Eskom was forced to evacuate staff after a major explosion at its Lethabo Power Station, near Viljoensdrif in the Free State, on Wednesday afternoon.

The utility confirmed that it is investigating what it called a “major incident” at unit five of the power station.

“We can confirm that there are injuries but cannot confirm further details at this stage. Management’s first priority is to ensure the safety of all staff on site‚” Eskom tweeted.

UPDATE

Boiler explosion

According to the utility the live steam pressure from the boiler of Unit 5 of the Lethabo Power Station ruptured, sending a plume of dust into the air.

Eskom management have visited the power station since last night, and a thorough investigation had been initiated as per regulatory requirements.

“Based on the preliminary investigation, it is expected that Unit 5 will remain out of service for a minimum of three months. The loss of Unit 5 will have a negative effect on the power system given that Lethabo Power Station is one of the most cost-effective generators with adequate access to a steady coal supply. All efforts will be focused on the safe and swift return of this unit to the national grid,” explained Eskom’s Group Chief Executive Phakamani Hadebe.

One employee killed

Unfortunately, one of Eskom’s employees lost his life on site, and another staff member was rushed to the local hospital.

Hadebe extended condolences to the family and friends of the deceased on behalf of the Eskom Board, executive management and all the Eskom employees.

“We would also like to wish the colleague who is in hospital a speedy recovery. Our thoughts and prayers are with the families, friends and immediate colleagues of the two affected employees during this difficult period,” he added.

All work at the power station has stopped and according to the utility and Employee Assistance Programme has been arranged to assist all employees with counseling. Counseling has also been arranged for family members of the two directly affected employees.
