Strategic R&D Plan Project PSE- MiniEólica Promotion of the Technology for Small Wind Three working areas are differentiated by targets : First Area: Product Development This area is focused on the support to the manufacturers in the development of their new products. Each line is leaded by one manufacturer which will be helped by technological research centres and private companies. New designs will cover the needs of the market in the power range between 20kW and 100kW. Second Area: Technical Development Breaking technological barriers and propitiate the technological development in key areas for SWT sector are the main objectives of this area. Those activities must be lead by technological R&D Centres and only in some cases by private companies. Technology research for medium-term application is attended in this area. Third Area: Activation of the SWT sector and support infrastructure development The objective of this area is the promotion, dissemination, sensitization and info collection for the SWT sector. Also in order to promote and adequate development of new products and business associated, a new infrastructures are needed, services has to be established (f. i. certification test facilities). A new called “minieolica sector” is pursuable. Organization of MINIEÓLICA Project:

Windlider 2015, is an industrial research project led by Spanish turbine manufacturers Gamesa and Ecotècnia. Its objective is to keep Spain at the cutting edge of wind power technology. Specifically, the project involves the design of new high-power machinery. Windlider 2015 has received a €13 million grant, almost half of its €28,5 million total estimated investment requirement. The project’s objectives are the following: To perfect design process of future turbines, reducing “time to market” and increasing maturity of the first series, considered vital to leading the market as of 2012 To boost Spanish-owned enabling technologies To create a holistic simulation model that reproduces as faithfully as possible the behavior of future turbines and determine the effect of new configurations, new enabling technologies and other factor on turbine performances To deploy several mid-sized technological-scientific infrastructures in Spain that permit experimentation in scales up to 5 MW with complete turbine prototypes and critical components (generators, gearboxes, converter, chasis yaw, etc.) CENIT WINDLIDER 2015
