Exploring the offshore wind energy potential of Turkey based on multi-criteria site selection

Impact of Electrical Topology, Capacity Factor and Line Length on Economic Performance of Offshore Wind Investments

“…This offshore site is selected as a result of earlier extensive study based on a multi-criteria site selection work that considers many decision criteria in terms of technical (e.g., wind speed and sea depth), social and civil restrictions, that is, territorial waters, military areas, civil aviation, shipping and pipeline routes and environmental concerns [4]. It was also found in another earlier study [8] that the selected site is less favorable in terms of economics compared to other offshore sites in the Aegean sea since it is far from the point of common coupling which makes its electrical system investment cost higher.…”

“…Among the renewable energy resources, excluding conventional hydropower, wind energy has the highest share in terms of installed capacity [3]. Global installed wind power capacity has increased about 30 fold from 2000 to 2017, reaching a cumulative capacity of 591 GW at the end of 2018 [4]. Having higher wind energy potential due to less friction on water surfaces makes offshore wind farms more favorable over their onshore counterparts [5].…”

“…Energy economics metrics such as LCOE, net present value (NPV) and discounted pay-back period (DPBP) are calculated using a discounted cash flow analysis. The proposed analysis is implemented for a possible offshore site in the Aegean Sea, which was found to have the highest capacity factor among the 55 possible offshore locations in Turkey in an earlier study [4]. Two OWF sizes of 100 MW and 300 MW are studied to investigate the impact of electrical topologies on OWF economics in terms of installed capacity.…”

Strategic Planning of Offshore Wind Farms in Greece

“…Although several applications in various spatial planning scales can be found in the literature [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24], the applications of OWF siting at national scale are really handful. Only five out of seventeen [8,10,14,17,19], refer to site suitability analyses on a national spatial planning scale. More specifically, [8] applied five factors and seven constraints using multi-criteria decision making and GIS models to provide a suitability map for offshore wind energy in Egypt.…”

“…A spatial model for the assessment of offshore wind energy potential, production costs, and the identification of suitable areas based on GIS was presented in [17] and applied in a part of the Danish Exclusive Economic Zone (EEZ). Finally, a multi-criteria site selection analysis was performed by considering technical, social, and civil restrictions for finding the most suitable offshore wind farm locations in Turkey among the 55 coastal regions, including their technical power capacities [19].…”
