Which amongst your products can provide energy to the cement manufacturing process?
In recent times, solar energy has undoubtedly emerged as a powerful and eco-friendly source of electricity making it suitable for various industrial applications. The cement production sector,
known for its high energy demands from carbon-emitting sources, stands as an ideal sector for our groundbreaking solar solutions to create a significant transformative impact.
Our highly compatible On-Grid Solar System is engineered to meet the power demands of the cement manufacturing plant by tapping into the abundant and clean resource of solar energy, ultimately leading to reduced energy costs. This not only promotes sustainable manufacturing practices but also enhances cost-effectiveness. By harnessing the abundant solar energy, we offer sustainable and adaptable solutions that are propelling the cement production energy towards a more sustainable future.

Cement production is an energy-intensive. Can solar energy support the process and make it sustainable?
Absolutely! Cement manufacturing indeed requires a significant amount of energy, which comes from carbon-emitting sources. However, by integrating Servotech’s on-grid solar system, the cement manufacturing process can be supported with clean and renewable energy. This sustainable energy source not only reduces the carbon footprint but also lowers operational costs, making the entire process more environmentally friendly and economically viable.

Tell us about your process of supplying energy to cement plants.
Our highly efficient On-Grid Solar System is designed to provide solar energy to cement manufacturing plants seamlessly. The process begins with the installation of solar panels, which capture sunlight and convert it into electricity. The energy generated is then fed into the plant’s electrical grid. This solar-generated electricity effectively powers various operations within the cement manufacturing process, reducing the plant’s reliance on conventional energy sources and lowering its electricity costs.
This transition to solar energy not only makes cement production more sustainable but also contributes to reduced operational expenses, ultimately benefitting the environment and making the entire process cost-efficient.

How is the impact of using solar power as an energy source compared to carbon-emitting energy sources?
The environmental benefits of solar power are profound. Unlike traditional energy sources that rely on fossil fuels, solar energy is clean, renewable and emission-free. When integrated into the energy supply for cement plants, solar power significantly minimises the use of fossil fuels, which are finite resources and major contributors to greenhouse gas emissions.
By reducing reliance on carbon-emitting energy sources, solar power contributes to a cleaner and healthier environment. This transition to cleaner energy not only mitigates climate change but also enhances air quality, thereby creating a more sustainable and environmentally conscious future.

Which standards and compliances do you adhere to?
We place paramount importance on adhering to industry standards and regulatory compliance throughout the manufacturing and installation of our solar systems. During the manufacturing process, rigorous quality checks are conducted to ensure the efficiency, durability and optimal functioning of our products.
When it comes to the installation of our solar systems, we take meticulous care to ensure proper mounting and positioning, maximising their exposure to sunlight. Our manufacturing and installation procedures strictly adhere to the standards established by reputable organisations, including the National Electric Code, IEEE, BIS, ISO and IEC.
Furthermore, our solar products are MNRE-approved. By complying with these standards,
we ensure robust, sustainable, and safe solar power installations.

What are the major challenges that you face in the supply of renewable energy?
The supply of renewable energy faces several significant challenges. Finding a suitable location to facilitate installation is one of the major problems. Every area be it urban or rural comes with its own set of challenges, in this case, finding a location that supports smooth installation can get a little tricky.
Intermittency is a primary concern, as sources like wind and solar are weather-dependent, requiring energy storage solutions to ensure consistent availability. Infrastructural limitations of the grid hinder the efficient distribution of renewable energy from remote locations to urban areas. Additionally, the high
upfront costs of renewable technologies can deter investment. Regulatory and policy uncertainties also impact growth.
Finally, environmental concerns, such as land use and wildlife disruption, need careful consideration. Addressing these challenges requires advancements in energy storage, grid modernisation, supportive policies, and innovative solutions to ensure a reliable and sustainable renewable energy supply and Servotech is actively working towards surmounting these barriers, paving the way for a sustainable future powered by solar energy.

ICRA Sees Steady Cement Demand Growth Ahead

Volumes seen rising 6–7 per cent in FY27 on infra push

Published

India’s cement industry is expected to record steady growth over the coming years, with cement volumes projected to expand by 6–7 per cent in FY27, supported by sustained demand from the housing and infrastructure sectors, according to a report by rating agency ICRA.

The agency said the sector is likely to maintain healthy momentum after registering growth of 6.5–7.5 per cent in FY26, despite a higher base in the second half of FY25. Cement demand remained strong in the current financial year, with volumes increasing by 8.5 per cent during the first eight months of FY26, driven by robust construction activity across regions.

ICRA expects demand to strengthen further in the second half of FY26 as construction activity accelerates after the monsoon. Continued government focus on infrastructure spending and the possibility of a reduction in goods and services tax on cement are also expected to support demand through FY26 and FY27.

Against this favourable demand backdrop, cement manufacturers are continuing to expand capacity through both organic and inorganic routes to strengthen their market positions. The industry is estimated to add 85–90 million tonnes per annum of capacity during FY26–FY27, including around 43–45 million tonnes per annum in FY26 and a further 42–44 million tonnes per annum in FY27.

Commenting on the outlook, Anupama Reddy, Vice President and Co-Group Head, Corporate Ratings at ICRA, said sector profitability is expected to improve significantly in FY26, supported by better pricing and higher volumes. Operating profit before interest, depreciation, tax and amortisation per tonne is projected to rise to around Rs 900–950 per tonne in FY26, compared with Rs 810 per tonne in FY25.

However, ICRA expects some moderation in earnings in FY27 due to rising input costs. Operating profit per tonne is estimated at Rs 880–930 in FY27, as costs related to pet coke and freight are likely to increase and remain influenced by global crude oil prices and geopolitical developments.

On a regional basis, North and Central India are expected to report capacity utilisation levels above the national average, while the southern region may continue to see relatively moderate utilisation due to existing capacity overhang. ICRA noted that recent merger and acquisition activity in the southern market has helped large players strengthen their regional and pan-India presence.

Overall capacity utilisation for the cement industry is projected to remain stable at around 70–71 per cent in FY27, broadly in line with FY26 levels, albeit on an expanded capacity base.
