Siemens understands that change is the only constant in the energy market. Environmental needs will always be a driving factor and operational flexibility is a competitive must. The fundamental element of a Flex-Plant solution is environmental responsibility. Siemens’ integrated technology enables unsurpassed operational flexibility that helps maintain your competitive edge regardless of market changes.
Siemens Flex-Plant is the energy solution designed to bring technology for tomorrow - to the industry today.
The Flex-Plant™ portfolio of solutions is centered around the Siemens
SGT6-5000F and SGT6-8000H Gas
Turbine packages. The SGT6-5000F is the only 60-Hz gas turbine operating today that can generate 150 MW in as little as 10 minutes without additional maintenance penalties.
The SGT6-8000H is the 60 Hz version of the gas turbine that powers the first power plant in the world to exceed 60% combined cycle efficiency.
The confluence of efficiency and flexibility makes the Flex-Plant a good steward of the environment- a flexible, low emission partner for renewables.

“Siemens Flex 10 technology is helping
California to meet aggressive environmental goals regarding intermittent resources and new clean air standards.”
John Chillemi, President of NRG’s West Region, owner and operator of El Segundo Energy Center
Integrating proven, fast-start technology in a high-efficiency, three-pressure reheat combined cycle, the Flex-Plant can achieve full load in less than half the time required by traditional combined cycle plants.
Start-on-the-Fly
Integration of a Siemens Flex-Plant frees the gas turbine and steam turbine to start, stop, load and unload fast and with reliable predictability. With steam turbine start on the fly, the full Flex-Plant combined cycles can be up and running in less than an hour.
Clean-Ramp ™
Siemens Clean-Ramp technology enables the Flex-Plant to stay in emissions compliance, while load following renewables. This unique, patent pending feature integrates the control of the gas turbine and the SCR to enable low emissions out of the stack while ramping up or down. At Siemens, integration of the combined cycle is the key, and our
Clean-Ramp technology is the next step in our evolution of friendly integrated power generation.
With the Flex-Plant fast synchronization,
10-minute megawatts are a reality.
“The plant’s cutting edge technology will help strengthen electrical system reliability as variable renewable resources continue to be deployed to achieve
California’s important, clean energy goals.”
James H. Pope, General Manager, Northern
California Power Agency, owner and operator of
Lodi Energy Center CCPP (U.S.)

The fast-start technology incorporated into the Flex-Plant can greatly reduce start-up emissions compared to a traditional combined cycle plant and maintains low stack emissions during operation – and also reduce the amount of fuel needed to get to load.
Its not just the environmental footprint that is small. Siemens Flex-Plant are available in ultra low water usage configurations with small air cooled condensers (ACC) and smaller plant footprints.
The Power of Siemens
At over 80,000 strong, Siemens Energy has the right people with the right experience to make your power plant a success.
Flexible
Whether your economic model requires plant shutdown, turndown, or high efficiency base load operation, the
Siemens Flex-Plant technology offers the flexibility to do it all. A Siemens Flex-
Plant solution allows you to operate your plant at peak profitability. You have the confidence that your plant will be online fast when you need it. When turndown is the preferred mode, the Flex-Plant is capable of running overnight, at as little as 13 percent of its rated load, while maintaining environmental compliance.
If load following to match grid demand is a priority, the Flex-Plant, with its 75 MW per minute up and down capability, as well as its available integrated automatic grid control (AGC), will meet this need.
