Power demand in Iran is growing at an annual rate of 7%. Iran has installed power generation capacity of about around 31.5 gw, of which around 80% is natural gas fired, with the remainder either hydroelectric or oil-fired. Iran is adding significant generation capacity, both thermal and hydroelectric, with the goal of reaching a total generating capacity of 40GW. The most recent official projections mention a total of 56gw by 2011. Although the government is considering privatisation, at present Iran's power sector is run by the state-controlled Tavanir organisation.
