Wherever they operate worldwide, utilities and independent power producers have to cope with rapid

changes - tougher emissions legislation and fierce competition not least among them.At the same time they need to reduce production costs yet major power interruptions dramatically

illustrate the danger of cutting cost at the expense of reliability. To increase long-term profits, even

at a time of volatile fuel and electricity prices, it is vital to continue to raise efficiency and productivity.

Alstoms GT13E2 gas turbine offers the highest engine efficiency of conventional class gasturbines yet has long inspection intervals. With millions of fired hours of operation to

its credit, the GT13E2 is the perfect core of a power plant, designed to produce reliable,competitively priced electricity.

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.

The GT13E2, whose gas turbine technology has earned its stripes over the years, is designedfor a wide range of applications. It 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 desalination plants. With its modularised and pre-tested

auxiliaries, the GT13E2 can be brought on-line quickly to support phased plant construction.

Right technology, right products

Alstoms gas turbines stand out for their high cost efficiency,

availability and flexibility.

The range covers a wide spectrum of products, including machines

for both the 50 Hz and 60 Hz markets. They can operate either in

simple cycle or combined cycle and are fuelled by natural gas,

medium or low calorific gases or light oil; with on-line fuel switch

over capability eliminating dependency on any one fuel.

Unmatched efficiencyThe GT13E2 has the highest open-cycle efficiency of conventional class gasturbines close to 37% (ISO) with a high exhaust energy level. This offers

significant fuel cost savings over competing technologies for a wide variety

of applications. It is achieved by carefully optimizing existing proven

technology without the need for expensive and high-maintenance

technologies used in some advanced gas turbines. The benefit of lower

operating cost is, therefore, not compromised by higher maintenance costs

or reduced availability.

Operational flexibilityThe GT13E2 can operate in either a performance optimised mode or a lifetimeoptimised mode without having to change hardware. Both respond to

increasingly volatile markets by allowing the operator to select, on-line, the best

operating mode to maximise profit. Operational flexibility also includes the

ability to handle wide fluctuations in gas composition. In addition, the engine

can operate on diesel oil (with or without water injection for NOx control), with

an on-line switch-over between gas and oil even at full load.

Low maintenance cost/longer inspection intervalsThe GT13E2 has a number of family assets. Firstly, the maintenance-free welded

rotor eliminates the need for major overhauls. Secondly, the fully annularcombustor does not require any combustor inspections. With the GT13E2, youcan achieve maintenance intervals of 36,000 Equivalent Operating Hours (EOH)

between hot gas path inspections. This makes the GT13E2 the ultimate choicefor operating regimes with a higher sensitivity to O&M costs and availability.

Continuous evolutionThe GT13E2 continues to be at the cutting edge thanks to constant technologyevolution. These incremental improvements use the engineering tools validated

at the Alstom Test Power Plant and confirmed with test campaigns in the field.

Two retrofittable upgrades on the GT13E2 are a prime illustration improved

turbine blading with the flexible operating concept and a compressor upgrade.

GT13E2:the benefits

8/12/2019 Alstom 13E2

4/20

Designed for dependable,low cost operation

The welded rotor design eliminates maintenance work such

as restacking and disk replacement or factory rotor overhaul

and thus eliminates the need for a so called major overhaul

of the GT.

Low-stage loaded compressorThe 21-stage compressor with its low stage loading yields

a high surge margin and high reliability.

Variable inlet guide vanes control airflow efficiently, increasing

part load efficiency and starting reliability.

Annular combustorA fully annular combustion chamber distributes the

circumferential temperature evenly while avoiding problem

zones such as cross-firing tubes or transition pieces. In

addition the annular combustion systems of Alstom do not

need a so called "combustor inspection" as for can-annular

systems which reduces the amount of maintenance leading to

higher availability.

Every component of the GT13E2 is the result oftime-tested design principles, thorough validation andmanufacturing processes conforming to the highest standards.

Maintenance-free welded rotorAlstoms welded rotor was first introduced in 1929 for steam

turbines and has been operating successfully in both Alstom

gas and steam turbines. The rotor is welded from forged discs

that ensure high rotor stiffness with two-bearing support.

