The designing part of GRI Renewable Industries aims to find the best solutions for the suppling the tower according to the demand and market needs, reduce energy costs and improve the annual energy production rate.
Supporting the Hybrid towers department, analyzing the different concrete designs, calculating and producing the most optimized tower in collaboration with OEMs in local targeted markets defined by the customer and the customizing of the towers accodring to type of wind, location, hub height…
In conclusion, R&D&i is developing the strategy of vertical integration across the value chain of the product, establishing the life cycle costs of the tower with the most optimal designs according to the specifications demanded.
The Spanish Ministry of Economy, Industry and Competitiveness, in the framework of the program “Retos-Colaboración 2016” of the National Plan of Scientific and Technical Research and Innovation 2013-2016, financed by FEDER funds from the European Union, has agreed to provide a three-year grant to the consortium formed by GRI Renewable Industries, S.L. (leader), Gestamp Wind Steel Galicia, S.L. and the research institution Aimen for the development of the project PROTOS.
The aim of PROTOS is to develop new and highly productive welding strategies for the wind tower manufacturing process that will enable us to decrease the total manufacturing process cost, bringing a significant upturn on the competitiveness of all companies involved.
The main activity of the project will focus on the development of new welding strategies oriented to catch up with the productivity ratios needed to compete at a global scale, regarding the size and weight of current wind tower trends. Offshore wind towers will benefit from this due to the importance of the welding activity in their manufacturing process.
The Center for Industrial Technological Development (CDTI) has granted financing to GRI Renewable Industries, S.L for the development of the “ROCKET” R & D project. The “ROCKET” project is focused on the development of new disruptive structural design solutions based on a new concept of systems that are joined to a central body that allow to obtain a reduction of the dimensions of the structure while maintaining the height of the tower, resulting in the achievement of significant advantages. This structural solution allows a significant reduction in the use of raw materials, manufacturing costs, logistics and assembly, having the capacity to design towers ranging from 140 to 200 meter of bushing, in accordance with the last generation of wind turbines. It also allows the execution “on site” in a modular manner. All this translates into greater productive flexibility, a reduction in the execution times in the work and, therefore, a reduction in the execution costs of the entire structure.
