Hydro – energy for growth and a cleaner environment

If you look at the growth rates in the
major hydro markets, such as China
Dr. Hubert Lienhard
and India, you will certainly see
Chairman of the Board
that they are way above the averof Voith Siemens Hydroage of any other country or region
Power Generationin the world. With this growth,higher standards of living and elevation of poverty are
inevitably connected. In order to boost both, clean, renewable energy for emerging economies and national infrastructure is necessary.
It is predictable that the worldwide need for energy will
outgrow the world’s current fossil resources. In addition,
until those resources are exhausted, the CO 2 levels in our
air will continue to increase if we do not strive for lowemission technologies for the future. Countries without
fossil fuel reserves of their own will have to either bear
the cost of importing or will have to look within for otherresources to match their growth. Hydro, in this context,
is not only a domestic resource, but also contributes toemissions reduction while generation still grows.
Enough energy, together with access to electricity, will be
the key drivers for future development and poverty alleviation worldwide. Countries such as India would rarely reachthis goal without a good share of hydro in their nationalenergy mix. The same is true for China. Nepal can evenavoid progressing deforestation through hydro power
development instead of burning wood for householdcooking and heating. In addition, trading this electricity
to neighboring countries is an important source for thecountry’s national income.

We can make a significant contribution to this development through our business. And we go beyond conventional hydro: While we are continuously improving ourcore business, we are also focused on a new aspect –wave energy. With the acquisition of Scotland-based
Wavegen, we have taken the first step toward technological development from this different form of “water power”,
and we will develop this emerging resource to maturity
and economically feasible solutions.
We’re comfortable in the water. For over 138 years, wehave been a leader in research and development for fluid
machinery. Technical expertise and services from within
the Voith group will support our wave energy development: drives and salt water-proven components from ourtransmission and marine technology divisions, services
in operation and maintenance from our own and Voith’s
industrial solutions division.
We will make sure that energy from water in every form
sustains a reasonable share in environmentally friendly
and low-emission energy generation all over the world.
We are interested in your opinions and comments;

Hydro power
drives development

Nepal, Solukhumbo,
boy carrying water container.

A view on the role hydro power is playing in Asian countries shows a lotof contrast. Nepal only utilizes approximately one percent of its extensivehydro power potential yet, Japan as a high-tech country has harnessed its
natural hydro resources almost completely, at least in the field of large
plants. The emerging hydro-superpower China develops its gigantic potential in quantum leaps. India’s ambitious target is to completely provide its
population of one billion with electricity by 2012, and thus plans to increase
its hydro power generation. This also promotes the interest of its northernmost neighbor – Nepal – to develop its own hydro projects.

Nepal – a natural country for hydro power

Gokoyo Lake, Nepal.

Ample hydro power opportunities
for private investors
Developing its hydro power potential,
Nepal could not only satisfy its entire
domestic energy demand but also
export power. The opportunities areabundant: India’s energy deficit isexpected to reach 20,000 MW by
2010, and China’s deficit will probably
pass 300,000 MW by 2015. Nevertheless, in order to harness and develophydro power, private sectors will haveto be involved. Nepal has undertakensome regulatory reforms and promulgated a new hydro power policy
attracting private financial sources.
Foreign investments are allowed tocover 100 percent of any hydro power
project and power exports to externalmarkets are possible.

hypower 11/2005

Nepal’s geo-physical conditions can be regarded ideal for the generationof hydro electric energy. Within a narrow width of around 100 km, the elevation changes from 8,840 m above sea level to less than 100 m, creating asubstantial head for any hydro power plant. The country’s rivers provide adependable flow, which is further enriched by ice and snowmelt.
The hydro power potential is estimated to exceed 80,000 MW, out of which
43,000 MW can be considered economically viable. But despite this enormous potential for future expansion, the Himalayan country only has maderather modest use of its hydroelectric resources to date. The abundantpotential remains almost entirely untapped since the total output of Nepal’shydro plants amounts to not more than 600 MW. Severe power shortages arestill quite common.

Focus on Asia: Nepal

Developing hydro power in Nepal
Dr. Janak Karmacharya,
Managing Director,
Nepal Electricity
Authority (NEA).

