The cement industry has been going through consolidation phase with large Indian cement players preying on smaller ones and foreign cement majors acquiring controlling stake in Indian majors. Prakash Patil looks at the M&A scenario and what it holds for the future of cement industry in India.It’s mergers and acquisitions season in the Indian cement industry and the latest big ticket deal is the acquisition of 51 per cent controlling stake by Irish cement major CRH in the two 2.4 MTPA plants of the Jaypee Group in Gujarat. A buoyant trend in prices could reportedly fetch the Jaypee Group at least $160 per tonne as replacement value, as it puts on the block its hived-off plants in western (2 units of 2.4 MT each) and southern India (1 unit of 5 MTPA). The deal for the two 2.4 MTPA plants is reportedly valued at Rs 4,200 crore. However, as Jaypee Group has its third plant with a capacity of 5 MTPA in Andhra Pradesh and the three plants would be valued at about Rs 9,000 crore. For CRH, this will be the second acquisition in India. The company had forayed into India in 2008 with the acquisition of 50 per cent stake in Hyderabad-based cement producer My Home Industries, which had an installed capacity of 4.2 MTPA.The latest CRH-Jaypee Group deal is an indication of the churning the Indian cement industry is going through over the last decade or so. The big fishes are on the prowl to gobble up smaller fries in the business and considering that there are 139 large cement plants and 365 mini cement plants in the country currently with 40 major and mid-size players having pan-India presence, the opportunities for acquisitions for the large cement players are enticing. And, it’s not just the small fries that are on the radar of the big players, even some of the biggest cement companies have been taken over in the past and many more are being wooed. After all, the cement business of Jaypee Group being acquired by CRH makes Jaypee Group the third largest cement player in India after UltraTech and Ambuja Cements.The big ticket dealsApart from the latest big ticket deal between the CRH-Jaypee Group, there have been quite a few large takeovers since 1999. When Gujarat Ambuja Cements (GACL) picked up 7.2 per cent stake in India’s then largest cement manufacturer ACC at a price of Rs 370 per share when the market price hovered around Rs 240 per share from the Tatas in December 1999, it created sensation. Later in 2000, GACL acquired the balance 7.2 per cent from the Tatas to become the largest shareholder in ACC. But the twist to this tale came when Swiss cement major Holcim picked up 14.8 per cent stake in Gujarat Ambuja Cements (later to merge with Ambuja Cements Eastern to become Ambuja Cements) for Rs 2,100 crore through the creeping acquisition route and later picked up another 20 per cent stake for Rs 2,400 crore. Subsequently, Holcim hiked its stake in Ambuja Cements to over 50 per cent, thereby acquiring complete management control over Ambuja Cements. The Holcim transaction and valuation provides an excellent indication of the extent to which investors and strategic players are ready to buy the India growth story. In 2005, Holcim acquired stake in ACC at an enterprise value (EV) of $111 per tonne and the next year Holcim acquired stake in Ambuja Cement at an EV of $193 per tonne. In 2007, Holcim again increased its stake in Ambuja Cements at an EV of $301 per tonne!With this acquisition, Holcim also acquired management control over ACC as Ambuja Cements had hiked its stake in ACC to more than 50 per cent. So, Holcim upped the ante for other global cement companies by acquiring majority stake and management control over two of India’s largest cement companies.Lafarge, the French cement major, got late into action in the M&A space and decided to take the acquisition route to fast track it cement business in India. The company declared in 2010 that it was open to consolidation in India and, according to Bruno Lafont, Chairman & CEO, Lafarge, the timeframe for acquisitions was the next five years. "We see consolidation happening (in the cement industry) in India in the mid term period. We are confident of our ability to deliver our investments in India and are open to seizing new opportunities, be it consolidation or greenfield projects," said Lafont while inaugurating the clinker line at Lafarge India’s cement plant in January 2010 at Sonadih in Chhattisgarh. The company entered the Indian market in 1999 with the acquisition of Tata Steel’s cement plant. This was followed by the purchase of the Raymond Cement facility in 2001 and the acquisition of L&T’s concrete business in 2008.The takeover of L&T’s cement business by Grasim Industries in June 2003 also created buzz in the market since this takeover catapulted Grasim Industries (later its cement division being merged into UltraTech Cement) from the third position to the numero uno position in India. After the takeover, UltraTech’s installed capacity went up from 13 MTPA to 31 MTPA. Grasim Industries had to shell out Rs 2,200 crore over a period of three years for a majority stake in Ultratech Cement. Today, UltraTech maintains its leadership position with an installed capacity of 52 MTPA, with Holcim at the no. 2 position with combined capacity of 45 MTPA through ACC and Ambuja Cement.These are just a few samples of big ticket deals that have happened in the cement sector in India since late nineties. There have been many more big and small takeovers and mergers by domestic players since mid-1990s and by foreign players since late-1990s (see box). According to the data published by the Department of Industrial Policy and Promotion, the cement sector attracted foreign direct investments (FDI) worth US$ 2.62 bn between April 2000 to May 2012, which is an ample indication of the fact that the cement sector has been attracting foreign investors in droves.The key M&A triggersClearly, the cement biggies have gone on a shopping spree since during the last decade or so. And not without reason. There are compelling reasons why domestic and foreign cement majors appear to be so bullish on India. "Major reasons for consolidation were excess capacity and entry of foreign players who wanted a pie of untapped Indian market…Apart from above two reasons, another factor that is leading to consolidation is the rising cost of greenfield capacity which also tends to have longer gestation period. Existing players are eyeing companies who are unable to meet rising cost of raw materials due to increasing imported coal prices. On the other hand, the top players who want to spread their reach are tapping such companies as it saves on time factor of greenfield capacities," says Alok Sanghi, Director, Sanghi Industries.
Commenting on the reasons for consolidation, Jailesh Dalal, Director, JAYCEE Buildcon (India), says "The Indian cement industry is fragmented and large domestic and international players would try to consolidate their position going forward for geographical diversification, concentrated focus on operational efficiency, challenges in acquiring land/limestone resources, exit of smaller players and divesture of cement businesses by diversified groups."Now, let’s look at each of these reasons why Indian cement industry is passing through the consolidation phase.Overcapacity

