Italian oil firm Eni has awarded a €400m ($551.4m) contract to France’s Alstom for the engineering, procurement and construction (EPC) of a 740MW gas-fired captive power plant to support the expansion of production at the Zubair oil field in the south of Iraq.

Alstom will be responsible for the engineering, construction and commissioning of the facility on a lump-sum turnkey (LSTK) basis, as well as the supply of four GT-13E2 gas turbines.

Technical support and engineering expertise for the scheme will come from Alstom’s power generation headquarters in Baden, Switzerland, and its German gas turbine manufacturing facility in Mannheim.

This is Alstom’s third power plant contract in Iraq, following a $1.25bn deal in 2010 for a 1,200MW plant in Basra and a $450m contract in 2011 for the Al-Mansuriya plant northeast of Baghdad.

On 30 March, Eni also signed a $840m EPC deal with South Korea’s Samsung Engineering for the Hammar Mishrif degassing station, one of three major upstream oil facilities planned at the field.

Eni and its partners – the US’ Occidental Petroleum (Oxy), South Korea’s Korea Gas Corporation (Kogas) and state-owned Missan Oil Company – plan to increase oil production at the field to 850,000 barrels a day (b/d).
