CURRENT PROJECTS
Rehabilitations of Hydroelectric Power
Plants
The
scope of supply
of the project is the complete rehabilitation of two hydroelectric
power plants. Each power plant consists of 2 Francis Turbines groups
(25MW each turbine). The total electric power generation of the system
is 100 MW. The project involves intervention for rehabilitation of the
turbines, the generators, the electric systems of automation and
control, the electric systems of substation and the systems of data
transmission and communication, with the objective to extend its useful
life for another additional 25 years. The main technical data of the
installed machines are:

The
rehabilitation of
the power plants will drive some key advantages.The substitution of the
electric and electronic systems will involve the possibility to operate
with greater values of general efficiency, optimizing the water flow
and operations. Moreover the substitution of the systems will allow to
use a renewable technology according to sustainable use of the water
resources of the basins. The project will probably allow to access the
market of the green certificates (CER's) for the sale of the missed CO2
certificates.
