A New Standard in Operational Flexibility
Flexible performance features of the FlexEfficiency 50
Combined-Cycle Power Plant provide key operational
capabilities, such as:
•
Rapid Start in Less than 30 Minutes
—
the FlexEfficiency 50
Combined-Cycle Power Plant offers hot start capability
in less than 30 minutes with reduced fuel burn and
lower emissions.
•
Fast Ramp Rates
—
plant advancements result in a 51 MW
per minute ramping capability and improved load
adjustment capability, all within emissions guarantees.
•
Improved Turndown
—
the new plant offers turndown
of less than 40 percent of baseload plant output within
emissions guarantees, with development under way to
achieve 20 percent of plant load as an operational state
within emissions guarantees.
•
Fuel Flexibility
—
the plant can operate on natural gas or
distillate fuel, with a natural gas modified wobbe index of
+/- 10 percent to address fuel flexibility needs.
Flexible Starting Options to Meet Shifting Demands
GE’s FlexEfficiency 50 Combined-Cycle Power Plant offers four
distinct start options to provide operators with the flexibility to
meet the operating demands of the day.
•
Conventional Start
—
suited for a baseload plant with no
project Management
9
cycling needs and where higher startup emissions
are acceptable.
•
Smart Start Lite
—
suitable when some cycling is needed,
but the need for low-cost starts is predominant. This also
provides for low start emissions on hot starts.
•
Smart Start
—
provides for low start costs for negative
spark spread, with low start emissions on hot, warm, and
cold starts.
•
Rapid Response
—
provides the most flexibility with the
lowest startup emissions, and is well-suited for daily starts
and stops with positive spark spread.
An Innovative, Total Plant Design
The innovative total plant design provides a layout that
improves powertrain access and increases power density
by more than 10 percent over previous designs. The plant’s
reduced footprint together with a shaft centerline height of
5.5
meters—among the lowest in its class—results in cost
savings for foundations, enclosures, and buildings. Further
design improvements, such as locating major pieces of
equipment around the periphery of the power block, help
reduce maintenance costs and outage times while facilitating
faster construction, installation, and commissioning cycles.
GE’s FlexEfficiency 50 Combined-Cycle Power Plant is an
innovative, integrated approach that delivers a total energy
solution—quickly, efficiently, and effectively.
