Waaree Transpower has committed a capital expenditure of ₹192 Crore (~₹1.92 Billion) to construct a dedicated manufacturing facility for extra-high voltage (EHV) 500 MVA, 400 kV class power transformers, with commercial commissioning targeted for April 2027. Ahead of the plant’s operational rollout, the company has secured a forward order backlog valued at approximately ₹360 Crore for FY 2026-27. The investment positions the enterprise to supply high-capacity grid step-up equipment and auto-transformers for India’s expanding bulk transmission corridors.
Investment Overview and Facility Specifications
Summary of Investment & Manufacturing Parameters
| Parameter | Details |
| Target Entity | Waaree Transpower |
| Capital Expenditure (CapEx) | ₹192 Crore (~₹1.92 Billion) |

The capital deployment establishes localized production capability for 400 kV class EHV equipment, strengthening domestic supply readiness for primary power grid interconnections ahead of the April 2027 operational deadline. Commercial execution is underpinned by pre-secured forward orders that provide revenue visibility as manufacturing lines and high-voltage testing bay capabilities are commissioned.
Corporate Evolution: Background on Waaree Transpower
- Acquisition and Rebranding History: Waaree Transpower formerly operated under the name Kotsons Private Limited until October, when it was acquired by Waaree Energies for ₹192 crore and subsequently rebranded to serve as the group’s power transmission manufacturing arm.
- Rapid IDT Commercial Rollout: Within one month of launching its inverter duty transformer (IDT) line, the entity secured a landmark ₹100 crore contract from a leading national solar EPC company to supply 1.27 GW of IDTs for utility-scale solar generation plants across multiple states.
- Technical Functional Distinction: Inverter duty transformers are specifically engineered to process high-voltage step-up operations and manage non-linear harmonic loads from solar power inverters, functionally differentiating them from conventional low-frequency AC distribution and sub-transmission transformers.
Sectoral Context and Market Landscape
Market Sizing & Growth
The expansion into 500 MVA transformer manufacturing coincides with strong growth across India’s power transmission infrastructure. Total domestic annual transformer sales are projected to surpass ₹40,000 crore in FY26. Market analysis projects the sector to grow from USD 3.25 billion in 2026 to USD 4.82 billion by 2031, reflecting a compound annual growth rate (CAGR) of 8.22%.
Large Transformer Segment
Large transformers rated above 100 MVA—the rating category that encompasses Waaree Transpower’s 500 MVA product line—represent the fastest-expanding tier in the domestic market. Driven by high-voltage grid interconnections and transmission corridor build-outs, this segment is forecast to grow at a 9.75% CAGR through 2031.
Grid & Infrastructure Drivers
- Transmission Corridor Expansion: The National Electricity Plan outlines the construction of 123,577 circuit km of new transmission lines between 2022 and 2027, creating baseline demand for EHV power and auto-transformers across interstate corridors.
- CEA Standardized Equipment Mandates: Guidelines enforced by the Central Electricity Authority (CEA) standardize technical specifications for substation equipment rated 66 kV and above, specifically establishing uniform design parameters for 765/400 kV networks and 500 MVA transformer configurations.
- Renewable Energy Integration Demands: India’s installed renewable energy generation capacity reached 226.79 GW as of June 2025. Interfacing utility-scale solar and wind parks with the central grid requires high-capacity step-up transformers at generation pooling stations.
- Global Supply Chain Constraints: International delivery lead times for large power transformers (345 kV to 765 kV) have extended to 104–156 weeks due to worldwide component shortages and capacity deficits, increasing reliance on domestic OEM supply chains.
