Loadshedding

Loadshedding is the deliberate and controlled interruption of electricity supply to parts of a distribution network to prevent the collapse of the entire power system when demand exceeds available generation capacity. The practice is implemented by utilities and grid operators when power stations cannot produce enough electricity to meet consumption, typically due to plant breakdowns, maintenance backlogs, fuel shortages or insufficient generation capacity. Loadshedding is usually executed in rotating blocks or stages, with different areas experiencing outages at scheduled times to distribute the impact across the customer base. In South Africa, the term has become synonymous with the country's prolonged electricity crisis, where state utility Eskom has implemented recurring loadshedding since 2007, with intensity escalating significantly from 2019 onwards. The practice is categorised into stages, typically ranging from Stage 1 to Stage 6 or higher, with each stage representing an incremental reduction in available power and longer or more frequent outages. Loadshedding has profound economic consequences, disrupting manufacturing, mining, commerce and daily life, while driving increased adoption of backup power solutions such as diesel generators, battery storage and solar photovoltaic systems. Businesses and households have responded by investing in uninterruptible power supplies, inverters and renewable energy installations to mitigate the impact of supply interruptions. The phenomenon has also accelerated interest in energy efficiency, demand-side management and distributed generation as strategies to reduce reliance on the national grid. Loadshedding remains a critical challenge for economic growth and energy security in affected markets, prompting policy reforms and infrastructure investment to address underlying generation deficits.

POWER POSER: The Hillside Aluminium smelter in KwaZulu-Natal marked its thirtieth anniversary this month, while indicating that it is seeking another competitive long-term electricity agreement to sustain operations. Hillside’s current negotiated pricing agreement has been key to the business, but has also proved controversial for its opacity and for having been sustained while other consumers faced steep hikes and power cuts. As with other electricity intensive operations in South Africa, Hillside wants both a low tariff and progressively cleaner supply.
