Modernization and upgrades for large gas turbines

Gas turbine modernization is not just about extending the lifespan of your equipment—it’s about transforming the way your plant performs within a rapidly evolving energy landscape. Siemens Energy's comprehensive modernization and upgrade portfolio is designed to help you achieve higher output, improved reliability, greater flexibility, and a seamless transition to low-carbon operation.

Large gas turbines are at the heart of global power generation, providing flexibility and response required in today’s energy landscape. As the industry transitions toward cleaner, more efficient, and more flexible solutions, Siemens Energy stands at the forefront—delivering tailored modernization and upgrade packages backed by decades of operational and engineering expertise, advanced technology, and proven results.

Siemens Energy’s commitment to innovation is reflected in a comprehensive suite of upgrade solutions, each engineered to address the evolving operational, efficiency, and sustainability needs of today’s gas turbine fleet.

Turbine blades, rotors, combustion chambers, and control systems can be upgraded with state-of-the-art materials, coatings, and designs derived from Siemens’ HL-class turbine technology. These upgrades substantially reduce component degradation, improve performance, and expand the operating envelope—even in harsh conditions. 

Upgrading combustion systems allows for cleaner fuel burning, lower emissions, and compatibility with alternative fuels including higher hydrogen blends. Solutions offered include Dry Low Emissions (DLE) upgrades, advanced burners, and combustion monitoring technologies. 

These advanced technologies and strategies represent the backbone of Siemens Energy’s modernization portfolio, empowering operators to unlock new performance, reliability, and flexibility from existing assets.