During 2007-12, cement producers added capacity to the tune of 150 MTPA, thereby almost doubling the total installed capacity to 303 MTPA in FY2012-13. According to a report by research firm RNCOS, "It is anticipated that the cement industry players will continue to increase their annual cement output in coming years and the country’s cement production will grow at a compound annual growth rate (CAGR) of around 12 per cent during 2011-12 to 2013-14." According to projections, by 2017 the total capacity nationally would add up to 470 MTPA.The increase in capacities by many of the Indian companies was in anticipation of demand from the infrastructure sector which failed to materialise. In a situation where demand fails to keep pace with supply, the capacity utilization rate is bound to decelerate. The capacity utilisation rate for the cement industry in India has dropped from 93 per cent in FY2006-07 to 75 per cent in FY2011-12. The fall-out of such overcapacity situation is that the cement prices are likely to come under downward pressure which would make survival difficult for smaller cement companies with capacities less than 1 MTPA and therefore vulnerable for takeover. However, the fact that cement majors have built up capacities in advance is an indication that these companies expect demand for cement to remain firm due to construction activity, which is expected to gather momentum due to government’s policy to boost investments in infrastructure.Infrastructure PotentialIndia’s high housing and infrastructure deficits points to the huge potential for development of housing and infrastructure. The cement sector will benefit hugely as and when the momentum in housing and infra development picks up. This potential for development has been attracting major players in hordes from across the world. The demand for cement, being a derived demand, primarily depends on the industrial construction, real estate business, construction activities and investments in the infrastructure sector.Currently, the housing sector consumes 55-60 per cent of cement produced in India and this is expected to change in the next few years when the emphasis will shift on infrastructure development such as roads, bridges, airports, and railways, which will consume a significant percentage of cement produced in the country. The consumption of cement in agriculture is negligible today; but with a greater thrust on agriculture and the suggested ‘second green revolution’, this sector too will extensively use cement to build warehouses and other logistics.But instead of opting to set up cement plants themselves, it makes sense for the foreign players to take the acquisition route not just to make foray into India but also ramp up capacity quickly. The high potential for growth in demand for cement is amply evident from the fact that the per capita cement consumption in India was 230 kg in 2010, which is almost half of the global average of around 450 kg and way below the Chinese average per capita consumption of 1220 kg. Hence, domestic and foreign cement companies remain bullish on the prospects of cement industry in India.High capital cost & long gestation periodA cement plant is typically a capital intensive business and to establish a greenfield project takes about three years. The cost of setting up a greenfield capacity has reportedly shot up from $120 per tonne to $160 per tonne in just two years. Besides, the cement business has a long gestation period and, depending on the market situation, the break-even point may extend to three-four years at an operating level of 70-75 per cent. The high capital cost and long gestation period makes establishing a new cement plant an unattractive business proposition. Hence, established and large players may prefer to poach on the existing and established players to beat the competition and increase their market share. "The cement sector is slowly heading for a major consolidation as greenfield projects are becoming difficult to set up due to increased hassles in areas like mineral concession, land acquisition and related environmental and operational issues. This may lead the cement industry in India to be consolidated in the hands of a few major giant cement companies and only a few cement companies with single or smaller capacity plants shall continue to operate purely due to regional and local factors," says P K Ghosh, Chairman, Ercom Engineers.Entry barriers & cumbersome proceduresDifficulty in accessing limestone reserves, which is a key input in cement production, acts as a significant entry barrier for new entrants. To overcome this difficulty, takeover of companies with access to limestone reserves is the easiest route to crossing the entry barrier. No wonder, none of the foreign cement majors tried to set up a greenfield cement plant as prospecting for limestone reserves is a time-consuming process. Even if the limestone reserves are established, getting the mining rights, railway siding, etc. can reportedly take upto 7-8 years, with only 25 per cent chance of striking enough limestone reserves to last for the entire economic life-span of the plant. Hence, acquisition is bound to pick up further momentum as more cement majors enter the Indian market.The benefits of consolidationThe consolidation in the cement industry would prove to be beneficial both for the acquiring companies as well as for the cement industry. Some of the benefits that would ensue from consolidation are as follows:
