Cape Town, South Africa — ESI-AFRICA.COM — 05 April 2011 – An investigation by national power utility Eskom Holdings Limited into the routine turbine test that went wrong at its Duvha power station in the Mpumalanga province earlier this year is still underway.

Revealing this in a written reply to a parliamentary question, public enterprises minister Malusi Gigabahe confirmed that there was "severe mechanical damage" to one of the coal-fired station’s six 600MW turbine units. The incident happened on 9 February.

“Unit 4 of Eskom’s Duvha power station was damaged in the course of a routine, scheduled turbine over-speed protection test. In the execution of the test, the protection on the unit failed, causing severe mechanical damage,” Gigaba explained.

At the time, Eskom spokesperson Hilary Joffe reportedly said it would take "many months" to repair the damage to the unit, but that the other five units of the 3 600MW Duvha plant were running normally.

Gigaba said a statement would be issued once the investigation had been completed. “The investigation is still underway and will cover an assessment of the damage, the cause thereof and the cost and time to repair,” he said.
