在北美洲,水电工业具有雄厚的实力。美国的水电站提供着占全国发电量13％的电力。包括常规装机和抽水蓄能装机在内,而加拿大60％的电力来源水电厂。美国水电的特点是:以分布广阔的现有工程为基础,提高每条连续径流河流的工程等级并进行新的开发。在1990年,有32个非联邦政府的工程投入商业运行,提供了61.3万kW的发电容量。这些工程体现了现代水电工业多样性的范例。其装机范围从缅因州(Maine)单个家庭拥有的50kW微型电
In North America, hydropower industry has a solid strength. US hydropower stations supply 13% of the country’s electricity. Including conventional and pumped storage installations, while Canada receives 60% of its electricity from hydropower plants. US hydropower is characterized by: building on well-distributed existing projects, upgrading the engineering grade of each successive runoff river, and developing new ones. In 1990, 32 non-federal projects were put into commercial operation, providing a generating capacity of 613,000 kW. These projects exemplify the diversity of the modern hydropower industry. Its 50kW micro-electric unit, which is owned by a single Maine family
