Abstract(s)
Portugal é um país rico em recursos endógenos e o seu aproveitamento para produção de energia elétrica é evidente. O nível de eolicidade em Portugal torna o recurso eólico um dos principais impulsionadores da produção de energia elétrica. Cerca de 24% da demanda de energia elétrica [1] foi respondida através do Mix de energias renováveis e a tendência é tornar o país cada vez vais independente do setor dos combustíveis fósseis de modo a promover o equilíbrio relacionado com a temperatura terrestre e as emissões de gases poluentes para a atmosfera. A energia eólica tem um potencial instalado de mais de 5 GW, tecnologia essa implementada em 2006, consequência do maior consórcio eólico formado em Portugal, ENEOP. Toda a tecnologia instalada nesse ano estará a completar os 20 anos de vida útil garantidos pelo fabricante daqui a nove anos, o que leva a questionar qual o futuro da energia eólica em Portugal. Durante 20 anos a turbina eólica está sujeita a desgaste elétrico e mecânico e apesar das manutenções efetuadas, os fabricantes recomendam a substituição das turbinas eólicas ao final do término do tempo de vida. Como em todos os equipamentos, é necessário rever as condições de segurança e atividade sem colocar em risco os intervenientes e a “poluição” na rede elétrica. Assim sendo, restam três opções para a continuidade da produção elétrica através energia eólica em Portugal, o repowering, a extensão da vida útil do aerogerador ou o desmantelamento definitivo do parque eólico.
Portugal is a country rich in endogenous resources and its use to produce electricity is evident. The level of eolicity in Portugal makes the wind resource one of the main drivers of electricity production. About 24% of electricity demand [1] has been answered through the Renewable Energy Mix and the trend is to make the country increasingly independent from fossil fuels in order to promote equilibrium related to temperature and gas emissions into the atmosphere, which is both aimed at. Wind power has an installed potential of more than 5 GW. This is a technology implemented in 2006 thanks to the largest wind consortium formed in Portugal, ENEOP. All the technology installed this year will be completing the manufacturer's 20 years of service life within seven years, which leads to questioning the future of wind energy in Portugal. For 20 years the wind turbine is subject to electrical and mechanical wear and despite the maintenances made, the manufacturers recommend the replacement of the wind turbines at the end of its life time. As in all the equipment, it is necessary to review the safety conditions and activity without endangering stakeholders and the electrical grid. Thus, there are three options for the continuity of wind power in Portugal, Repowering, Extension of the life time of the wind turbine or the definitive dismantling of the wind farm.
