Alstom originally signed a deal to provide 19 bulb turbines (pictured) for the plant in 2008 and this week’s contract will see it supply two more bulb turbines, four generators, two speed governors, two excitation systems and six bus bars.
IMMA, a joint venture of Alstom and Brazilian engineering company Bardella, will also be responsible for all hydromechanical and lifting equipment.
So far around 40 per cent of the original contract is complete and operational. Santo Antonio is located in north Brazil’s Madeira River and is considered one of the largest hydro plants in the country.
Once installed, Alstom says the new equipment will boost power production by 417 MW, taking the total capacity to 3568 MW.
