Alstom-Voith-VA Tech group to equip Brazil’s 3,300-MW Jirau

A consortium led by Alstom Hydro and including Voith Siemens Hydro Power Generation and Andritz VA Tech Hydro has won a contract to supply turbine-generators and other equipment for the 3,300-MW Jirau hydroelectric project on the Madeira River in Brazil’s Rondonia State.

Alstom Hydro said the 300 million euro (US$421.8 million) contract was signed between the three hydro equipment manufacturers and Consorcio Energia Sustentavel do Brasil (Enersus), winner of a concession to build Jirau in Brazil’s Amazon Region.

Enersus members include Suez Energy South America Participacoes Ltda.; Eletrosul Centrais Eletricas S/A; Companhia Hidro Eletrica do Sao Francisco (CHESF); and Camargo Correa Investimentos em Infra-Estrutura S/A. (HNN 12/8/08)

Alstom Hydro said the manufacturer consortium is to design, manufacture, and supply 28 75-MW bulb-turbine generating units designed for lower water head and reduced environmental effects. Alstom said it is responsible for 48 percent of the contract, including 10 turbines, 17 generators, 28 governors, monitoring systems, bus bars and surge/neutral devices.

The contract also includes installation and commissioning. Alstom said most of the equipment will be produced in Brazil, notably the turbines and generators manufactured at Alstom’s Taubate factory.

Alstom Hydro announced in September it received a 500 million euro (US$708 million) contract to supply electro-mechanical and hydro-mechanical equipment to Jirau’s sister project on the Madeira, 3,150-MW Santo Antonio. Andritz VA Tech Hydro announced in December it also received a 250 million euro (US$317.2 million) contract to supply turbine-generators and voltage regulating systems for Santo Antonio.

The Jirau and Santo Antonio dams were planned to be built 84 kilometers and 119 kilometers from the Bolivian border on the Madeira, an Amazon River tributary. The two hydro projects, with 44 turbines each, have an estimated cost of 22 billion reais (US$11.6 billion). Both now are expected to go on line in 2012.

An appellate judge in Brasilia overturned an injunction in December that had suspended an initial environmental license for construction of Jirau. The ruling backed plans by Enersus to move the Jirau dam nine kilometers downriver as a way to save 1 billion reais (US$626 million).