In terms of per capita hydro power potential, Nepal is on par with the UnitedStates of America. However, the United States have already developed 70%of their hydro power resources, whereas Nepal has managed to exploit only
about one percent of its technical and economical potential of 45,000 MW
so far.
Market potential in India to boosthydro power in Nepal
Slow industrial growth, unfavorable
topography, causing limited network
expansion, and the lack of adequate
infrastructure coupled with politicalinstability are the reasons for the
low development of hydro power
resources, even despite the fact that
Nepal is among the few nations in theworld where a specific hydro power
development policy has been promulgated. Nepal’s domestic electricity
market is relatively small compared
to its huge hydroelectricity potential.

However, the huge market potential
across the southern border creates aunique opportunity to develop hydroelectricity. On the one hand, thesouthern neighbor, India, is facing apeak deficit of approximately 13%; on
the other hand, Nepal has identified atleast 22,000 MW from storage projects, which include the 10,800 MW
Chisapani Karnali, 6,480 MW Pancheswore and 3,400 MW Saptakoshi
water resource projects. What isneeded now is a well-defined commercial tie with respect to powersales. The need of the day is to attract
investment through a politicallyassuring atmosphere and power sales
agreements with India.

Hydro power in Nepal – contributing
to overall economic growth andenvironmental preservation
Recent studies conducted in Nepal
have established the hydro power
sector as the main driving force foroverall economic growth in Nepal.
In order to bring the entire Nepalesepopulation above the poverty levelby 2027, nearly 22,000 MW of hydropower needs to be brought on line
for both the domestic as well as theexport market. Although rich in hydropower, only a small fraction of thecountry’s energy needs – three percent – is actually generated by hydro.
This has resulted in massive deforestation, as more and more fuel woodis used for satisfying current energy
demand. Only an extensive use ofhydro power could stop the trend ofincreasing deforestation. All thesefactors, considered together, leadto the necessity of expanding the
exploitation of hydro power also fordomestic use.

The quality of electricity supply in
India is another factor to be considered while assessing the market
potential. The requirements of the
Indian power system have beenassessed by the Government of India
to target a thermal-hydro generation
mix with the ratio of 60:40. This isnecessary in order to prevent thehuge industrial losses caused by peakshortfalls and frequency fluctuation
and will also help meet the goal ofproviding electricity to the entire
population by 2012.

Legal framework for hydro power
development
Policy changes are taking place bothin Nepal and India to promote thedevelopment of hydro power. Nepal,
as mentioned earlier, has promulgateda hydro power policy, which is considered to favor the private sector.
The “Hydropower Development Policy
2001” includes incentive provisions
and transparent processes for attracting private investors. Foreign investors
are allowed to invest 100 percent fordeveloping hydro power. Guarantees
against nationalization have been
provided, full repatriation of profit
and dividend is allowed, and foreignexchange is guaranteed. Time extensions caused by geological andhydrological risks are also provided.
Compensation for any additional costs
accrued from changes in the law isalso assured. Royalty rates are fixedfor projects supplying electricity todomestic as well as export markets.
A time-bound processing period has
been defined within which various
administrative steps must be completed by a one-window authority.
The developer is allowed to export
power to an external market.

The settlement of disputes will begoverned by the agreement or byprevailing law on foreign investment
and technology transfer.
An assured market, both inside andacross the Nepalese border, coupledwith a very supportive and friendly
policy ensures the development ofhydro power. The poverty alleviation
program is largely based upon development of these resources. Under
these circumstances, Nepal is boundto evolve into a major center of hydropower development in the foreseeable
future.

India’s power market –in need of an additional 100 GW
The Government of India recently
declared its target of giving its whole
population access to electricity by
2012. The Central Electricity Authority
of India has estimated that an additional 100 GW must be added to theIndian electricity system by 2012 inorder to satisfy the electricity needsof both the population and the industry. This would mean expanding the
installed capacity to more than
215,000 MW. By the year 2020 the
total requirement is expected to
exceed 300,000 MW. Currently, hydropower contributes only 25,000 MW
creating an enormous potential fordevelopment.

