Swiss group ABB has been awarded a contract of US$50 million from the Cahora Bassa Hydroelectric Facility (HCB) to renew the Songo high-voltage direct current (HVDC) converter station, the group said in a statement issued in Zurich Monday.
The converter station and associated equipment are key to the transmission of 1,920 megawatts of power generated at the hydroelectric plant to the power grid in South Africa, where most electricity is produced by burning coal.
According to the statement from ABB, the refurbishment of the station will ensure the system is more reliable, allowing the Cahora Bassa Hydroelectric Facility to comply with the power purchase agreement signed with South African state company Eskom.
The Swiss group will also install additional equipment as part of this turn-key contract, which is for two years, with direct current equipment due to be installed in 2013 and the transformers a year later. (macauhub)
