Dubai and Abu Dhabi charge for household electricity on two completely different mechanisms. DEWA prices Dubai on the monthly total, in four slabs from 23 fils to 38 fils per kWh. ADDC prices Abu Dhabi on a daily average against an allowance set by property type, at 26.8 fils inside the allowance and 30.5 fils above it for expatriate customers.
Which is why the August bill argument at every UAE dinner table never resolves. Your friend in an Abu Dhabi villa pays less than you do in a Dubai villa on identical consumption. Your colleague in an Abu Dhabi flat pays more than you do in a Dubai flat on identical consumption. Both of them think they know which emirate is cheaper. Neither of them is wrong, and neither of them has read the tariff.
We pulled both tariff tables from the utilities themselves on 10 August 2026 and ran the same three consumption levels through each. Everything below is arithmetic on published rates, shown in full so you can check it against your own bill.
How does Dubai charge for electricity?
Dubai charges electricity through DEWA's slab tariff, applied to the total kilowatt-hours a property consumes in a calendar month. The first 2,000 kWh cost 23 fils each. Consumption above that is charged in three rising bands, reaching 38 fils per kWh beyond 6,000 kWh. DEWA labels the four bands Green, Yellow, Orange and Red, and states that the structure follows a decision of the Dubai Supreme Council of Energy.
The table below is DEWA's published residential slab tariff, read from dewa.gov.ae on 10 August 2026.
Two charges sit on top of the slab and neither appears in the headline rate. DEWA's fuel surcharge for August 2026 is 6.0 fils per kWh of electricity, applied to every unit consumed and revised as fuel prices move. A meter service charge of AED 5, AED 6 or AED 35 per month applies depending on meter type. VAT at 5% is then applied to these tariffs.
How does Abu Dhabi charge for electricity?
Abu Dhabi charges electricity through ADDC's Green and Red band system, applied to daily average consumption rather than a monthly total. An expatriate customer pays 26.8 fils per kWh inside the Green allowance and 30.5 fils per kWh above it. A UAE National pays 6.7 fils and 7.5 fils on the same structure. ADDC states that its charges are inclusive of VAT at 5%, and Abu Dhabi levies no fuel surcharge.
The allowance itself is the part almost nobody quotes, and it is where the whole system turns. It is set per day, and it changes with the type of property you live in.
An expatriate villa in Abu Dhabi receives ten times the daily electricity allowance of an expatriate apartment. Both pay the same rate per unit. The property type does not change the price of electricity in Abu Dhabi — it changes how much of it you may use before the price goes up.
Which emirate's summer electricity bill is actually higher?
Neither emirate is uniformly cheaper — the answer flips with the property. At 6,000 kWh in a 31-day August, a Dubai household pays roughly AED 2,121 in electricity charges while an Abu Dhabi expatriate villa on identical consumption pays roughly AED 1,608, a gap of about AED 513. At the same 6,000 kWh, an Abu Dhabi expatriate apartment pays roughly AED 1,807, which is less than Dubai but AED 199 more than the Abu Dhabi villa next door.
The table below runs three consumption levels through both published tariffs over a 31-day month, so the mechanism is visible rather than asserted.
Why does an Abu Dhabi apartment hit the expensive rate so much sooner?
An Abu Dhabi expatriate apartment leaves its cheap rate at 20 kWh per day, which is about 620 kWh across a 31-day month. A Dubai home stays in its cheapest slab all the way to 2,000 kWh in the month. The Abu Dhabi apartment allowance is therefore roughly three times tighter than Dubai's first slab, and an air-conditioned flat in August passes it without doing anything unusual.
At the other end, the picture inverts completely. An Abu Dhabi expatriate villa carries a 200 kWh per day allowance, about 6,200 kWh in a 31-day month — a threshold that sits just above the 6,001 kWh point where Dubai's most expensive 38-fils band begins. An Abu Dhabi villa can consume all summer and still pay its lowest rate on every unit, while a Dubai villa at the same consumption has already climbed through three bands.
The counter-intuitive part is worth stating plainly, because the headline rates say the opposite: Abu Dhabi's cheapest expatriate rate of 26.8 fils is higher per unit than Dubai's cheapest slab of 23 fils. Abu Dhabi villas still pay less in August. The structure, not the rate, is doing the work.
What is the fuel surcharge, and why is it not on an Abu Dhabi bill?
The fuel surcharge is a per-unit charge DEWA applies on top of the slab tariff, set at 6.0 fils per kWh of electricity for August 2026 and revised as the price of fuel supplied to DEWA's generation plants moves. ADDC's published residential tariffs carry no equivalent line, which is why an Abu Dhabi and a Dubai bill for the same consumption cannot be compared on the headline rate alone.
