Thermal Performance Upgrades: maximize power output

As power demand grows and operating conditions become more challenging, maximizing the value of your existing assets is essential to staying competitive. Whether you're looking for additional megawatts, greater dispatch competitiveness, lower operating costs, or reduced emissions, Siemens Energy Thermal Performance Upgrades (TPUs) can help you unlock the full potential for your gas turbine fleet.

Our Thermal Performance Upgrade strategy delivers proven improvements in power output, efficiency, and asset competitiveness: 

• Increase in GT efficiency
• Up to +30 MW additional combined-cycle power output*
• Up to +1.8 percentage-point combined-cycle efficiency improvement*
• Extended competitiveness of existing gas turbine assets

Results vary based on fleet configuration, upgrade pathway, and plant-specific conditions.

Thermal Performance Upgrades (TPUs) help gas turbine operators obtain additional power, improve efficiency, and enhance fleet competitiveness. Siemens Energy works with you to develop a customized upgrade roadmap that aligns with your plant configuration, operating conditions, and business goals.

Recent TPU implementations in Singapore, Peru, and the United States demonstrate how targeted modernization strategies can support evolving grid requirements without major new infrastructure investments.

Not every gas turbine requires the same Thermal Performance Upgrade strategy. The most effective upgrade pathway depends on:

• Gas turbine frame and configuration
• Existing service package and hardware condition
• Plant operating profile and dispatch strategy
• Generator, HRSG, and balance-of-plant constraints
• Business objectives and return-on-investment targets

Siemens Energy begins every engagement with a Thermal Performance Upgrade evaluation.

The gas turbine is the heart of your power plant, but its performance is closely connected to the rest of the facility. To help you understand the full impact of modernization opportunities, Siemens Energy offers a Technical Plant Assessment that evaluates key systems such as the HRSG, GSU, steam turbine, and auxiliary equipment. 

Unlock more value from your existing fleet. A Siemens Energy Thermal Performance Upgrade evaluation can help identify the modernization opportunities best suited for your operational requirements and business objectives.
