Siemens New 44-Megawatt Aeroderivative Gas Turbine For Mobile Power Generation

A product has been added to the Siemens gas turbine portfolio : The SGT-A45 TR mobile unit addresses the growing market for fast power . With an electrical generating capacity of up to 44 megawatts , this aeroderivative gas turbine is packaged for rapid deployment and can be installed in less than two weeks . Its design features outstanding power density , high fuel efficiency and excellent operational flexibility . This makes it particularly beneficial for customers with urgent power needs or in regions with less developed infrastructures .
This innovative mobile power generation unit from Siemens provides significantly more electrical output than comparable models currently on the market . This means that in most cases fewer turbine units are required to produce the total desired plant output . The SGT-A45 TR design is based on proven Siemens products and Rolls- Royce Aero-Engine technology . The gas turbine core utilizes components from the Siemens Industrial Trent 60 that have been adapted to a proven free power turbine . This design leverages the know-how and experience gained from millions of operating hours accumulated in flight , industrial and marine service .
The standardization and modular design of the package enable rapid deployment and installation . Each unit is fully assembled and tested at the factory in order to verify operation and performance and minimize the scope of commissioning work needed at site .
The mobile unit is an ideal choice for critical power needs . The package is built with durable industrial components capable of prolonged operation and demanding duties . The aeroderivative gas turbine can generate full power in less than 9 minutes from start without need for auxiliary systems to maintain the unit in an operationally ready standby mode . In the event of a shutdown , the unit can be restarted at any time to restore power quickly , as it has no “ hot lockout ” restrictions . “ This innovative Siemens gas turbine will provide flexible and rapid supply of electricity , enabling it to quickly support critical power needs ,” states Nick Muntz , CEO of Siemens ’ Distributed Generation business unit . “ The compact design of the SGT-A45 TR is especially well-suited for mobile power , for example in Africa or Southeast Asia , allowing us to capture a quickly growing market segment .”
The SGT-A45 TR gas turbine for mobile applications is part of Siemens ’ overall fast power concept : a range of power solutions designed for fast deployment to satisfy the needs and demands of each customer , particularly in fast-growth regions and places where infrastructure has not yet been fully developed . These standardized solutions are put through extensive testing after manufacture and , though relatively small and lightweight , deliver a high level of electrical output . These features facilitate transport to the destination by air , land or sea and enable very short installation times .
Transport of the gas turbine is facilitated by its compact design and relatively low weight . When required , the unit can be flown as air cargo to its installation site . The SGT-A45 TR gas turbine can run on gas or liquid fuels , and transition smoothly between both fuel types while in operation . This provides greater flexibility and ensures continued operation in case the main fuel supply becomes unavailable . Low NOx emissions can be achieved with optional water injection , which also boosts the unit ’ s power output particularly in warm climates .
