is high in winter and spring, the mean annual wind speed at the height of 10 meters is 7.2m/s, about 70~80 days the instantaneous wind speed is more than 17m/s. Controlled by the strong Mongolia cold high pressure, Huitengxile area has become the main path for the cold air. The altitude of the site is relatively high, so it has increasing effect as the air stream passes through this area from north down to the south. Furthermore, the area is open and flat with low vegetation and few buildings and trees and small frictional resistance, it is windy all the year round, especially higher in winter and spring, so the wind energy resource is very rich. (1) Measurement method In order to develop and utilize wind energy resource, the former Inner Mongolia Electricity Company had erected 10 measuring towers (40m high) in the middle area of 100km 2 in December 1993 and had performed measurement from March 1994 to February 1995. After that, the work was suspended due to some reasons. In October 1997, Inner Mongolia Longyuan Wind Energy Developing Cooperation restarted the measuring work in Huitengxile wind farm. 4 measurement towers (40m high) were erected and 8 sets of EL anemometers were installed. In addition, a basic meteorological station was built. Since then, the measuring work has been performed continuously for 6 years. Based on the analysis of wind data collected from anemometers, the average wind speed at the height of 40m is 8.4 m/s in the past 6 years, and the average wind power density is 500W/m 2 . The yearly average wind speed is steady and the variation range is 8.0~8.9m/s, but the average wind speed in Page 7 4 every month of one year varies, the wind speed in January, February and March is relatively high, and the variation range is 9.9~11.3m/s; the wind speed during June to September is relatively low and the variation range is 5.9~6.6m/s. (2) Distribution of wind speed and wind energy The 40m high distribution statistics of wind speed and wind energy frequency of the wind farm show that the wind speed multi-values appear at the range of 4~10m/s, accounting for about 71% of annual wind speed distribution; the wind energy multi-values appear at the range of 10~16m/s , accounting for 69% of total wind energy distribution. The 10m high distribution statistics of wind speed and wind energy frequency show that the wind speed multi-values appear at the range of 4~8m/s, accounting for about 71% of the annual wind speed; the wind energy frequency multi-values appear at the range of 8~12m/s, accounting for 64% of total wind energy distribution. (3) Wind energy direction From the statistics and analysis of the wind energy frequency data measured by the 40m high anemometers during 1998~2003 , the wind energy is mainly concentrated at 225~335 °. According to the statistics of a typical year (2001), the wind energy concentrated at 225~335°accounts for 70% of the total wind energy. The statistics and analysis of wind direction and wind energy frequency at the height of 10m in 2001 show that the wind energy is mainly concentrated at 225° 335° , accounting for 72% of the total wind energy and it is almost identical with the wind energy frequency distribution at 40m high. From the above analysis we can see that the wind direction of the area is stable and the wind energy is concentrative. 1.3.3 Transportation Huitengxile wind-farm is 120km east to Huhhot, the capital city of Inner Mongolia Autonomous Region, 60km west to Jining, and 36km south to Zhuozishan railway station. The Ke -Zhuo road goes through the middle part of the wind farm and connects to the110 national highway in the south. So the large wind turbines can be directly transported to the wind farm. Page 8 5 The ground of the wind farm is flat, and the existing natural road can be used for transportation during the installation period and the maintenance work after the wind turbines put into operation. Equipments can be directly transported to their locations without second transportation or manual carrying. 1.4 Social and economic situation 1.4.1 Social and economic situation of Inner Mongolia Autonomous Region Inner Mongolia Autonomous Region is located in the north border of the People’s Republic of China. It is long and narrow from the northeast to southwest. The terrain is mainly plateau so it is normally called Inner Mongolia plateau. The area of the region is 1.18 million km 2 with the population of about 20 million, as it is an autonomous region with multi-nationalities, Mongolia nationality is the main part. Inner Mongolia has a vast territory and rich resources, and it is commonly known as “Forest in the east and iron in the west, agriculture in the south and animal husbandry in the north, coal are everywhere”. The total grassland in the region reaches 0.88 million km 2 and it is an important animal husbandry base in China. Hetao and Tumochuan plains are famous grain producing bases in China. The industry enterprises in Inner Mongolia are mainly engaged in iron steel, coal, electric power, metallurgy, textile, chemistry, leather and brewery etc. By the end of 2002, the GDP of the region reached 173.248 billion yuan RMB, compared with the last year, 12.1% was increased; the grain production reached 1.41million tons and 13.5% was increased compared with the last year; the raw coal production reached 114.9763 million tons and 40% was increased compared with the last year; the electricity power generation reached 54.726 billion kWh and 17.6% was increased compared with the last year. 1.4.2 Social and economic situation of Wulanchabu city Wulanchabu city is located in the middle of Inner Mongolia Autonomous Region with an area of 84000km 2 . The total population is 3.16 million, including