India – ambitious hydro plans

Hydro share to be doubled
The installed capacity of India’s hydropower stations represents roughly
one fourth of the Indian power mix.
There is an estimated potential of
150,000 MW of hydroelectric powerin the country, of which only about
one fifth has been harnessed so far.
Since the government clearly sees
the advantages of hydro electricity asa non-polluting and secure form ofenergy – contrary to thermal genera-tion, hydro is virtually unsusceptible
to price fluctuations – it has givenhigh priority to the development ofhydro power projects. Plans havebeen drafted to accelerate exploitationof the vast untapped hydro potentialand expand the hydro share to 40%.
An accelerated development planfor 162 sites with a potential of
50,000 MW has been launched by
the government.

Decisive role of public corporations
Major hydro power projects targeted
for development are concentrated in
the northern and north-easternregions of the country. Almost two
thirds of India’s new hydro projects,
totaling 20,000 MW of additional
capacity, shall be undertaken by
public corporations of the Central
Sector (federal government) by 2012.
The remaining share of planned
capacity additions will almost equally
be divided among private companies
and corporations of the respective
state governments. In the current
five-year plan (2002 to 2007) rehabilitation, modernization and upgrade
schemes as well as new projects withan aggregate capacity of more than
10,000 MW are included.

hypower 11/2005

A reliable and sufficient supply of electrical power is essential to guarantee
India’s future economic development. Today, India suffers from a significant
peak load shortage, and projections foresee a dramatic increase in energy
demand. To bridge the gap between demand and supply, total installedcapacities will have to be dramatically increased by 2012 to approximately
210,000 MW. Boosting hydro power capacities plays a prominent role in theambitious plan of the Indian government to achieve this goal.

China – the waking hydro giant

There is no other country that has increased its hydro power generation
capacity faster. Still today, only one fifth of China’s vast hydro power
potential is being utilized. As air pollution worsens due to the tremendous
number of coal-fired power plants, environmental awareness is on the rise.
Therefore, the Chinese government plans to increase power production
through hydro power by 8% every year.

Breathtaking pace of hydrodevelopment
Efforts to expand the generation ofhydroelectricity are already underway. There are several major hydroelectric projects presently underconstruction. The largest is theThree Gorges hydro power plant on
the Yangtze River with its foreseen
world record output of 18,200 MW.

When fully commissioned in 2009,
it will supply more than 100 million
people and the regional industry.
Several other hydro schemes withindividual capacities exceeding
1,000 MW have been brought into
operation recently or are approachingcompletion. More than 50 GW ofhydro capacity is planned for construction. Furthermore, China will
increase efficiencies of all its current
hydro power stations and also survey
small rivers to tap their hydroelectric
potential, especially in regions lackingof coal resources. The country’s total
exploitable hydro power resources are
estimated to be at least 290,000 MW,
ranking first in the world.

Japan – a well advancedhydro power market
With an installed hydroelectric generating capacity of more than 45 GW –thereof 25 GW in pumped storage schemes – hydro power contributes about
19% of total power generation in Japan, the second largest economy in theworld.
Due to its long history in hydro power
generation – the first Voith Siemens
Hydro machines were delivered toJapan already more than 100 years
ago – Japan commands a well provenand very advanced technology inhydro power generation. About 60%of the domestic hydro power potential
have been already developed.

Today, the large installed capacity
provides for a solid and major business in rehabilitation and modernization. Opportunities for new projects
are often driven by environmental
considerations which are supportedby the Japanese governement andcover mainly small hydro plants.

Micro tubular units –utilizing small hydro resources
Japan has an immense potential of low head schemes with an output of lessthan 100 kW. It does not come as a surprise that the micro tubular turbine
developed to exploit such energy was introduced there.

Micro tubular turbine installedon Egasaki Drinking Water
Treatment Plant (Serial arrangement of 2 units).

Hydro power resources can be harnessed not only from natural bodies

successful German hydro power
technology, its recent achievements
and further perspectives.

The “Brunnenmühle”, corporate
technology and research and development facilities of Voith Siemens
Hydro in Heidenheim, was among
several tour stops for this distinguished group.
In addition, the committee honored
Otto Eichler with the “1906 IEC
award” for his intense long-time
contribution to the efforts of numerous IEC working groups during his
35 years of active professional life

Investment into future-oriented wave energy
As a step to boost the development of innovative technologies for energy
generation from water and to assume a leading role in the field of wave
energy, Voith Siemens Hydro in May 2005 purchased Wavegen in Inverness,
Scotland.

