Under the contract, Siemens will supply six SGT5-4000F gas turbines, four SST5-4000 steam turbines and ten SGen5-1200A-series generators.
Siemens will be responsible to provide technical support for the project’s field erection and commissioning phases.
Planned to be built in the Umm al Houl Economic Zone in the south of the country, the facility will feature two power blocks, each in a 3+2 configuration.
Each of the blocks includes three gas turbines which will be used to generate the steam to drive two downstream steam turbines.
The power plant is being built for Umm al Houl, a consortium comprising the Qatar Foundation (QF), Qatar Petroleum (QP), Qatar Water and Electricity Company (QWEC), Mitsubishi and Tokyo Electric Power (Tepco).
Siemens Power and Gas Division Gas Turbines and Generators Business Unit CEO Theo Maas said: "This order is yet another indicator of the strong confidence that Middle Eastern countries have in Siemens’ technology.
"Thanks to our close collaboration with Samsung C&T right from the very start, this order also reinforces our excellent partnership with our partner and the customer."
The power plant, which also has a capacity up to 136 million imperial gallons of drinking water per day, is expected to account to almost one quarter of the nation’s installed power generating capacity.
The first phase of the project is scheduled to be completed in for 2017 while the entire complex is due to enter service in mid-2018.
In August, state-owned utility Qatar General Water & Electricity (Kahramaa) has awarded a €470m contract to Siemens to develop and deliver substations, to help meet power demands in the region.
The contract also covers switchgear, transformers, control and protection equipment, and the extension of four existing substations. Siemens will also build a 400kV Al Sakhamah super substation.
