See, even though there are very less power cuts in India right now compared to a few decades ago, still, power backup is somewhat of a necessity in the country. We can’t just deny that. And if you agree to that, then you must already know how long it has been since people of India began to use generators that run on petroleum fuel to power up their spaces/homes. Right? Well, these days, a lot of people are up for the use of inverters and generators, especially in villages people prefer to go with the generator option because it is super convenient, and you can run a generator whenever there is a power cut. So, just in case, if you were wondering about which are the companies to trust when buying a generator in India, then just keep on reading this list of the Top 10 Leading Generator Companies in India 2025. That’s all!
1. Caterpillar India Pvt. Ltd.
Whenever we’re talking about some piece of machinery, be it those heavy generators, well, no doubt, we can’t just skip past Caterpillar’s name like it is nothing. Nah, it actually deserves the first spot on today’s list, and you’ll come to know why that is the case. Just so you know, if you go by their offerings, Caterpillar’s gensets are powered from 7.5 kVA to an incredible 7520 kVA. They are the perfect source of power for data centers, construction, and industrial zones. The C13, C15, and the 3516E are the heavy-duty type of models that have been tough tested and proven over and over again, pretty much.
2. Cummins India Limited
And then, well, at number two, there is Cummins, you know, one of the very few brands whose name always comes up when there is a conversation going on about diesel generators, particularly. Their generators of the power ranging from 7.5 kVA to 3750 kVA are popular for being fuel-efficient, emission-compliant, and load fluctuation responsive. And to be more specific here, well, models like KTA50 and QSK95 are among the most reliable in the healthcare, telecom, and industrial sectors.
3. Kirloskar Oil Engines Limited (KOEL)
Kirloskar? Yes, that’s one of the most famous generator brands in the country right now, and did you know that KOEL Green Gensets are one of the top-selling generator units in the whole country? It is the main reason why Kirloskar is at #3 on our ranking, no doubt. As of 2025, though, right here in India, small businesses and big establishments are using these gensets, which range from 3 kVA to 1010 kVA.
4. Mahindra Powerol
Up next, well, Mahindra is probably known to you for its vehicles, but ranking at #4, Mahindra Powerol is getting attention with its small and quiet gensets that are causing a quiet revolution (noise, or rather, less noise). Talking about specific models, see Powerol, initially the first choice for banks, telecom, and shops with a capacity of 5 kVA to 625 kVA, has become a top choice for homes as well. And other than the performance part, see also, with more than 400 service centers all over India, servicing is very convenient.
5. Ashok Leyland (LEYPOWER)
We get it, some of you may be like: Ashok Leyland makes generators too? Well, of course, they do; it is not just about those big trucks they make, they carry on the same quality and name in the generator segment of the Indian market too, but with the LEYPOWER division or sub-brand. These gensets with a power range from 5 kVA to 2500 kVA are designed for infrastructures, hospitals, and commercial spaces. The company has intended them to be fuel-efficient, low-noise, and robust against Indian conditions.
6. Honda India Power Products Ltd.
Do you agree with the fact that it is not necessary for every person to have a power source on an industrial scale? Well, true to this, this is the area where Honda’s brilliance is demonstrated, you know, by their portable, low-capacity generators, which are just right for homes, workshops, and small business places; they hold the #6 position. Right now, as of 2025 well, through inverter technology and electronic fuel injection, Honda provides a consistent output with models such as the EU70is and EU30i.
7. Greaves Cotton Limited
Oh, and in position #7, Greaves is the name we are talking about, one of the long-time players in India’s engineering scene, and now, it is venturing out with next-gen, IoT-enabled gensets right here in the country.

8. Mitsubishi Heavy Industries

Right here in India, Perkins, with its generator engines from 0.5L to above 4000 kVA, is a widely used source of power in heavy industries and as a backup power. Performance at high altitudes and in high temperatures is what makes the 1100, 1200, and 4000 series stand out most of all.
10. Atlas Copco India
Coming to the last spot and finishing this list off, there is Atlas Copco, basically a brand super popular in India, mainly for their mobile or portable generators. With products extending to 100 kVA, they are mainly concentrating on the sectors of construction, events, and rentals. Recently, though, they have gone into hybrid and energy storage systems as well, which is a great help in cutting down emissions and fuel consumption.
Conclusion
Sure, generator is a niche market in India and people nowadays prefer to buy an inverter rather than a generator, but still, if you’re looking forward to buy one, do prefer any of these companies and you’ll be good for the most part. That’s all!
