The Callide Unit B1 HP turbine rotor was the focus of recent shutdown work.

CS Energy plans to spend $71.4 million on overhaul projects at its power stations across Queensland this financial year.

CS Energy chief executive officer Martin Moore said this budgeted expenditure reflected the company’s commitment to the safe, reliable and efficient operation of its power stations.

“This financial year, there will be four overhauls across our generation portfolio to keep our power stations operating in peak condition into the future,” he said.

The first of the maintenance shutdowns was a mini-overhaul completed recently on generating Unit B1 at the coal-fired Callide Power Station near Biloela, bringing more than 130 extra workers on site.

Mitsubishi Hitachi Power Systems was the major contractor for the $12.1 million overhaul, with additional contractors such as Central Queensland Inspection Services (CQIS) used for specialised work.

“The Callide Unit B1 overhaul included inspections and tests on a range of plant such as the high pressure turbine generator, air heaters, boiler and control system,” Mr Moore said.

“We’re now focussing on an overhaul of Unit W2 at our pumped storage hydro Wivenhoe Power Station that is under way until mid-October, followed by an overhaul of Unit B2 at Callide later that month.

“Our biggest overhaul for this financial year is a major overhaul of Kogan Creek Power Station in April 2016, which involves the replacement of the high pressure turbine and will employ up to 480 additional workers at site.”

Mitsubishi Hitachi Power Systems is the major contractor for the Wivenhoe shutdown and Siemens has been named as one of two principal contractors for the Kogan Creek work.

Mr Moore said every overhaul represented an injection into the local economies surrounding CS Energy’s power stations.

“Our site workforces grow by the hundreds during each overhaul, providing short-term employment opportunities for people with the skills and expertise required to undertake the maintenance and upgrades to the power station equipment,” he said.
