What is a Diesel Generator?

A diesel generator is the combination of a diesel engine with an electric generator (often an alternator). Basically, the engine starts burning diesel fuel and convert chemical energy into mechanical energy. Lastly, the alternator then starts to convert mechanical energy to electricity.

Why diesel?

• Diesel engines are more fuel-saving than petrol or natural gas engines.
• Diesel generators can run for the long time. This makes them an ideal for Bangladesh’s repeated electricity failure.
• Diesel generators are known for its longevity, energy, and dependability.

Q&A:

Q: Which diesel generators are widely used by the Bangladeshi people?

A: In Bangladesh, we use diesel generators mostly for industrial uninterruptible power supply, Hospital Operations, School, Factory, Bank and even large households. During power cut, they provide backup power supply and fulfil the shortage of electricity.

Diesel generators are built in different capacities (measured in kVA). The right size depends on your total electrical load and intended use.

Diesel Generators in Bangladesh

In Bangladesh, the demand for diesel generators is rising due to:

• Industrial expansion in garments, steel, cement, and IT.
• Growing reliance on 24/7 hospital and university backup systems.
• Government focus on mega projects & utilities.

That’s why companies look for trusted suppliers like Edison Power, who can provide complete solutions — from product selection to installation and AMC.

How to Choose the Right Generator Size (kVA)

One of the most common mistakes buyers make is choosing a generator that’s either too small or too large. The right generator must match your electrical load requirements.

Step 1: Evaluate Load

• Add the wattage of all devices you want to run.
• Then divide the total watts by 1000 to convert into kVA.
• Always add 20–25% buffer to handle surge loads.

Step 2: Consider Usage Type

• Prime power → Generator runs continuously (factories, plants).
• Standby power → Only used during outages (offices, hospitals).

Step 3: Industry Examples in Bangladesh

• Homes & Shops: 9–20 kVA (fans, lights, refrigerators, AC).
• Schools & Clinics: 30–60 kVA (computers, lights, medical equipment).
• Hospitals & Universities: 100–200 kVA (lab equipments, operating theatres).
• Garments & Factories: 350–500 kVA (machines, air compressors).
• Mega Projects & Power Plants: 1000–3000 kVA (entire facilities, export industries).

Q&A:

Q: What is the most popular generator size in Bangladesh?

A: For industries, the 100 kVA generator price in Bangladesh is one of the most searched queries. For mega projects, the 500 kVA diesel generator in Bangladesh and 1000 kVA diesel generator price in Bangladesh are most relevant.

Perkins vs Cummins Diesel Generators

Generator Price in Bangladesh – What Affects Cost?

When buyers search for diesel generator price in Bangladesh, they quickly realize there isn’t a single fixed price. Instead, cost depends on several factors:

Key Price Drivers:

1. Capacity (kVA): A 20 kVA home generator may cost a fraction of a 1000 kVA industrial generator.
2. Brand: Perkins (UK) and Cummins (USA) are premium , while local/chinese sets are cheaper, also less reliable.
3. Alternator: Stamford alternators add quality and price; alternatives like Mecc Alte may lower cost.
4. Canopy Type: Silent or containerized units are more expensive than open-frame sets.
5. Controller System: Advanced Deep Sea controllers with synchronization increase price.
6. After-Sales Service: AMC-inclusive packages offer better long-term value.

Q: What is the average price of a diesel generator in Bangladesh?

A: The average price of a 100 kVA generator may start in the mid-range, while a 500 kVA diesel generator in Bangladesh or a 1000 kVA generator is significantly higher. Instead of focusing on only upfront cost, buyers should focus on value, warranty and AMC support.

Maintenance & AMC – Why It Matters

A diesel generator is not just a one-time purchase. To ensure long life and reliable performance, it requires routine maintenance.

AMC (Annual Maintenance Contract) Benefits:

• Regular check-up and oil/filter changes.
• Preventive checks on fuel system, alternator, and controller.
• 24/7 emergency support across Bangladesh.
• Extends longevity and prevents costly breakdowns.

Q: Do I need AMC for my diesel generator in Bangladesh?

A: Yes. AMC ensures your generator runs efficiently, avoids sudden failures, and meets compliance standards — critical for factories, hospitals, and telecom operations.

Future of Diesel Generators in Bangladesh

While diesel remains the most reliable fuel for backup, the industry is evolving.

• Hybrid Solutions: Many factories combine solar + diesel backup.
• Containerized Gensets: Large 1000–3000 kVA sets now come in ISO containers for mobility and soundproofing.
• Emission Standards: Bangladesh may adopt stricter EU-style standards, making modern Perkins & Cummins sets more valuable.
• Digital Monitoring: Remote monitoring via Deep Sea 7420 & cloud-based systems is becoming standard for industrial clients.

This shows that investing in a premium diesel generator now (with Perkins or Cummins engines) is also future-proofing your power supply.
