Eskom electrical grid wobbles as four generation units trip

Eskom issued a power alert on social media on Wednesday evening 29 July 2020, followed about a notice to reduce electricity consumption after four generation units were lost.

The power utility urged residents to switch off all non-essential appliances and warned that the generation system is severely constrained. Here's what we know.

Eskom power alert 29 July 2020

The power utility confirmed that four generation units were lost at the Tutuka, Kusile and Medupi power stations following "breakdowns over the past few days, which has added to the capacity constraints".

"These constraints have been exacerbated by the unavailability of three non-commercial units at Kusile and Medupi power stations, as well as long-term outages at the Camden power station".

Eskom didn't share any other details, apart from saying that maintenance teams "are hard to work to return these units to service", and that capacity constraints "are expected to persist for the rest of the week".

"Eskom requests your assistance in reducing demand so we may be able to supply the country through the peak demand period in the evenings".

Load reduction and power outages in three provinces

This follows after a number of alerts were issued during July pertaining to load reduction and power cuts in Gauteng, KwaZulu-Natal and Mpumalanga.

Eskom also warned earlier today that several suburbs would be experience blackouts between 17:00 and 21:00, including Buffelspruit, Nkomazi, Kanyamazane and Matsulu in Mpumalanga.

In Gauteng, outages can be expected in Soweto, Vaal and the West Rand, while KwaZulu-Natal residents in Msunduzi, Newcastle, Dannhauser and Emandangeni would experience outages too.

Eskom calls on residents to refrain from logging faults during this period, and to treat all outlets as live.

Eskom urges customers to treat all installations as live. […] During the load reduction implementation, customers are urged to switch off all their electrical appliances to avoid power surges when power returns.

Failure to do so may lead to transformer trips or failures, and damages to household appliances when supply is restored.
