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.

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.

“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.
