Diesel genset price in India: what you pay per kVA, 10 to 320 kVA

A new CPCB IV+ silent diesel genset costs roughly ₹3.5 lakh to ₹6 lakh in the 10 to 40 kVA range, around ₹11 lakh at 125 kVA and over ₹20 lakh at 250 kVA, going by prices dealers list online. The bigger the set, the less you pay for each kVA: about ₹36,500 per kVA for a 10 kVA set, against about ₹8,600 per kVA at 250 to 320 kVA. Here is what dealers list, what the per-kVA numbers mean and what pushes a quote up.

Do makers publish genset prices?

Not that we could find. We found no current price list from Kirloskar Oil Engines, Mahindra Powerol, Cummins India or Greaves; their pages give ranges and specifications. The price you pay is set by the dealer and depends on the enclosure, the control panel, delivery and taxes.

So the figures below are dealers' asking prices, read from their listing pages on 27 October 2026. They are a guide to the range, not a quote. Ask at least two authorised dealers for a written quote on the same specification.

Genset prices by kVA: what dealers list

All of these are silent (canopy) diesel sets listed as CPCB IV+, the emission norm every new set up to 800 kW must meet (see our CPCB IV+ explainer).

Size	Brand as listed	Dealer, city	Listed price	Price per kVA
10 kVA (air-cooled)	Kirloskar	Swastik Power, Chandigarh	₹3,65,000	₹36,500
15 kVA	Kirloskar	Swastik Power, Chandigarh	₹3,85,000	₹25,700
25 kVA	Kirloskar	Swastik Power, Chandigarh	₹5,50,000	₹22,000
30 kVA	Kirloskar	Grace Gensets, Gurugram	₹5,36,000 + GST	₹17,900
30 kVA	Kirloskar	Swastik Power, Chandigarh	₹5,70,000	₹19,000
40 kVA	Kirloskar	Grace Gensets, Gurugram	₹5,85,000 + GST	₹14,600
58.5 kVA	Kirloskar	Swastik Power, Chandigarh	₹7,50,000	₹12,800
125 kVA	Tata engine	Rishabh Power Solutions, Ghaziabad	₹11,20,909 (approx.)	₹9,000
250 kVA	Kirloskar	Northern Consultancies, Rohtak	₹21,50,000	₹8,600
320 kVA	Mahindra	Grace Gensets, Gurugram	₹27,50,000 + GST	₹8,600

Price per kVA is the listed price divided by the kVA rating, rounded. Grace Gensets says 18% GST is extra on its prices; the other pages do not say whether GST is included, so ask.

Alpha Diesels, a Bhiwadi dealer that says it is an authorised Greaves Power dealer for North India, publishes wider bands from quotes it has seen in 2024 to 2026:

Size	Indicative price band
5 to 25 kVA	₹1.5 to 4 lakh
30 to 62.5 kVA	₹4 to 8 lakh
82.5 to 125 kVA	₹8 to 14 lakh
160 to 250 kVA	₹14 to 25 lakh
320 to 500 kVA	₹25 to 50 lakh
625 to 1,000 kVA	₹50 to 90 lakh

Most of the listed prices above sit inside these bands. The 10 and 15 kVA listings are near the top of the first band, and the 25 kVA listing is above it.

Why does a small genset cost more per kVA?

A 10 kVA set and a 40 kVA set both need an engine, an alternator, a control panel, a fuel tank, a battery and an acoustic canopy. Many of those parts do not get four times dearer when the set gets four times bigger. The fixed part of the cost is spread over fewer kVA in a small set.

That is why the price per kVA falls fast up to about 60 kVA, and then flattens out between 125 and 320 kVA at around ₹8,600 to ₹9,000.

It is also why you should not buy a bigger set just because the kVA looks cheap. A set that runs well below its rating burns more diesel for each unit of power and can suffer wet stacking, as our fuel consumption guide shows. Size it on your load first, using our genset sizing guide, then compare prices.

What drives the price of a genset?

Alpha Diesels lists the things that move a final quote:

• Brand. Its page says the upper end of each band is for premium brands with fuller specifications.
• Canopy. An open set is cheaper than a silent one. Every listing in our table is silent.
• AMF panel. An automatic mains failure panel starts the set when the grid fails and switches the load over. It is an option, not standard on every quote.
• Fuel tank size.
• The maker's current rates, which change through the year.
• Delivery to site and taxes.

Two more things to check on any quote:

• The emission norm. Since 1 July 2024 a new set up to 800 kW must be CPCB IV+. Alpha Diesels' page says CPCB IV+ sets cost 10 to 15% more upfront than the CPCB II sets they replaced. Makers do not publish a figure for this.
• The rating. One listing we read gave a different kVA in its title and its specification. Check that the price is for the prime rating you need, on the maker's spec sheet.

Worked example: comparing two 30 kVA quotes

Say a workshop has two quotes for a 30 kVA silent CPCB IV+ set, matching the two listings in the table:

• Quote A: ₹5,36,000 plus 18% GST
• Quote B: ₹5,70,000, GST not stated

Quote A with GST is ₹5,36,000 × 1.18 = ₹6,32,480.

If Quote B already includes GST, it is about ₹62,000 cheaper than Quote A. If GST is extra on Quote B too, it becomes ₹6,72,600, about ₹40,000 dearer. The headline prices point one way; the tax line can point the other.

Before choosing, get both quotes to state the same things in writing: the GST, delivery and installation, the AMF panel, the battery, the warranty and the first-year service.

Who makes them

Kirloskar Oil Engines, Cummins India, Greaves Cotton and Mahindra Powerol all sell CPCB IV+ gensets through dealer networks. The listed makers' latest results are on their pages, such as Kirloskar Oil Engines, and side by side on the compare page.
