Abstract:
The present work analyses the suitability of existing and planned wood-fired power plant in Portugal according to the forest biomass resource available for use as energy. Following the European Union strategy in climate and energy, which aims the decrease of greenhouse gas emissions and increasing the share of renewable energies (wind, solar, biomass, etc) consumption, Portugal established, in a first commitment, that the production of electrical energy from renewable sources should reach 45 % of the total supply by 2010. Further to the EU’s "20-2020" initiative, which set the objectives for 2020, the goal was increased to 60%. In order to fulfil this target, part of this energy will be obtained from biomass forest resources. Hence, in addition to the two existing electric power plants, with 22 MW of power capacity, 13 new power plants with 86.4 MW, are in construction. Despite the main goal is the electricity generation, the government incentive the construction of combined heating and power plants. Considering that wood-fuel demand will increase significantly across the different regions, it will be necessary to apply rational resource exploitation actions associated with regional and local needs. For example, there may be significant competition in some areas due to the presence of pulp mills or other biomass consuming industries. In these cases special solutions and compromises will be needed, or it may not be feasible to construct a power plant in such a location. This article evaluates if the biomass availability is sufficient to fulfil the future demands, considering two scenarios (fully condensing plants and cogeneration plants). The results show that if only electricity is generated some regions will need to find alternative fuel sources to fulfil the demand. However, if cogeneration is implemented the exiting wood fuel resource will be sufficient to fulfil the demand.
