Generators & Engines

Boosting power


Most of the major suppliers of diesel engines and generators in India have been continuously upgrading the design of their products. With projects now gathering frenetic pace the degree of competition in 15 – 75 kVA and 75.1 – 375 kVA segments is expected to increase considerably. Rohan Ambike writes about the changing scenario of the generators and engines market.




The growing infrastructure sector as a result of various projects, the rise of new industries across the country and the paced up business environment has increased hopes that the genset market in the country is going to grow. The rise of telecom towers in the country is another segment that has propelled the growth of the genset market. A recent report suggests that the diesel genset market in India is set to grow at a CAGR of 5.41 per cent during 2018-23. Experts also point out that the continuous power in manufacturing sector was one area which can be the key driver for the entire genset market in the country. Major infrastructure projects viz Delhi-Mumbai Industrial Corridor and Vizag-Chennai industrial corridor in line with state run companies and private players seeking to expand manufacturing base is propelling the growth of the genset market in India.




In market terms, the generator sales market is estimated to reach $ 20.93 billion in 2018 and $ 27.24 billion by 2023. The prominent usage of generators will be for standby, prime, continuous, and peak shaving applications, mostly in various end-use sectors such as industrial, commercial, and residential. Additionally, the growing demand for uninterrupted and reliable power supply is one of the main drivers for the generator sales market.




India currently suffers from almost 15 percent peak power deficit which is hampering growth of all sectors in the economy, ranging from manufacturing to services sector, health and hospitality, and construction and infra sector. Almost each and every organization needs consistent power supply, as data loss can be more expensive than the capital expenditure required for backup power equipment. Therefore, it is expected that the demand for diesel generators will grow in the coming years.




Growth areas


The increase in the power deficits and the growing industrialization in the major southern cities of Bangalore, Hyderabad and Chennai has increased the need for gensets. Additionally, the other industries that are in search of gensets are —manufacturing and auto component industries in Tamil Nadu, information technology in Karnataka, bio-technology and pharmaceutical businesses in Andhra Pradesh and tourism and general engineering in Kerala and Puducherry.




Industries such as iron and steel, automobile, chemical and petrochemical, jewellery, textiles, cement and pharmaceuticals are another area that is a potential market area for the genset and the engine industry. Though there is a vast reduction in the rate of power deficit in the western region year-on-year, reports suggest that the demand for gensets has not reduced as they are the backup power source for many industries. The states like Maharashtra are home for industries that cater to the general engineering, automobile, chemical, pharmaceutical, textile and IT sectors. Similarly, the power deficit in Gujarat is also declining. However, the demand for diesel gensets is still growing due to the booming construction sector. The presence of large refineries and petrochemical complexes in this region requires reliable standby, emergency and mobile power that continues to boost the demand.




Continuing Demand


However, in a different sense, private power generators carry great weight – to be read as demand – in several places across India with no stable electricity access. The demand for electrical power is on the rise and experts anticipate a global consumption in the range of 36 to 82 PWh by the year 2050. What is encouraging about this trend of power deficiency for existing engine and generator manufacturers is that the market is expected to grow by 5.4 percent each year till 2020.




In their latest research study, “India Diesel Genset Market Outlook 2018”, RNCOS analysts have identified growth in the diesel generator market on the strength of the rising demand for power back-up systems in the country. In 2013, the Indian diesel generator market grew 9.5 per cent compared to the previous year. Further, as per the assessment the Indian diesel generator market (from 5 to 100 KVA) is anticipated to grow at a CAGR of around 11 per cent in value terms during 2014-2018. The Indian diesel generator market has largely been occupied by medium range (20 to 62.5 KVA), accounting for nearly half of the total diesel generator market. With rising power cuts and supply shortages the huge growth witnessed in the Indian diesel generator market has remained a constant. Gensets still remain the main source of power for housing, construction projects and as backup demand from IT companies, data centres, cinema halls, multiplexes and malls continues to grow. Naturally therefore, the demand for diesel generators is expected to grow in the coming years.




Sector segments


The Indian diesel genset market is broadly classified into four segments on the basis of kVA rating: low (5-75 kVA), medium (75.1-350 kVA), high (350.1-750 kVA) and very high (750.1- 3000 kVA). Low-rating diesel gensets constitute a major share of the market, and are used in the telecom sector for backup power in grid-connected areas and also as a main power source in off-grid areas. India is the second largest mobile phone market in the world with 500 million users and 700,000 telecom towers, which require continuous power supply - on average, the country’s telecom tower network consumes over 11 TWh annually, and this is likely to increase to 17 TWh by the end of this year.




