Seite 3Voith Siemens Hydro Power Generation
The sustainable approach in hydro businessIf somebody asked: “Where are thebig hydro markets for the future?”
the likely answer would be:“China, India, and in the not too
distant future, Brazil, again.”Dr. Hubert Lienhard
Chairman of the Boardof Voith Siemens Hydro
Power Generation

Wouldn’t it be nice to simply focus on these markets or
wait for some of them to come back? China and India
certainly have the most concrete energy development
plans with big shares in new hydro. India is just announcing a 50,000 MW hydro program. And, of course, we areproud to be a partner in this development through ourpresence there. Brazil may be expected to soon offer
opportunities for the new and rehab hydro business again.
In other areas of the world, however, this comeback or
new development of hydro is not so clear and forecastable. If you look, for example, at the regions of the former
Soviet Republics and Eastern European countries, overall
development in their economies is difficult. Despite thefact that these countries very often have substantial
hydropower installations in abundance, capital investment
is low for hydro development.
How can we sustain new or spark redevelopment in areas
like this? How can we help hydro as the most mature
renewable and sustainable “fuel” in the energy mix ofthese countries?

Hydro investments have always been slow in coming;
they are large capital projects with long life-cycles of
50 years and more, with high upfront costs. For shortterm planning the return on investment of these projects
is not spectacularly high. Still, we believe that we canhave a sustainable approach to this market, as evidenced
in the articles in this issue, showcasing the roles we playin the development of Russia, Armenia, Bulgaria and also
Afghanistan, are just the beginning. What we have to offer
in this issue are examples of our patience and sustainability in this business. Another fine example of long-term
efforts comes from India. After many years, the Shrinagarhydro project in India is ready for development. Throughour U.S. developer company, Synergics, all commercial
aspects of project development have been completed andwe have arrived at the phase where Tata Power has takenover as our national partner.
We have the technology, the business platform, thefinancial background and the expertise to get the job
done.
We look forward to working with you to protect andfurther develop this most precious resource.
We are interested in your opinions and comments,
please feel free to direct them to me personally.

Hydro back on the rise

Russia’s giant power sector has a total electricity generation capacity ofmore than 200 GW and in 2001 generated approximately 846.5 billion KWhof energy. After the collapse of the Soviet Union, electricity generation
declined dramatically between 1992 and 1999, but since then has gradually
recovered. The power industry of the biggest country on earth includes
440 thermal and hydropower plants and 30 nuclear power plants.
Hydro power plays an important rolein the country’s electricity supply.
According to recent statistics of thegovernment-owned Unified Energy
Systems (UES), approximately 44 GW
come from hydro, representing 21.5%
of Russia’s total installed capacity.
Typical of the Russian power industry
is the use of large-capacity generating
units.

The largest hydroelectric stations in
Russia are the Sayano-Shushenskayastation (6,400 MW), the Krasnoyarsk
station (6,000 MW), and the Bratsk
station (4,100 MW).
The economic recovery after theAugust 1998 financial crisis resulted
in an increase in the country’s total
electricity consumption, and has
forced power stations to operate at
higher capacities. This has broughthydropower plants into sharper focus
since they do not depend on fossil
fuels.

The Russian government has statedthat it intends to expand the role ofnuclear and hydro power in the
future. Particularly in Siberia and thecountry’s far east, where electricity
supply can be problematic, the government has made hydroelectric
generation a priority.

Russia’s giant Bratsk station –modernization
When completed in 1961 after 7 years of construction, the Bratsk hydropower plant with its total output of 4,100 MW was the largest hydropower
station in the world. Today, it still ranks among the largest and most important hydropower stations in Russia. Located on the Angara River in Siberia,
it supplies the city of Bratsk and its giant aluminum smelter with electric
power.

was ordered at the end of last year.
Since the 18 units at Bratsk areworking on three different bus bars,
interconnected by transformers, thiscontract poses a certain challenge
for Voith Siemens Hydro engineers.
They will have to find a solution tocontrol not just the total powerhouse
output, but also the balance between
the bus bars. A challenge they are
eager to face: the joint control system
will be commissioned this year.
The complete modernization process
is scheduled to be finished by 2006.

