Siemens Unveils 44-MW Mobile Gas Turbine

By Editors of Power Engineering

Siemens unveiled the SGT-A45 TR mobile gas turbine, which has an electrical generating capacity of up to 44 MW.

The company said the aeroderivative gas turbine is designed for rapid deployment and can be installed in less than two weeks. It also features strong power density, high fuel efficiency and operational flexibility.

Siemens indicated the new turbine would be especially helpful for customers with urgent power needs or in regions with less developed infrastructures.

Since the turbine’s design provides more electrical output than other comparable models, fewer turbine units will be required to produce the desired output, the company said.

The SGT-A45 TR design is based on previous Siemens products and Rolls-Royce Aero-Engine technology, and the turbine core uses components from the Siemens Industrial Trent 60.

The company has minimized the turbine’s size and weight in order to help facilitate transport and allow for air shipments. Both gas and liquid fuels can be use, and the turbine can transition between types while in operation.

Optional water injection can lower NOx emissions, as well as boost the power output capacity in warm climates.

Siemens estimates the unit can generate full power less than nine minutes from the start time with no need for auxiliary systems to maintain the unit in a standby mode.

“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.”
