How many ZESA units is ZiG 100
ZiG 100 buys 44.3 kWh of prepaid electricity in Zimbabwe — as your first purchase this month, including the 6% REA levy.
A hundred ZWG stays at the cheap end of the ladder, so almost all of it becomes units instead of being eaten by the higher bands. It is the classic small top-up for a home that cooks on gas and uses electricity for lights, a fridge and phones.
Band-by-band breakdown
ZESA charges in six steps each month. Here is exactly where ZiG 100 lands.
| Band | Units | ZWG/unit | Cost |
|---|---|---|---|
| First 50 units | 44.3 | 2.2585 | ZWG 100.00 |
| Total | 44.3 | — | ZWG 100.00 (≈ US$3.55) |
That is 11% of your 400 kWh discounted monthly quota. Anything above the quota in the same month is charged at the top band rate.
What ZiG 100 actually runs
44.3 kWh is about 3.3 days for a household that would otherwise burn through the whole 400 kWh quota in a month. Spent on one appliance at a time, it goes this far:
| Appliance | Typical draw | Runs for |
|---|---|---|
| Electric geyser (150 L) | 3,000 W | 14 h 46 min |
| Stove plate | 2,000 W | 22 h 8 min |
| Kettle (2 L) | 2,000 W | 22 h 8 min |
| Iron | 1,200 W | 36 h 54 min |
| Microwave | 1,000 W | 44 h 17 min |
| Borehole pump (1 hp) | 750 W | 2.5 days |
| TV + decoder | 120 W | 15 days |
| Five LED bulbs | 50 W | 37 days |
| Wi-Fi router | 10 W | 184 days |
| Fridge / freezer | 1.2 kWh/day | 37 days |

Questions
- Is ZiG 100 of ZESA always 44.3 units?
- No. ZESA uses a stepped tariff, so the answer depends on how much you have already bought this calendar month. 44.3 kWh assumes this is your first purchase of the month, starting from the cheapest band. Later purchases in the same month buy fewer units for the same money.
- How long does ZiG 100 of ZESA last?
- ZiG 100 buys 44.3 kWh, which is about 3.3 days for a household that would otherwise use its full 400 kWh monthly quota (≈ 13.3 kWh a day). Use less than that and it lasts proportionally longer.
- Do these prices include the REA levy?
- Yes. Every figure on this page includes the 6% Rural Electrification levy, exactly as ZETDC charges it. Rates are the ZERA-approved schedule effective 2026-09-21.