Dry low NOx EV burnerEV (EnVironmental) burner technology, operating successfully

for several millions of hours throughout the Alstom gas turbine

fleet, gives long burner life, no maintenance between hot gas

path inspection and low emissions.

The EV 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 GT13E2s outstanding efficiency.

The design of the first turbine stage, combined with thermal

barrier coating (TBC) 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 systemThe straight-line arrangement of gas turbine and heat recovery

steam generator (HRSG) facilitates compact plant layouts.

The elimination of the turning elbow reduces back-pressure

and turbulence at the HRSG inlet. This improves unit

performance in simple and combined cycle mode.

Flexibility and efficiency

The longer and more flexible inspection intervals thatthe GT13E2 offers, linked to higher efficiency when required,provide the optimal hedging against fuel price uncertainty.

Extended inspection

intervalsOne of the key benefits of the GT13E2is the 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). You get this benefit with

only a marginal reduction in efficiency

and output. The GT13E2s optimisedoperation mode allows for 36,000

equivalent operating hours between

Hot Gas Path inspections.

Efficiency

The GT13E2 has the highest efficiencyof conventional class gas turbines insimple cycle. It offers unrivalled

performance in markets where fuel

prices are high or fluctuate regularly.

The combination of high power output

and high conventional class availability

in both simple and combined cycle are

compelling advantages. The

performance optimised operation mode

also offers the lowest Cost of Electricity

(CoE) when fuel prices are high.

The importanceof flexibilityWhere demand is seasonal or fuel prices

are volatile, the ability to switch between

operation modes on-line provides an

added operational advantage. The

GT13E2 has been designed to deliverthe high operational flexibility that allows

a plant owner to maximise profits with

the same hardware.

Meeting customer requirements

Our long experience working with customers andour understanding of different markets across the globeenable us to adapt to a variety of customer needs.

Low fuel prices

When fuel prices are low, O&M costshave a significant impact on the total

Cost of Electricity (CoE). To keep O&M

costs down, as plant owner you may

decide to run the plant with longer

inspection intervals. Using this operation

mode of the GT13E2, maintenancecosts can be contained since the EOH

Hot Gas Path inspection intervals run

to 36,000 equivalent operating hours.Furthermore, at around 0.2%, the

reduction in simple-cycle efficiency is

negligible. The contributions of O&M,

fuel and capital costs to the total Cost

of Electricity, and the preferable

configuration, are shown in the figure

below.

High fuel and/or

electricity pricesWhen fuel prices are high, the fuelportion of CoE becomes the dominant

cost factor. Here, efficiency has a huge

leverage effect. You cannot influence

the fuel prices, but you can strive to get

maximum power from the fuel to partly

compensate.

The performance optimised operation

mode of the GT13E2 assuresmaximum power - the highest power

output in its class, with the addedbenefit of high efficiency, both in simple

cycle and combined cycle, at high

availability and reliability levels.

In times of peak demand, when

electricity prices are high, switching to

the performance optimised operation

mode allows you to maximise

revenues. Alstom also offers integrated

inlet cooling and power increase

options that give even more operational

flexibility for following a variableelectricity demand.

Alba / BAHRAINPower station 3 & 42xKA13D-3, 723MW/2xKA13E2-2, 807MW

Fuel: natural gas/oil No.2 / natural gas

With an installed production capacity

of more than 800,000 tonnes per year,

Aluminium Bahrain (Alba) is currentlyone of the largest modern aluminium

smelters in the world.

The main power system supplying

the aluminium pot lines is run

independently from the national grid

system, thus puting some unusual

electrical system control requirements

on the captive power system. High gas

turbine and combined cycle flexibility

and continuous reliability are a must.

3/4 of Alba installed power generation

capacity is supplied by Power Stations 3

& 4 installed by Alstom. The GT13D gasturbines of Power Station 3 have been

continuously improved and upgraded,

resulting in increased performance,

extended inspection intervals, increased

expected lifetime and improved overall

availability. The NOx emissions have also

been considerably reduced.

