CS Energy Readies for Capital, Maintenance Projects at Coal-Fired Power Plants in Australia

---

Researched by Industrial Info Resources Australia (Perth, Australia)--CS Energy Limited (Brisbane, Australia), the state-owned power-generating company in Queensland, Australia plans to perform minor maintenance work at the Kogan Creek Power Station in Brigalow, Queensland, in November 2013.

The plant, commissioned in 2007, was built with high environmental performance standards. It has an advanced design that uses less water and produces lower environmental emissions than most other conventional-type, coal-fired power plants in Australia. The power station has a supercritical Babcock Hitachi boiler and a 750-megawatt (MW) Siemens steam turbine.

In 2012, CS Energy signed the integrated (frame) service agreement with Alstom Power Australia Pty Limited (Brisbane, Australia) and Clyde Babcock-Hitachi (Australia) Pty Limited (Brisbane) to provide maintenance services and upgrades for Kogan Creek Power Station, as well as for CS Energy's four other coal-fired generating units operating in Australia. The agreement with Alstom is valid for five years and is valued at approximately $130 million.

Around the fourth quarter of 2013, a two-week minor boiler and turbine inspection is scheduled to be performed on the Kogan Creek Unit 1. CS Energy undertakes such an outage on the whole unit every two years at the plant.

A major, 30-day outage on the same unit will begin in the third quarter of 2015, which is usually done once in every four years.

CS Energy operates Callide B & Callide C, along with Kogan Creek Power Station in Queensland. Callide B runs on two 350-MW Hitachi reheat condensing steam turbines and associated boilers. There will be a major, 21-day maintenance outage on these two units in 2014 and 2015, respectively.

CS Energy's Callide A was commissioned in 1965 in central Queensland with four 30-MW steam turbines. All the units were refurbished in 1998. In 2001, the company put the units in "storage," preparing for its conversion to Oxyfuel technology.

In December 2012, CS Energy launched the world's first oxyfuel carbon capture technology demonstration project on the Callide A 30-MW unit that is designed to capture 70 tons per day of CO2. The project will be tested for two years, and the conclusion of the demonstration will determine the commercialization plans. The total estimated cost for the project is approximately $206 million, and it is partly funded by the Australian government.

Oxyfuel technology is a groundbreaking technology that captures CO2 from coal-fired power plants and stores it deep beneath the earth. The company aims to reduce global warming by adapting the existing coal-fired power stations to produce almost zero-emission electricity using Oxyfuel.
