As South Africa pushes forward with ambitious plans to transition to renewable energy, concerns are mounting over whether the country can meet its target of 19 gigawatts (GW) of renewable capacity by 2030. While policies like the Renewable Energy Independent Power Producers Procurement Programme (REIPPPP) aim to accelerate the shift, delays in project execution and grid infrastructure development are raising alarms about energy security and investor confidence.
Timeline Under “Immense Pressure”
Volker von Widdern, Head of Strategic Risk at Riskonet Africa, warned that South Africa risks a “second power crisis” within this decade due to slow progress in expanding transmission capacity. Despite having an installed generation capacity of around 40GW, effective output hovers near 30GW, leaving little room for demand spikes or unforeseen outages.
“The issue isn’t generation—it’s transmission,” von Widdern explained. While 400 billion rand has been allocated for grid upgrades, the current rollout of new transmission lines is far behind the 14,000-kilometer target set by the National Transmission Company of South Africa (NTCSA). At present, only a few hundred kilometers are being added annually, a pace von Widdern called “insufficient” to support the planned renewable energy expansion.
Risk of a Looming Power Shortfall
South Africa’s aging coal fleet is gradually being phased out, but renewable projects—particularly wind and solar—require robust grid infrastructure to deliver power to industrial hubs. Von Widdern cautioned that without rapid deployment of new transmission lines, the country could face severe electricity constraints between 2030 and 2035, even if renewable generation capacity increases.
“Right now, we’re delivering a couple of hundred kilometers of transmission lines per year when we need thousands,” he said. “If we don’t scale up within the next three to five years, we’ll hit a major power crunch.”
Calls for Faster Deployment and Private Sector Involvement
To accelerate progress, von Widdern proposed adopting more flexible models for grid expansion, including public-private partnerships and standardized approval processes for land use and environmental permits. He suggested treating transmission projects like toll roads, where private investors could finance and operate lines under long-term concessions.
“Capital isn’t the constraint—it’s the process,” he said. “We need parallel projects running simultaneously, with pre-approved templates for land agreements and construction to cut delays.”
Policy Uncertainty Deters Investment
Regulatory bottlenecks and policy inconsistency remain key hurdles. Lengthy environmental approvals and negotiations with landowners slow down critical projects, deterring private investment. Von Widdern urged policymakers to streamline processes, offering alternatives such as underground cabling or leasing land to expedite development.
The Path Forward
South Africa’s renewable energy ambitions hinge on overcoming these infrastructure and bureaucratic challenges. While the REIPPPP has successfully attracted private investment in generation, von Widdern stressed that without urgent upgrades to the grid, the country risks undermining its energy transition—and its economic stability.
“The window to act is closing fast,” he warned. “If we don’t move now, we’ll face another decade of energy insecurity.”
