可再生能源发电（RES）对于实现欧盟的减排目标越来越重要。与此同时，欧盟的主要政策目标之一是为欧洲建立一个共同的内部能源市场。在本文中，我们将重点关注这两个先前分别研究的问题，并考虑它们之间可能的相互作用。我们首先分析了日前电价与燃料价格（天然气和煤炭）之间的长期关系，考察了两个以低RES渗透率和高RES渗透率为特征的年份样本，然后探讨了欧盟市场的一体化。我们发现，在2006-2008年期间发现的电力-燃料关系在2010-2014年期间发生了巨大变化。特别是，近年来，电力对天然气和煤炭价格的长期依赖程度大大降低。此外，我们的研究结果证实，随着RES-E的增加，被考虑的欧盟国家的一体化程度正在降低。我们的研究结果表明，国家实施的支持可再生能源的政策在提高可再生能源渗透率方面取得了成功，但它们减少了欧盟市场之间的联系，从而使整合更加难以实现。
Electricity generation from renewable energy resources (RES) has become increasingly significant to reach EU and emissions reduction targets. At the same time, one of the main EU policy goals has been the creation of a commoninternal energy marketfor Europe. In this paper, we focus on these two issues previously studied separately, considering their possible interactions. We first analyze the long-run relationship between day-ahead electricity prices and fuel prices (natural gas and coal) looking at two samples of years characterized by low and high RES penetration, then we explore the integration of EU markets.We show that the electricity–fuel nexus found over 2006–2008 changed dramatically over 2010–2014 for the majority of countries considered. In particular, the long-run dependence of electricity from gas and coal prices is much lower in recent years. Furthermore, our results confirm that the considered EU countries are becoming less integrated as RES-E increases. Our findings suggest that nationally implemented policies to support renewables are successful in increasing RES penetration, but they have lessened the linkage among EU markets, then making integration more difficult to obtain.
