Integral Solutions
IMPSA is a global company which provides integral solutions for
power generation from renewable resources. Since its creation
in 1907, it has grown continuously to become what it is today,
a company: committed to its customers, creating high-value
total solutions, socially responsible towards the communities it
works with, with a profound environmental awareness, and with
a long-term commitment to research on and development of
s
ustainable technologies.
IMPSA is now organized in business units as shown above.
From an in-depth understanding of its customers’ needs, IMPSA
has developed an interesting mix of products through the following
business units:
IMPSA HYDRO
• Hydropower Projects under EPC (Engineering, Procurement and
Construction) contracts;
• W2W supply;
• Core Equipment;
• Rehab of Hydro Power Stations;
• Operation and Maintenance (O&M);
• Life Cycle Services.
IMPSA WIND
• Wind Farms under EPC contracts;
• Wind Generators;
• Operation and Maintenance (O&M);
• Life Cycle Services.
IMPSA ENERGY
• Investment projects for power generation from renewable
resources under the most modern project finance schemes like
BOT (Build, Operate & Transfer), BOO (Build, Own & Operate),
BROT (Build, Rehab, Operate & Transfer), BOM (Build Operation
& Maintenance) and PPP (Public-Private Partnership).
Current Hydro Projects
IMPSA is currently providing core equipment for several
hydroelectric power plants such as Bakun in Malaysia, Manuel Piar
(Tocoma) and Macagua I in Venezuela, Porce III in Colombia,
Acaray in Paraguay and Simplicio, Anta and Dardanelos in Brazil.
At the same time, the company is developing wind farms in Brazil
and Argentina for over 350 MW. IMPSA’s present power generation
projects add up to almost 6,500 MW.
Bakun, Malaysia - Highest efficiency: The project is one of the
l
argest developing projects being carried out in Southeast Asia.
Once operational, the Bakun project will be the main energy
generation source for current and projected local energy needs.
The Bakun dam will be a concrete face rock fill (“CFRF”) design
and, at 205 meters in height and 740 meters in length, will be one
of the highest dams in the world. When finished, Bakun HEP will
have a total installed capacity of 2,400MW from eight turbines.
I
MPSA signed a contract for the design, manufacturing, installation
and commissioning of four of the eight Francis turbines and
associated generators for the project. The equipment supplied by
IMPSA has a rated power of 335 MW and a maximum power of
340 MW, higher than requested by the customer (315 MW).
Tocoma, Venezuela - Largest Kaplan in the world: The project,
located in the Guayana region of Venezuela, is being undertaken
pursuant to a contract with EDELCA. IMPSA will supply the
electromechanical equipment for the 2,230 MW power plant.
The tender process began in 2004 with the participation of the
world’s leading suppliers of hydropower equipment. The client
required that the scale model be submitted with the technical
proposal envelope for testing at the independent hydraulic
laboratory of the École Polytechnique Fédérale in Lausanne,
Switzerland. This prestigious institution determined that IMPSA’s

With today’s emphasis on green and renewable energy, new
opportunities abound for not only development of new
hydroelectric projects but also for upgrading and making existing
hydroelectric facilities more efficient and cost effective.
Obermeyer Hydro, Inc. congratulates International Water Power
and Dam Construction Magazine on its 60th anniversary and
commends the editorial staff for bringing the world the latest
news from the Hydroelectric Industry and for promoting one of the
most green and renewable forms of energy available.
Like International Water Power and Dam Construction
Magazine, Obermeyer Hydro, Inc. is working to provide an energy
starved world with green renewable energy generated from water.
Obermeyer Pneumatic Water Control Gates are being installed at
new and existing hydroelectric projects around the world.
Obermeyer gate solutions provide economic and robust spillway
control and river diversion for large and small hydroelectric
projects alike.
Obermeyer Gate – Ashlu Creek
In western Canada, Obermeyer Gates provide water diversion
and control at the intake of the new Ashlu Creek Project.
Developed by Innergex Renewable Energy, Inc., this 49.9 Mw
power plant will produce approximately 265,000 Mwh of
electricity each year. This is enough green renewable energy to
power 23,000 homes per year while displacing 219,000 tons of
carbon dioxide that would otherwise be produced by a similar
sized coal fired plant.
The 4.5-meter by 35-meter long Obermeyer Gate at Ashlu Creek
consists of five sets of 7-meter wide inflatable air bladders and
gate panels. The gate is divided into two independently operable
zones of 7-meters and 28-meters. The use of dual chamber
inflatable air bladders reduces operating pressure and the forces
imparted by the gate into the concrete support structure.
Obermeyer Gate- Hound Chute
In Eastern Canada, the Providence of Ontario is striving to
eliminate its dependence on coal which currently provides 18%-
20% of Ontario’s energy needs. In response to that call, Ontario
Power Generation recently decided to upgrade plant capacity at
four of its existing hydroelectric facilities from 22 Mw to 44 Mw.
At the Hound Chute Project, two, 1.8-meter high by 30.5-meter
long Obermeyer Gates have been installed to help increase
generation from 3.6 Mw to 9.5 Mw.
The Hound Chute Project is noted for its extreme winter
conditions. Night time temperatures of -40 degrees C were
encountered during gate installation in January and February of
2009. The Obermeyer Gates at this location were designed with
heated abutment plates, an upstream aeration system for ice
control, and UHMW polyethylene skinned gate panels. These
design features were incorporated to enhance and promote
winter operation.
Obermeyer Gate – Lakatnik
Obermeyer Hydro is also providing equipment and design
expertise in the European hydroelectric market. In Bulgaria,
Obermeyer equipment has been successfully utilized at the
Lakatnik and Svragen Projects. These two hydroelectric projects
are the first of a series of nine projects currently envisioned on
the Iskar River north of Sofia. Developed by Petrovilla Group and
VezSvoge these projects will provide a new source of clean
electricity that will help promote the economy of an up and
coming member of the EU Community.
The Lakatnik and Svragen Projects each utilize two, 6.5-meter
high by 10-meter long spillway gates. The gates provide
accurate upstream water level control and create the upstream
pool at each of these run-of-the-river locations. The gates at
these projects represent the tallest Obermeyer Gates currently
installed in Europe.
Special thanks to Innergex Renewable Energy, Inc, Ontario
Power Generation, Petrovilla Group and VezSvoge.
