9 December 2002 – Alstom has signed an agreement with hydro-turbine manufacturer Waplans for co-operation on the Swedish hydro market.
The agreement gives Alstom a partner with modern, local Swedish workshops and Waplans access to Alstom’s international turbine technology and laboratory resources.
It will thus enable the two companies jointly to offer complete solutions for Swedish power producers’ requirements for electrical and mechanical equipment.
Specifically, Waplans will have access to Alstom’s hydraulic calculation capability and advanced laboratories for model turbine tests. Waplans will manufacture and supply turbine components, other mechanical equipment and hydraulic systems, backed by Alstom’s manufacturing capability for certain components. In joint offers of complete mechanical and electrical solutions, Alstom will supply electrical equipment such as new generators and generator equipment, control equipment, instrumentation and other electrical equipment for hydro power stations.
Separately, ALSTOM has signed a contract valued at €40m with Hidroelectrica De Cahora Bassa SA (HCB), for the complete refurbishment of the Cahora Bassa hydro power station (5 x 415 MW), located on the Zambezi river near Songo in the Tete province of Mozambique.
The turnkey contract covers the rehabilitation of turbine, generator, electrical balance of plant, hydro-mechanical equipment and supply of control systems for two central control operator stations, as well as training of local staff. This comprehensive modernization and automation programme is needed to meet increasing electricity demands in the region.
The project will be managed by Alstom’s Hydro division in France, equipment and components being supplied from the Company’s manufacturing facilities in Grenoble and Belfort, France, and in Lisbon, Portugal. The engineering work has already started and site work is expected to begin in April 2003. The first unit is scheduled for commissioning in October 2003 and the final unit in June 2004.
The Cahora Bassa plant was commissioned in the late seventies. Like many aging hydro power plants, it is often prevented from operating with optimal performance by problems related to maintenance and supply of spare parts. The refurbishment, in particular the modernization of the control system, will allow HCB to run the plant at full capacity without impacting the environment.