The global market for diesel gensets is largely dominated by Asia-Pacific due to rapid urbanization and industrialization in this region, with China and India emerging as the largest revenue contributing countries in the region’s diesel genset market. During the forecast period, diesel genset market in Middle East & Africa and South America is expected to grow at the fastest rate, driven by strong market growth in countries such as Brazil, Argentina, Saudi Arabia and the UAE. Globally, power demand is increasing rapidly, while supply is not growing at the same pace, thus creating huge power deficit in many parts of the world. Consequently, the demand for power generation equipment such as diesel generators continues to increase worldwide. Poor power infrastructure and unreliable grid power supply have been largely responsible for increasing frequency of power outages, which is likely to boost the demand for diesel gensets across the globe. Rising demand for mobile diesel gensets and biofuel based diesel gensets is also expected to benefit the diesel genset market.




According to recent media reports, the Telecom Regulatory Authority of India (TRAI) wants Telcos to switch to renewable sources of power as this would save millions of litres of diesel and in turn millions of rupees per year. Of the total number of towers, 10 per cent have a regular power supply, and for the rest their power is supplied by diesel gensets. The medium rating of diesel gensets is the second largest category used in India. However, demand for these machines is anticipated to decline due to its shrinking application in the telecoms sector.




In India, gas gensets market is still at the nascent stage, and the market is being propelled by the low cost and eco-friendliness of natural gas. By 2025, according to Ministry of Petroleum & Natural Gas (Government of India), natural gas will contribute 20percentage in the country’s energy mix. Moreover, Central Pollution Control Board (under the Ministry of Environment & Forests, Government of India) has laid out various norms for regulating the level of harmful emissions from diesel gensets, which is also expected to positively influence the gas-gensets market in India.




On the basis of rating, the country’s gas gensets market has been segmented into four broad categories, namely, low (1kVA-75kVA), medium (76kVA-350kVA), high (351kVA-750kVA) and very high (more than 750kVA) gas gensets. Among these gas gensets categories, medium (76kVA-350kVA) gas gensets segment is anticipated to dominate the country’s gas gensets market over the next five years on account of their wide acceptance across industrial and residential sector. Region-wise, West India dominated the gas gensets market in 2014, and the region is forecast to maintain its dominance during 2015 – 2020.




Green Pastures


The residential and manufacturing sectors dominate the market, and account for more than 52 per cent of the market share during 2014. Owing to the boost in real estate construction projects and anticipated rise in foreign investments in newly launched smart city projects in India, the demand for diesel gensets is expected to grow through to 2020. The growing demand for uninterrupted power supply from various manufacturing facilities such as automobile and auto components is also expected to propel market growth over the course of the next five years. The ‘Make in India’ campaign would propel the demand for diesel gensets over the next six years immensely. Higher voltage DG sets required by high rises, hotels, educational institutes, and hospitals, among others seem to be rising in demand.




A number of companies have introduced higher capacity engines in the market that will cater to industries like the marine, construction equipment, cranes, forklifts, tractors, among others. Emission norms such as the Euro 6 will enable the demand for engines to raise significantly. With the introduction of new-range of products that will cater to both domestic and international markets, genset companies can expect to achieve nearly 40 per cent of revenues from its exports. Other major end users of diesel gensets include off-grid areas and agriculture, mining and BFSI sectors.




India being the second largest mobile phone market in the world with 500 million users and 700,000 telecom towers requires continuous power supply and the country’s telecom tower network is likely to consume over 11 TWh annually, and this is likely to increase to 17 TWh by early 2017. 10 per cent of the towers have a regular power supply, the rest is catered to by diesel gensets. However, Department of Telecommunications (DoT) has mandated the usage of renewable energy source to power telecom towers, which can affect the market for low rating diesel gensets.




The use of diesel gensets in telecom sector is currently declining due to players shifting towards using renewables sources of electricity and hybrid gensets, as per TRAI regulations. Rising concerns over carbon emissions are augmenting adoption of bio-diesel gensets in the country from various end user segments.  Growth in demand for diesel gensets from the manufacturing sector is fuelled by the booming auto component industry. India islikely to become the second largest steel producer in the world by the end of this year. This industry requires continuous power supply for running processing units, machining, resin moulding, pressing, welding and assembling.





Adhering to emission regulations is a critical element for Genset manufacturers today and advanced technological solutions are being adapted for combustion optimization. Higher fuel system pressure result in improved in-cylinder combustion process and air handling, after treatment, filtration and control systems has undergone a modification. This change in technology and material will impactgenset prices which are likely to go up 15-20 per cent. So manufacturing of energy efficient generators need to counter the hike in fuel prices.




The major suppliers of diesel generators sets in India have been continuously upgrading the design of their products to conform to global emission standards. This has necessitated investments and exchange of technology knowhow with global engine suppliers.




With projects now gathering frantic pace the degree of competition in 15 – 75 kVA and 75.1 – 375 kVA segments is expected to increase considerably with several new players – domestic and international – venturing into the market. This is an important time for the participants in this engines and generators space and to secure their positions in the market revised service strategies offering additional value will have to be introduced.
