Future of Diesel Generators: Is it a Stay for Future Generation or not?

Updated: Nov 22, 2021

Diesel generators are the most reliable solution for temporary or continuous power. Because of their all-rounder, measurable and weather independent operation. Following quite a few years of volatility and limited demand pushed with the aid of falling stock prices. The years 2017 & 2018 has been a return of profits for most producers and retail providers.

Despite this strong performance, more strangely stringent emission regulations, environmental concerns, and fluctuating fuel pricing can make a compelling case for Gensets hybridizations. Approaching report Diesel Generators Set Future Development and Alternative Technologies 2019-2029 examine the future market in the growing’s consent use of natural gas generators and the different alternative low.

Even though the world is in a big need for efficient energy sources and diesel generators could be a great solution. They come under serious fire, as an effect of regulation on every form of the climate-altering agent. Basically, they’re being directly threatened by environmental protection groups and government regulation. Because of their emission. It really does not matter how helpful they are for various industries, as long as they create an increasing amount of air and noise pollution.

Considering this aspect, along with the increasing technical progress in the domain of renewable energy and the decreasing costs. People claim that it won’t be long until the generators will completely disappear. They were recently stood against renewable energy despite this comparison not being fair. From a technical point of view, renewable energy is a source of grid power, while it uses diesel generators for backup power.

Regulatory Emission Controls

Regulatory emission controls are one of the most important factors of the market drivers. Forcing OEMs to invest in expensive exhaust after-treatment technologies and passing these increased costs on their customers.

With Stage V emissions management being phased in over the next 2-3 years. The cost of renewables and energy storage continues to fall. A tipping point for many end-user applications is conceivably insight.

In recognition of this, the key diesel generator stakeholders are adapting their business models and expanding in new directions.

Diesel Genset and Sustainability

The diesel generator engine uses the same four-stroke cycle as a petrol engine. But with two major differences involving the air-fuel mixture and injection systems. In the diesel engine, it compresses only air in the cylinder instead of an air-fuel compound.

Once the diesel fuel is injected into the cylinder, it immediately vaporizes and involuntarily ignites.

Modern diesel generator engines use direct-injection fuel-delivery systems, as the use of computerized engine management systems can closely control them.

In generic, the fuel efficiency of a diesel generator engine is higher than that of a petrol engine. This is primarily because the combustion temperature within a diesel generator engine is higher than in a petrol power unit. This increases the engine’s efficiency for a perfect heat engine.

The higher combustion temperature also leads to different exhaust emission profiles between vehicles with a petrol engine and a diesel engine. In addition, although diesel fuel has almost the same energy content per kilogram as petrol. It is denser and contains more energy per litre.

Petrol and Diesel Vehicle Energy Efficiency

In a diesel generator engine, 32% of the heat energy delivery to the crankshaft. Whereas in a petrol engine only about 24% becomes delivered. It delivers this kinetic energy to the wheels via the mechanical drive-train. Energy is ‘lost’ for friction between the transmission components to the aerodynamic drag of the vehicle.

As a result, in theory, only about 24% of diesel fuel’s energy ends up being used for moving the car; with petrol. This figure is only 18%. The actual values found vary enormously with the vehicle type and with the driving conditions. ICEs are inefficient in slow stop/start urban motoring and in situations of high acceleration; they work most efficiently running at a constant speed.

If we consider how the fuel’s energy is used to move the payload (as opposed to the whole vehicle). The situation is even worse. Only 1–2% of the fuel’s energy use to move the vehicle’s occupants.

Why Diesel Generators May Remain Viable

With a realized figure estimated at 3,000 reliable, continuous hours of sunlight each year. India is well-positioned to be one of the most innovative markets for the adoption of widespread solar power for primary electric power generation. It matches this realization with the hottest trend in power, going off-grid.

This new dynamic connects new solar systems with the superior storage and a tried-and-true partner in power generators–a diesel ‘Genset’. Known as a microgrid, the dynamic system integrates renewables, storage capacity, and backup industrial generators in an efficient and sustainable manner. Thanks to these microgrids, living lightly off the grid can happen today and it gears most countries dependable on such source of power, lead the way.

For many communities around the world, access to reliable electricity supply has been a transformative journey. It has enabled a higher quality of life whilst contributing to economic growth. For many developed areas, it has promoted by the use of diesel generators.

The high risk of serious power outages

The numbers seem to show that modern weather is becoming more severe and unpredictable. Including the amount of rainfall, wind speeds, the number of storms, and the cost of damage. Even without the threats from nature. According to the National Weather Advisory Council, the power grids are woefully unprepared for a “catastrophic power outage” from space or air attacks and infrastructural damage. Micro-grids should become more popular considering these threats.

The fragile state of the global economy

During the economic downturn, it naturally forces companies and individuals to find the cheapest goods, with environmental concern for much longer a luxury. That being the case, consumers could be averse to changing their energy production systems if a global recession strikes, which many analysts are predicting. Sticking with time-tested kva Generator’s, even over renewables that can save money over the long-term, may be considered the safest play.

Worldwide Power Products Prediction

We envision two paths for the future of diesel generators. In India, Diesel Generator will remain relevant, though highly regulated, for several years. Beyond that, it seems likely that given

a) The pace of technology and

b) Urging from environmentalists.

We choose to favour diesel generator buy today. Backup power generators are essential for many industries–businesses and governments will not step away from the definite security of diesel generators.


Several major manufacturers in the country offer diesel generators with power ratings starting from 2.5 KVA going to 3750 KVA. Each of them has carved out a niche for themselves operating in the specific power rating segment they are proficient in.

With implementing GST, these manufacturers see a higher role for themselves and are taking steps to cater to the increasing demand expected from huge investments in infrastructure soon. Also, you will get a better understanding of how a diesel generator works.

Generator companies in the unorganized sector, and localized generator companies, also offer custom-built generators with facilities and features that may not be easy for larger manufacturers to match.

However, large manufacturers don’t see these small generator producers as rivals. But anyway, they will have an important role to play in the expected boom in the building and construction industry.
