- A blast at the Devon Valley substation led to a widespread power interruption in Stellenbosch.
- Equipment, known as the Firgrove 132kV feeder white phase current transformer, exploded.
- Eskom said staff would be on site on Tuesday to assess the damage and do the necessary repairs.
Power was restored to central Stellenbosch and the surrounds in the early hours of Tuesday morning after a widespread electricity interruption on Monday night following a fire at the Devon Valley substation.
According to Eskom, the supply was interrupted at 21:50 following an explosion at the substation, affecting the municipality, Koelenhof, Cloetesville, Lynedoch, De Zalze, Kylemore and the neighbouring areas.
"The fire was caused by equipment which exploded, known as the Firgrove 132kV feeder white phase current transformer (CT),” the power utility said in a statement.
"The fire brigade and Eskom technicians were dispatched to site. The technicians safeguarded the equipment and restored supply to the customers."
Staff would be on site on Tuesday to assess the damage and do the necessary repairs.
Stellenbosch Municipality spokesperson Stuart Grobbelaar said the fire had been quickly extinguished by the local fire services.
"Power was fully restored at around 00:15 [on Tuesday] morning. Central Stellenbosch (town) and surrounding suburbs were affected by this outage for approximately two and a half hours," he said.
Eskom on Monday night suspended load shedding after five days of rolling blackouts.
Initially only scheduled to last until Sunday, as some units supposed to return to service were delayed, Fin24 reported.
