The operation of the platform will be based mainly on renewable energy technologies, such as photovoltaics and wind turbines. In order to utilize properly the renewable energy potential, the sea platform will also include batteries and diesel generator, whereas the option of grid interconnection with Crete Island is also examined, in order to purchase and sell its electricity when needed. The alternative options that are examined include different battery autonomy, various funding options, and sensitivity analysis of the results regarding different lending parameters. The financial indices used in this analysis are: net present value, internal rate of return, discounted payback period, and weighted average cost of capital. The results show that the operation of the sea platform can be economically viable if annual incomes of a few hundred thousand euros exist, provided by platforms research activities.This work received financial support from the project “Centre for the study and sustainable exploitation of Marine Biological Resources (CMBR)” financed by the General Secretariat for Research and Innovation under the Action “Reinforcement of the Research and Innovation Infrastructure”, funded by the Operational Programme “Competitiveness, Entrepreneurship and Innovation” (NSRF 2014–2020) and co-financed by Greece and the European Union (European Regional Development Fund).http://creativecommons.org/licenses/by/4.0/425–4382021 International Conference on Applied EconomicsAdvances in Quantitative Economic Research Mavromatakis Fotis Katsigiannis Ioannis Κατσιγιαννης Ιωαννης Haritaki Hara Siderakis Kyriakos Stavrakakis Georgios Σταυρακακης Γεωργιος Springer Renewable energy sources Photovoltaic technology Wind power Energy storage Net present value Internal rate of return Payback period
