| Summary/Abstract |
The main objective of this study is to provide a systematic decision support framework based on a holistic simulation approach that allows systematically the technical and economic analysis of a wind power plant (WPP). This model-based spread-sheet consists of various economic and technical indicators, including from the Weibull parameters to the cost of electricity generation. Various scenario-based analyses, namely WPP-1, WPP-2, and WPP-3, with wind turbines with different rated power are conducted for the proposed WPP. In this study, the capacity factor fluctuates from 25.62% to 30.03% while the annual electricity generation is in the range from a minimum of 22.449 MW and a maximum of 26.837 MW. Regarding economic indicators, the Internal Rate of Return (IRR) and the Levelized Cost of Electricity (LCOE) range from 11.7% to 17.38% and from 0.0665 €/kWh to 0.0771 €/kWh, respectively. By discussed and compared both economic and technical indicators, the most feasible scenario selection phase, which is the focal point of the study, is realized to construct and operate the proposed WPP. The developed simulation may be applied to other countries as well and in this way, it helps to be shaped strategic energy policies related to wind energy.

| Summary/Abstract |
Today's portfolio of energy production, based mostly on fossil fuels, and increasing energy consumption go against a sustainable vision for the world's development. Governments are shifting their energy policies towards renewable, nonpollutant sources of energy, developing large investment plans to ensure an adequate response to energy demand growth while keeping the environmental impact within reasonable boundaries. As in many other infrastructure-related sectors, new models for the provision of these facilities, and services, are being developed. Over the past 20 years, highways, hospitals, social housing, airports and dams have been developed in close collaboration with the private sector, not only in a contractor-supplier relation but also in deeper partnerships where the private sector assumes a substantial responsibility in managing and running the business. These models are known as public-private partnerships (PPPs). This research will look at the Portuguese experience in the application of PPP arrangements in the energy sector, particularly as far as the development of wind power plants is concerned. The evaluation procedures for selecting the private partner, the contract structure and the risk-sharing agreement are some of the issues deserving special attention.
