Abstract

FEASIBILITY ANALYSIS OF DEVELOPING WIND POWER PROJECT IN IRAN

Introduction

Wind power projects is become one of the most interesting field of renewable sources in Developing countries. Iran ( as developing country) start to develop wind power project regularly. creation of new market in the field of wind energy will be an interesting issue for European developers and investors. Iran, already install several wind turbine from European manufacturers and it has several high wind location to install onshore wind farm.


Approach

According to the importance of financial factor in developing wind power projects this paper provides useful information for European developers. accordingly, all wind data information gathered from 80 meter met.mast with cup anemometer and wind data analysis and filtered by different software such as windograf then wind turbine selected from European manufactures the wind farm analysis done by WindSim and energy map created from final results the best wind farm optimization done by windpro and windSim and the best array selected correspondingly. All financial data gathered from real construction project such as number of labor, wages, transportation cost, installation costs, cable costs and etc. The time table and related Gantt chart created for this project based on estimation of installation schedule of the same wind farm in Iran
The final approach in this paper is to introduce Iran as an interesting country for developing wind power project based on production capacity factor of installed wind turbine and also considerable cost reduction due to microeconomics of Iran such as inflation and exchange rate of Euro.
Considering Feed in Tariff system and other financial supports such as grants and rebates guaranteed by the latest governmental decision in the field of renewable energy specially wind power, Iran can be an interesting play-field for wind power developers specially European companies.
This paper illustrate the strengths of developing wind power project in Iran by European wind turbine and come up with and financial benefits for developer or investors who wants to participate in this progress.

Main body of abstract

According to global growth of wind power and recent attempt to develop wind power in Middle East, Iran makes a considerable effort in this field. Accordingly, wind atlas map of Iran is prepared by RenewableOrganization of Iran (SUNA) and consequently, high wind regions recognized. The maps are available in two different altitudes of 40 and 80 meter. Recently, new guidance of Feed in Tariff (FIT) system revealed, and respectively private companies try to participate gradually in these projects by the new financial encouragement.
Undoubtedly, the most important factor to attract private companies is regarding economical issues such as Payback Period, IRR and etc. But the primary factor is based on technical calculation and analysis. This paper focused on feasibility of wind farm installation in IRAN, and demonstrates the progress process of wind power project, in this developing country. Moreover, it covers economical calculation to illustrate how European investor or developers can participate correspondingly. This work has been done by both technical and economical analysis via Windsim for 25 MW wind farm .
In this case, wind data gathered from various installed met.Mast and three different high wind location selected in south east, East and middle of Iran, considering infrastructure issues such as grid connection, Transportation, Transformers, and etc. The best location selected for this analysis.
Kohin wind farm is located in Qazvin province is selected as the best place, based on different infrastructure factors and high wind speed. The terrain is not complex and roughness class is low. Regarding wind data collection, we use three different met. Mast which are already installed at this locations.[Fig 1]
1- Asfestan met.Mast with three anemometers height at 10m, 20m and 40 m above the ground, wind data collected from 2002 to 2006 every 10 minutes.[Fig.2]
2- Nikooyeh met.Mast with three anemometers height at 10m, 30m and 40m, wind data collected from
Nov.2009 to Jun.2010 every 10 minutes.[ Fig.3]
3- Kohin met.Mast with three anemometers height at 40m, 60m and 80m, wind data collected from
May.2011 to May.2013 every 10 minutes.[Fig.4]
Considering wind data analysis via WindSim the best height for wind turbine hub is 80 meter at this location. [Fig.5]
Based on the experience of using Nordex wind turbine in Iran we come up with selecting 10 numbers of Nordex N90/2500 LS for 25 MW wind farm.
Finding the best place for wind turbines and wind farm arrays completely done by WindSim . In this case, we use Energy map, and also we consider feasibility of land acquisition such NIMBY and earthquake analysis. Then, WindSim puts WTG’s on the land with the best distance from each other regarding wake effect and the best reachable production. [Fig. 6] The total production is 77269.4 MWh/y with capacity factor of 35.28%.[Fig. 7]
The economical analysis done by available data from real project in Iran. All the cost and expenses are gathered from an under construction wind farm project. Turbine Cost, Transportation cost, installation cost, cable cost, labor costs and all other expenses are calculated with additional contingency factor.

The final economical result can demonstrate the rate of interest in investing in wind power section in Iran, and also the wind potential available at this location. [Fig 8]


Conclusion

As a conclusion this paper considers technical analysis to show wind resource and potential in Iran. Moreover, it covers a real financial analysis to show the benefits of developing wind power in IRAN. European companies with their mature technology can participate in developing wind power project in Iran, but they need to make sure about their investment in both Time and Money. Different financial policies strongly support developing wind power specialty for wind power developer, manufactures and investors in Iran. High wind Potentials and the best places identified for this development. Their payback period will considerably decrease by low tax services, Feed in Tariff system and other economical supports. Indeed, Koohin wind farm can be one of the conspicuous examples which can clarify all the aspect of developing wind farm in Iran. Its noticeable production and its Cp can encourage technical part and its FIT and Low taxes plus CDM can be an Icing on the cake for the developers and investors.
On the other hand, considering Environmental issues and reduction of green house gases, wind power project plays an important role in this field. Indeed, Iran is one the most important countries in exporting Oil and Gas and renewable energies just cover blow 1% of total consumption. Obviously, initiating wind power project with Collaboration of European companies and other support such as EWEA can be the most effective encouragement for other Energy company in Iran.
All in all, comparing different developing countries, Iran will be one of the most important countries in developing wind power in near future. Collaborating with advance European technology can ramp up this development rapidly.



Learning objectives
Developing wind power projects needs to expand globally. Developing countries such as Iran can be an interesting playing field for developers who want to widen their effort out of European borders. This paper presents the opportunity of developing these projects in Iran by European companies and provides a feasible example of “under construction” wind farm for calculation analysis. Companies will understand the method of participation in both Technical and Economical field in Iran.
