We supervised the testing and commissioning, energizing, and handing-over of:
-The dam at its new elevation
-The rehabilitated/new hydro ancillaries
-4 x 65 MW turbine generation units
-13 single-phase 11/220 kV, 24-MVA step-up transformers
- A 220 kV switchgear bay.

We also ensured the upgrade of AC/DC auxiliary supplies and the installation of new 30 kV & 11 kV medium voltage switchgears; new 30/0.4 kV & 11/0.4 kV transformers; new control, metering, protection, communication, and SCADA Systems; new emergency diesel generators; new lighting system; and new A/C, ventilation and electromechanical systems.

We have, through the rehabilitation and upgrade, allowed the full utilization of the installed hydroelectric power plant.
