SUMMARY:

The consumption of electric energy produced from renewable sources grows every year and the development of new technologies has reduced the cost of generating this type of energy attracting the attention of investors and governments. By the year 2050, 86% of all electricity is expected to come from renewable sources. In this scenario, wind power stands out due to its high electricity generation capacity and the investments received in recent years. Considering a project for an offshore wind farm, investments may exceed the 1 billion dollar value. Due to the high investment required and the complexity of developing a project of this nature, it is necessary for investors to know in detail the risks of this project and the returns that can be obtained, mainly, in financial terms. This research aims to propose a framework of a specialist system for economic analysis on the life cycle of offshore wind farms. Was developed in four phases: theoretical foundation and the state of the art (1st phase); formulation of the conceptual model (2nd phase); validation of the conceptual model (3rd phase); modelling of the specialist system framework (4th phase). In the 1st phase, 47 articles were analyzed during the Systematic Bibliographic Review, in addition to theses, dissertations and technical reports on the theme. The 2nd phase included the systematization of the variables identified in the previous phase and the structuring of the conceptual model, considering the life cycle of an offshore wind project. The framework formulated is divided into three macrophases: Pre-Development; Development and Operation; and Post-Operation. In the 3rd phase, the conceptual model was validated with specialists from the offshore wind sector in two moments: 1st - application of the questionnaire with specialists from the offshore wind sector who work in the European market to validate the variables that should be considered in the sensitivity analysis of the project ; and 2nd - application of Focus Group with experts from the wind sector that operate in the Brazilian market. The considerations of the experts were used to propose the framework of the expert system (4th phase). The framework is divided into 5 modules: Pre-Development Module; Development and Operation Module; Post-Operation Module; Transversal Costs Module; Recipes module. The modules consider the costs, revenues and financial expenses of the project that are integrated in a cash flow, allowing to obtain economic indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), Simple Payback, Discounted Payback, Levelized Cost of Energy (LCOE), CAPEX/MW, OPEX/MW and DECEX/MW.
