Tushar Kulkarni, Business Division Head- Solutions, Cement, Mining Minerals, Test Applications and Hydrogen, Innomotics India, discusses the evolving role of automation in cement business.

The cement industry is undergoing a transformative shift as it faces the dual pressures of improving operational efficiency and meeting aggressive sustainability goals. In this demanding environment, digitalisation, intelligent automation and AI-based optimisation have become critical tools for survival and growth. This exclusive conversation with Tushar Kulkarni, Business Division Head- Solutions, Cement, Mining Minerals, Test Applications and Hydrogen, Innomotics India, brings the focus on cement plant automation, energy efficiency and AI-powered transformation.

How does Innomotics’ CEMAT Automation system streamline cement plant processes?
Cement manufacturing is an exhaustive process, from quarry to lorry, and requires a high number of equipment to be controlled and signals to be monitored.
Designed specifically for the cement and mining industries, CEMAT library efficiently operates processes with a large number of interlocks and equipment, keeping the equipment safe.
Customers are looking for efficient resource utilisation, without compromising the quality and performance KPIs. Here is where CEMAT an integrated process control system with cement and mining standards comes into view. CEMAT is not just about delivering some operation blocks but setting up plant operation culture in the right perspective, backed by 50+ years of experience and knowledge embedded in its DNA.
Due to the legacy of CEMAT (900 installations worldwide), many cement manufacturers already speak the CEMAT language, making it easier for new customers to adapt to it quickly. Offering excellent process automation and a solid base for digitalisation, it plays a key role in all phases of cement production.

What energy efficiency gains can clients expect from your motor and drive solutions?
Our low voltage motors portfolio, based on global platform design, offers different efficiency class motors from IE2 to IE4. With every upgrade of efficiency class motors, clients can reduce losses by 20 per cent thereby reducing energy consumption and carbon emissions.
The Totally Enclosed Fan-Cooled (TEFC) motors with medium and high voltage motors (IE3 / IE4) are sealed and use external fans for cooling, which reduces energy losses due to friction and prevents dust and moisture from degrading performance over time. TEFC high-efficiency motors maintain good efficiency even when not operating at full load, which is common in cement processing where demand fluctuates. These motors run cooler, reducing energy wasted as heat and enhancing reliability—ideal for harsh environments like kilns, crushers and conveyors. Greater efficiency means less energy consumed, directly lowering the carbon footprint of the cement production process.
In one of the cement plants, the 40-year-old Direct Current (DC) motor for process fans was converted to high voltage induction motor along with our GH180 medium-voltage drives. Equipped with the latest generation and advanced cell bypass, the client was able to achieve 50-80 per cent of energy savings benefits, i.e. 3000+ MW energy savings per year and 2500+ tonnes carbon reduction per year.

How does your AI driven AIKiln or AIMill optimise kiln and mill operations?
Our DigiMine AI Pyro and AI Mill solutions provide optimum setpoints for pyro and mill automation systems, ensuring efficient and stable operations and thereby enhancing productivity and energy optimisation.
These solutions are powered by self-learning AI technology, which can adapt its algorithms in case of changes in the process or operating environment.
AI Simulator, which is a part of the solution, further enables process teams to identify improvement areas and validate improvement steps virtually, saving time and material wastage in trying implementations of different steps at site.

Can you share a case where automation improved environmental performance in cement production?
Basic CEMAT library takes care of the basic plant operations. But when it comes to advanced control, we have the CEMAT Kiln Control System (KCS) / Mill Control System (MCS), which helps customers achieve their sustainability goals.
In one of our projects, CEMAT MCS for mill operation implemented to control the mill feed was able to save 12 per cent of power required for grinding equivalent amount of cement.

How do your scalable automation solutions support both new builds and plant revamps?
The PCS7 CEMAT based automation solutions are truly scalable. It supports multiple versions in a single project; this enables individual sections to upgrade while other sections are in operation.
In new builds, the scalable capability of CEMAT automation solutions supports simultaneous commissioning of various plant sections, which helps in reducing the overall commissioning time.
For plant revamps, CEMAT automation solutions support cement manufacturers in scaling the plant while many sections are still in operation. Hence, with reduced overall downtime, customers can easily plan plant expansions during revamps.

How open and interoperable are your systems with existing OT IT ecosystems?
In the cement industry, in addition to automation systems there are various crucial systems like laboratory, SAP and external packages. Therefore, communication with the external world is the backbone for the entire process. PCS7 CEMAT supports all major available communication protocols for seamless communications.