Bulgarian hydro potential
supporting energy export

Bulgaria’s energy sector is dominated by nuclear power and imported fossil
fuels. The energy balance for the country shows that more than 70% ofenergy consumption is based upon imported fuels. Hydro power accounts
for only 6-7% of all electricity generation.
Despite a very large potential for
future expansion, Bulgaria’s hydroelectric resource utilization can only
be described as modest. However, as
electricity production still exceeds
demand after the decline of energyintensive industry branches of theformer COMECON area, future hydrodevelopment will come as a result ofenergy exports to Bulgaria’s neighboring countries.

In 1999, the total output of the country’s hydro plants was 2,979 GWh, ofwhich 351 GWh were consumed inpumping mode. The 14 largest plants
operate in four cascades, generating
power to meet peak demand andprovide system regulation. Thesefour cascades are: the BelmekenSestrimo-Chaira, Batak, Arda in the
Rhodopes mountains, and the
Dospat-Vacha cascade in the Rila
Mountains.

Modernization of all Rila cascade stations
After almost eighty years of successful operation, Granitoid, the ownerof the oldest hydropower cascade in Bulgaria, has entrusted Voith Siemens
Hydro with a major modernization of the project. In February, a frame
contract for modernization comprising new mechanical equipment, electrical balance of plant systems as well as a state-of-the-art automation
system, was signed by Granitoid and Voith Siemens Hydro.

The Rila hydropower station, also
mainly Voith equipped, produces thehighest power and began operationin 1928, followed by the generating
stations of Kamenitsa in 1940 and
Kalin in 1948.

In March 2003, Granitoid awarded
Voith Siemens Hydro the contract forthe design and supply of a hydraulically optimized runner with increased
efficiency for its oldest plant, Pastra 1.
In a second step, after positive experience gained during project execution of Pastra 1, Granitoid scheduled
upgrades for the whole cascade.
Again, Voith Siemens Hydro wasselected by Granitoid to perform thework, including a range of new runners, new wicket gates and turbine
shaft seals as well as the rehabilitation of other mechanical components

to ensure a proper interface with the
new equipment. Another importantfocus of the modernization is on
automation. The contract scope also
includes the supply of new turbine
governors, control systems, lowvoltage switch gear, static excitationand electrical protection for all seven
units, all four power plants and thecascade dispatch center located in
Rila. Granitoid plans to release rehabilitation work unit by unit from theframe contract on the basis of modernizing one unit per year.

As early as February 1925, the first
generating unit of the cascade, a Voith
Francis turbine with a rated output of
2.4 MW, had been commissioned andput into service at Pastra hydropower
station. Pastra is the oldest within acascade of four hydro plants in the
Rila mountains, which are the highest

Armenia – hydro power
as a key to future development

Following a severe economic decline in the early 1990s, Armenia today
is continuing its recovery. Small- and medium-sized enterprises, most ofwhich have already been privatized, have spurred continuing economic
growth. Armenia’s real gross domestic product grew by approximately 6%
in 2003.

In order to improve infrastructure
conditions, an appropriate minimum
supply of electrical energy to businessand private households is crucial.
Approximately one fifth of the energy
generated in the country is derived
from hydro power. Armenia’s hydropower potential is huge, but currently
only a small part of this single major
native energy source is exploited.

The capacity of all hydropower plants
installed in the country is a little morethan 1,000 MW. The improved utilization of hydro power is one of thegovernment’s objectives, in order toachieve greater independence fromenergy and fuel imports in the future.
It is to play a key role in the development of this Middle East republic.

Seite 9Modernizationof the Vorotan cascade
After 33 years of service, the availability of the generating facilities at
one of the largest hydropower cascades in Armenia has fallen clearly below
the original values. Highest priority rehabilitation measures are now to be
carried out.
Although designed as peak-load plant,
Tatev is currently the only station
permanently operated in active grid
regulation mode. Originally commissioned in 1970, its units are showing
signs of deterioration.
In order to improve availability,
enhance operating capacity and reacha modern level of automation, extensive modernization works will now be
carried out by Voith Siemens Hydro.

Works include rehabilitation of theturbine governors, reconstruction of
the Pelton nozzle assembly, replacement of cooling water pumps and air
compressor equipment as well as thereplacement of battery systems at
two power stations and the supply of
a control system together with fieldmeasuring equipment.

