Yokogawa Receives Control Systems Contract for Large Coal-fired Power Station in South Africa

Tokyo, Japan - June 30, 2011

Yokogawa Electric Corporation announces that its subsidiary Yokogawa South Africa (Pty.) Ltd. has received a contract from Eskom*, a South African public power utility, to supply control systems and instrumentation for the Outside Plant and Water Treatment Plant at Tutuka Power Station.
While Eskom has purchased more than 3,000 pressure/differential pressure transmitters from Yokogawa to date, this is their first control systems order with us.

Tutuka Power Station is located approximately 200 Km Southeast of Johannesburg, near the town of Standerton, and began commercial operation in 1985. With six 609 MW units that have a combined generating capacity of 3,654 MW, it is one of the largest coal-fired power plants in South Africa.
This contract is for a large-scale project to replace ageing transmitters and other field instruments as well as the aforementioned supply of control systems for the auxiliary facilities that are used by all the generating units. Project completion is scheduled for June 2013.

For this project, Yokogawa will supply CENTUM® VP series integrated production control systems, the PRM® integrated device management package for monitoring and diagnosis of plant equipment, Exaquantum® plant information management systems, and DPharp™ series pressure/differential pressure transmitters. Yokogawa South Africa will undertake this project wholly, including delivery, engineering, installation, commissioning and handing over to Eskom the fully functional plant.

Yokogawa was able to win this order as a result of high acclaim for the Yokogawa pressure/differential pressure transmitters already delivered to Eskom and Yokogawa South Africa's excellent engineering and process knowledge capability and customer-centric services. At the contract signing ceremony, Ryno Lacock, Tutuka Power Station Manager said: "We are looking forward to improved plant operational efficiency with the latest control technology and technical support from Yokogawa."

In South Africa, the continuous development of the industrial sector is quickening the pace of foreign trade and industrial activity and the increase in demand for electricity is outstripping supply. Construction and renewal of power facilities to overcome the electricity shortage are in progress under a plan to increase the nation's electricity capacity to 90 GW, which is double today's capacity, by 2030.
Encouraged by winning this order, Yokogawa aims to expand its power business in South Africa and to contribute to a stable supply of electricity for Africa.

* Eskom
Established in 1923, Eskom is one of the largest electricity producers in the world in terms of generation capacity and sales. Eskom generates approximately 95% of the electricity in South Africa and approximately 45% of the electricity in Africa.
