An updated version of the load shedding code of practice has been finalized by an expert group and submitted to the National Energy Regulator of South Africa (Nersa) for approval. The revised edition, known as Edition 3, includes protocols for up to 16 stages of load shedding, with the highest stage involving 24 hours of load shedding in a 32-hour cycle. The current Edition 2 only covers up to eight stages of load shedding.

The new code has been developed by the National Rationalised Specifications Association of South Africa (NRS Association), a voluntary forum consisting of representatives from Eskom, the country's metros, municipalities, the South African Bureau of Standards, and Nersa. While the document has not been made public, it is expected to be released by Nersa during a public consultation process.

It is important to note that the introduction of Edition 3 does not imply that Stage 16 load shedding is imminent. Instead, the updated protocols aim to enhance preparedness among the individuals responsible for grid stability across the national and municipal systems. The goal is to prevent a national blackout by providing clear guidelines and mitigating the potential for human error.

According to Vally Padayachee, the chairperson of the NRS Association, the increase in the number of stages is intended to address the reliance on "contingency measures" once Stage 8 is breached under the current protocols. The updated code will help system operators take appropriate actions to maintain grid stability. While Eskom's performance has improved recently, the risk of load shedding remains, especially during cold weather periods.

Eskom had previously warned of the possibility of Stage 8 load shedding during winter. However, lower-than-expected demand and improved performance from some coal stations have allowed the utility to reduce the severity of load shedding in recent weeks. The Electricity Minister, Dr. Kgosientsho Ramokgopa, has noted a positive trend in breakdowns within the coal fleet, bringing load shedding and diesel usage closer to more manageable levels.

Although demand has been lower than forecasted, the new load shedding code of practice is expected to enhance resilience by providing clear instructions to system operators, who have been operating under challenging conditions. It outlines the necessary actions to prevent a complete grid collapse.