Economies of scale
A large cement company enjoys the benefits of economies of scale. Mergers and acquisitions bring about consolidation of capacities which adds up the benefits of scale. The economies of scale enable the company to reduce the production costs so that it can reduce the cement price to maintain an edge over the competitors.Extended reach and increased revenuesWhen a company takes over the production and distribution facilities of another company, it immediately extends its geographical reach and increases its market share on account of expansion of the market for its product. The market expansion helps in ramping up the revenues of the company within a short span of time. The enhanced geographical reach may also result in substantial reduction in transportation costs which are quite high as cement is a bulk commodity.Technological upgradationThe new energy-efficient but capital-intensive "dry" production technology offers to the companies efficiencies that provide vital edge over the companies not deploying such technologies. Small manufacturers may not possess the requisite financial resources or production volumes to be able to afford the most efficient technology, which puts them at a competitive cost disadvantage. The entry of foreign players has led to technological upgradation and innovation in Indian cement industry. "Despite the fact that the technology used by Indian cement companies is among the best in the world, more innovation is required to ensure that cement plans are not only environment-friendly, but also low-cost in nature. M&As in last decade has helped Indian firms propel to global standards. Foreign firms who took over Indian firms have made most of the investments in India in the last decade for upgrading technology and raising capacity. With higher spend on technology, existing players are likely to focus more on ready mix concrete, bulk sales and blended cement to ensure improvement in quality as well as environment consciousness with sustainable construction," says Sanghi.The Road AheadGoing forward, the acquisitions space is going to get hotter, with lot of small and mid-sized cement companies up for grabs. Once the economies of scale kick in on account of consolidation, the cement prices are likely to remain competitive yet remunerative. This would benefit both the cement companies as well as cement consumers. Summarising the benefits of consolidation, Dalal says, "M&As would largely have a positive impact in the cement industry in India on account of value creation, economies of scale and cost efficiencies, operational and supply chain efficiencies, higher competitiveness, technology transfer, better research and development and high quality products, financial leveraging and optimization of profitability and increased focus on health, safety and environment. In the future as well, M&As would augur well for the industry as it would bring world-class technology, products and operational efficiencies into India." Sanghi too feels that M&As would be beneficial and says, "M&As in cement industry is likely to bring pricing power, improve profitability and reduce cost of branding for top players. Through M&As, top players would have higher vertical integration and locational advantage with respect to sourcing raw materials and market reach."Of course, there is always the possibility of major companies forming a cartel to keep the cement prices artificially high, but with the Competition Commission of India keeping a vigil over the production figures, capacity utilization and cement prices, the cement companies would be wary of indulging in such malpractices. Sanghi too dismisses fear of cartelization saying, "If there was (cartelisation) as is claimed, cement companies would not have reported losses in any quarter. Also, prices would have been same across the year, if there was cartelization. But every year, cement prices fall during monsoon because there is a slowdown in demand; while prices rise on and around Diwali due to surge in demand from real estate."To sum up, consolidation is good for the cement industry and there are sunny days ahead for the industry in times to come.

