Eskom urged to shift grid control to NTCSA amid South Africa power strain

South Africa’s power sector is under fresh strain as tensions rise between Eskom and independent power producers, sharpening concerns about grid access, energy security and the pace of renewable energy investment. 

A recent court ruling has brought the issue into sharper focus, raising questions about how scarce grid capacity is shared in one of Africa’s tightest electricity markets.

Demand for solar, wind and battery storage projects is growing, but limited transmission capacity is slowing new connections. 

For investors, the dispute cuts deeper than a single case.

It speaks to whether South Africa’s reform plans can deliver a system that is open, predictable and fair for private capital. 

The stakes are high. Power cuts still weigh on businesses and households, and reliable electricity remains central to economic growth.

Court ruling puts grid access in focus 

Independent producers, through the South African Independent Power Producers Association, say Eskom’s control of grid connections is limiting competition.

Their concerns follow a high court decision that set aside Eskom’s move to shift a grid allocation from Mulilo Energy Holdings to Scatec, and ordered the utility to pay legal costs. 

At the center is a growing bottleneck. Grid space is scarce, especially in the Northern, Eastern and Western Cape, where renewable resources are strongest.

That has intensified competition and placed more attention on how allocations are made.

Conflict concerns and reform push 

Eskom had sought to redirect capacity from Mulilo’s 240-megawatt solar project in the Free State to a rival project under the Renewable Energy Independent Power Producer Procurement Programme.

The utility says it will not appeal the ruling and will follow a fair and transparent process. 

Still, the case has revived concerns about Eskom’s dual role as both generator and gatekeeper of grid access.

Industry participants say that overlap risks conflicts of interest and weakens trust in the system.

Calls to shift control to NTCSA 

Producers are now urging a faster shift of grid allocation powers to the National Transmission Company South Africa, which was created to run the transmission network independently.

They argue this would help ensure neutrality and speed up stalled projects. 

The government has backed plans to separate Eskom’s units, but progress has been uneven.

For now, grid allocation still sits with Eskom’s distribution arm, a point of friction for developers. 

Developers also point to changing rules, complex approvals and high upfront costs as barriers to investment.

In some cases, requirements from Eskom and regulators depend on each other, slowing projects before they begin. 

As South Africa works to add renewable capacity and steady its power supply, the outcome of this dispute will be closely watched by investors and policymakers alike.