For the future of Afghanistan:
Rehabilitation of Sarobi and Mahipar
Voith Siemens Hydro has been awarded the rehabilitation contract for theSarobi and Mahipar hydropower plants, not far from the Afghan capital
Kabul. The contract, which is worth 16.6 million EUR, was concluded with
the Ministry of Water and Power in December 2003. The project will befinanced by a loan from Germany’s KfW (Kreditanstalt für Wiederaufbau,
Credite Institute for Reconstruction).

Both projects are extremely importantfor safeguarding power supplies toKabul. At present, the connections
from the Sarobi and Mahipar power
plants to the city grid are overloaded
because of the poor condition of theplants, which were originally equippedand commissioned by Voith andSiemens in 1956 and 1966 respectively.
Only 117 MW of the installed hydrocapacity of 266 MW are currently
available.

Moreover, two 110 kV lines and the
distribution network have been partly
destroyed, which means that power
supplies are rationed daily and almost
half of the existing connections are
only supplied with electricity every
other day.

Measures in detail
The rehabilitation measures are
therefore key projects for the central
region of Afghanistan. In the Sarobi
hydropower plant, the existing units
will be completely modernized andthe capacity of every machineincreased; in Mahipar, two of thethree existing units will be partiallyreplaced and repaired.

Sarobi area

Voith Siemens Hydro will supply allelectro-mechanical parts for Sarobi,
including Francis turbines, generators,
governors and spare parts as well as
installing them and monitoring thecommissioning process. The firstmachine is scheduled for commissioning in July 2005.
For the Mahipar power plant refurbishment is planned in two steps. The
first includes delivery of new components and spare parts. In a second
step – also financed mainly by KfW –the already delivered equipment will
be installed and additional repair
measures will be executed directly onsite in close co-operation with the
Afghan experts.

Mahipar inspection scene

The future of the plants
The signing of this second phase wasdone on February 15, 2004. The firstunit of Mahipar will be completely
overhauled in June 2005. However,the contract covers much more thanmerely supplying the technical fittings
and fixtures for the power plants:
Voith Siemens Hydro experts willtrain the Afghan plant personnel atboth sites, thus ensuring that they are
optimally prepared for operating theplants after they have been commissioned.
By this time, Sarobi and Mahipar will
have an installed total capacity of
91 MW. The rehabilitation measures
will therefore make a considerable
contribution to increasing and safeguarding the energy supplies which
are the basis for the sustained reconstruction of the country.

The work will be co-ordinated fromthe Siemens office in Kabul, which
was reopened in 2003 and which is
carrying on the tradition started bySiemens and Voith during their morethan 70 years in Afghanistan. Voith
Siemens Hydro will continue to support hydropower development in the
country through its local presence.

Redevelopment in Egypt’s
powerful Aswan High Dam

Seven kilometers from Aswan lies the Aswan High Dam. Nearly four kilometers in length, the 111 m high Aswan High Dam links the banks of the Nile.
One of the largest artificial lakes in the world lies behind the dam andimpounds almost 164 billion cubic meters of water covering an area morethan 500 kilometers in length.
From the very beginning, energy
generation was a central aspect of theplant, which was erected between
1960 and 1971. Between 1967 and1970, Aswan High Dam was equippedwith twelve Francis turbine units witha total rated output of 2,100 MW. It iscapable of generating a considerable
share of Egyptian energy demand,
54% of the total generated power in
Egypt in 1978, and still a remarkable
16% in 1998. That year, total annual
capacity of the hydro station at Aswan
High Dam exceeded 10 billion KWh.

In order to safeguard the crucial
generation of clean energy for the
future, rehabilitation measures arenow scheduled to be carried out
during the next six years. Last October,
Voith Siemens Hydro in consortiumwith Power Machines, Russia, signed
a contract with the Egyptian Ministryof Electricity and Energy in Cairo forthe rehabilitation of the generators for
Aswan High Dam hydropower station.