How does your Energy Performance Contracting model typically reduce power consumption in cement plants—e.g., MWh saved?
Our artificial intelligence-based DigiMine AI Pyro and Mill solutions developed specifically for the cement industry, supports our customers in improving their process stability, productivity and process efficiency. In Pyro, this is achieved by optimising fuel consumption (Coal / AFR), reducing Specific Heat Consumption and reduction in emissions (CO2, SOx and NOx) through continuous monitoring of thermodynamics in pyro and recommending set-points of crucial parameters in advance for maintaining stable operations.
Within the mill, this is achieved by improving throughput, reduce energy / power consumption and maintaining stable operations on a continuous basis. Our ROI-based value proposition captures the project KPIs like reduction of coal usage, increase of AFR, reduction of specific heat consumption (Kcal / Kg), reduction of specific power consumption (KWH / tonne), reduction of emissions, etc., by a specific percentage. This gives clarity to our customers to understand the investment vis-à-vis savings and estimate the recovery time of their investment, which typically is achieved within one year of DigiMine AI Pyro and Mill solutions implementation.

What role do digitalisation and motor monitoring play in overall plant energy optimisation?
Motors are being used extensively in cement production, and their monitoring play crucial role in ensuring continuous operation of applications. The monitoring system can automatically generate alerts for any anomaly / abnormalities in motor parameters, which allows plant team to take corrective actions and avoid any major equipment damage and breakdown. The alerts help maintenance team to plan maintenance schedule and related activity efficiently. Centralised and organised data gives overview to the engineers for day-to-day activities. Cement is amongst the top energy intensive industries in comparison to other industries. Hence, it becomes critically important to optimise efficiency, productivity and up-time of plant equipment. Motor monitoring and digitalisation plays a vital role in it. Monitoring and control of multiple applications and areas
within the plant or multiple plants becomes possible with digitalisation.
Digitalisation adds a layer on top of OT systems, bringing machine and process data onto a single interface. This solves the challenges such as system silo, different communications protocol, databases and most importantly, creates a common definition and measurement to plant KPIs. Relevant stakeholders, such as engineers, head of departments and plant heads, can see accurate information, analyse it and make better decisions with appropriate timing. In doing so, plant teams can take proactive actions before machine breakdown, enable better coordination during maintenance activities while improving operational efficiency and productivity.
Further using latest technologies like Artificial Intelligence can even assist operators in running their plant with minimal requirement of human intervention, which allows operators to utilise their time in focusing on more critical topics like analysing data to identify further improvements in operation.

Which of your high-efficiency IEC low-voltage motors deliver the best energy savings for cement mills or fans?
Innomotics India offers a range of IEC-compliant low-voltage motors engineered to deliver superior performance and energy savings, particularly for applications such as cement mills, large fans, and blowers. Innomotics has the complete range of IE4 motors from 0.37kW to 1000kW to meet the demands of cement industry. The IE5 range is also available for specific requirements.

Can safe area motors operate safely and efficiently in cement kiln environments?
Yes, safe area motors are designed to operate reliably in these environments without the risk of overheating. These motors have ingress protection that prevents dust, moisture ingress and can withstand mechanical stress. These motors are available in IE3 / IE4 efficiency classes thereby ensuring lower energy consumption during continuous operation. These motors comply with relevant Indian as well as international standards.

How do your SD Severe Duty motors contribute to lower emissions and lower cost in heavy duty cement applications?
Severe duty motors enhances energy efficiency and durability in demanding cement applications, directly contributing to lower emissions and operational costs. With high-efficiency ratings (such as IE3 or better), they reduce power consumption, minimising CO2 output from energy use. Their robust design handles extreme heat, dust and vibration—common in cement environments—ensuring reliable performance and fewer energy losses.
These motors also lower the total cost of ownership by reducing downtime, maintenance and replacement frequency. Their extended service life and minimal performance degradation help cement plants meet sustainability targets, comply with emissions regulations and improve overall energy management—all while keeping production consistent and cost-effective.

What pump, fan or compressor drive upgrades have shown approximately 60 per cent energy savings in industrial settings and can be replicated in cement plants?
In the cement industry, the primary high-power applications are fans and mills. Among these, fans have the greatest potential for energy savings. Examples, the pre-heater fan, bag house fan, and cooler fans. When there are variations in airflow or the need to maintain a constant pressure in a process, using a variable speed drive (VSD) system is a more effective option for starting and controlling these fans. This adaptive approach can lead to significant energy savings. For instance, vanes and dampers can remain open while the variable frequency drive and motor system manage airflow regulation efficiently.

As energy costs continue to dominate the cement industry, efficiency and sustainability are proving to be vital components. MM Rathi, Joint President, Power Management, Shree Cement, explains the company’s long-term strategy is focused on cutting emissions while powering growth with renewable energy solutions.

Energy efficiency has always been a cost-saving lever for the cement industry. Today, it is the backbone of sustainability and competitiveness. Cement manufacturers are under growing pressure to optimise consumption, diversify power sources and align with decarbonisation targets. Shree Cement has been at the forefront of this transformation, significantly scaling up its green power capacity and embedding advanced technologies across operations. In this exclusive conversation, MM Rathi, Joint President – Power Management, Shree Cement, shares insights on the company’s approach to energy efficiency, challenges in brownfield modernisation and long-term strategies for achieving net zero alignment.

