SGT-400 Power Upgrade

The SGT-400 is a twin-shaft gas turbine available in different configurations and power ratings to support power generation and mechanical drive applications. The gas turbine offers the highest efficiency in its power class, incorporating the latest aerodynamic and combustion technologies. Since its introduction at 13 MW in 2001, Siemens Energy has been working with our customers and R&D experts to keep the SGT-400 at an industry-leading level of expertise. The 15 MW rating of the SGT-400 has been available to new customers since 2011, and this upgrade package is now available for existing customers to bring their assets to the leading edge of technology.

The power upgrade is generated by the changes in the compressor section to accommodate higher mass flow through the core. With the following key principles:

• This upgrade is built on accumulated operating experience of the SGT-400 13MW since 2001 and the 15MW since 2011
• This retrofit yielded a power upgrade between 0.6 and 1.5MWe. In general, the capacity of the customers AC Generator governs the specific upgrade power achievable. The exact increase in performance and work scope is required on a case-by-case basis.
• The 15MW core engine can be retrofitted into existing 13MW package as it retains common interfaces. (service exchange)
