Amobile 44 MW power generation unit, designated SGT-A45 TR, has been added to the Siemens gas turbine portfolio to address the growing market for rapid power. This aeroderivative is packaged for speedy deployment and according to its maker can be installed in less than two weeks. Its design features what Siemens says is outstanding power density, high fuel efficiency and excellent operational flexibility. This, and the standardisation and modular design of the package, makes it particularly beneficial for customers with urgent power needs or for use in regions with less developed infrastructures.

It also provides significantly more electrical output than comparable models currently on the market. Its design is based on existing Siemens products and the aero- engine technology that came with its 2014 purchase of the Rolls-Royce energy business.

The gas turbine core utilises components from the Siemens Industrial Trent 60 that have been adapted to mate with a proven free power turbine, a design that exploits the experience gained from millions of operating hours accumulated in flight, industrial and marine service. Each unit is fully assembled and tested at the factory in order to verify operation and performance and minimise 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 carried as air cargo. It 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. To answer the need for reliability the package is built with durable industrial components capable of prolonged operation and demanding duties. It can reach 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, commented: ”The new gas turbine for mobile applications is part of Siemens’ overall fast power concept, a range of power solutions designed for fast deployment … particularly in fast-growth regions and places where infrastructure has not yet been fully developed. These standardised 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.”