What percentage of your total operational cost is attributed to energy consumption?
At Shree Cement, energy is one of the most significant components of production cost, accounting for nearly 30 per cent to 40 per cent of total operational expenses. Within this, thermal energy typically contributes around 20 per cent to 25 per cent, while electrical energy forms about 10 per cent to 15 per cent. The exact share varies depending on factors such as the fuel mix (coal, pet coke or alternative fuels and raw materials), the power source (grid-based or captive like solar, wind or thermal), raw mix quality, and regional fuel and electricity price variations. This makes energy efficiency and the adoption of sustainable power sources a key focus area, both from a cost and sustainability perspective.

How has your company improved energy efficiency over the past five years?
Over the past five years, Shree Cement has consistently invested in enhancing energy efficiency across operations. Our green power capacity, covering wind, solar and Waste Heat Recovery (WHR), has more than doubled from 245 MW in 2020 to 592 MW in 2025. All grinding units are now equipped with biomass firing facilities, reducing dependence on conventional fuels. From the project stage itself, we prioritise efficiency by selecting advanced technologies such as six-stage kilns with integrated WHR, CFD-designed plants, and equipment fitted with VFDs, centrifugal compressors and high-efficiency fans. We also review and upgrade equipment systematically, replacing fans, compressors, blowers, pumps, boilers and turbines with more efficient options. This continuous approach has reduced costs while significantly advancing our sustainability journey.
What technologies or practices have shown the highest energy-saving potential in cement production?
WHR stands out as one of the most effective solutions, offsetting a significant portion of electricity required for clinker production. Hot air recirculation has also proven highly beneficial in reducing heat losses. Additionally, regular energy audits help us identify opportunities for improvement and implement corrective measures in daily operations. Together, these practices play a critical role in optimising energy efficiency and driving sustainable operations.

What are the key challenges in adopting energy-efficient equipment in brownfield cement plants?
The biggest challenge is the significant upfront investment required for upgradation. Retrofitting existing facilities often involves complex civil and structural modifications, which add costs and extend downtime. Integration is another hurdle, as new high-efficiency equipment may not align seamlessly with older kiln systems, fans, mills or automation setups. These factors make the transition in brownfield plants more resource-intensive and time-consuming compared to greenfield projects.

How do you measure and benchmark energy performance across different plants?
We track key performance indicators such as specific heat consumption and specific power consumption for each unit, benchmarking them against internal and external standards. Thermal Substitution Rate (TSR percentage) is another critical metric, measuring the share of alternative fuels in the thermal energy mix. Internally, we benchmark performance across plants to encourage best practice sharing. Externally, we compare against national averages and align with the Bureau of Energy Efficiency’s PAT (Perform, Achieve, Trade) scheme, which sets Specific Energy Consumption (SEC) baselines and targets for cement plants. This multi-layered approach ensures continuous monitoring, improvement, and industry leadership in energy efficiency.

What role does digitalisation play in achieving energy efficiency in your operations?
Digitalisation is pivotal in driving energy efficiency at Shree Cement. IoT sensors integrated with SCADA and DCS systems allow real-time monitoring of parameters like heat consumption and energy use, moving beyond periodic reports. Our digital platforms consolidate plant data, enabling management to compare metrics such as SPC, SHC, kWh per tonne and kcal per kg across units in real time. This visibility supports data-driven decisions, faster corrective actions, and higher operational efficiency.

How do government policies and incentives influence your energy-saving decisions?
Government policies and incentives strongly shape our energy-saving decisions. The Perform, Achieve, Trade (PAT) scheme sets plant-specific SEC targets. Non-compliance incurs penalties, while compliance earns tradable energy-saving certificates. This ensures energy efficiency is both cost-driven and regulatory. Additionally, subsidies and viability gap funding for renewable energy projects in wind, solar and AFR co-processing help reduce payback periods and make energy-saving investments more viable.

What is your long-term strategy for aligning energy efficiency with decarbonisation goals?
Our long-term strategy aligns energy efficiency with India’s net zero 2070 goals. Key levers include improving efficiency, expanding green electricity, producing more blended cement, and increasing alternative fuel use. Today, more than 60 per cent of our electricity comes from green sources such as solar, wind, and WHR, the highest in India’s cement industry. Our blended cement products, which reduce limestone and fuel consumption, further lower emissions. These products are certified under the GreenPro ecolabel by CII, validating our sustainability practices and environmental standards.
