Welcome to Alstom

Both highly versatile and highly efficient,
Alstom’s GT13E2 truly sets the standard.
GT13E2 the latest evolution of gas turbine technology
Alstom’s GT13E2 gas turbine delivers the highest engine efficiency of any conventional
class gas turbine, coupled with long inspection intervals. With millions of fired hours of operation
to its credit, it provides the perfect core for a power plant, designed to produce reliable, competitively
priced electricity.
Utilities and independent power producers face rapid changes – tougher
emissions legislation and fierce competition not least among them. We know our customers need the
high levels of efficiency and performance that the GT13E2 delivers. Its combination of high power
output and high conventional class availability in both simple and combined-cycle plants has made it
first choice with operators across the world.
The GT13E2 offers superior flexibility through two operating modes one
maximises performance, the other maximises operating time between inspection intervals. In addition,
the engine can actively support grid frequency with high response and no extra lifetime factors.
In the power industry, versatility is key. The GT13E2 provides exceptional performance
for a wide range of applications and can operate as a stand-alone turbine in a new or existing power
plant design or as part of a turnkey power plant. Applications cover electrical power generation in base
load, intermediate or peak duty. It can be used in industrial applications such as aluminium smelters
or cogeneration plants, like district heating or desalination. Finally, its modularised and pre-tested
auxiliaries mean it can be brought on-line quickly to support phased plant construction.
03
Operational flexibilityToday’s markets are volatile. To maximise profit, the
GT13E2 can operate in either a Performance Optimised
Mode or a Maintenance Costs Optimised Mode: one
maximises performance, the other maximises operating
time between inspection intervals. With no change in
hardware, plant operators simply respond to market
changes by selecting the best mode online. The turbine
can also handle wide fluctuations in gas composition
while the engine can operate on diesel oil (with or
without water injection for NOx control), with an online
switch-over between gas and oil, even at full load.
Greater efficiency. Meeting the power
Key benefits
Unrivalled efficiency The GT13E2 has the highest open-cycle efficiency of
any conventional class gas turbine, with a high exhaust
energy level providing significant fuel cost savings.
Unlike many advanced gas turbines that come with high
maintenance costs or reduced availability, in creating
the GT13E2 we have optimised our existing proven
technology to add these fuel cost savings without
compromising in other areas.
In an unpredictable energy market, the GT13E2 makes
it simple to switch between operation modes.

In an unpredictable energy market, the GT13E2
makes it simple to switch between operation modes.
Easier maintenance / reduced repair workWith the GT13E2, operators can achieve maintenance
intervals of 36,000 Equivalent Operating Hours (EOH)
between hot gas path inspections. This makes the GT13E2
the ultimate choice for operating regimes with a higher
sensitivity to O&M costs and availability.
VersatilityAs well as covering electrical power generation at base
load, intermediate or peak duty, the GT13E2 provides a
cogeneration solution.
Ideal for industrial applications such as aluminium smelters,
district heating or desalination plants, it makes use of exhaust
heat to generate thermal energy for a range of applications.
It has been designed for superior performance under all
conditions including extreme heat or cold.
Continuous enhancementWe are constantly evolving the GT13E2, keeping it at the very
cutting-edge of turbine technology. We do this by making
incremental improvements.
The GT13E2 had three upgrades so far, perfectly illustrating
the way we make these enhancements: every upgrade to our
turbine blading compressor and combustor has increased
performance, boosted operational flexibility and reduced
maintenance time.
Higher performance industry’s high demands
05
Maintenance-free welded rotor Alstom’s welded rotor was first introduced for steam turbines in
1929 and has been operating successfully in our gas and steam
turbines every since. The rotor is welded from forged discs that
ensure high stiffness with two-bearing support. This design
eliminates maintenance work such as restacking and disk
replacement or factory rotor overhaul. It also removes the need
for ‘major overhauls’.
Low-stage loaded compressorThe 16-stage compressor with its low stage loading yields a
high surge margin and high reliability. Three rows of variable
guide vanes control airflow efficiently, increasing part load
efficiency and starting reliability, with improved environmental
turndown.
Annular combustorA fully annular combustion chamber distributes the
circumferential temperature evenly while avoiding problem
zones such as cross-firing tubes or transition pieces. Alstom’s
annular combustion systems also do not need any ‘combustor
inspections’ as for can-annular systems. This reduces the
amount of maintenance leading to higher availability.

