While South Africa has enjoyed an extended respite from load shedding this year, there are other compelling reasons to accelerate the transition to renewable energy:

• Businesses and homeowners are concerned about Eskom’s reported intention of seeking a 36% increase in tariffs in 2025 – on the back of electricity prices that have roughly tripled over the past 14 years.
• The future reliability of our electricity system remains uncertain. Recent reports indicate that load reduction is frustrating communities, particularly in Gauteng.
• It is forecast that more than three million green jobs could be directly created in Africa by 2030, mostly in renewable energy and, particularly, solar. At the same time, independent power producers must be committed to the Just Energy Transition in South Africa, in partnership with government and industry. We are mindful that the broader energy shift must work in tandem with a sustainable employment framework – especially in a country with such high unemployment levels.

Consensus on the value of sustainable power for Africa

In June, more than 2,000 stakeholders gathered at the annual Africa Energy Forum in Barcelona. The prevailing consensus among attendees was that the continent’s move towards sustainable energy presents immense opportunities.

During a panel hosted by the International Finance Corporation (IFC), I emphasised that sustainability is integral to the energy sector. South Africa holds tremendous potential for renewable energy and distributed or decentralised generation is a viable solution for delivery in the short term, while Eskom and all industry stakeholders co-operate to solve the longstanding grid crisis.

South Africa has the largest installed capacity in Africa at c.60GW and replacing the older, coal-fired Eskom fleet would require a huge annual replacement energy investment  – in which renewables should play a major role.

The growing affordability of BESS and Solar

Battery Energy Storage Systems (BESS) is now becoming more economically viable for South African business owners, who can combine this rapidly evolving technology with solar and diesel generators to escape the impact of escalating grid power prices. Accelerating innovation in BESS will bring reliable electricity to many businesses in the next few years.

Wind power generation has had mixed operational performance given climate change and, with BESS becoming increasingly more affordable, an integrated solution of solar and BESS is proving to be an ideal and environmentally friendly solution.

Whilst it represents a capital expense, parties undertake this expense, leaving industry players free to sign up power purchase agreements (PPAs) to secure their power requirements without needing to use their capex budgets.

The rising popularity of PPA

In a PPA, an independent power producer (IPP) provides the financing for engineering, construction, procurement and operations and maintenance (O&M).

Data shows that an IPP-owned and operated solar power plant typically performs better than those that are funded and operated by offtakers, whose core business is not energy generation.

The cost savings are substantial as well. Assuming an ESKOM blended tariff of R1.65/kWh, a solar PPA typically provides savings of 20 – 30% on electricity bills. This percentage varies and can increase significantly for large-scale on-site and solar wheeling projects.

The role of the private sector

The resourceful private sector has already been swift in securing on-site solar power, BESS and generators, as shown by SAPVIA’s statistics on South Africa’s accelerated solar adoption.

Large energy users are now seeing the benefits of solar wheeling and behind-the- meter (BTM) solutions. On the broader scale, the government has highlighted the role of public-private sector partnerships in strengthening South Africa’s economic future; we should see them being a priority within the energy sector.

Related FAQs: Sustainable energy independence solutions

Q: What are some sustainable energy solutions to achieve energy independence after load shedding?

A: Sustainable energy solutions to achieve energy independence include the use of solar panels, wind power and energy storage solutions. These technologies allow individuals and communities to generate their own clean energy and reduce reliance on traditional energy sources.

Q: How can solar power contribute to a sustainable energy future?

A: Solar power contributes to a sustainable energy future by providing a renewable energy source that reduces greenhouse gas emissions. The use of solar panels can help meet energy demand while promoting energy efficiency and lowering energy costs.

Q: What are the benefits of sustainable energy in terms of energy security?

A: The benefits of sustainable energy include increased energy security by diversifying energy sources, reducing dependency on fossil fuels and enhancing resilience against energy supply disruptions. This leads to a more stable and reliable energy system.

Q: Can wind power play a significant role in energy independence?

A: Yes, wind power can play a significant role in energy independence by providing an abundant renewable resource. By harnessing wind energy, communities can reduce their reliance on external energy supplies and contribute to a zero-carbon energy future.

Q: What are some effective energy management strategies for achieving energy independence?

A: Effective energy management strategies include optimising energy consumption, investing in energy efficiency technologies, and utilising energy storage solutions to balance supply and demand. These practices help maximise the benefits of renewable energy sources.

Q: How can individuals utilise renewable resources to achieve energy independence?

A: Individuals can utilise renewable resources such as solar and wind energy to achieve energy independence by installing solar panels and wind turbines. This allows them to generate their own electrical energy and decrease their reliance on the energy grid.

Q: What role do energy storage solutions play in a resilient energy future?

A: Energy storage solutions are crucial for a resilient energy future as they allow for the storage of excess energy produced during peak times. This stored energy can be used during periods of high demand or when renewable energy generation is low, ensuring a consistent energy supply.

Q: How does using renewable energy contribute to a sustainable future?

A: Using renewable energy contributes to a sustainable future by reducing carbon emissions, decreasing dependence on finite resources and promoting a healthier environment. It also fosters energy independence and security, leading to a more stable energy landscape.

Q: What are the implications of energy independence for the global energy landscape?

A: Energy independence has significant implications for the global energy landscape by shifting the focus towards local and renewable energy sources. This transition can enhance energy security on a global scale and promote the development of sustainable energy solutions worldwide.

Q: How can governments support the transition to sustainable energy solutions?

A: Governments can support the transition to sustainable energy solutions by implementing policies that incentivise the use of renewable resources, investing in clean energy infrastructure and promoting research and development in energy technologies that enhance energy independence and security.
