RET Screen Assessment of Utility Scale Wind Power Generation Based on Historical Wind Speed Data-the Case of Mankoadze in the Central Region of Ghana
並列摘要
With cost being a vital factor for determining how feasible any power project will be, this study demonstrates that a 50 MW grid-connected wind power plant at Mankoadze in the Central Region of Ghana will be technically and financially viable and competitive at a certain minimum feed-in-tariff together with some incentives. In this study, we analyzed monthly mean wind speed data for Mankoadze at 12 m above ground level (a.g.l.) with RET Screen Wind Energy Project Model. The monthly mean wind speeds at 12 m a.g.l. were extrapolated to 80 m a.g.l. and used to determine the annual energy production of a 50 MW wind farm. The total initial cost of the 50 MW wind power project was estimated and the minimum feed-in-tariff at which the project will be financially viable over a duration of 20 years was ascertained from Net Present Value (NPV) calculations. This minimum feedin- tariff was again determined for different scenarios of grants and incentives and some recommendations were made.
