CoST Of Wind

• Large-scale offshore wind farms are getting more popular due to better wind conditions on the open sea. Several methods exist to connect offshore wind farms to the main electricity grid. In this paper a tool for estimating the overall connection costs for the link between the main grid and a wind farm is shown. The method compares both AC and DC connection options. In order to estimate the overall costs, several technical input parameters such as the transmitted power, the voltage level, connection requirements, etc. must be taken into consideration. Besides the technical aspects several non-technical aspects such as connection distance and prices for the used equipment have to be taken into account. Also the maintenance costs and costs for transmission losses as well as the energy that is delivered to the grid must be considered to get a realistic picture of the overall costs for different connection methods. This paper shows how these overall costs can be estimated and how a cost effective investment can be made. The described methods are implemented in an easy to use tool, which can be used by any project developer to get reasonable first estimate of the costs. The method is developed in Microsoft Excel (R).
