至1997年,伊朗共有各类大坝230座,其中60座已建成运行,40座正在建设之中,其余130座正在进行各种前期研究。计划于1999年竣工的大坝包括水库库容为12亿m~3的Karkheh坝,库容5亿m~3的Tedzhen坝,以及坝高35m、库容5 000万m~3的Hana坝。预计到2020年,伊朗投入运行的水电站每年可发电40TW·h,这几乎是目前发电量的两倍。 By 1997, there were 230 dams of various types in Iran, of which 60 were completed and 40 were under construction. The remaining 130 are undergoing various preliminary studies. Dams planned to be completed in 1999 include a 1.2 billion m 3 Karkheh dam, a 500 million m 3 Tedzhen dam, and a 35-m Hana dam with a reservoir capacity of 50 million m 3. It is estimated that by 2020, hydropower plants put into operation in Iran will generate 40 TWh per year, which is almost double the current generating capacity.
