Estudo de viabilidade para instalação de um Parque eólico de 60MW em Maputo

Abstract

The present Bachelor's thesis proposes an analysis of the feasibility of installing a 60MW wind farm in Maputo, considering three study areas (Namaacha, Matutuine, and Manhiça) for the evaluation of the wind resource. Temporal variations in wind speed and terrain characteristics were carefully examined. With a notable capacity factor of 40,5% and an annual average wind speed of 7,66m/s, Matutuine stood out as the most promising area for the wind farm installation. The export capacity reached 211 .911 .828MWh, generating an estimated annual revenue of 20.343.535,50USD. With a Net Present Value (NPV) assessed at 43.423.948,60USD, the project proved financially attractive, and the payback time for the initial investment is projected to occur in approximately 7,6 years of operation, a period shorter than the project's lifespan of 20 years. In addition to the economic benefits, the installation of the wind farm in Matutuine anticipates an estimated annual reduction of 161 .773,4896 tCO2 in Greenhouse Gas (GHG) emissions compared to generating an equivalent amount of energy from natural gas. This reduction is equivalent to 376.217,42 barrels of oil not used. The thesis is structured into three main parts: Art Review, focusing on the historical context and principles of wind energy generation; Wind Resource Analysis and Implementation; and Economic Feasibility and Environmental Impact Analysis. Data from the Global Wind Atlas and NASA were used for the wind resource study, while simulations and economic analyses were conducted using the RETScreen Expert software.
