到2020年,欧盟可再生能源比例达到20%的目标为水电的发展提供了更多的机会,特别是小水电,可新增装机35%。在欧盟国家,除了小水电外,水电发展潜力主要来自于新建中型或大型水电站、开发抽水蓄能电站及现有电站的更新改造三个方面。欧洲小水电协会(ESHA)认为,在欧盟,现在运行的水电站约70%已服役40年以上,许多水电站需要更新改造以提高运行效率;目前,150多座水电站在实施更新改造。 By 2020, the EU goal of 20% renewable energy will provide more opportunities for the development of hydropower, especially for small hydropower, which will increase the installed capacity by 35%. In EU countries, except for small hydropower, hydropower development potentials mainly come from three aspects: newly-built medium- or large-scale hydropower stations, development of pumped-storage power stations and renovation of existing power plants. According to the European Small Hydropower Association (ESHA), in the EU, about 70% of hydropower plants currently in operation have been in service for more than 40 years and many hydropower stations need to be retrofitted to improve operational efficiency. At present, more than 150 hydropower stations are undergoing renovation.
