17 September 2008 – Alstom Hydro has been awarded a major contract, valued at €500m ($711m), for the supply of electro-mechanical and hydro-mechanical equipment for the Santo Antônio hydropower plant in Brazil.
The contract was signed with Construtora Norberto Odebrecht, the EPC (engineering, procurement, construction) consortium leader of the Santo Antonio plant. The plant is scheduled to start commercial operation by mid 2012.
The Santo Antônio plant will be built on the Madeira river in the country’s northwest State of Rondônia, with an installed capacity of 3150 MW. It will comprise 44 bulb type generating units, of which Alstom Hydro will provide 19 bulb turbines and 22 generators as well as 50 per cent of the project’s hydro-mechanical and lifting equipment.
Bulb units are especially suitable for low head and run-of-river hydropower schemes such as Santo Antônio. These units are highly efficient as they are fully submerged in the water and thus able to handle significant variations in water discharge, as is the case for the Amazon region.
Alstom Hydro will manufacture the turbines and generators at its facility in Taubaté, Brazil, one of the company’s largest hydro industrial hubs worldwide.
The hydro-mechanical and lifting equipment will be supplied from a new factory currently being built in Porto Velho, Rondônia, by Indústria Metalúrgica e Mecânica da Amazônia (IMMA), a joint-venture by Alstom Hydro and Bardella, a Brazilian capital goods company. The plant, mainly dedicated to the projects in the Amazon region, is expected to be operational at the end of 2009 and will employ approximately 300 people.
