Diesel generators have been all the rage for the past few years owing to their fuel efficiency, durability and versatility. Catering to both commercial and residential needs, no wonder they’re selling like hotcakes.
But while buyers are pressing more on features of these generators, one major factor goes unnoticed — cost. It’s not just the final price of the equipment you’ve to look into, but the installation, operation and maintenance expenses as well.
So, if you’re wondering, “how much does a diesel generator cost”, here’s a definite answer to it.
Top-brand Diesel Generators with an Average Cost
The market for diesel generators in India is as diverse as the country itself. There is a myriad of options available with various features to suit your requirements.
Competition and branding are significant criteria in deciding the cost of any generator, given its remaining characteristics are similar.
Below are the top-brand diesel generators with their most-preferred power ratings and average costs.

With various models under different power ratings, they offer coverage plans to satisfy your needs and budget.

Cost to install a generator
Besides the Genset cost, you’ll also have to consider the installation expenses including registration, other equipment, and fuel.
Every state has its own set of guidelines for registering a diesel generator set and acquiring a license. Thus, consult your manufacturer before making the purchase and they’ll guide you throughout the entire procedure.
The processing fee might differ depending on your region. The license-approving authority also changes with the voltage class of your generator. Therefore, ensure you’re crystal clear about all the permits required and include their charges in your budget.
The Genset needs to rest on a clean, load-bearing and vibration-isolating surface. Installing concrete pads for diesel generators is a crucial step to facilitate smooth and hassle-free working.
You can either purchase a pre-cast concrete pad along with the Genset from your manufacturer or have it made on-site. For flood-prone areas or other issues, raised pedestals are best to keep the generator safe and free from any foreign particles.
To cut down on expenses, you can also conduct online research and build your DIY custom concrete pad.
Fuel consumption is another factor that will affect your post-installation expenses to a great extent. The table below provides a rough estimate of how much diesel you’ll need under various possible circumstances.
