Kashagan, an offshore field located at the north of the Caspian Sea, Kazakhstan sector, was discovered in July, 2000. Owned by a group of partners led by Agip, presently Kashagan could prove to be the world's fifth largest oil field. The field, 75 km SSE of Atyrau, lies in just 3.7 m of water. The field holds an estimated 7 billion - 9 billion barrels of recoverable oil resources and total geological reserves of 38 billion barrels.

A Power Plant has been provided as part of the Onshore Processing Plant to provide electrical power to be used by the Onshore Processing Facility (OPF), Eskene West Railway Project (EWRP) and early works camp. The Power Plant includes 110kV outdoor open terminal switchyard and 35kV and 10kV switchgear to facilitate distribution of electrical power. It will also include LV switchgear for turbine auxiliaries and other required supplies. In addition, provision is to be made for connection to overhead 110kV lines which are tied to the Kazakh National Grid system to allow import and export of electricity.

Heavy duty industrial turbines in the 35-45MWe (ISO) range have been used on this project. The Power Plant has been designed as a manned facility, which can initially operate independently from the OPF. A building will be designed and constructed, sized for three Essential Diesel Generators, together with its day tank and pumps. Three Essential Diesel Generators rated 6.5 MVA, 10 kV, 50 Hz, 1000 rpm shall be installed as part of Tranche 3.
