Load Shedding Stages 1–8 Explained South Africa
South Africa's load shedding stages are often misunderstood. Many people think Stage 6 means 6 hours of darkness — it actually means up to 12. Others don't realise that the same area can be hit multiple times per day at higher stages. This guide explains exactly what each stage means, how the block scheduling system works, and how to check your specific area's schedule.
The Complete Stage Reference Table
| Stage | MW to Shed | Hours Off per Day (approx) | Typical Frequency | Daily Life Impact |
|---|---|---|---|---|
| Stage 1 | 1,000 MW | ~2 hours | Once every 2 days | Minor — 1 slot per cycle |
| Stage 2 | 2,000 MW | ~4 hours | Once per day | Noticeable — affects morning or evening |
| Stage 3 | 3,000 MW | ~6 hours | Once to twice per day | Significant — impacts work and cooking |
| Stage 4 | 4,000 MW | ~8 hours | Twice per day | Severe — 12-hour rolling cycles |
| Stage 5 | 5,000 MW | ~10 hours | Multiple times per day | Critical — inverter essential |
| Stage 6 | 6,000 MW | ~12 hours | Multiple times per day | Extreme — 12 hours off daily |
| Stage 7 | 7,000 MW | ~14 hours | Multiple times per day | Not yet implemented in SA |
| Stage 8 | 8,000 MW | ~16 hours | Multiple times per day | Not yet implemented in SA |
Note: "Hours off per day" is an approximation — actual times depend on your area's block schedule. Some areas may experience slightly more or fewer hours depending on Eskom's grid configuration.
How the Block Scheduling System Works
Eskom divides South Africa into numbered areas (typically 1–16 within each municipality's schedule) and rotates outages through these areas. Each block is assigned a time slot that shifts with each stage level:
- Stage 1–2: 2-hour blocks — each area gets one 2-hour slot per day or every 2 days
- Stage 3–4: 2.5-hour blocks — areas cycle more frequently
- Stage 5–6: Areas cycle on a 4-hour block, twice daily — meaning 8–12 hours off in a 24-hour period
The schedules operate on a 4-day cycle that then repeats. Your block number determines when you're off within each day of that cycle. This is why your load shedding times aren't the same every day — they shift through the rotation.
How to Check Your Area's Schedule
- EskomSePush app (best option): Free on Android and iOS. Enter your suburb or nearest Eskom substation and it will show your exact schedule with push notifications before each outage. By far the most popular and accurate SA load shedding tracker.
- loadshedding.eskom.co.za: Official Eskom schedule lookup by suburb
- Your municipality's website: Most municipalities publish their own block schedules, which may differ from Eskom's national schedule
- Power Alert: Alternative app with similar functionality to EskomSePush
A Brief History of Stage 6+ Load Shedding in SA
South Africa first experienced Stage 4 in 2019. Stage 6 was first implemented in December 2019 during a period of severe generation failures. The frequency and severity of load shedding has increased substantially since then:
- 2019: First Stage 4 and Stage 6 implemented
- 2020: COVID lockdowns briefly reduced demand; Stage 6 returned in December
- 2022: Record load shedding hours — over 3,000 hours of combined outages across SA
- 2023: South Africa spent more days in Stage 5–6 than any other level. Stage 6 became normalised for millions of households.
- 2024–2025: Improvements in Eskom's maintenance programme reduced frequency. Stage 1–3 became more common with occasional Stage 4–6 spikes.
Business Impact of Each Stage
Load shedding is estimated to cost the South African economy R500 million to R4 billion per day depending on severity. For small businesses:
- Stage 1–2: Manageable with a UPS and good schedule awareness
- Stage 3–4: Serious operational disruption — generator or inverter essential
- Stage 5–6: Many businesses cannot function without backup power. Retail, restaurants, manufacturing all severely impacted.
Preparation Guide by Stage Level
| Stage | Minimum Preparation | Recommended Investment |
|---|---|---|
| 1–2 | Power bank, rechargeable lights, gas stove | UPS for router (R800–R2,000) |
| 3–4 | Above + UPS + generator or inverter | Home inverter + 100Ah lithium (R15,000–R25,000) |
| 5–6 | Full inverter + battery system essential | Hybrid solar + lithium battery bank (R60,000+) |

Frequently Asked Questions
Why does my area sometimes go off at different times than the schedule says?
Several reasons: Eskom may have moved between stages during the day (EskomSePush usually updates within minutes), your municipality may implement supplementary outages, or there may be a local fault in addition to scheduled load shedding. A fault-related outage will typically be unscheduled and last longer than a load shedding slot.
Can load shedding be Stage 6 in one part of SA and Stage 2 in another?
No — the stage is national. Eskom declares a stage nationally and all areas rotate accordingly. However, individual areas within a stage may have different outage times depending on their block number. Some areas may be on a Notified Maximum Demand (NMD) agreement that exempts them from certain stages.
Will Stage 7 or Stage 8 ever happen in South Africa?
Eskom has published contingency plans for Stage 7 and Stage 8, but has never implemented them. Stages 7–8 would represent near-total grid collapse scenarios. The risk is real but considered low given that demand management (large industrial customers) provides a buffer before those extremes are reached.