The surcharge is also the part of a Dubai bill that can change without your consumption changing at all. A household that used exactly the same electricity in two consecutive months can receive two different bills, and the slab tariff will not explain the difference. Check the surcharge line before assuming the extra came from the air conditioning.
How do you work out which band you are in?
Working out your band takes one number off your bill and one division. Dubai residents need the monthly kWh total and nothing else. Abu Dhabi residents need the monthly kWh total divided by the number of days in the billing period, because the Green allowance is a daily average and a single heavy week can pull it over.
- Find the electricity consumption in kWh for the billing period — not the dirham amount.
- In Dubai: compare that total against 2,000, 4,000 and 6,000 kWh to see which slabs you crossed.
- In Abu Dhabi: divide the total by the number of days billed, then compare against 20 kWh/day for an apartment or 200 kWh/day for a villa.
- Repeat with January's bill. The gap between January and August is your cooling load, and it is the only part of the bill you control.
What actually moves the number you control?
Neither tariff is negotiable, so the only variable a UAE household controls is kilowatt-hours, and in August most of them go through the air conditioning. DEWA states the position directly on its own conservation guidance: "Air conditioning is one of the largest contributors to household electricity consumption, particularly during the summer months."
DEWA's published cooling advice is short, specific and free. Set the thermostat to 24°C in summer and use auto mode so the system cycles efficiently. Clean the air conditioner filters at regular intervals. Caulk and weatherstrip doors and windows so cool air stops escaping. Keep windows and doors fully closed while the AC runs, and use individual room controls where the system has them so you are not cooling empty rooms.
A system that is short of refrigerant, running on a clogged filter or cycling against a failed thermostat runs longer to reach the same temperature, and running longer is the whole mechanism by which a bill grows. Fixing it is a service call, not a tariff negotiation — and in Dubai a routine AC service runs AED 150–400 per unit, roughly what one extra band costs a villa in a single August month.

Frequently asked questions about Dubai and Abu Dhabi electricity tariffs
Is electricity cheaper in Abu Dhabi or Dubai?
Electricity in Abu Dhabi is cheaper than Dubai for a villa and closer to level for an apartment. At 6,000 kWh in a 31-day August, a Dubai household pays about AED 2,121, an Abu Dhabi expatriate apartment about AED 1,807 and an Abu Dhabi expatriate villa about AED 1,608. Abu Dhabi's cheapest expatriate rate of 26.8 fils is nonetheless higher per unit than Dubai's 23 fils first slab.
What are DEWA's electricity slab rates?
DEWA charges Dubai residential electricity at 23.0 fils per kWh for the first 2,000 kWh in a month, 28.0 fils from 2,001 to 4,000 kWh, 32.0 fils from 4,001 to 6,000 kWh, and 38.0 fils above 6,000 kWh. A fuel surcharge of 6.0 fils per kWh applies for August 2026, along with a meter service charge of AED 5 to AED 35 and 5% VAT.
What is the Green band allowance in Abu Dhabi?
Abu Dhabi's Green band allowance for an expatriate customer is 20 kWh per day in an apartment and 200 kWh per day in a villa. UAE Nationals receive 30 kWh per day in an apartment and 400 kWh per day in a villa. Consumption inside the allowance is charged at the lower Green rate; only the excess is charged at the higher Red rate.
Why is my Dubai bill higher when my usage did not change?
A Dubai electricity bill can rise without any change in usage because DEWA's fuel surcharge is revised as fuel prices move, and it applies to every kilowatt-hour consumed. The surcharge stands at 6.0 fils per kWh for August 2026. Crossing a slab boundary also reprices consumption, so 2,001 kWh costs more per unit at the margin than 2,000 kWh.
Does Abu Dhabi have a fuel surcharge like Dubai?
Abu Dhabi's published residential tariffs carry no fuel surcharge line, unlike Dubai, where DEWA applies a separate per-kilowatt-hour surcharge revised with fuel prices. ADDC states that its residential charges are inclusive of VAT at 5%. Comparing a Dubai and an Abu Dhabi bill on the headline rate alone therefore understates the Dubai figure.
Does servicing my AC reduce my UAE electricity bill?
No UAE utility publishes a percentage saving for servicing an air conditioner, so any guaranteed figure you are quoted is unmeasured. DEWA does state that air conditioning is one of the largest contributors to household electricity consumption in summer, and recommends clean filters, a 24°C thermostat setting and auto mode. A system running longer to reach the same temperature consumes more.
