Siemens Launches 44-MW Gas Turbine

By Jack Burke21 March 2017

The new SGT-A45 TR aeroderivative gas turbine by Siemens is meant for mobile power generation, addressing the need for fast power with up to 44 MW output in electrical power.
Siemens said the turbine is packaged for rapid deployment by air, land or sea, and can be installed in less than two weeks. 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 the site. A compact design and relatively low weight facilitate the transport of the gas turbine, which can even be flown as air cargo to its installation site.
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.
According to Siemens, 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 gas turbine can run on gas or liquid fuels, and transition smoothly between both fuel types while in operation. Low NOx emissions can be achieved with optional water injection, which also boosts the unit’s power output particularly in warm climates.
The package is built with durable industrial components capable of prolonged operation and demanding duties, Siemens said. The aeroderivative gas turbine can generate full power in less than 9 minutes from start without the 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.”
