Siemens has appointed RWG (Repair & Overhauls Ltd), a Siemens and Wood company, as its partner for new assembly and testing of the latest variant of its aeroderivative SGT-A05 gas turbine, the KB7 HE, following “a competitive tender process, evaluating potential suppliers based on stringent cost, quality and delivery performance criteria.”

Under this new agreement, RWG’s Houston facility is responsible for all aspects of the new build programme including sub-assembly, dynamic balance, engine assembly and factory acceptance testing. 

Rob Bouwens, Siemens SGT-A05 sales director, said “With a new high efficiency compressor and common design within our global fleet of engines, this product offers a compelling solution for new power applications, as well as retrofit of existing SGT-A05 (KB7S) installations.” 

Siemens acquired aeroderivative technology, including the SGT-05, through its acquisition of the Rolls-Royce stationary gas turbine business.

There are currently three variants of the SGT-05, rated between 4.0 MWe and 5.8MWe. Some 1475 have been sold worldwide for industrial applications, across a customer base of 500 operators in 53 countries, with more than 123 million operating hours amassed since first entry into service in 1963.
