Yokogawa Electric Corporation’s Australian subsidiary singed a contract with AGL Energy Limited (AGL, www.agl.com.au) to replace the control and instrumentation systems at Section B of the Torrens Island Power Station in Adelaide, South Australia. The contract is estimated to be worth $28 million.

The Torrens Island Power Station consists of Section A with four 120 MW units and Section B with four 200 MW units — a combined generating capacity of 1,280 MW. The facility is Australia’s largest natural gas-fired thermal power station, burning natural gas supplied from Victoria and the Cooper Basin.

AGL has initiated a program to replace the control and instrumentation systems for the turbines and boilers in each of Section B’s four units, and on some of the common plant facilities. The refurbishment of the first two units is scheduled to be completed in calendar year 2010 and is expected to enhance operations and ensure ongoing reliability of supply.

For this refurbishment project, known as “Project Gateway,” Yokogawa (www.yokogawa.com) is providing AGL with the CENTUM VP Integrated Production Control System, ProSafe-RS Safety Instrumented System, Exaquantum Plant Information Management System and other software packages, as well as a variety of transmitters including the DPharp EJX series of differential-pressure transmitters.

The project scope includes the detailed design, engineering, equipment supply, factory testing, installation, commissioning and performance testing of the control and instrumentation systems.
