Rapid industrialisation is boosting the demand for diesel and gas generators. Diesel backup generators offer a lifeline in times of crisis. Considering the regular power outages in India, it poses hazards to public health and safety as critical services come to an operational halt. Blackouts in industrial areas can increase the risks to business operations, which may result in downtime and loss of revenue due to failure to carry out regular operations. In times of power outages due to grid failure, diesel backup generators aid in providing electricity to both residential and industrial end-users. Gas generators are expected to exhibit a steady growth rate due to the increase in demand from commercial and industrial sector. The availability of natural gas reserves is an important reason contributing to the growth of gas generators market in the region. Incidentally, this market also sees tough competition. We check how manufacturers of generators are pushing the envelope to offer environmentally-safe generators.
Modern day generators have improved their performance, capability and functionality in recent years. The Indian genset market has gone through a major transformation over the last one decade improving on power delivery, lower fuel consumption and controlled pollution levels. Higher use of electronics has ensured better controls and high level of system integration. “Quality of engines manufactured in India are now on par with those manufactured the world over and are more reliable and durable with reduced maintenance costs. As the power situation improves, Gensets are becoming more and more standby emergency power sources, the growth has been muted but improved economic activity will surely see the demand for generators going up in the near future. The industry is fairly mature and developments are predominantly focused on improving efficiency and reducing pollution levels,” says Sanjay Jadhav, President, Sterling Generators. Diesel generators have proved to be a boon in the commercial industries. Over the years, power generators have indeed improved drastically in a lot of ways. Recent developments like automated fuel injection have maximized the engine performance and power output. “Newer designs of diesel generators have moved from the age old analog controls to digital ones. These provide more precise measurements and real time status updates on generator status. Environment friendly, technological advances have made it possible to reduce noise and gas emission at a huge level. While sound attenuation pockets have helped in reducing noise, catalytic reductions have helped in reducing gas and fumes emissions,” says Aashim Ahuja, Director – Perfect Generator Technologies Pvt. Ltd.
In recent years the generator have become more fuel efficient courtesy the changes/modifications in the combustion chamber in the newer diesel engines have combustion chambers sized and configured to achieve maximum combustion rates. “The greater the combustion rate, the higher the power output and fuel efficiency and lower the exhaust emissions. Sound has also been a problem over the years with diesel engines; most people associate the diesel engine with high levels of noise. Recent advancements in sound attenuation materials and strategies have enabled engineers to reduce noise levels to a significant extent,” avers Sorav Narula, Partner, Tara Genset Engineers.

The industry focus has been on improving efficiency and reducing toxic pollutants through the exhaust systems. Mechanical engines are now getting more electronics built in for sharper control and better operational interfaces. DG sets can now be remotely monitored with GPS data logging systems and integration with the BMS systems. “We as a company have the technological knowhow to manufacture these systems including all types of control panels required. Continuous product development and close working with our customers and suppliers have ensured Sterling Generators to be a step ahead of others when it comes to execution of highly specialized and complex integration of large number of generators in a single project,” says Jadhav. In recent years, the generators have become technologically far more advanced than before, the engines are more fuel efficient, and they have lesser noise and vibrations leading to lesser wear and tear. “Introduction of software and digital based controllers to control and monitor the generator’s performance has resulted in better safety of the generators against faults like overloading, engine oil leakages or high temperatures etc. The CPCB (Central Pollution Control Board) has also played a pivotal role to shape the standards to be followed by the manufacturers in terms of air and noise pollution,” says Narula.
Alternate Energy Channels
Gas powered generators are being considered as an alternative power back up option in India however, diesel gensets are still the preferred choice primarily because of easy availability of diesel. Gas Generators are eco-friendly however, availability of gas at remote sites is a challenge. This can be addressed once the availability of gas improves across remote sites. Yashaswi Shroff, Director, Alcove Realty says, “technically, gas-powered generators are better than diesel generator because maintenance and pollution is relatively much lesser. Having said that, the initial cost of procuring the machine is high but running cost is low, thus it is profitable in the long run.” The gas powered generator market has been developing in recent years. As per analysts, global gas generator market is estimated to grow at CAGR of 8.01% between 2017 and 2021. This growth has been mostly propelled by stringent emission norms across countries and discoveries of shale gas reserves, and the ever increasing demand for power. Gas based generators have found favour among commercial and residential segments. As availability of gas improves people will switch to gas generators for better emission levels and where the power requirements are on a higher side. Ahuja adds, “undoubtedly, gas powered generator market has developed a lot in recent years. One of the most obvious benefits is that it is cleaner, less expensive and considerably efficient. At a certain level, they are effective in reducing costs when used at homes. Since natural gas is easily available in large cities through pipelines, storage of fuel becomes redundant.”
The fact that generators are critical backup measures and involves a key resource power, it is most important that after-sales service of generators is in place. Most manufacturers, including Sterling Generators, offer 24*7 support for existing Clients. Industrial generators, especially, requires regular service to operate at optimal efficiency. An effective after sales package would not only ensure effective repair, but the team to have ready access to spare parts as and when required. “Product support plays a crucial role in the overall buying cycle of a product.
