The Importance of the Steel Price in Offshore Wind
The price of some raw materials has been increased during the last 2 years. Firstly, the COVID pandemic and, secondly, the Ukraine-Russia war, have bringing a lot of economic consequences for the majority of the world's economies. The main purpose of the present paper is to analyse the importance of steel price in offshore wind. In this context, several economic indicators usually considered in energy industry, such as LCOE (levelized cost of energy) will be calculated. The method was carried out for a floating offshore wind farm composed by semisubmersible substructures and located in the main Atlantic Islands of Spain: the Canary Islands. Moreover, several cases of study with different prices of steel have been calculated in order to know the influence of this parameter in the economics of an offshore wind farm. Results of the three cases of study considered the highest economic variations are related to the internal rate of return and LCOE, with values of −7.6% and 5.4% respectively. Therefore, variations on the price of steel during last 3 years has repercussion on decisions about renewable energy, particularly floating offshore wind, where different types of materials for offshore platforms are being tested (steel or concrete, for instance).
期刊介绍：
IET Renewable Power Generation (RPG) brings together the topics of renewable energy technology, power generation and systems integration, with techno-economic issues. All renewable energy generation technologies are within the scope of the journal.
Specific technology areas covered by the journal include:
Wind power technology and systems
Photovoltaics
Solar thermal power generation
Geothermal energy
Fuel cells
Wave power
Marine current energy
Biomass conversion and power generation
What differentiates RPG from technology specific journals is a concern with power generation and how the characteristics of the different renewable sources affect electrical power conversion, including power electronic design, integration in to power systems, and techno-economic issues. Other technologies that have a direct role in sustainable power generation such as fuel cells and energy storage are also covered, as are system control approaches such as demand side management, which facilitate the integration of renewable sources into power systems, both large and small.
The journal provides a forum for the presentation of new research, development and applications of renewable power generation. Demonstrations and experimentally based research are particularly valued, and modelling studies should as far as possible be validated so as to give confidence that the models are representative of real-world behavior. Research that explores issues where the characteristics of the renewable energy source and their control impact on the power conversion is welcome. Papers covering the wider areas of power system control and operation, including scheduling and protection that are central to the challenge of renewable power integration are particularly encouraged.
The journal is technology focused covering design, demonstration, modelling and analysis, but papers covering techno-economic issues are also of interest. Papers presenting new modelling and theory are welcome but this must be relevant to real power systems and power generation. Most papers are expected to include significant novelty of approach or application that has general applicability, and where appropriate include experimental results. Critical reviews of relevant topics are also invited and these would be expected to be comprehensive and fully referenced.