Dry low NOx AEV burnerOur AEV (Advanced EnVironmental) burner technology is
a further refinement of the EV burner, which has operated
successfully for several millions of hours throughout the Alstom
gas turbine fleet, with a long burner life, no maintenance
between hot gas path inspection and low emissions. The
AEV burner gives the benefit of dry low NOx combustion for
operation with different natural gases, with the option to run
with liquid fuel as an alternative.
TurbineAdvanced aerodynamics and multi-convective cooling schemes
contribute significantly to the GT13E2’s outstanding efficiency.
The design of the first turbine stage, combined with thermal
barrier coating and conservative firing temperatures, allows
extended inspection intervals of up to 36,000 EOH. All Inconel
738 conventional cast turbine airfoils and heat shields ensure
long parts life and allow for full, cost-effective refurbishment.
Axial exhaust systemFor power producers limited on space, the straight-line
arrangement of our gas turbine and heat recovery steam
generator (HRSG) facilitates compact plant layouts. By
eliminating the turning elbow, plant owners also benefit
from reduced back-pressure and turbulence at the HRSG
inlet, improving performance in both simple and combined-
cycle mode.

and performanceDelivering outstanding results
Extended inspection intervalsOne of the key advantages of the GT13E2 is its ability to
operate with extended inspection intervals for low fuel cost
applications or in schemes where fuel is provided by the power
off-taker (Tolling or Energy Conversion schemes). The GT13E2’s
Optimised Operation Mode allows for 36,000 equivalent
operating hours between Hot Gas Path inspections. Plant
operators can receive this benefit with only a very marginal
reduction in efficiency and output.
EfficiencyIn simple cycle turbines, the GT13E2 provides the highest
efficiency in its class, delivering unrivalled performance in
markets where fuel costs are higher or fluctuate regularly.
Its Performance Optimised Operation Mode also offers the
lowest Cost of Electricity (CoE) when fuel prices rise.
The importance of flexibilityThe GT13E2 has been designed to deliver high operational
flexibility. This includes the ability to switch between operation
modes online. If demand is seasonal or fuel prices are volatile,
this ability to switch modes without changing hardware brings
a crucial advantage, maximising profits.
PerformanceThe GT13E2 delivers exceptional performance coupled with low
emissions at full and part load with low turndown. The world’s
most reliable heavy-duty gas turbine, it offers a fast start and
high load gradients as well as a frequency response in the wide
load range. Plant operators benefit from its high fuel flexibility
and power augmentation options.

Seamless integrationSimple.
Alstom engineers work
in partnership with our
customers to meet every
requirement.
Developing, building, and operating a profitable gas turbine
power plant goes far beyond selecting the best components.
A key aspect is integration, which can substantially enhance
flexibility and performance.
As a leading EPC contractor, we approach every integration
project with the following list of requirements for our gas
turbines:
The gas turbine should be designed for simple and cost
effective integration into the overall plant.
In-depth, comprehensive user information should be
readily available.
Application consulting should be available when required.
Plant owners add the following requirements to the list:
Operational flexibility to support plant dispatch requirements
such as quick start-up, fuel flexibility, black start, power
augmentation, air inlet cooling.
Operational stability to accommodate sudden load changes,
active grid frequency support, black grid restoration, partial
or global load rejection.
An efficient Operation & Maintenance regime.
With the Alstom GT13E2 gas turbine, all the above come
as standard.
The GT13E2 is backed by Alstom’s plant operating and
maintenance service expertise, with a portfolio including any
level of service from spare parts delivery up to full operation and
maintenance. Operational support is also available on a 24/7
basis with the on-line Alstom Monitoring and Diagnosis System
(AMODIS).
The GT13E2 is the result of years of Alstom experience in
gas turbine plant design and construction. This experience
goes back to the world’s first commercial gas turbine plant in
Neuchâtel, Switzerland, in 1939. Today, Alstom is the leading
EPC contractor worldwide, with technology for all plant
components in house.