Voith Siemens Hydro is the leading
partner in the consortium and is
responsible for the overall project
management, basic and detailed
design, along with its partner PowerMachines, as well as the statorrewindings for six generators, rotor
windings and monitoring systems for
all twelve units. Power Machines, theoriginal supplier of the electricalcomponents of Aswan High Dam, will
be responsible for managing theRussian contribution of supplies andservices as well as for the manufacturing and erection of some of theequipment.
The project is financed by Germany’s
KfW (Kreditanstalt für Wiederaufbau,

Successful collaboration with trusted partners
in Kürtün, Turkey

The well-established collaboration between Voith
Siemens Hydro and its Turkish partner, TEMSAN, marked
a new stage in December 2003: the Kürtün hydropower
project in the north-east Anatolian province of
Gümüshane was brought to a successful conclusion.

Both machines were equipped forturbine operation mode and condenser operation mode. The units areable to provide active and reactive
power to the grid. As in the previous
joint projects in Kralkizi, Suat Ugurlu
and Beyköy, TEMSAN manufactured
all the important steel components
such as draft tubes, spiral cases,
guide vanes and shut-off valves in
the local market.

Forecast
In the future, Kürtün will generate
80 MW from two Francis turbines,
each with a runner diameter of
2,600 mm, rated at a head of 83.6 m,
thus contributing to a stable frequency and voltage level in the highvoltage network of electricity supply
to the area.

Expertise in automation

Replacement of remote monitoring
and control on Germany’s Moselle River
In the 1950s and 60s, the development of the Moselle River as a major
shipping lane also gave rise to the opportunity of erecting ten run-of-river
power stations between Koblenz and Trier. They have been generating
electricity for more than 40 years.

Central control room in Fankel
In all, 17 power stations on the
Moselle and 7 on the Saar are monitored and controlled from the central
control room in Fankel (near Cochem).
In co-operation with Siemens, Voith
Siemens Hydro has been progressively replacing the entire remote monitoring and control system in Fankel
since August last year.

From this switching center, which ismanned around the clock, the entire
run-off process of the two rivers is
controlled primarily for shipping, as
the water level of the Moselle may
only fluctuate by +/- 5 cm on eachreach. The remote terminal units of
all 10 German Moselle power stations
are also to be replaced.

In this way, exact operating data forthe operation of the power stations
can be obtained by continuous automatic measurement of the waterlevels.
With the precise data calculated in thecentral control room in Fankel, each
local power station can then manually
regulate the run-offs.
Through this exact regulation of waterlevels, the power station operator,
RWE Power AG, can ensure that thewater is sufficiently deep for shipping. The commissioning of thecompletely replaced control systemwith all substations is scheduled forJuly this year.

News from China

Successful model acceptance for Longtan
In September 2003, the successful model acceptance for the Chinesehydropower station Longtan took place at Voith Siemens Hydro’s Central
Technology facilities. The model turbine for the second largest hydro power
project in China after the Three Gorges project was intensively tested in thepresence of the customer, Longtan Hydro Power Development Co.
The contractually required guarantees and operating regimes were fulfilled
to the customer’s satisfaction.

The Longtan hydropower plant islocated on the Hongshui river in the
Guangxi province in the south of
China. This location makes Longtan
a key project: in the future, thehydropower station will supply electricity to both, the previously rather
underdeveloped south-west and theenergy-starved eastern regions.
It will be equipped with seven vertical
Francis turbines with a rated capacityof 714 MW each and a runner diameter of 7.9 m. These huge runners
present a logistic challenge, as it is
not possible to transport finishedrunners of these dimensions. The
runners will be manufactured at site
by the consortium members Voith
Siemens Hydro Shanghai and Dongfang Hydro Electric Machinery Co.
For this purpose, a special building
with production workshop is foreseen
near the hydropower plant.

The contract was awarded to theconsortium in January 2003 and theentire hydraulic and mechanical basic
engineering executed by Voith
Siemens Hydro. The share of Voith
Siemens Hydro will be engineered
and manufactured by Voith Siemens
Hydro Shanghai.
The first unit is scheduled for commissioning in 2007, the project will
be completed in September 2009.
Once it is complete, Longtan will be
among the largest hydropower stations in the world with a total capacityof 5,000 MW.

Hydro 2003 in Dubrovnik, Croatia,
awarded Blue Planet Prize

The 400 MW plant, located near CapeTown, was honored for excellence inthe development and operation of ahydropower scheme, assessed on thebasis of technical, economic andenvironmental criteria.
Palmiet was commissioned in 1988
by South African utility Eskom andSouth Africa’s Department of Water
Affairs and Forestry to provide system stability for the country’s electricgrid, and also to provide an extra
water supply to the Cape Town region.

