Three new plants in Gujarat will focus on high-voltage transformer bushings, pressboard and insulation materials, and continuously transposed conductors. Here is what the investment means for India’s power equipment supply chain—and where manufacturers could find opportunities.
By MFG Magazine Editorial Team
India’s power infrastructure is entering a major expansion phase. Renewable energy projects, industrial electrification, data centres and rising electricity demand are increasing the need for a stronger transmission network. But expanding the grid requires more than power lines and substations. It also depends on the availability of specialised transformers and the critical components inside them.
Against this backdrop, Transformers and Rectifiers (India) Limited (TARIL) announced an investment of ₹1,250 crore to establish three greenfield manufacturing plants at its Chiyada manufacturing complex in Gujarat.
The facilities are planned to manufacture high-voltage transformer bushings, pressboard and insulation materials, and continuously transposed conductors (CTC). According to the company’s announcement, construction began in December 2025, with commercial operations expected to begin in the first quarter of FY2027–28.
The company projects more than 1,000 direct jobs and annual revenue potential of approximately ₹2,000 crore once the facilities are fully operational. These are company projections, not guaranteed outcomes.
For India’s manufacturing ecosystem, the announcement raises an important question: Can the expansion of specialised power equipment manufacturing create opportunities for a wider network of Indian suppliers, engineering companies and MSMEs?
The answer depends on the capabilities suppliers can offer, the qualification standards they can meet and how effectively they connect with the power equipment value chain.

The three facilities will operate under a wholly owned consolidated ancillary subsidiary of TARIL. The company says this structure will give it greater control over manufacturing quality, technology, procurement and long-term strategic direction.
The investment is also intended to strengthen backward integration: bringing more critical component manufacturing within the company’s own ecosystem rather than depending entirely on external suppliers.
2. Why India Needs More Transformer and Power Equipment Manufacturing
India’s electricity transition is creating a substantial infrastructure requirement. Renewable generation must be connected to demand centres, interstate transmission capacity must increase, and the grid must accommodate new loads from industrial facilities, electric mobility and data centres.
According to the Ministry of Power’s National Electricity Plan (Transmission), India’s transmission network is planned to expand from approximately 5.09 lakh circuit kilometres in June 2026 to 6.48 lakh circuit kilometres by 2032. Transformation capacity is planned to increase from approximately 1,478 GVA to 2,345 GVA over the same period.
The plan also envisages an increase in inter-regional transmission capacity from 120 GW in June 2026 to 168 GW by 2032.
These are planning targets, not completed infrastructure. Nevertheless, they indicate the scale of the grid expansion being prepared.
Why does this matter to manufacturers?
A larger and more complex transmission network requires power transformers, substations, switching equipment, insulation systems, conductors and associated engineering services. Transformers are particularly important because they enable electricity to be transferred between voltage levels across generation, transmission and distribution systems.
Manufacturing these assets depends on a network of specialised suppliers. A shortage or quality failure in a critical component can delay equipment production, testing and delivery.
For this reason, domestic availability of specialised components can be strategically valuable. Local manufacturing may improve supply-chain resilience, reduce certain import dependencies and support coordination between component makers and transformer manufacturers.
However, domestic production does not automatically eliminate imports. Cost, technical qualification, material availability, production yields and customer approvals will continue to influence sourcing decisions.
3. Understanding the Three Products TARIL Plans to Manufacture
The significance of the project becomes clearer when we examine the technical role of each product.
A. High-Voltage Transformer Bushings: Insulation at the Point of Connection
A transformer bushing allows an electrical conductor to pass safely through a grounded barrier, such as a transformer tank, while maintaining the required electrical insulation.
In high-voltage applications, the bushing must manage substantial electrical stress while withstanding thermal, mechanical and environmental conditions. Its performance is essential to the safe operation and reliability of the transformer.
TARIL says its new bushing facility will manufacture three types:
- OIP — Oil Impregnated Paper: Uses paper insulation impregnated with oil as part of the insulating system.
- RIP — Resin Impregnated Paper: Uses resin-impregnated paper to provide the required electrical insulation.
- RIF — Resin Impregnated Fibre: Uses resin-impregnated fibre-based insulation construction.
The planned range extends up to 800 kV, placing the facility in a technically demanding segment of the market.
What makes this important?
Manufacturing high-voltage bushings is not simply a machining exercise. It requires specialised materials, controlled production processes, electrical design expertise, careful assembly and rigorous testing.