more than 20 nationalities. Wulanchabu city belongs to northern dry land crops area, the total cultivated area is 13400 km 2 . Crops here are mainly wheat, naked oats and Page 9 6 potato. The grass resources for animal husbandry in the area are relatively rich. It is a famous natural pastureland in Inner Mongolia and the total area of the grassland is 58000 km 2 . It is also an important meat production base in Inner Mongolia. Industrial enterprises in Wulanchabu city have expended to a certain scale. Enterprises of electricity, metallurgy, machinery, coal, construction materials, fertilizer, fresh processing, sugaring and brewing have already been founded, and mineral resources are also rich, more than 70 minerals have been discovered and 25 minerals have been utilized by now. Referring to the transportation, the railway from Beijing to Baotou city goes through the middle part of the area; the Ji-Er railroad is start from Jining, the location of the administrative offices of Wulanchabu city, to Erlianhot, an important land port city in north China and connects to the railway of Republic of Mongolia; in addition, Ji-Tong railroad is associated with five more railroads in Tongliao. The road network has been formed, which is centered in Jining, and the 110 national road is the main vehicular truck line, reaching various counties and towns attached to Wulanchabu city and the adjoin areas. 1.4.3 Social and economic situation of Huitengxile wind farm area The wind farm is located in the middle of Chayouzhongqi, with an area of 300 km 2 . Chayouzhongqi belongs to half agriculture and half animal husbandry area. The main corps is wheat and potatoes, and the total corps production in 2000 was about 154 million kg. Animal husbandry is mainly sheep, horses and cattle. The total amount of livestock on hand in 2000 was 708 thousand. The average income in this area in 2000 was 3,385 yuan and 1,828 yuan was the net income of farmers and herdsmen. 1.5 Land used The 100 MW technical reformation phase in Huitengxile wind farm will be carried out on the grassland of Huitengliang farm, neither the land of other villages nor the farmland will be occupied. Huitengliang farm was founded in 1953. It is a state-owned stud and the land is also state-owned. Its function is mainly keeping stud horses and breeding and developing Inner Mongolia fine-wool sheep. The total area of the farm is 4800hm 2 , and the area of grassland is 4300hm 2 , among which the high Page 10 7 quality meadow is more than 670hm 2 , the forage grass land is 170hm 2 , the area of covered pen is 6,615 m 2 , the area of living quarters for staff and workers is 3,554 m 2 and the area of other infrastructure is 3,911 m 2 . There are 332 employees in the farm, including 120 workers, 5 administrative management personnel, 6 studhorse feeding and managing stuffs, 6 technical staffs, 74 fine- wool sheep feeding and managing stuffs, 30 teachers and service stuffs and 16 retired persons. The current management mode is that the farm contract studhorses, fine-wool sheep and fodder land to staffs, but excluding the meadow, the meadow is used by all. There are also infrastructures in the farm such as administrative office, livestock veterinary station, guesthouse, canteen, living quarters, covered pen, ammonia ion stove and grass storage yard. Based on the animal husbandry production, the annual total income is about 0.6 million yuan and the average income per capita is more than 3,000 yuan. Currently, the meadow area in Huitengliang farm is about 4300hm 2 , the permanent occupied land of this project is about 23.65hm 2 , accounting for 0.55% of the meadow area. Very small impact on animal husbandry production will be produced. At the construction time, some temporary land will be occupied for one or two years, plus the recovering time, 3 years will be enough, and the land will be returned to Huitengliang farm after construction. Moreover, during construction period, the region and meadow will be occupied as planned strictly, so it will have few impacts on the production and living conditions of local villagers. 2 Summary of Environmental Impact 2.1 Ecology status The Huitengxile wind farm is located on Huitengliang ridge in the middle part of Wulanchabu city, Inner Mongolia. This area is typical mountainous meadow grassland, the soil is chernozem, the vegetation is mainly graminence pasture with less chrysonthemum, artemisia, rhizoma anemarrheae and radix bupleuri etc. and there are some kinds of bird like rock partridge, quail, partridge, turtledove, lark and tree sparrow etc. 2.1.1 Potential impact on birds during construction period Page 11 8 Construction period mainly refers to the time of foundations construction, wind turbines installation, meteorological observation tower setting up, roads repairing inside the wind-farm and other facilities. The typical potential impacts that will disturb the original living environment of birds should be the noise, dust and transportation vehicles etc., and the birds inside the wind-farm will not be able to seek food, build their nest and breed here. Since the construction period is short, comparing with the whole area, the occupied land is small. In addition, the birds have the ability to avoid danger and they can migrate to other places where the conditions is the same, therefore, the construction will neither produce serious impact nor cause the reduction of birds. 