Small hydro certainly does not match the amount

of installed capacity and generation of large

plants; however, with 1 to 30 MW per unit small

hydro still represents an option as a decentral-

ized solution for residential consumers, offices or

industries. Decentralized renewable energy can

help numerous local problems of energy supply

while respecting environmental commitments

including the Kyoto Protocol. Despite the fact that

small hydro power projects generally contribute

a small portion of most nations electricity needs,

their importance often exceeds their size.

The need for adequate access to energy and

water will continue to the primary developmentalconcerns in the future. Small hydro can also con-

tribute to this urgent need in an affordable way in

less developed countries of this world. It helps to

spur economic growth, stability, and sustainabil-

ity. Small hydro involves exploitation of a rivers

potential without significant damming.

Hydro power generally is not only environmen-

tally friendly, but also cost-effective. Hydro power

plants have the highest operating efficiency of

all known generation systems. They are largely

automated, and their operating costs are relative-

ly low. Hydro power plants also play an important

role in water resource planning: small hydro

plants very often provide residual flows to recon-

stituted areas, sometimes creating an even high-

er ecologically balanced environment. Small

hydro power systems, well designed, blend with

their surroundings and are in harmony with

nature.

Voith Hydro is a leader today in hydro power

equipment and services, including small hydro.

As an experienced partner to power plant oper-

ators, we provide fast, creative and cost-effective

solutions. We offer everything from individual

components to complete customized concepts,

from turnkey delivery of new plants to the mod-

ernization of existing power stations, truly an

opportunity for one-stop shopping.

As your complete hydroelectric partner Voith

Hydro also covers your service needs. In keeping

with our comprehensive hydro power expertise,

we have a worldwide customer service network

on which you can always rely for enhanced oper-ating results. Our small hydro concept includes

local manufacture, backed up by state-of-the-art-

technology and expertise from the most compe-

tent research and development centers in the

hydro industry.

Harnessing the power of water

with engineered reliability

Generating energy from the power of water represents large amounts of

clean, renewable energy. 71 percent of the earths surface is covered by

water. The worlds hydro power potential amounts to 20 billion Mega Watt

hours per year and only 30 percent of this has been developed so far.

Research and development

Small hydro development has always been

synonymous with Voith Hydro.

Voith Hydro Research and Develop-

ment is located in Heidenheims

historic Brunnenmhle. It can look

back at more than 100 years in

hydro power technology develop-

ment. It is the central management

and distribution center of knowl-

edge within the global network of

Voith Hydro and coordinates its

own and the US highly productive

hydraulic test labs. All development

can draw on standardized design

concepts with fully updated engi-

neering tools, whether for both

large and small hydro machinery.
