Corporate News
Alstom’s gas turbines are designed for
high efficiency, availability and operational flexibility. The company’s gas turbine portfolio has a full range for both
simple- and combined-cycle units in
both the 50 Hz and 60 Hz markets. Fuel
flexibility with the ability to successfully
burn a wide range of fuels is also a characteristic of Alstom gas turbines.
To ensure that customer plants remain
competitive, Alstom Power Service provides technologies and experience to
develop and execute improvement packages to existing turbines. Besides being
the operation and maintenance partner
of choice for the Alstom fleet, power
service also invests in a substantial R&D
program, applying new turbine technologies while making use of the exhaustive fleet experience. Its turbine, compressor, combustion and system upgrades, as well as continuous component
improvements are designed to bridge the
gap between the latest developments and
existing gas turbine designs to keep
plants competitive with respect to
improved efficiency, reduced life-cycle
costs or environmental compatibility. a
Market Growth
GE Energy reports that it has seen
strong growth in its gas turbine activities
over the past few months, particularly in
the Middle East, highlighted by commitments in Saudi Arabia valued at nearly
US$2 billion. GE will supply 47 F-class
and E-class gas turbines for projects that
will add 6300 MW of capacity to the
Kingdom’s electricity grid. The country
is at the core of GE’s overall growth
plans for the Middle East.
payback through operational flexibility,
according to GE. Its first commercial
application was at the AEM Cassano
de’Adda Power Station in Milan, Italy.
GE Energy’s first LMS100 simple-cycle
gas turbine power plant entered commercial operation (see D>W, October
2006) at Basin Electric Power Cooperative’s Groton Generation Station located
near Groton, South Dakota, U.S.A.
Following the successful installation and
operation of this first unit, Basin Electric
later announced a contract for a second
LMS100 unit for the Groton station.
The LMS100 is designed to provide a
single, economical solution for a variety
of dispatch needs. A combination of
frame and aeroderivative gas turbine
technologies, the LMS100 delivers 100
MW with 44% thermal efficiency. The
turbine offers a wide range of operating
flexibility for peaking, midrange and
base-load operations with 10-minute
start times, improved hot-day performance, load following and cycling capabilities, the company reports.
Part of GE’s ecomagination portfolio,
the LMS100 reduces CO2 emissions by
more than 30 000 tons when compared to a typical simple-cycle 100
MW gas turbine plant over the course
of an average 2184 hour peaking season, according to GE.

Gas Turbine Development
Other GE gas turbine highlights from
the past 12 months include H Technology program progress, as the first two
Frame 7H gas turbines are being
installed at the Inland Empire Energy
Center near Riverside, California, U.S.A..
The power plant, the commercial launch
site for GE’s 60 Hz H technology, is
expected to enter commercial service by
the summer of 2008.
The first of three 50 Hz, Frame 9H gas
turbines is now being installed at Tokyo
Electric Power Company’s Futtsu
Thermal Power Station Group 4. The
project marks the commercial debut of
the H technology in Asia (see D>W,
May 2007).
GE has introduced its next-generation
dry low NOx (DLN) combustion system, the DLN 2. 6+, designed to reduce
NOx emissions by 40% on Frame 9FA
and 9FA+e gas turbines. The new system helps power plant operators meet
more stringent NOx control requirements while still providing economic
