14 Abstract Jordan has a lack of conventional energy resources so it relies on neighboring countries in order to meet its demands. In concrete, resources such as crude oil, natural gas, and electricity must be imported. However, it is rich in renewable energy resources. Specifically, the most important and an attractive option, is the use of wind as a source of energy. In fact, Jordan has a very good wind potential, which can meet the growing energy demand. Five sites were selected in different regions of Jordan (north-hofa, north-ibrahimya, middle-tafila, middle-fujaij, and south-aqaba). Measurements by the National Energy Research Centre (NERC) where collected for many years, these measurements were evaluated in order to have an overview about the potential of wind resources in Jordan and to compare the different potentials for these sites. Those measurements were raw data of the average wind speed and wind direction. A wind farm was designed in each of the selected site by using the Wind PRO software and then technical and financial assessments were carried out. Those assessments have proved that the wind energy project can be a successfully project in Jordan and they are very attractive to investors. The Aqaba wind farm has shown that it is the best when compared with the other selected sites while the Tafila wind farm is in second place. Those two sites are likely the most promising sites to continue achieving the target of supplying Jordan with cheap and reliable energy. Also, they compensate each other depending on the season. Moreover, the two scenarios are suggested to achieve the Jordanian target 1000MW of wind energy by 2020 according to this thesis results. XIV

15 Chapter 1: Introduction 1

16 1. Introduction Wind Energy is one of the most promising sources for renewable energy in Jordan. There are many sites which have a good wind potential. This thesis looks at technical and financial aspects of wind farm installation for many sites, and it provides comparison and evaluation for different wind development regions, which gives the overall picture about the wind potential, grid capacity, energy consumption and needed infrastructure for installing wind farms for many areas in Jordan. The Wind PRO Software has been used to analyze the real measurements masts for the wind speed and wind directions and to predict the energy yield, capacity factors, and wind farms layouts for the selected sites. In the second chapter the Energy Sector, Electricity Sector, Wind projects, and Renewable Energy Law in Jordan will be introduced. In this chapter it will be revealed the several parameters which are affecting the wind projects and investors who want to enter the Jordanian energy market. It also gives an indication about the whole Jordanian situation regarding renewable energy, especially wind energy since wind energy is one of the cheapest available renewable energy sources. The following chapter will be about the technical assessment of wind regimes in different regions in Jordan. It will cover many technical aspects such as the wind potential in Jordan, national grid transmission lines, sites selection, wind turbines selection, analyzing raw data from real measurements masts, and designing five wind farms in different sites. The calculations are carried out for (CF) capacity factor, (AEP) annual energy production, array losses, average wind speed, wind direction roses, and the final wind farms layouts. In addition, the fourth chapter will be about the financial assessment of potential wind energy projects for the selected sites in Jordan. It will cover many financial aspects such as the payback period, net present value, internal rate of return, return on investment, levelized cost, and sensitivity analysis. In addition, the fifth chapter will be about the comparison between the selected sites from technical and financial viewpoints. Also it will explain briefly how the wind regime is different from site to site on an hourly and monthly basis. Finally, the sixth chapter will recommend the scenarios to achieve the Jordanian target of wind energy. This chapter will suggest the two scenarios to reach the Jordanian target 1000MW of wind energy by

18 2. Overview for Energy Situation and Wind Energy in Jordan 2.1 Energy Sector in Jordan Status of Energy Sector In order to better understand the current status and the planned future of the energy sector in Jordan, it is important to present some introductory geographic and demographic as well as economic information about the country besides some statistics of the energy consumption from various sectors over the last ten years. Jordan is located in the Middle East. Situated between the longitudes 35 o and 39 o E and between the latitudes 29 o and 33 o N with a total area of 92,300 km 2. 90% of this area is classified as desert. Considering the past ten years, i.e , the population has increased from 4,900,000 up to 5,980,000 with an average annual growth rate of approximately 2.5% [1]. Jordan is classified by the World Bank as a "lower middle income country". The nominal Gross Domestic Product (GDP) for 2009 was $ billion ($3,828 per capita) achieving an annual growth rate of 3.2%. According to the Department of Statistics, almost 13% of the economically active Jordanian population residing in Jordan was unemployed in The currency has been stable with an exchange rate fixed to the U.S. dollar since 1995 at JD to the dollar [1]. This continuous growth of population and economy has been accompanied with an increase in the energy consumption as can be seen in table (2.1) which demonstrates of the behavior of energy demands with the variation of population and economic indicators. 4

The consumption has risen from 5114 up to 7739million Ton Oil Equivalent (TOE) as illustrated in figure (2.1) which was plotted according to the data available from the Ministry of Energy and Mineral Resources [2]. Most of the final energy (39%) is consumed by the transportation sector while the industrial and residential sectors equally consume 22%. The rest of final energy is consumed by commercial buildings and public services such as water pumping and street lighting. the energy consumption by various sector is shown in figure (2.2). 5
