Alstom to refurbish DR Congo’s 260-MW Nseke, Angola’s 260-MW Cambambe

Alstom Hydro announced it signed two contracts totaling 50 million euros (US$68.2 million) for rehabilitation of the 260-MW Nseke hydroelectric project in the Democratic Republic of Congo (DRC) and the 260-MW Cambambe hydro project in Angola.

Alstom Hydro, a joint venture of Alstom and Bouygues of France, said the 1950s-vintage hydro plants have been operating at reduced capacities due to deterioration during past regional unrest. The contracts call for Alstom Hydro to restore Nseke to its original operating condition and to substantially increase Cambambe’s power output.

Alstom Hydro’s service operation in Grenoble, France, is in charge of refurbishing Nseke (or Seke) on the Lualaba River for DRC utility Societe Nationale d’Electricite. (HNN 12/21/07) The contract includes rehabilitation of four 65-MW turbine-generators and balance of plant as well as supply of hydro-mechanical equipment, mostly manufactured at Grenoble and at Alstom facilities in Birr, Switzerland. Commercial operation of the refurbished plant is set for January 2010.

As part of a consortium with Brazilian builder Odebrecht, Alstom Hydro’s Brazil unit is to rehabilitate Cambambe on the Kwanza River for Angola utility Empresa Nacional de Electricidade. (HNN 6/14/07) The scope of work includes supply, installation supervision, and commissioning of four 72-megavolt-ampere generators; supply and integration of new digital protection and control systems; and supply of hydro-mechanical and lifting equipment.

Equipment for Cambambe is to be manufactured at Alstom facilities in Taubate, Brazil. The first unit is to begin operation in September 2009, with the last going on line in June 2010.
