What is expected to be the largest and most sophisticated power station, at a mine in Angola has been commissioned after an extensive overhaul undertaken by Barloworld Equipamentos – Angola. Planned expansion of production at the Catoca diamond mine, in Angola, has necessitated the increase of the power station’s capacity from 12 MW to 24 MW and Barloworld Equipamentos – Angola, which developed the original power station at the mine, commissioned the upgraded facility in August 2005.

The Barloworld division undertook the turnkey project in May 2004 when the client, Sociedade Mineira de Catoca, gave the green light for the US$6 million upgrade of the existing power station, the construction of a second power station and the integration of the two into a state-of-the-art control centre.

Barloworld Equipamentos – Angola has been involved with the Angolan diamond mine since 1996 when it supplied four CAT3516 1,360 kW diesel driven generator sets for Catoca’s first power station. The Caterpillar distributor and turnkey power station developer has since supplied another four 1,460 kW generator sets to provide sufficient power to cater for incremental growth at the mine.

Drawing on skills and services from three other South African companies, the Barloword team created a power station that is not only capable of meeting the predicted power requirements for Catoca but one which can be upgraded to accommodate further growth at the mine, which has a predicted 35 year life-of-mine and reserves of an estimated 60 million carats.

In addition to supplying eight new CAT3516 1,460 kW diesel driven generator sets and medium voltage switchgear, the Barloworld division has reconfigured the old power station to integrate it with sophisticated programmable logic control (PLC) technology that will control and monitor both power stations.
