Electricity Minister Karim Waheed told journalists in Baghdad that Iraq had signed a contract with General Electric to build three power stations in southern Baghdad the southern city of Kerbala, and Taji, north of Baghdad.
"According to the plan, the work will be completed between the end of 2009 and the start of 2010," Waheed said.
Iraq has also signed two other contracts, each worth $41 million, for GE to supply spare parts for the stations, he said.
Iraq said it had signed a 179 million euro contract with General Electric to buy eight natural gas-powered generators, most of which would be installed in Baghdad.
Five years after U.S. forces invaded to topple Saddam Hussein, and with violence at a four-year low, Iraqis are pressing the government to improve service delivery. Many areas lack access to electricity or drinking water.
With the onset of summer, when temperatures can reach 50 degrees Celsius (122 Fahrenheit), demand for power will increase as people turn on their air conditioners to keep cool.
Waheed said there was a wide gap between the consumption and supply of electricity in Iraq. Demand is around 10,500 MW, far above the 5,500 MW the grid is able to supply.
The minister said a contract would be signed with South Korean company Hyundai in Istanbul, Turkey, to supply Iraq with diesel generators. He did not give a value for the contract.
He said a contract would also be inked with German engineering group Siemens in Istanbul at the same time to supply Iraq with three "gas power units". He gave no further details.