Suppliers hoping to participate in this value chain may need to demonstrate material consistency, dimensional accuracy, process traceability and the ability to meet demanding quality requirements.
Potential adjacent capabilities include precision-machined parts, metal fittings, specialised tooling, process equipment, test fixtures and selected manufacturing services. These are potential supplier categories to investigate—not confirmed purchase orders from TARIL.
B. Pressboard and Insulation Materials: The Foundation of Transformer Reliability
Electrical insulation is a fundamental part of transformer design. It helps separate conductive components, manage electrical stress and support reliable operation under demanding conditions.
Pressboard and other insulation materials are used in transformer insulation systems, depending on the design and application.
Their performance can be affected by material purity, moisture content, thickness consistency, mechanical strength, processing and compatibility with the overall insulation system.
For manufacturers, this creates a specialised materials opportunity—but also a demanding qualification challenge.
Potential supporting activities include precision cutting, conversion and finishing, material handling, packaging, moisture-controlled storage, testing and industrial process equipment. The specific requirements depend on the product and the buyer’s approved specifications.
MSMEs should be careful not to assume that general-purpose paper, board or polymer products can substitute for transformer-grade insulation materials. High-voltage applications require materials designed and tested for the intended electrical and operating conditions.
C. Continuously Transposed Conductors: Improving Winding Performance
Continuously transposed conductors, commonly called CTC, are used in transformer windings, particularly in applications where electrical and thermal performance are important.
A CTC is formed from multiple individually insulated rectangular conductor strands arranged and transposed in a controlled pattern. This arrangement helps manage circulating-current losses and supports efficient winding design in suitable applications.
Manufacturing CTC requires control over conductor dimensions, insulation quality, transposition geometry, surface condition and consistency along the length of the product.
Potential supporting capabilities include copper processing, precision drawing and rolling, conductor insulation, specialised dies and tooling, production-line automation, inspection systems and quality measurement equipment.
However, CTC is not an ordinary copper-wire product. A supplier entering this segment must understand the electrical, mechanical and process requirements of transformer winding applications.
For Indian manufacturers, this illustrates a wider opportunity: moving beyond basic metal processing into engineered electrical materials and higher-value components.
4. Seven Supplier Opportunities Indian Manufacturers Should Investigate
TARIL’s investment is not evidence that the company is seeking new suppliers in every category below. The following opportunities are derived from the products being manufactured and the industrial processes typically required in specialised electrical equipment production.
Suppliers should validate demand, approved-vendor requirements and procurement routes directly with relevant manufacturers before making investment decisions.
Opportunity 1: Precision Engineering and Machined Components
High-voltage electrical equipment includes assemblies that require accurate dimensions, surface finish, repeatability and reliable material properties.
Potential areas for capable engineering companies to investigate include:
- Precision-machined metal parts and fittings
- Custom fixtures and tooling
- Components for production and assembly equipment
- Special-purpose machine parts
- Jigs, gauges and inspection fixtures
What suppliers need: Reliable CNC machining or equivalent processes, measurement capability, material traceability, documented inspection and consistent delivery.
The most promising route for smaller firms may be to supply approved components or manufacturing services to established equipment makers rather than immediately attempting to manufacture highly specialised finished electrical products.
Opportunity 2: Copper Processing and Conductor-Related Capabilities
Copper is an important material in transformer windings and electrical conductors. CTC manufacturing adds further requirements involving strand preparation, insulation and controlled transposition.
Potential supporting areas include copper processing, precision rolling, conductor handling equipment, specialised tooling and selected insulation-related services.
What suppliers need: Tight dimensional control, surface-quality management, material certification, process consistency and the ability to meet electrical-material specifications.
The opportunity is not limited to selling raw copper. Companies with the right technical capabilities may be able to participate further up the value chain.
Opportunity 3: Industrial Machinery, Automation and Production Equipment
Specialised components require controlled manufacturing environments and repeatable processes.
This can create demand for industrial equipment such as:
- Precision winding and conductor-processing machinery
- Automated handling systems
- Special-purpose production equipment
- Industrial control panels and electrical systems
- Sensors, monitoring systems and machine-safety solutions
- Inspection fixtures and process-control equipment
What suppliers need: Application engineering, dependable commissioning, technical documentation, maintenance support and the ability to integrate equipment into production lines.
For Indian automation and machinery manufacturers, specialised electrical equipment plants can be useful target segments. But the actual scope depends on the equipment TARIL chooses to procure and manufacture internally.
