At Total Power in Dubai, we know how important it is to have power all the time — especially during emergencies. That’s why many homes, shops, and companies use backup generators. But one common question we hear is:
How much does it cost to run a backup generator per hour or month?
Let’s break it down in simple and easy English.
🛠️ What is a Backup Generator?
A backup generator is a machine that gives electricity when the main power goes out. It runs on fuel like diesel, gasoline (petrol), or propane. People in Dubai use it for homes, buildings, events, and work sites.
If you don’t want to buy one, you can use generator rental Dubai services — it’s easy and more affordable for short-term use.
💰 Cost Per Hour
The price depends on:
-
Fuel type (diesel, petrol, etc.)
-
Generator size (like 5 kVA, 10 kVA, etc.)
-
Fuel price in Dubai
-
How many hours you use it
Here’s a simple table to help you:
| Generator Size | Fuel Type | Fuel Use (Liters/hour) | Cost Per Hour (Approx) |
|---|---|---|---|
| 5 kVA | Petrol | 1 to 1.5 | AED 4.50 – AED 7.00 |
| 10 kVA | Diesel | 2 to 3 | AED 7.00 – AED 11.00 |
| 20 kVA | Diesel | 3 to 4.5 | AED 11.00 – AED 17.00 |
| 50 kVA | Diesel | 6 to 9 | AED 18.00 – AED 28.00 |
| 100 kVA | Diesel | 10 to 15 | AED 30.00 – AED 45.00 |
💡 Prices may change depending on Dubai fuel rates.
📅 Cost Per Month
Let’s say your 10 kVA generator runs 5 hours daily.
-
Uses 2.5 liters per hour
-
Daily use: 2.5 x 5 = 12.5 liters
-
Monthly: 12.5 x 30 = 375 liters
-
If diesel costs AED 3 per liter: 375 x 3 = AED 1,125 per month
So, it could cost around AED 1,125 per month to run your generator.
💡 What Can Change the Cost?
Here are some things that affect the cost of using a generator:
-
Fuel Type – Diesel is usually cheaper and lasts longer.
-
Generator Size – Bigger machines use more fuel.
-
How Long You Run It – More hours = more cost.
-
Maintenance – Oil, filters, and repairs cost money too.
-
New or Old – Newer generators save more fuel.
If you use generator rental Dubai services, you may also pay a small rental fee. But you don’t have to worry about buying or servicing the machine yourself.
✅ How to Save Fuel and Money
Here are some smart tips from Total Power:
-
Only run the generator when needed.
-
Turn off extra lights and machines.
-
Use energy-saving items like LED bulbs.
-
Keep the generator serviced and clean.
-
Choose the right size — not too big or too small.
-
Try generator rental Dubai instead of buying one for short-term use.
🧾 Final Thoughts
Backup generators help keep your life running during power cuts. But they do cost money to use. The cost depends on size, fuel, and time. Small generators may cost just a few dirhams per hour. Bigger ones cost more.
