The IEC is one of the largest industrial companies in Israel, owning and operating an extensive nationwide power distribution network fed by 17 power station sites (including 5 major thermal power stations) with an aggregate installed generating capacity of 10,899 MW. Most of the base load electricity is generated using coal, though by the end of 2010 the company expected the majority (55%) of total installed generation capacity to be in the form of natural gas plants. In 2009, the company sold 48,947 GWh of electricity. To meet projected future electricity demand, an IEC capital investment program provided for the addition of 2,578 MW of installed capacity by the end of 2011. In addition, the government of Israel was seeking private companies to generate an additional several thousand megawatts by the middle of the 2010s, which would then be distributed by the IEC.
