Siemens introduces 44 MW aeroderivative based on Trent 60

Published on: 

A product has been added to the Siemens gas turbine portfolio: The SGT-A45 TR mobile unit. 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.

The SGT-A45 TR design is based on 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.

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.

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.

Nick Muntz, CEO of Siemens’ Distributed Generation business unit says: “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.”
