Under the terms of the contract, alstom will design, manufacture and deliver four new 333MW Francis turbine runners for units 1-4 of the dam, and carry out the complete refurbishment and modernisation of two turbine-generator groups. The company will also supply several new components (ring gate, distributor, servomotors and turbine shaft) for unit 1 of the power plant, while refurbishing some of the existing components for units 2 and 3, and replacing 16 electronic governor systems.