Opportunity 4: Testing, Measurement and Quality Systems
Quality assurance is central to high-voltage equipment. Product qualification and testing requirements vary by component, design and applicable standards.
Potential opportunities include test fixtures, dimensional inspection, calibration, selected electrical testing equipment, data acquisition, traceability systems and production-quality software.
What suppliers need: Demonstrable measurement accuracy, calibration records, competent technical support and an understanding of the applicable testing standards.
Testing services and equipment should be matched to the specific component and customer requirements. A general industrial testing capability does not automatically qualify a supplier for high-voltage applications.
Opportunity 5: Specialised Materials and Industrial Consumables
The manufacturing processes involved may require controlled-quality materials, packaging, process consumables and supporting products.
Potential areas to investigate include specialised insulation-related materials, approved metal inputs, protective packaging, moisture-control solutions and selected industrial consumables.
What suppliers need: Consistent specifications, batch traceability, appropriate material documentation and reliable supply.
This segment may be accessible to established material suppliers, but transformer-grade materials can have strict technical requirements. Suppliers should confirm specifications before investing in inventory or production capacity.
Opportunity 6: Fabrication, Plant Infrastructure and Industrial Services
New manufacturing facilities require plant infrastructure and supporting services, although the project’s procurement arrangements have not been publicly established in detail.
Potential areas could include industrial fabrication, equipment foundations, utility systems, material-handling infrastructure, electrical installation, maintenance and selected engineering services.
What suppliers need: Relevant project experience, safety compliance, qualified manpower, schedule discipline and appropriate statutory documentation.
Local engineering contractors may find opportunities if packages are outsourced. They should not assume that all construction or installation work remains available, particularly because TARIL says construction began in December 2025.
Opportunity 7: Digital Manufacturing and Process Traceability
Specialised production increasingly depends on reliable process data, inspection records, material traceability and equipment performance monitoring.
Potential solutions include manufacturing execution systems, shop-floor data collection, machine monitoring, digital quality records, maintenance systems and production dashboards.
What suppliers need: Industrial integration experience, data integrity, cybersecurity awareness, dependable implementation and the ability to work with the plant’s existing systems.
This opportunity is relevant to industrial software and automation companies. However, the project announcement does not confirm any specific digital technology procurement.
5. What This Could Mean for Indian MSMEs
The most useful question for an MSME is not simply, “How can we supply TARIL?” It is, “Which part of the power equipment value chain can we serve competitively, and what evidence can we provide that we are qualified to do so?”
There are several possible routes.
Route 1: Supply directly to the manufacturer. This may suit suppliers whose products match the manufacturer’s approved sourcing requirements and who can satisfy its commercial, technical and quality criteria.
Route 2: Work with established Tier-1 suppliers. Smaller manufacturers may find it easier to enter through an approved supplier already serving transformer or electrical equipment manufacturers.
Route 3: Supply equipment and services rather than finished components. Machinery, tooling, inspection fixtures, industrial automation and maintenance can offer entry points for firms that do not manufacture electrical insulation systems or high-voltage products themselves.
Route 4: Build a specialised capability before approaching buyers. A firm may need to improve its process control, metrology, material traceability, testing or documentation before it is ready to compete for demanding industrial work.
The correct route depends on the MSME’s existing capabilities, investment capacity and target product.
6. A Practical Qualification Checklist for Prospective Suppliers
Before approaching TARIL or other transformer manufacturers, suppliers should prepare a concise capability package.
Technical Readiness
- Clearly defined product or service scope
- Drawings, specifications and process capability
- Material grades and traceability arrangements
- Inspection and test plans
- Calibration records and measurement equipment details
- Documented corrective and preventive action procedures
Quality and Compliance
- Applicable quality-management certifications, where required
- Customer-specific qualification records
- Process documentation and inspection reports
- Traceability from incoming material to finished product
- Safety, environmental and statutory compliance appropriate to the work
ISO certification can support a supplier’s credibility, but it does not replace customer qualification or product-specific testing.
Commercial Readiness
- Realistic costing and a documented quotation process
- Production capacity and lead-time estimates
- Raw-material sourcing plan
- Working-capital requirements
- Contingency planning for supply disruptions
- After-sales, warranty or field-support arrangements where relevant
A Stronger First Approach
Rather than sending a generic company profile, suppliers should prepare a focused two-page capability note containing:
- The exact product or service offered.
- Relevant technical specifications and production capacity.
- Existing customers or comparable applications, where disclosure is permitted.
