Yokogawa Australia Pty. Ltd., a wholly owned subsidiary of Yokogawa Electric Corp. (www.yokogawa.com), received a contract in April for a control systems replacement project at the Loy Yang A coal-fired power station in Australia. According to terms of the deal, the contract is estimated to be worth approximately 30 million Australian dollars.

The Loy Yang A coal-fired power station is the largest thermal power station in the state of Victoria. It went into operation in 1984. The total power output of the station is 2200MW (550MW of electricity output by each of the station’s four power generators). To address the aging of the control systems and ensure the long-term stability of station operation, Yokogawa will replace the control systems for the whole station, including the power generation, station common plant, and coal transportation facilities between October 2007 and June 2014.

Yokogawa will provide Loy Yang Power with an integrated production control system (CENTUM CS 3000 R3), a network-based control system (STARDOM), a safety instrumented system (ProSafe-RS), a plant information management system (Exaquantum), and other package software, plus engineering for these systems. A power plant training simulator from TechComm Simulation Pty. Ltd., a wholly owned Yokogawa subsidiary in Australia, will also be provided.