2.1.2 Potential impact on migratory birds According to the collected bird ring-mark information, Huitengxile wind- farm area is neither the main habitat for migrant nor the main path passed by migrant birds, so the construction of the wind-farm has almost no impact on migrant birds. From available information, the flying height of most birds is around 300 meters, but the hub height of the chosen wind turbine in this phase will be no more than 100 meters. The average flying height for migrant birds is much higher than 100 meters, so it is impossible for migratory birds to collide wind turbine when they fly through this area. For this reason, there is no impact on migratory birds after the wind turbines put into operation. 2.1.3 Potential impact on Birds’ colliding with wind turbines Flying birds within the wind farm may collide with the blades of wind turbines, electric transmission line and meteorological measuring towers. Some big size or heavy birds, water birds, some birds of prey catching other birds and the birds flying in low level in night are apt to collide with wind turbines. The birds’ data of Huitengliang area show that most birds mentioned above are not seen often, so the chance for birds colliding with wind turbines is few, which means that the wind turbines will have little impact on these birds. Other common birds are small in size and fly agilely. In addition, wind turbines are so obvious that the birds can see it clearly and avoid it. It has little chance for these birds to collide with the wind turbines. Therefore, the construction of the wind farm will have little impact on birds in the area. So far there haven’t been Page 12 9 any studies on the impact of the existing wind farm on the birds. According to a ten-year investigation on this wind farm, there hasn ’t been any crash accidents occurred. 2.2 Impact on natural landscape In this project, some wind turbines (from 750kW to1500 kW each) will be erected in the southeast side of the existing wind-farm. The local residents believe that so many wind turbines standing upright on the grassland will not destroy the local natural landscape. However, it will form beautiful and attractive scenery. In the vast grassland, a lot of white wind turbines stand in order and rotate in the blue sky, the white cloud and green grassland. In fact, since the primary construction was completed, the tourism site had been built by the relevant department. The local tourism resource is developed and considerable tourism revenue is gained. As the expanding of the wind farm, the number of wind turbines will grow and the scenery will be surely more beautiful. For this reason, this phase of Huitengxile wind farm will have no impact on the local scenery; on the contrary, it will raise the local scenery value and increase tourism revenue. 2.3 Potential impact on electromagnetic radiation 2.3.1 Impact on electromagnetic radiation to the health of local residents A special study shows that when electromagnetic radiation with or beyond the intensity of 4kv/m acts on a healthy people for a long time, he will be damaged. Electromagnetic radiation with certain energy will be produced during operation of the wind farm, but its intensity is relatively low. Although there hasn’t been a practical value for relatively low intensity electromagnetic radiation, it is can be deduced from the available test data of 220kv. The maximum intensity of 110kv/m is 0.287kv/m, which occupies 7.2 percent of the standard intensity 4kv/m. In addition, the wind farm is far from residential area, so it is believed that the electromagnetic radiation produced by Huitengxile wind farm will not create hazard to the health of residents nearby. 2.3.2 Disturbance of electromagnetic radiation to radio and television Page 13 10 We learnt from the investigation of residents who live near the wind farm that the wind farm operation currently has no influence on local radio and television etc; therefore, it is believed that this phase will not produce disturbance to local radio and television. 2.4 Impact on Noise 2.4.1 Noise impact on the surrounding environment Since the specialty that the wind farm must be built in the place with rich wind energy resource and wind turbines must operate in some higher wind speed, the noise of the site is relatively large. When wind speed is high, the natural noise covers up the noise of wind turbines, and the noise impact produced by wind turbines on the surrounding environment is far less than the noise produced by natural wind; when wind speed is relatively low, noise produced by the wind turbines will attenuate rapidly. According to practical measuring results in Zhangbei wind farm, the environment noise in the place of 250m far from wind turbines is 39.5 dB (A) which is lower than the limit of class one urban environment noise standard (55 dB (A) in daytime and 45 dB (A) in the night). Therefore, the operation of wind turbines almost cannot produce noise impact on surrounding environment. This may be true for one unit, or maybe for all of the units currently in place. However, the proposed phase will have 750kW to 1500kW wind turbines which are larger than the existing wind turbines (72 sets and the largest is 600kW). So it is not immediately obvious that noise will not be a problem. Since the 1500kW wind turbines haven ’t been put into operation, it is not available to predict and analogize the results. 2.4.2 Noise impact on the staff According to the data provided by wind turbines manufacturers, the largest noise level is about 90 dB (A). Since the operation work in the wind farm is totally finished by computers, normally the operation staffs will work in the control room. It is no need for them to work near the wind turbines. In addition, the control room is quite far from wind turbines, the noise of wind turbines cannot affect the health of operators. As for those who must do repairing and maintenance job, normally the wind turbines must be shut down, Page 14 11 and the working period is short, so it is believed that the noise of wind farm have no impact on the health of operation staffs. 