As of March 25, 2024, South Africa has gone six months without load shedding—a significant milestone for a country that has struggled with electricity supply issues since 2007. Load shedding, a planned power outage system, began as a measure to stabilize the electricity grid by reducing demand on strained infrastructure. However, in 2022, it is reported that the country is facing load shedding in nearly 300 days; in 2023, South Africa faced one of its most severe power shortages, with blackouts lasting up to half a day in some areas.

So, why has there been such a marked improvement in 2024, with six consecutive months free from load shedding? Here’s a closer look at the contributing factors:

1. Government and Eskom Initiatives:

Over the past two years, South Africa has launched several initiatives to address energy supply, such as appointing an Electricity Minister, providing financial assistance to Eskom, and implementing Eskom’s two-year Generation Operational Recovery Plan aimed at boosting energy production.

2. Eskom’s Internal Reforms:

Eskom has made structural and personnel changes to combat corruption and improve operational efficiency.

3. Reduced National Power Demand:

Rising electricity costs and an increase in private renewable energy installations have led to decreased demand, particularly as economic growth has slowed.

Yet, does this period without load shedding signal the end of South Africa’s electricity supply challenges?

The Path to True Stability is Uncertain

Despite these gains, energy stability remains uncertain. Occasional outages, known as "load reduction," still occur in certain areas. This targeted power reduction helps Eskom protect overloaded infrastructure, like transformers, and prevent prolonged blackouts. According to reports, about 5% of South African households are still impacted by load reduction.

Additionally, Eskom is pursuing further rate hikes. The utility has submitted a request to the National Energy Regulator of South Africa (Nersa) for incremental price increases: a 36.1% rise in 2025, followed by an 11.8% hike in 2026, and 9.1% in 2027. The final figures will be determined by Nersa, but rising electricity costs are expected to continue—a financial strain for households where power has become a luxury.

Adding to the complexity, South Africa’s energy infrastructure is aging and heavily reliant on coal, with only 5% of electricity currently derived from renewable sources in 2021. Dependence on coal-based energy means the nation is vulnerable to operational and environmental disruptions, including aging facilities, management issues, and unforeseen events like coal mine strikes, all of which threaten supply stability.

The Ultimate Solution: Embrace Energy Independence

For households and businesses, hoping for a continuous improvement in power reliability could be risky. Power is fundamental to everyday life and economic activity, and without it, homes face disruption and businesses grind to a halt. Energy independence through renewable solutions is increasingly essential.

Fortunately, many South Africans are embracing energy storage systems. According to a 2024 survey conducted by South Africa’s Power Transmission Company, the South African Photovoltaic Industry Association, and the South African Wind Energy Association, the nation’s renewable energy sector is growing significantly. In 2023, South Africa’s renewable energy capacity totaled 67GW; in 2024, it nearly doubled to 134GW, with project numbers rising from 209 to 483.

The financial benefits of solar storage systems over relying on Eskom are clear. According to MyBroadband’s analysis[1], assuming 90% self-generation and 10% grid usage, users—especially those with larger systems—can achieve significant monthly savings. With Eskom’s 36.15% rate increase, households or businesses consuming over 600 kWh per month can realize noticeable cost reductions by switching to solar storage. The takeaway is simple: as Eskom’s rates continue to rise, the savings from a solar system only grow.

For those seeking a secure, reliable energy solution, advanced storage systems like Sigenergy’s SigenStor are becoming an ideal choice.