The GT13E2s of Power Station 4 operatein the lifetime optimised mode and are

able to cope with the possibility of large

power surges.

The gas turbines GT13D and GT13E2have demonstrated their excellentcapabilities in powering an industrial

plant with stringent reliability and

flexibility requirements.

Pelican Point / AUSTRALIA1xKA13E2-2, 480 MW

Fuel: natural gas

In 1998, the government of South

Australia knew it would need to act

quickly if it was to prevent power

shortages. It decided to call on the

private sector; the result was Pelican

Point, a 500 MW combined-cycle

power project developed on a fast

track basis by National Power. The

plant increased South Australias

generating capacity by 20 per cent.

Alstom was awarded the turnkey

project in 1999 by National Power

South Australia Investments Ltd, asubsidiary of National Power plc. The

plant is equipped with two GT13E2

gas turbines and has been operational

since September 2000. The turbines

are equipped with advanced high-

efficiency, low-emission burner

technology to help meet the strict

environmental requirements at the

site. Alstom also supplied the overall

power plant control system, plant

engineering, and associatedinstallation and commissioning.

Lumut Extension /MALAYSIA1xKA13E2-3, 650 MW

important role in meeting Malaysias

increasing power demand. When

Alstom won the turnkey contract to

supply another block to the GT13E2based 1,400 MW combined-cycle

power plant Lumut in Malaysia, it

made the plant the largest independent

(IPP) CCPP in Southeast Asia.

After the 1997 crisis, the government

wanted a new peaking plant to be in

operation by the end of 2001. With an

existing plant at Lumut and therefore

an available infrastructure, it decided to

look at expanding the site to increasethe capacity of the plant. In order to be

operational before the projected

Lumut extension,

shortage, the new Lumut Block 3

would have to be given fast track

status, and in order to have power

available to meet the expected

demand, the project developers

invested in a bypass stack. This allowed

open-cycle operations so that 431 MW

would be available while work was

being done to convert the plant to

combined cycle.

The Lumut power plant is located in

the state of Perak, Malaysia. The

customer is GB3 Sdn Bhd, a fully

owned subsidiary of Malakoff Berhad.

Malakoff is the largest independent

power producer in Malaysia with a total

power generating capacity of over

2,000 MW. Alstom was responsible

for the supply of 3x165 MW GT13E2gas turbines, a steam turbine, three

They cover all plants (both existing and new ones), all energy

sources (from fossil fuels to hydro and nuclear), and all

emissions (NOx, SOx, Mercury, particulate matter).

Alstom offers the complete range of products designed to helppower plants to either reduce pollutant and CO2 emissions, or

to produce clean electricity from the outset.

For example, we deliver new coal-fired power plants with an

advanced supercritical design using proven clean combustion

solutions that are integrated with state-of-the-art emission

controls. Similarly, we improve the thermal and

environmental efficiency of existing power plants by

retrofitting plant components or upgrading the whole system.

Investing in the future of clean powerAlstom is uniquely placed as a plant integrator and full-serviceprovider to design and manufacture all the components

of a clean power plant, from turbines such as the GT13E2to generators, boilers and air quality control systems.

Alstom also invests substantially in the research and

development of new, environmentally friendly power solutions.

Together with partners, universities and customers in Europe

and the United States, we are working on collaborative

projects to develop solutions for pre- and post-combustion

CO2 capture and oxy-firing.

Research in actionIn addition to our own R&D efforts to develop new emission

control technologies and improve existing techniques, we are

also involved in a number of public projects and partnerships,notably in the field of CO2 capture and storage. The CASTOR

project (founded by the European Union) is studying

procedures for post-combustion separation that lower the cost

of CO2 capture and develop an understanding of the long

term storage mechanism. Within the ENCAP programme

(founded by the European Union), research is under way to

develop new pre-combustion and post-combustion CO2capture technologies. The Zero Emission Fossil Fuel Power

Plants (ZEP) technology platform launched by the European

Commission aims to develop and deploy new competitive

options for zero emission fossil fuel power plants.