Wave tank in Inverness.

Wavegen is also expert in so-called
power take-off (PTO) systems –power extraction systems operating
via turbines and generators.

For the commercialization of existing
technologies for near-shore power
stations, a number of projects havealready been identified. Consulting,concept, operating and maintenanceservices for wave-to-wire plants, aswell as the development of newtechnologies for energy generationfrom ocean currents, are also part of
the future activities of the company.
Voith Siemens Hydro envisages its
future strategic orientation, jointly
undertaken with Wavegen, in thecommercialization of existing technologies for shoreline and near-shore
power stations.

EssayTea – more than just a drink
With a worldwide annual production of around 2.9 million tons, tea is theworld’s most popular drink. In certain regions, however, it is much morethan that. In large areas of Asia, the aromatic infusion has been used forover 3000 years as a religious and cultural drink. The tea plant is, besides
rice and wheat, one of humanity’s oldest useful plants.

Man’s preoccupation with tea can be
attributed to the Chinese. Consumption of tea lay at the philosophical andcultural heart of the Empire.
Today, however, the largest consumerof tea is India, with around 640,000
tons annually, followed closely by
China with around 466,000 tons.
The nation with the largest tea consumption per capita is Paraguay,
where 14.6 cups are drunk per person
per day.
Numerous legends surround thediscovery of this drink. A gust of windis said to have helped the Chinese
Emperor Shen Nung (2737 BC). A few
tea leaves blew into a kettle of boilingwater and gave off an aroma thatappealed to him. The new drink
impressed the Emperor so much that
he introduced the entire land to tea
drinking.

In 552 AD, Buddhist monks brought
the art of tea preparation to Japan.
To this very day, the term “teaism”
refers to the Japanese people’s
almost religious devotion to tea.
In the 8 th century, several tea merchants commissioned the Chinese
author Luh Yü to write a three-volume
book about tea.
The result was the first documented
history of tea, which was at the sametime a hymn of praise for the highly
popular drink. Ever since, Luh Yü hasbeen regarded as the patron saint oftea.

Traditionally, tea is produced in four
different varieties. White tea – socalled because the downy hairs on theunderside of the dried tea leaves havea silver-white appearance – is madewhen young shoots are harvested
and, like herbs, dried without being
fermented. Only the best tea varieties
are suitable for preparation in thismanner. For green tea, the leaves
wither in iron pans over a fire before
drying. Oolong is produced by shaking tea in wicker baskets after harvesting, then fermenting the juice
released with the oxygen in the air.

This process is halted by heating theleaves in iron pans. Black tea – whichis actually called red tea in East Asia –is made in the same way as Oolong,
but the fermentation process is notinterrupted. The final tea product canthen be classified as “leaf tea”
(pekoe), “broken tea” (broken pekoe),fannings or dust, both of which aresuitable only for teabags.
The Champagne of tea varieties
comes from Darjeeling in North-East
India. The cultivated areas of the
3,000 km 2 region are at a height ofaround 2,000 m, on the south slopesof the Himalayas. Darjeeling teas havea light, gently aromatic flavor.
Assam from North India, grown ina high region, almost as large as
Germany, and near the Brahmaputra
river, is strong, dark and spicy.

Hangzhou in China produces a flowery, natural green tea. Tea from Japanis rarely seen in shops abroad, since
it is consumed in large quantities
within the country. The somewhat
cooler climate gives it a special
quality.
In Japan and China, tea is preparedand enjoyed rather differently fromwestern countries. Strainers are notused – on the contrary, hot water ispoured directly onto the tea in the cupor the pot. The wet tea leaves areheavier than water and therefore
break apart. Moreover, whole tea
leaves tend to be reused, and aresteeped up to three times. But regardless of the method of preparation, tea
gives water a flavor that is appreciated throughout the world – and thepurer the water, the better the tea will
taste.

Tea picking is a craft that requiresconsiderable experience, for the timeof picking has a considerable effecton the color and flavor of the end
product. Harvesting takes place up to
three times per year. In spring comesthe “first flush”, in summer the “second flush” and in autumn the “autumnal”. For the highest-quality teas, thepickers take only the bud and two
leaves from the shoot.