- Quality certifications and inspection capabilities.
- Typical lead times and the location of manufacturing.
- A technical contact who can respond to qualification questions.
The objective of the first contact should be to establish relevance and understand the supplier qualification process—not to assume that a purchase order is immediately available.
7. Why Qualification Matters More Than Price Alone
High-voltage power equipment is a reliability-critical segment. A component that fails to meet its specifications can cause rework, production delays or operational problems after installation.
For this reason, buyers typically evaluate more than the quoted price. Relevant considerations may include:
- Conformance to drawings and technical specifications
- Process repeatability and defect rates
- Material traceability and inspection documentation
- Delivery reliability
- Engineering support and responsiveness
- Total cost of ownership and supplier stability
A low-cost supplier that cannot demonstrate consistent quality may not be competitive in practice.
For MSMEs, investment in metrology, process discipline, technical training and documented quality systems can therefore be as important as investment in additional machines.
8. The Strategic Significance of Backward Integration
TARIL’s decision to develop these three facilities within a wholly owned ancillary subsidiary is an example of backward integration: bringing selected inputs or production stages under closer corporate control.
For the company, this may help improve coordination across production, quality, procurement and delivery. It may also give the business greater control over critical manufacturing processes.
For the wider supplier ecosystem, the effect is more nuanced.
Backward integration can reduce external demand for the specific components a company chooses to make internally. At the same time, a larger manufacturing operation may require additional machinery, tooling, maintenance, materials, logistics and engineering support.
Consequently, the net opportunity for outside suppliers will depend on the scope of internal production, the supplier categories TARIL chooses to outsource and the future volume of its business.
MSMEs should therefore target genuine capability gaps—not assume that every component used by the new plants will be externally procured.
9. What Suppliers Should Watch Over the Next 12–18 Months
The period leading up to the expected commercial start of operations could provide useful signals for businesses tracking the project.
Manufacturers and service providers should monitor:
Vendor registration and qualification: Whether TARIL or its relevant procurement partners publish supplier-enrolment requirements or invite capability submissions.
Equipment and infrastructure packages: Any public tenders, contract awards or credible announcements relating to plant equipment, utilities, testing systems and installation.
Technical requirements: Specifications, certification expectations and qualification procedures for the relevant component categories.
Commissioning milestones: Updates on installation, trial production and commercial readiness.
Actual procurement opportunities: Confirmed requests for quotations, tenders or vendor enquiries, rather than general claims that a new investment automatically creates supplier contracts.
These checks will help businesses separate a potential market opportunity from a verified sales lead.
10. The Bigger Picture: Building a Stronger Domestic Power Equipment Ecosystem
TARIL’s ₹1,250 crore expansion is taking place against a long-term national plan to strengthen India’s electricity transmission infrastructure.
The Ministry of Power’s roadmap envisages significant growth in transmission lines and transformation capacity through 2032. Achieving those plans will require not only generation capacity, but also equipment manufacturing, engineering expertise, quality systems, skilled workers and resilient supply chains.
The strategic challenge is to build domestic capabilities that meet technical requirements at competitive costs and at the scale required by infrastructure projects.
For Indian MSMEs, this does not mean every company should enter high-voltage component manufacturing. The capital, expertise and qualification requirements can be substantial.
A more practical strategy is to identify a specific part of the value chain where the company has a credible advantage—whether in precision engineering, copper processing, industrial automation, testing, materials, fabrication or maintenance—and build the capabilities required to serve that segment.
The companies most likely to benefit will be those that connect their investment decisions to real customer requirements rather than relying on broad market optimism.
Conclusion: A Manufacturing Opportunity, but Not an Automatic Order Pipeline
TARIL’s planned investment in three manufacturing plants at Chiyada represents a significant move towards localising selected critical transformer components. Its focus on bushings up to 800 kV, pressboard and insulation materials, and continuously transposed conductors reflects the technical depth required to manufacture high-voltage power equipment.
The project also highlights a wider opportunity for India’s industrial ecosystem: developing specialised materials, engineering, automation and quality capabilities that support the country’s expanding power infrastructure.
For MSMEs, the message is straightforward. Identify the product or service you can deliver reliably, understand the buyer’s qualification standards, document your capabilities and pursue the appropriate procurement route.
The investment may create opportunities across the supply chain, but those opportunities will need to be verified and won through technical competence, quality, cost and delivery performance.
India’s power infrastructure ambitions will depend not only on building more equipment, but also on building a dependable manufacturing ecosystem around it.
