This article aims to analyse the economic viability of floating wave energy farms for present and next twenty years. The potential waves mainly depends on climate, so current near future analysis is crucial determine in a particular location. Current resources were considered assess main parameters (Net Present Value (NPV), Internal Rate Return (IRR) Levelized Cost Energy (LCOE)) that allow know feasibility farms. study takes one step forward determining evaluation located deep waters using...

ABSTRACT The price of some raw materials has been increased during the last 2 years. Firstly, COVID pandemic and, secondly, Ukraine‐Russia war, have bringing a lot economic consequences for majority world's economies. main purpose present paper is to analyse importance steel in offshore wind. In this context, several indicators usually considered energy industry, such as LCOE (levelized cost energy) will be calculated. method was carried out floating wind farm composed by semisubmersible...

This paper uses a method to analyze the economic influence of size floating offshore wind farms. The aspects analyzed, LCOE (Levelized Cost Of Energy) and costs, depend on number turbines, which establishes effect farm. has been carried out for map in specific location. Regarding case study, 18 alternatives have considered taking into account total power farm types platforms. These studied location Galicia (Spain). Results indicate how costs vary when is increased kinds structures. are...

The goal of this work is to carry out an economic analysis a novel floating offshore wind structure, which the main material concrete: SATH® platform. It takes step forward in marine energy research, traditional platforms are mainly composed steel. technique calculate costs platform and parameters decide if farm economically feasible explained paper. This case study analyzes possible 500 MW located Portugal several scenarios considering different electric tariffs capital (Scenario 1: tariff...

This paper defines a methodology for the economic feasibility analysis of floating offshore wind farm composed tensioned leg platforms, which are part EU ARCWIND research project. In this context, phases and subphases its life-cycle process considered to deal with aspects such as bathymetry, characteristics distance from shore, port speed. All costs other external parameters capital cost, electric tariff, interest rate, percentage financing corporate tax have been analysed calculate internal...

The aim of this paper is to determine the main costs and feasibility repowering wind farms. For purpose, two study methods, which depend on legal turbines issues, have been considered. They will provide nine alternatives, whose be developed. methodology has applied particular case Galicia (North-West Spain), where there a good onshore resource. Calculations indicate costs, Net Present Value (NPV), Internal Rate Return (IRR), Pay-Back Period these alternatives. In addition, sensitivity...

Wind energy resources are subject to changes in climate, so the use of wind density projections near future is essential determine viability and profitability farms at particular locations. Thus, a step forward determining economic assessment floating offshore was taken by considering current near-future assessing main parameters that (net present value, internal rate return, levelized cost energy) farms. This study carried out along Atlantic coast from Brest Cape St. Vincent. Results show...

The aim of this paper is to examine the most relevant competitive factors a shipyard.The method conducted interviews and questionnaires with multiple agents related company analyzed several institutional, business, academic documents.The case study considered was manufacturing center Navantia, S.A. in Ferrol estuary (A Coruña, North-West Spain).The results indicate that five important are government political support, production organization, product technology, manpower, skills...

The aim of this work is to develop a software calculate the economic parameters so as determine feasibility floating offshore renewable farm in selected location. can several types energies, follows: one energy (floating wind-WindFloat, tension leg platform (TLP), and spar; wave energy-Pelamis AquaBuoy), hybrid wind systems (Wave Dragon W2Power), combined waves with different (independent arrays, peripherally distributed uniformly non-uniformly arrays). user select inputs, such location,...

This study describes the technical and economic aspects of repowering process for wind farms in Bustelo S. Xoan, situated municipalities Muras (Lugo) As Pontes de Garcia Rodriguez (A Coruna), Galicia, North-Western Spain. was result a growing demand renewable energies, facilitated by great potential energy Galicia. Both were set up 1998. The other factors they have common - same type machinery, their location shared substation- mean can be studied together independently.

The objective of this paper is to examine the economic aspects a concrete offshore wind floating platform in Atlantic Arc Europe (Portugal and Spain). life-cycle cost considered calculate main parameters that will define feasibility farm. case study Telwind®, spar with revolutionary way installing using self-erecting telescopic tower turbine. In addition, analyses thirteen locations Spain twenty Portugal, including islands both countries. Results indicate economically feasible location...

The objective of the present work is to develop a sensitivity analysis determine most essential parameters that affects economic feasibility marine wind farm composed by platforms built in concrete material. main purpose analyze how input variables such as number offshore turbines, energy produced one turbine, interest rate, capital cost, electric tariff, etc. affect output variables: Levelized Cost Of Energy (LCOE), Internal Rate Return (IRR), Net Present Value (NPV) and Discounted Pay-Back...

The aim of this study is to use two different methodologies for calculating the energy produced by a total wave farm in Cantabrian Sea (North Spain). First method studies taking into account converter power matrix and probability sea conditions particular location. On other hand, second more simplified methodology which not taken account, but it considers density water, gravity, period height wave, as well percentage efficiency, among others. Finally, generated economic parameters that allow...

Reactive power is an important parameter in electrical systems since it affects the efficiency of system because not useful energy. It decreases factor and limits ability generators to deliver power. therefore necessary understand correctly measure phenomenon reactive energy three-phase systems.
