Power Ratings include Low-Power Generator, Medium-Power Generator, and High-Power Generator

The Indian diesel generator market can be segmented according to power ratings into low-power generators, medium-power generators, and high-power generators.

Low-power generators are the most widely used generators in the market, owing to their low cost compared to the higher power-rated generators. The power rating of these generators ranges below 75 kVA. These generators are widely utilised in the commercial and residential sector as a backup power source for air conditioners, refrigerators, and water pumps, among other appliances.

The high-power generators are expected to experience the most growth during the forecast period owing to the housing and infrastructure development projects launched by the government. Their power rating can range from 75-375 kVA.

The high-power generators are mostly used for long continuous operations and large construction sites. High-power generators are installed for power supply in off-grid remote areas, as it is not practicable to provide direct grip power to several remote places.

Medium-power generators are used for smaller constructions like building single houses, low-rise apartments, and offices. This segment is expected to have a steady growth and aid the growth of the Indian diesel generator market.

Mobility includes Portable and Stationary

The stationary generator segment is leading in the Indian diesel generator market as technological advancements have enabled many useful functions. Companies are launching new generators with increased security and automatic start-up functionality during a direct power outage.

The rising industrialisation, growing population, and developing economy have raised the energy demand exponentially. Compared to portable generators, stationary generators are much safer and quieter. The technological developments allow them to operate and shut down properly, minimising human error.

The portable generators are significantly less expensive than stationary generators and can be used as an emergency power backup source. They are generally used as a power source during outdoor activities like camping and others. Although, they are not the most preferred backup source for households as they are less secure and produce more noise compared to stationary generators.

Cooling systems in the India Diesel Generator Market include Air Cooled and Liquid Cooled

The air-cooling system is the most common in-home appliances as they tend to come at affordable prices. They require less maintenance and are used in lower power output generators. Air-cooled generators are not suitable for high power generation as they are less efficient in cooling when compared to liquid cooling.

Liquid-cooled generators are used in higher power-output generators as they are better at reducing the amount of heat produced in large engines. They are priced higher than the air-cooled generators and require frequent maintenance. The market for liquid-cooled generators is expected to show rapid growth, owing to their heat management and consistent power generation.

Diesel Generator find Applications in Standby Backup Power and Peak Shaving

The main applications of diesel generators include standby backup power and peak shaving. The generators are most used as a backup power source. The generators are increasingly getting efficient and advanced, they automatically start within seconds of a power outage to generate and transfer electricity. The market for this application is proliferating due to the rising infrastructural development and spending power among people in India.

Peak shaving in generators is utilised to reduce electrical power consumption during periods of high-power demand. During this period the generators are utilised for a short period of time to reduce the amount of direct power consumption. This method allows consumers to save a significant amount of money.

Diesel Generators Find End-Uses in Industrial, Commercial, and Residential Sectors

Diesel generators are the go-to option for power backup in manufacturing plants. They are widely used for mining operations all around the world, as they can easily be used in remote places and in extreme conditions. Diesel is also less volatile than other alternative fuels like gasoline, making it a much safer option during various heavy-duty activities.

With the increasing digitisation of the commercial industry, power loss can be a major detriment for the business. A diesel generator can enable companies to get instant power backup and keep the business running. The end-users in this segment are offices, food stores, and data centres, among others.

The residential use of generators is generally for power backup, and among other fuels, diesel is the most preferred, owing to its less volatile nature. They are also used for outdoor activities, and recently people have started to use generators on occasions that increase the power demand, to reduce electricity bills. The rising end-uses are likely to bolster the growth of the Indian diesel generator market.
