Heavy-duty power plants

In today's complex power market Siemens Energy is a strong partner capable of providing you with competitive power plant solutions to improve the profitability of your business. We offer both simple cycle and combined cycle power plants turnkey from a single source. Tailored for your specific needs and challenges of the market. 

Duke Energy and Siemens Energy together have created a world record-holding power plant. The SGT6-9000HL at Duke Energy’s Lincoln Combustion Turbine Station is offering incredible efficiency, while delivering the highest power output for a simple cycle plant in the world. Read about how HL-class turbines help to reduce your carbon footprint today while looking to tomorrow.

Tailored to your needs

Are you looking for a highly efficient combined cycle power plant to cover base load at reasonable cost? Or a robust simple cycle power plant that will cover peak loads under tough conditions? Siemens Energy will develop and build the solution you need: simple and combined cycle power plants, with or without combined heat and power (CHP), flexible and sustainable. You can rely on proven technologies that will pay off throughout the entire lifetime of your power plant – technologies that set the standards in efficiency and reliability, and are fit to meet future challenges.

Performance And Efficiency Booster: HL-class

The next level of efficiency and performance 

With our HL-class gas turbine we are paving the way to the next level for higher power plant efficiency and performance. This evolutionary development step, derived from proven H-class technology, combines a series of new but already tested technologies. The result: A technology carrier to the next level with a combined cycle efficiency beyond 64% and a clear midterm goal of 65%. The HL-class consists of two engines:  SGT5-9000HL and SGT6-9000HL.

Proven And Highly Efficient: H-class Power Plants


Get the most out of your resources: a combined cycle power plant with a single H-class gas turbine will achieve an efficiency of about 62 percent and a power output of 675 MW (50 Hz) or 472 MW (60 Hz).

Highly flexible

Reliably cover your electricity needs: daily startup to full load operation in less than 30 minutes plus rapid load changes – our flexibility solutions will equip your H-class power plant for any load requirements.

Flexible And Reliable: F-class Power Plants

Suitable for every load profile

Stay flexible: our F-class Flex-Plants can be quickly started up and shut down. This means that you can cover peak loads as efficiently as well and intermediate and base load demands.

Profitable in the long term

Keeping an eye on costs: F-class power plants are especially service-friendly. Longer service intervals keep maintenance costs down – which means you get an ideal balance between capital costs, plant performance, and operating costs.

Robust And Durable: E-class Power Plants

Long-term dependability

Whether you need a simple single-shaft configuration or multiple lines, or a system combined with a steam turbine or heat extraction all of these run reliably under extreme conditions.

Wide range of firing options

Keep your options open: E-class power plants offer outstanding fuel flexibility – from low-calorific gases, gases containing CO2, H2S and Nto crude oil and other liquids with high viscosity.

Variable operation modes

Cover your peak loads: our E-class power plants can be rapidly started up, ramped and shut down. With no major efficiency losses, they are suited to operating with fluctuating power demand.

What you can count on

We are your reliable partner in all phases of a project: from business model design to financial closing, from technology selection to permitting, and from engineering to profitable operation – your success is our passion.
