How much is 100 units of ZESA
100 units (kWh) of prepaid electricity costs ZWG 239.97 — about US$8.51 — as your first purchase this month, including the 6% REA levy.
A hundred units clears the two cheapest bands and stops right before the step up. For a home that cooks on gas and uses electricity for lights, a fridge, a TV and phone charging, this is the shape of a normal top-up rather than an emergency one.
Band-by-band breakdown
ZESA charges in six steps each month. Here is exactly what 100 units costs.
| Band | Units | ZWG/unit | Cost |

| First 50 units | 50.0 | 2.2585 | ZWG 112.93 |
| 51 – 100 units | 50.0 | 2.5408 | ZWG 127.04 |
| Total | 100.0 | — | ZWG 239.97 (≈ US$8.51) |
That is 25% of your 400 kWh discounted monthly quota. Anything above the quota in the same month is charged at the top band rate.

Questions
- Is 100 units of ZESA always ZWG 239.97?
- No. ZESA uses a stepped tariff, so the price depends on how much you have already bought this calendar month. ZWG 239.97 assumes this is your first purchase of the month, starting from the cheapest band. Later purchases in the same month cost more per unit.
- Can I pay for ZESA in US dollars?
- ZETDC bills in ZWG. The ≈ US$8.51 figure uses the published reference rate of about 28.2 ZWG per US$; USD payment channels convert at the rate they offer on the day.
- How long does 100 units of ZESA last?
- About 7.5 days for a household that would otherwise use its full 400 kWh quota in a month (≈ 13.3 kWh a day). Run less than that and it stretches further: 100 units is 33 h 20 min of a 3 kW geyser, or 83 days of a fridge on its own.
- 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.
