A genset, commonly known as a diesel generator (DG), is a power generation system that converts diesel fuel into electrical energy. It consists of an engine, alternator, control panel, cooling system, exhaust, and enclosure—working together to deliver reliable electricity when grid power is unavailable or insufficient.

“Whether you need to buy a genset for your business, factory, hospital, or construction site, understanding DG set types, cost, and hybrid options is critical in 2026.”

Gensets can operate as:
•Backup power during outages
•Prime power in remote or off-grid locations
•Peak load support alongside grid or solar power

Why Gensets (DG Sets) Are Still Critical for Businesses in 2026
Despite the growth of renewable energy, gensets continue to play a vital role across industries.

Key reasons businesses rely on gensets:
•Instant backup during grid failures
•Stable power for sensitive equipment
•Support during peak demand and load shedding
•Reliable power in remote and construction sites
•Essential compliance for hospitals, IT parks, and process industries

Even the most advanced solar or battery systems rely on gensets as a final layer of reliability

Did you know?
•A genset can start and supply power within seconds of a grid failure
•Gensets are often mandatory for fire safety systems, elevators, and critical loads
•Hybrid systems combining DG + solar + battery can reduce diesel consumption by 30–70%
•Proper sizing improves fuel efficiency and engine life significantly

What Components Are Included in a Genset (DG Set) System?
A genset installation involves more than just the generator.
Core components:
•Diesel engine – Produces mechanical power
•Alternator – Converts mechanical power into electricity
•Control panel – Manages operation, protection, and automation
•Fuel system – Tank, filters, and fuel lines
•Cooling system – Radiator or heat exchanger
•Exhaust system – Silencer and piping
•Acoustic enclosure / canopy – Noise and weather protection
•Power & control panels – AMF, synchronization, load sharing

Types of Gensets (DG Sets) Based on Application
Choosing the right genset depends on how it will be used.
1. Standby gensets
•Used only during power outages
•Common in offices, malls, apartments, hospitals
2. Prime power gensets
•Runs for long hours
•Ideal for remote sites, mining, oil & gas, telecom
3. Continuous power gensets
•Operates 24/7 at constant load
•Used in industrial and utility-scale applications

Typical hybrid configuration:
Solar + Grid + DG + BESS (Battery Energy Storage System)

Role of the genset in a hybrid system:
•Covers solar intermittency (clouds, night-time)
•Handles peak load demand beyond solar capacity
•Provides black-start capability
•Acts as backup when batteries are depleted
•Stabilizes voltage and frequency

In many installations, the genset runs only when needed—significantly reducing diesel usage and operating costs

How to Choose the Right Genset (DG Set) for Your Business
Selecting the wrong genset leads to inefficiency, higher fuel consumption, and frequent breakdowns.

Key factors to consider:
1.Connected load & running load (kW / kVA)
2.Starting current of motors and compressors
3.Operating hours per day
4.Fuel efficiency at partial load
5.Emission norms (CPCB II / IV+)
6.Noise restrictions (silent or super silent models)
7.Future load expansion
8.Service and spare availability

Genset sizing: why it matters
Oversized gensets waste fuel and suffer from wet stacking. Undersized gensets trip frequently and damage equipment.
A properly sized genset:
•Operates at 60–80% load
•Delivers optimal fuel efficiency
•Reduces maintenance cost
•Extends engine life

Genset Price in India : Cost by kVA Rating
Genset pricing depends on rating, brand, enclosure, and compliance.
•15–30 kVA: ₹2.5–5 lakh
•50–125 kVA: ₹6–15 lakh
•160–500 kVA: ₹18–60 lakh

•Above 500 kVA: Project-based pricing
Additional costs may include:
•AMF/synchronization panels
•Fuel tanks
•Cabling & installation
•Exhaust piping & civil work

Genset vs Battery Storage: Why DG Sets Still Matter
In modern installations, gensets are rarely used alone and are increasingly combined with solar power systems and battery energy storage systems to reduce diesel consumption and operating costs.While batteries are excellent for short-duration backup, gensets remain unmatched for:
•Long outages
•High surge loads
•Continuous power requirements
•Emergency and safety systems
The future isn’t genset vs battery—it’s genset + battery + solar.

How to get the right genset solution

The best genset decision starts with understanding your load profile, operational needs, and future energy strategy.
Instead of selecting based on price alone:
•Compare multiple technical solutions
•Evaluate fuel consumption curves
•Check service network and response time
•Plan for hybrid integration from day one

Planning to Buy a Genset?
The right DG set depends on load profile, operating hours, fuel efficiency, emission norms, and service support. Comparing genset prices alone can lead to higher lifetime costs. Always evaluate technical suitability, after-sales support, and future hybrid compatibility before finalizing a supplier.

Need the Right Genset for Your Project?
Whether you need a standby DG set, prime power solution, or a hybrid system integrating solar and battery storage, choosing the right genset is critical for reliability and cost control. A properly engineered genset solution ensures uninterrupted power, lower diesel consumption, and long-term operational efficiency.
