During 2010 Pakistan floods and 2005 Kashmir earthquake power stations, power distribution and transmission and other energy infrastructures were damaged. During the floods and rainfalls the recently constructed Jinnah hydroelectric power plant was flooded in addition to severe damages to transmission and distribution network and installations while several power plants and refineries were threatened by rising waters and had to be shut down. Natural gas field output had to be reduced as the flood waters approached the wells. There has also been some concern by Pakistani nuclear activists over the effect of natural disasters on nuclear plants specially over the Chashma Nuclear Power Plant, since the plant lies over a geological fault.
