Grid Connection — The Hidden Bottleneck (and Why Sonani's Doornpoort Link Matters)

Here's the problem nobody talks about enough. You can build the world's most efficient solar farm, but if you can't connect it to the grid, it's useless. South Africa's transmission network has been underfunded for years. The Generation Connection Capacity Assessment shows that supply areas like the Northern Cape, Western Cape, and Eastern Cape are already depleted — connection capacity reduced to zero.

However, there's good news for projects in Mpumalanga. The province still has approximately 3,320 megawatts of available connection capacity, along with KwaZulu-Natal at 5,500 megawatts, Gauteng at 4,680 megawatts, and Limpopo at 3,360 megawatts.

This is why Sonani's grid connection milestone is so significant. In late November 2025, they received their second Cost Estimate Letter from Eskom for connection to the Doornpoort Substation, approximately 8 kilometers from their site. Eskom's Grid Access Unit has confirmed available capacity. The total connection scope is valued at 75 million Rand. This isn't a speculative project — it's one that has secured the critical infrastructure link that many projects never obtain.
