Zurich, Switzerland — ESI-AFRICA.COM — 30 November 2010 – Leading Swiss-based power and automation technology group ABB has won an order worth US$43 million (R301 million) from South African electric utility ESKOM to supply medium-voltage switchgear, as well as protection and SCADA (supervisory control and data acquisition) equipment, for a new thermal power plant being built in Mpumalanga.
The new Kusile coal-fired plant is being constructed to increase power generation capacity in the country. It comprises six supercritical combustion units with a total generating capacity of 4 800 megawatts (MW).
A statement released here said ABB would design, engineer, supply, install and commission the equipment. Key products included the ZS1 AIS (air insulated switchgear) indoor switchgear for primary distribution, the latest Relion® range of control products and the REA range of protection relays. ABB would also supply a Micro-SCADA automation solution to optimise control and ensure reliable operation.
“These state-of-the-art products offer maximum control and protection, enabling an efficient and reliable supply of electricity,” said Bernhard Jucker, head of ABB’s Power Products division. “We support Eskom in its efforts to improve power supplies and meet the growing need for electricity in the country,” he added.
“With ABB’s tailor-made solutions, we are well positioned to contribute cutting-edge technology to South Africa’s major energy challenges,” said ABB South Africa CEO Carlos Poñe. “The Kusile project will generate cost effective electricity into the South African grid and will help meet the growing demand for electricity in South Africa.”
REA is an extremely fast and reliable arc protection system developed by ABB. It combines a unique sensor technique with instantaneous and reliable fault detection, reducing the risk of network damage, enhancing safety, and enabling the smooth restoration of power in the event of a disruption.
ABB’s recently introduced Relion® portfolio protects, monitors and controls power systems in a wide range of applications and voltage levels, from basic distribution to high-end transmission. It is compliant with the global IEC 61850 standard for substation automation, which facilitates seamless, real-time communication with other IEC 61850 compliant intelligent electronic devices (IEDs), tools and systems, regardless of manufacturer.
