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.
