If your business planning still assumes rolling blackouts, it's worth updating that assumption. As of mid-2026, South Africa has gone more than a year without a single stage of load shedding, driven by sustained improvements in Eskom's generation fleet and its Energy Availability Factor. It's the longest stretch without cuts since 2018. That's genuinely good news, but it doesn't mean power risk has disappeared, and it doesn't mean resilience planning is now optional.
These are often confused, and it matters for how you plan:
Load shedding is a nationwide, Eskom-declared measure to protect the grid when supply can't meet demand, rolled out in stages and announced publicly in advance.
Load reduction is localised and ongoing in specific overloaded suburbs and feeders, typically cutting power in set morning and evening windows, and it can affect an area even while load shedding nationally stays suspended.
For a business, this means your specific location can still experience scheduled outages even during a "load shedding free" stretch, if you happen to sit on a feeder under load reduction.
Eskom's own winter outlook for 2026 has flagged that stages 2-6 remain possible if unplanned generation breakdowns exceed roughly 16,000MW during peak winter demand, a risk window that officially extended into August 2026. The grid is meaningfully more stable than it was in 2022–2023, but "stable" and "risk-free" aren't the same thing, and any return to shedding is something Eskom has said it would still need to announce.
Even with load shedding suspended, electricity tariffs have continued to climb - NERSA approved increases of close to 9% for Eskom's direct customers and municipal customers in 2026, with further increases already approved for 2027/28. For businesses running their own backup power (generators, diesel, on-site UPS at scale), rising tariffs combined with fuel and maintenance costs make self-managed resilience an increasingly expensive insurance policy - one you're paying for whether or not you ever need it.
Three years of severe disruption left a lasting impact on how South African businesses think about infrastructure — and that shift hasn't reversed just because the grid has stabilised. Planning for power resilience isn't about assuming the worst; it's about not needing to think about it at all, regardless of what the grid does next.
This is where colocating in a facility engineered for exactly this environment changes the equation. OADC's South African data centres are designed with redundant power infrastructure and backup systems built to maintain uninterrupted operations through extended outages - whether that's scheduled load shedding, localised load reduction, or an unplanned grid event. That's infrastructure resilience handled once, professionally, rather than managed in-house at every site you operate.
South Africa's power story in 2026 is a genuinely better one than it was three years ago. But the businesses that came through 2022-2023 without disruption were the ones that had already planned for volatility before they needed to. Whether the grid holds steady or conditions change again, colocating in an infrastructure-resilient facility means that's one less thing on your risk register.
