Siemens has been awarded a 25-year long-term service agreement for the planned Umm Al Houl combined cycle power plant in Qatar. The customer is Umm Al Houl Power Q.S.C., a company established through a partnership among Qatar Electricity and Water Company (QWEC), Qatar Petroleum (QP), Qatar Foundation (QF) and K1 Energy (joint venture established by Mitsubishi Corporation and TEPCO Fuel & Power, Incorporated).
The service agreement covers the plant’s six SGT5-4000F gas turbines, four SST5-4000 steam turbines, 10 SGen5-1200A generators including instrumentation and controls service for a period of 25 years. It also provides for an electrical and a resident engineer to be located on-site.
The new power plant will be located 15km south of the capital Doha, adjacent to Qatar Economic Zone. The plant will consist of two power blocks, each in a 3+2 configuration. Each block will consist of three gas turbines which will be used to generate the steam to drive two downstream steam turbines. With a total electrical output of 2.5 GW, and up to 618 million liters of drinking water per day, the plant will deliver almost one quarter of the nation’s installed power generating capacity. It will ensure adequate power and water supply to accommodate seasonal fluctuations and major events. Commissioning of the first phase is scheduled for 2017, with commissioning of the entire complex scheduled for mid-2018.