What challenges do operators face in adopting AI based control, and how do you address them?
Majorly, we have experienced three challenges operators face in adopting AI-based control.
1. Operators are already used to the UI of
existing automation systems like SCADA or DCS. And adding a new screen with different UI makes it difficult for operators to monitor / operate separate systems.
2. Initial hesitation towards AI systems operating applications with changing plant conditions
like material quality, machine failure and
cement quality variation, which requires operators to make changes in control parameters on a continuous basis.
3. Often operators are also concerned about achieving target KPIs like production, power consumption, quality using AI based control system.
Addressing these issues is crucial for the success of an AI-based control system in every plant.
Decades of our experience working with cement companies enabled us to address these challenges in intuitive ways.
1. Embedding critical functions of AI systems into existing automation systems like SCADA makes it easy for operators to manage both automation and AI systems from a single screen.
2. Involving process team in solution development process, providing transparency on AI
systems working.
3. Training operators and providing detailed manuals on using AI systems along with basic know-how of AI technology encourages them to embrace AI systems with a positive outlook.
4. Continuous long operating hours of AI
systems, keeping process stable and achieving
targets enhances the confidence level of
operators gradually.
5. Self-learning-based and data-centric working of AI systems adapts to changing plant conditions and provides set-points accordingly, thus keeping processes like pyro and mill stable in different conditions. This further allows operators to undertake more critical tasks like process improvement, planning, and other tasks.

What’s next for Innomotics in cement automation and your roadmap for India and globally?
The current advancement in electrical and automation technologies has enabled the system to achieve its peak performance for day-to-day activities far smoother than it was earlier. Also, Industry 4.0 has enabled automation systems to provide efficient and consistent data.
With this advancement, AI-based systems have started receiving continuous meaningful data to perform many activities, which has allowed AI / ML models to predict outcomes accurately, thereby helping customers achieve their sustainability goals.
Currently we are implementing specific processes: AI systems i.e. AI Pyro and AI Mill. With our futuristic goal to develop a single AI system for the entire cement manufacturing process, we are on path to develop a common platform, which can connect with different automation / third-party systems to collect data seamlessly, provide analytics dashboards and reports 24X7 as well as provide set-points for control parameters from quarry to lorry.

The Karnataka Electricity Regulatory Commission (KERC) has proposed a reduction in the tariff paid for surplus electricity that rooftop solar installations export to the grid, prompting concern among consumers, renewable energy advocates and industry specialists. The proposal arrives while the Central government and state governments are promoting clean energy adoption and offering subsidy schemes to encourage rooftop solar deployment. Thousands of households in Karnataka, particularly in Bengaluru, have invested substantial sums in rooftop systems to reduce reliance on conventional power and support state renewable targets.

Stakeholders have raised questions about the implications of a lower export tariff for the financial attractiveness of rooftop solar investments and the pace of the state transition to renewables. Industry analysts warned that a reduction in compensation for excess generation could discourage new installations and extend payback periods for existing systems. Current messaging from authorities, which simultaneously promotes adoption while proposing lower export rates, has been described by user groups as creating contradictory signals for consumers.

Experts argued that policy measures should focus on grid modernisation rather than reducing consumer benefits, with investments in transmission and distribution networks needed to manage higher volumes of distributed solar generation. Consumer groups and renewable advocates are preparing written submissions to the regulator and are urging retention of incentives that support household adoption of rooftop systems. KERC has invited public objections and suggestions as part of a consultation process that will determine the final tariff framework.

The outcome of the consultation is expected to influence the future growth of rooftop solar across the state and shape investor confidence in small-scale renewable projects. Residents who have already installed rooftop panels are monitoring developments closely because changes to compensation mechanisms may affect household finances and the speed of return on investment. Observers noted that coherent policy, aligned incentives and grid upgrades would be essential to sustain momentum in the rooftop solar sector.

Specialised rail logistics will move fly ash from power plants to infrastructure industries.

New Delhi

Indian Railways is planning a large-scale green logistics initiative to transport fly ash from thermal power plants to industries where it can be reused in infrastructure and construction activities.

The initiative was discussed during a review meeting chaired by Union Minister for Railways Ashwini Vaishnaw. Union Ministers of State for Railways V Somanna and Ravneet Singh Bittu were also present.

India generates nearly 340 million tonnes of fly ash every year from thermal power plants. The proposed initiative aims to create an efficient rail-based transport system using specialised containers and dedicated logistics arrangements to move fly ash safely from power plants to end-use industries.

Fly ash is widely used in road construction, cement manufacturing, brick production, concrete, blocks and boards. By improving its movement through the railway network, the initiative is expected to support better utilisation of this industrial by-product while reducing environmental concerns linked to storage and disposal.

The move also aligns with India’s circular economy goals by converting waste from thermal power generation into a useful raw material for the construction and infrastructure sectors. Wider availability of fly ash can help reduce material costs in areas such as bricks and cement, supporting more affordable infrastructure and housing development.

Through this initiative, Indian Railways aims to provide a cleaner, safer and more organised transport solution for fly ash, turning an environmental challenge into an infrastructure resource.
