Flex-Plant™ Solutions
Flexibility for all your generation needs
Answers for energy.
Flex-Plant™ Integrated
Combined Cycles
Proven fast-start
technology
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 environmenta flexible, low emission partner
for renewables.

“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.”
“Siemens Flex 10
technology is helping
California to meet
aggressive environmental
goals regarding
intermittent resources and
new clean air standards.”

Flex-Plant
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.
300 MW of gas turbine power in10

Steam turbine start on the fly - hot
start of the entire cycle to valves wide

Faster, more efficient, dispatchable
power designed to significantly reduce
start-up emissions and start-up fuel costs,
can result in higher dispatch and
increased generation revenue.

MW/min (for a 2x1) with the capability
to maintain NOx and CO emissions
Ultra low water usage configurations
are available which keep footprint
down and water usage low.

Minimizing environmental impact was a top priority
in developing the Flex-Plant portfolio. These highly
efficient Solutions employ technology and techniques
that enable fast start-up, reduce CO emissions,
minimize water usage and ensure your plant is
available.

By choosing Siemens as your
integration partner, you can
expect a solution that provides
you with optimal flexibility.
Integrated
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.
The Power of Siemens
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.
Flexible Benefits
At over 80,000 strong, Siemens Energy
has the right people with the right
experience to make your power plant a
success.
10-minute megawatts dispatch
Flexible
Fast load following capability
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 FlexPlant 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.
Low load operation
Advanced design heat recovery steam
generator (HRSG) suitable for fast
start-up and daily cycling
With a Flex-Plant solution, you can
choose as little or as much as you want…
from a power island to a full turnkey
solution. No matter what you need, we
have the solution.
