DEWA uses a progressive slab system — the more you consume, the higher the rate. Staying in lower slabs can save you hundreds of dirhams every month.
| Monthly Consumption (kWh) | Rate (fils/kWh) | Approx. Cost with Fees (AED/kWh) |
|---|---|---|
| 0 – 2,000 | 23 | 0.38 |
| 2,001 – 4,000 | 28 | 0.42 |
| 4,001 – 6,000 | 32 | 0.46 |
| 6,001+ | 38 | 0.52 |
Pro Tip: Cooling accounts for 60-70% of bills. Reducing usage helps you stay in lower slabs.
