**4. Case Study**

The installation and maintenance maneuvers defined in Section 2, along with the economic-financial methodology shown in Section 3, will now be applied to a case study consisting of a 50 MW TEF. This farm is composed of gravity-based first generation TECs and is located in the Alderney Race, which is one of the Channel Island Races in the United Kingdom (UK). This will be done in order to determine the viability and profitability of the project from the economic-financial point of view, when using either manual or automated maneuvers, together with the realization of a sensitivity analysis. The analysis will be carried out in an attempt to show that automating these maneuvers will improve the future competitiveness of tidal systems. It may also allow us to detect business risks in the case of the oscillation of fundamental variables of the model, such as investment, the annual energy production, the price of energy, the interest rate, the percentage of loan requested or the tax rate. We shall deal with all of the aforementioned aspects below.
