The main objective of the project is to design, develop, construct and operate a grid connected 16 MW high energy efficient power plant in the southwest of Spain to be 100% fuelled with a significantly abundant biomass agricultural residue: corn stover. As a result, the further project objective is to demonstrate the plant high operation availability (over 8000 hours/year), its overall economic and technical feasibility, and to encourage the development of further similar biomass power plants in Europe in accordance with the EU energy strategies recently laid down in the Biomass Action Plan, SET plan and other related European policies. In order to reach the objectives, the project is led by a globally known industrial promoter of renewable energy installations, Acciona Energía from Spain, gathering a partnership with the most experienced European developer of industrial feeding systems from Finland, an SME with demonstrated experience in high technology boiler manufacturing, a technological centre experienced with power plants life-cycle analyses, and two Finnish and Danish centres acquainted with the current state-of-the-art knowledge on combustion of herbaceous biomasses. Around 28 million tonnes of corn stover are produced annually in Europe, of which considering that only 30% of it would be feasibly collected, about 75 plants in the range of 15-20 MW could be set in Europe in 2009-2015, which would supply about 10.4 TWh (Terawatt-hour) annually to the electricity grids for the use of the citizens