Right from the start of construction,
extraordinary measures were applied
to minimize the impact of construction on the environment and to protect the unique Cape flora.

Meanwhile, the area has subsequently
been designated a UNESCO biosphere,
which testifies the positive role hydropower can play even within the mostenvironmentally sensitive zones.

Since commissioning, great care forthe local environment has continued
to be a high priority, for example bymonitoring the program to preventthe ingress of non-native fauna andflora.

Every two years the International
Hydropower Association elects candidate hydropower schemes for the Blue
Planet Prize. Up to three schemes
may receive the prize in each award
cycle. With the support of UNESCO’s
International Hydrological Program,the Prize was first awarded in 2001.
The aim of the Prize is to increaseawareness of hydropower’s contribution to sustainable development andto promote good practice in the useof the world’s hydropower resources.

Essay

Venice of the North
This distinction is claimed by St. Petersburg, the most
northerly, and to many people the most beautiful city
in Russia. Like “La Serenissima” itself, the lives of its
citizens are heavily influenced by the water that surrounds them.

It is visited by over three and a half
million people every year. Heading
east from the Hermitage, you come to
Nevski Prospect, a wide, magnificent
boulevard which is the city’s mainpromenade.

Early in the eighteenth century,Peter the Great had the city laid out
as single, monumental work of art,with the intention of making it the
new capital of the Czar's empire.

Located between the estuary of the
Neva River and Lake Ladoga, the city
extends over an area of 606 square
kilometres, of which 58 square
kilometres are covered by water.

Until the 18th century Russia had nosea way to Europe. At that time, tradeby sea was very important for the
economic development of the country.
After having won the exit to the Baltic
Sea, Peter I gave an order in 1703
to build a fortress on the bank of
the Neva River with the aim to havemilitary fortification on the river anda commercial gate to Europe.
His famous words were: “We will cut
through a window to Europe”.
After the “Petersburg Fortress” – thatis how Peter I named it – and later
the trade fleet had been built, hetransferred the capital of Russia from
Moscow to Petersburg.

Built on 44 islands around theFortress of Peter and Paul, St. Petersburg has 540 bridges. The Admiralty
was chosen as the centre of the road
network. At this shipyard the Czar laid
down a mighty fleet of vessels which
he used to open a “window to theWest” from his new city and start a
brisk and profitable trade with theEuropean monarchies.

St. Petersburg has seen manychanges in the course of its history.
Wars, upheavals and two revolutions
have influenced its development.
In 1905, the citizens of St. Petersburg
defied the Czar until he signed theOctober manifesto, opening the way
to Russia’s first parliament.

Near the Admiralty, the Royal Palace
was built later, as was the Winter
Palace, which today houses the
Hermitage, one of the most comprehensive art collections in the world.

In February 1917, the Czar was forced
to abdicate, and the Soviets took
control of the city under Lenin’s
leadership. From that time on the city
was called Petrograd, but as a tributeto the state’s founder following his
death, was later renamed Leningrad.

In 1991, the citizens voted in a referendum to revert to the original nameof St. Petersburg.
In spite of its restless history,
St. Petersburg has maintained its
classical appearance. The panoramaof buildings along the banks of the
Neva is breathtaking, and the countless small watercourses create aromantic atmosphere that is certainlycomparable to that of Venice.

Today, St. Petersburg – some 651 kilometres from Moscow – is the mostimportant center of Russian science,
culture and commercial activities.
The birthplace of Russian president
Vladimir Putin, it was restored atconsiderable expense in 2003 to celebrate its 300 th anniversary, and its
former brilliance now shines forth
again. These efforts attracted considerable international recognition andhave been a strong influence forcurrent and future investments, both
domestic and foreign.

St. Petersburg was heavily industrialised even before the First World
War. Today, the focus is on ship andmachine building, and also diverse
foodstuff and light industries. The
city has the most important Russian
port on the Baltic Sea and an important inland harbour at the end of thewaterway that connects the Black Sea
and the Volga with the Baltic.

Fyodor Michailovich Dostoyevski(1821-1881) was one of many to beinspired by the city. The world-famous
author was the creator of the philosophical Russian tragedy, and gave
the city an immortal literary monumentwith his greatest novel, Crime andPunishment.
