In the 1980s and 1990s Iran built several new natural gas, combined cycle (using both gas and steam), and hydroelectric power stations, dramatically increasing electric power output. Thermal plants supply 93 percent of the country’s electricity, and hydroelectric facilities provide most of the rest. In 1975 the government began building a nuclear power plant at Būshehr, on the Persian Gulf coast. The partially completed plant was bombed during the war with Iraq. In 1995 Russia signed an agreement to finish construction of the plant.
