André de Ruyter, the former chief executive of South Africa's embattled state power utility Eskom, has outlined how Australia managed to bring down electricity prices and whether those lessons can be applied to Johannesburg and Cape Town. The recommendations come as South African households and industries face mounting electricity bills that economists link directly to the country's sluggish growth. de Ruyter shared his analysis during a public forum in Cape Town on Tuesday, drawing comparisons between the Australian National Electricity Market and South Africa's struggling system.
The Australian Model Explained
de Ruyter pointed to Australia as a rare example of electricity market reform that actually delivered lower prices for consumers. He identified three core features that drove Australia's success: reduced network costs through smarter regulation, lower coal prices as the generation mix shifted, and increased competition among generators. These factors combined allowed Australian households to pay roughly 40 per cent less for electricity than their South African counterparts, despite Australia having one of the highest renewable energy penetrations in the world. The former Eskom CEO stressed that market structure, not just the source of generation, determines what consumers ultimately pay.
Where South Africa Went Wrong
South Africa's electricity system remains dominated by Eskom, a utility that has accumulated debt exceeding 400 billion rand and imposed rolling blackouts across the country for years. de Ruyter served as Eskom's CEO until early 2024 and has since spoken candidly about the utility's structural problems. He argued that South Africa's high prices stem from bloated infrastructure costs passed on to consumers, an outdated tariff structure that rewards inefficiency, and a lack of genuine competition in the generation market. The result is a system where industrial users in Gauteng pay among the highest electricity tariffs globally, deterring new investment in manufacturing and mining.
Debt and Governance Failures
Eskom's balance sheet has been a drag on the national economy. The utility received multiple government bailouts totaling over 100 billion rand in the past decade, yet performance continued to deteriorate. de Ruyter highlighted that Australian regulators took a harder line on network companies, forcing them to cut costs rather than simply approving revenue increases. South Africa's energy regulator has faced criticism for lacking the independence or capacity to push similar reforms. The former CEO called for a fundamental rethink of how electricity tariffs are set, arguing that the current model shields Eskom from the pressure to become more efficient.
What Johannesburg and Cape Town Can Actually Do
de Ruyter acknowledged that transplanting the Australian model wholesale would not be straightforward. South Africa's coal dependency, Eskom's monopoly position, and the political sensitivity of electricity pricing all create obstacles that Australia never faced. However, he identified specific steps that South African policymakers could take immediately. One priority involves accelerating the procurement of new generation capacity from independent producers, a process that has been slow despite regulatory amendments designed to encourage private investment. Another involves restructuring Eskom's debt obligations so that the utility's legacy costs do not continue to inflate consumer tariffs indefinitely.
The Political Dimension
Electricity pricing in South Africa has always carried political weight. The African National Congress government has historically resisted significant reforms that could increase short-term electricity costs for low-income households, even if those reforms might lower prices over time. de Ruyter noted that Australian politicians faced similar resistance but ultimately managed to push through market changes because the economic case became impossible to ignore. In South Africa, the upcoming elections have made the government even more cautious about any policy that could be perceived as raising household costs. This political calculus has delayed structural reforms that economists say are essential for long-term price reduction.
Implications for African Development Goals
South Africa's electricity crisis is not merely a national problem. The country is the continent's most industrialised economy, and its energy trajectory affects regional supply chains, cross-border investment, and Africa's ability to meet development targets. Reliable and affordable electricity is foundational to achieving goals in health, education, and economic diversification across the continent. When South African manufacturers pay inflated electricity costs, goods become more expensive across southern Africa. When Eskom's load-shedding cuts power to mines and factories, workers in surrounding communities lose income. de Ruyter's analysis therefore carries implications beyond South Africa's borders, touching on the broader question of whether African economies can build the energy infrastructure needed to compete globally.
Private Sector and Renewable Energy Opportunities
Australia's experience showed that introducing more renewable generation does not automatically raise prices, contrary to a common assumption in South African policy circles. de Ruyter pointed to Australia's flourishing solar and wind sectors as evidence that private investment can drive down costs when market rules allow it. South Africa has begun rolling out rooftop solar incentives, but uptake among residential and commercial users has been uneven. Several large mining companies in the Northern Cape and Limpopo have already signed power purchase agreements with independent solar producers, bypassing Eskom entirely. These bilateral deals highlight the demand for cheaper electricity that the current system cannot meet.
What Comes Next
South Africa's government is currently reviewing electricity tariff structures ahead of the next regulatory period, with a decision expected before the end of the financial year. The energy regulator will face pressure from industrial lobby groups and consumer advocates with competing demands. de Ruyter urged South Africans to study the Australian example carefully, not as a perfect template but as proof that reform is possible when regulators and politicians work together. The question now is whether the next tariff decision moves toward the competition and efficiency gains he described, or whether political considerations once again defer the harder choices. Watch for the energy regulator's preliminary tariff proposal, expected within the next two months, to signal which direction the government intends to take.