2.5 Reasonable arrangement of the transmission line Huitengxile wind farm is far from residential area and the power transmission lines are not in residential area either, they go through the desolate and uninhabited tableland. The existing substation (110kV, Caoduoshan substation) with the capacity of 76MVA(1Χ16+1Χ20+1Χ40) is 110/35/10kV. A 15km 110kV transmission line to the 110kV bus of 220kV Gaoshun Substation will be erected so that the power generation of the wind turbines will feed in the west main electricity network of Inner Mongolia. It will go 1.5km over to the west of the existing 110kV line from the wind farm, and then parallel to the existing Gaoshun-Desheng 220kV line to the Desheng substation in the north (see the drawing for detail). The distance between the two lines will be 30m. The rated voltage grade of the new line will be 110kV, the type of the cable will take LGJ-400/35. There will erect 49 towers for the line, the foundations of the line towers will occupy 250m 2 ,which is neither cultivated land nor residential area, and the height of the towers will be 27-30m. The arrangement of the power transmission lines is reasonable and in accordance with the design, it will have no impact on the producing and living condition of the residents. The design of power transmission line follows the design criterion for substation, the distance to the ground will meet the design specifications, so it will be safe as pedestrian or sheep pass by under the transmission lines. 2.6 Impact during construction period (1) In order to protect meadow, the soil from foundation will be moved away manually; stones will be loosened by explosion first and then moved away manually, the residents nearby will be announced two days before the explosion. (2) At wind turbines assembling site, all the facilities will be put in place as designed so as to control the occupied area and protect the meadow effectively. (3) It has been issued that all vehicles must run on the specified roads and mustn’t run in grassland randomly in order to protect meadow during the construction period. Page 15 12 (4) 50% of spoil produced during construction will be backfilled into the foundations and the other 50% will be backfilled into adjacent gully. (5) After the construction, both sides of the road especially for repairing and maintenance in the wind farm will be made green in order to reduce the desertification of the area. Detailed regulations during the construction and operation see table 5.1-1 3 Other Condition Two villages, Hongpan and Caoduoshan, are near Huitengxile wind farm. Hongpan is located 3km north to the wind form. There live 261 people in the village and they are all Han nationality. The village occupies 80km 2 in which 13km 2 are farmland and crops are mainly barley and oil crops. Caoduoshan is located 2.5km northwest to the wind farm. There live 182 people in the village and they are all Han nationality. The village occupies 52km 2 in which 9.3km 2 are farmland and crops are mainly barley and oil crops. 4 Benefit Analysis 4.1 Social and environmental benefit A 100MW coal-fired power plant runs 2,440 hours per year will produce 826 tons of smoke, 1,900 tons of SO 2 and 11000 tons of rejects. It also needs a large quantity of water, and about 60~80 dB (A) noise will be produced due to factors like exhaustion, mechanical rotating friction and electromagnetic. The power generation process of wind turbines is to transform the local wind energy into mechanical energy, then to electricity energy. This will not produce pollution of air, liquid, solid contaminants or produce serious sound pollution during the whole process. The wind farm will be one of the best replacements of coal-fired power plant, for it utilizes natural renewable resources, and it will greatly reduce pollution to the surrounding environment, save normal fossil energy, protect ecological environment. Page 16 13 4.2 Coal saving and electric power increasing A 100MW coal-fired power plant consumes 115 thousand tons of standard coal. This big number can be saved by utilizing wind energy resource, meanwhile 405,408MWh green power generation will be increased in the power network and good economic returns will be gained. 5 Environment Management plan 5.1 Environment relief plan The possible impacts on the environment and the environment relief methods are listed in the following schedule.

All of the investigated people think that the meadow should be protected and the environmental sanitation should be taken care of during construction period, the local residents should be temporarily employed if necessary. In general, most residents here are careful about and support the project. They also expressed their own opinions on the potential environment impacts that maybe occur during the construction of the project. We have paid attention to them, and effective measures will be taken in the design of the project. 6 Conclusions The project will select advanced equipments, so the pollutants such as air, liquid or solid wastes will not be produced during the wind power generation, serious electromagnetic interference and sound pollution will not be produced too, so there will be little negative impact on the environment. Furthermore, the wind farm can produce clean and green energy which can replace coal-fired power, greatly reduce pollution of the environment, utilize natural re-generable resources and save non-recoverable fossil fuel resources. Great environment and social results can be achieved from the project, so it is practicable in the view of environmental protection. Page 26 23 Page 27 24 the red one is the new line Page 28 25
