Power Transmission EPC Is Forecast to Outgrow Distribution by 2030

Power Transmission EPC is forecast to become the larger Indian power engineering, procurement and construction market by 2030, reaching Rs 99,545 crore against Rs 97,137 crore for distribution. The transmission EPC market is projected to grow at an 11.58% compound annual growth rate from 2024 to 2030, compared with 6.39% for distribution.

Why is transmission EPC projected to outgrow distribution by 2030?

Transmission EPC is projected to outgrow distribution because its market share is forecast to rise from 43.51% in 2024 to 50.61% in 2030, while distribution's share falls from 56.49% to 49.39%. Engineering, procurement and construction, or EPC, covers the design, equipment purchase and construction work needed to complete power infrastructure. The forecast places the combined transmission and distribution EPC market at Rs 1,96,682 crore in 2030, up from Rs 1,18,556 crore in 2024.

The difference marks a change from the market's earlier structure. In 2019, transmission accounted for 40.53% of the market and distribution held 59.47%. By 2030, the forecast reverses that relationship by 1.22 percentage points in favour of transmission. Transmission EPC is expected to add Rs 47,960 crore between 2024 and 2030, rising from Rs 51,585 crore, while distribution EPC is expected to add Rs 30,167 crore from Rs 66,970 crore.

The transmission forecast also implies a recovery and expansion from the 2020 low point of Rs 31,021 crore. The detailed outlook rises through Rs 57,923 crore in 2025, Rs 72,131 crore in 2027 and Rs 89,998 crore in 2029 before reaching Rs 99,545 crore in 2030. That path must hold for the 11.58% annual growth forecast to be achieved.

What is driving transmission EPC growth?

Transmission EPC growth is tied to planned high-voltage grid expansion needed to move power across regions and connect renewable generation. India’s transmission network had about 4,81,326 circuit kilometres of lines and 12,25,260 megavolt-amperes of transformation capacity as of January 31, 2024. Circuit kilometres measure the length of each electrical circuit, while transformation capacity measures the system’s ability to transfer electricity through substations.

The National Electricity Plan for transmission covers 2022-23 to 2031-32 and envisions 1,91,474 circuit kilometres of new lines at 220 kilovolts and above, plus 1,274 gigavolt-amperes of transmission capacity. It also includes 33.25 gigawatts of high-voltage direct current, or HVDC, bi-pole links. HVDC is used for long-distance transmission and is described as reducing losses relative to conventional alternatives.

The disclosed public plan is large in monetary terms: a Union Minister announced planned transmission expenditure of Rs 9.12 lakh crore by 2032 in November 2024. Inter-regional transfer capacity is planned to increase from 119 gigawatts to 143 gigawatts by 2026-27 and 168 gigawatts by 2031-32. Transmission EPC demand therefore depends on project execution under that plan, including lines, substations, HVDC links and grid technologies.

Renewable integration is another stated mechanism. India targets 500 gigawatts of renewable generation capacity by 2030, while major wind and solar capacity is concentrated in Rajasthan, Gujarat and Tamil Nadu. Connecting geographically concentrated renewable projects to the synchronised national grid requires high- and ultra-high-voltage infrastructure, including networks operating between 132 kilovolts and 765 kilovolts alternating current and at ±800 kilovolts HVDC.

How does the distribution EPC outlook differ?

Distribution EPC remains a growing market, but its projected 6.39% annual growth rate is below transmission EPC’s 11.58% rate. Its forecast value rises from Rs 66,970 crore in 2024 to Rs 97,137 crore in 2030. That is a Rs 30,167 crore increase, but less than the projected Rs 47,960 crore increase for transmission EPC over the same six-year period.

Distribution investment is being shaped by the Revamped Distribution Sector Scheme, or RDSS, which runs from FY 2021-22 to FY 2025-26. The scheme has an outlay of Rs 3.03 lakh crore and aims to modernise networks through prepaid smart metering, system metering and distribution infrastructure. Financial assistance is conditional on distribution companies, or DISCOMs, meeting pre-qualifying criteria and reform milestones.

The policy case is linked to aggregate technical and commercial, or AT&C, losses, which capture physical network losses and commercial losses such as inadequate metering and theft. DISCOM AT&C losses declined from 22.32% in FY 2021 to 16.44% in FY 2022, while the gap between average cost of supply and average revenue realised fell from Rs 6.90 per kilowatt-hour to Rs 0.15 per kilowatt-hour. RDSS targets nationwide AT&C losses of 12% to 15% and elimination of that cost-revenue gap by FY 2024-25.

Specific distribution programmes show the scale of work but also its different focus. In August 2024, the Ministry of Power approved Rs 3,600 crore for Gurugram and Faridabad upgrades, including 20 gas-insulated substations, 3,500 kilometres of underground cable and 5,000 new distribution transformers or compact substations. Such projects centre on local reliability, metering and last-mile systems rather than the inter-regional capacity additions that support the transmission forecast.

What could affect the projected transmission EPC expansion?

Transmission EPC expansion depends on timely execution despite cost, approval and delivery constraints identified for the wider EPC sector. Equipment normally represents 50% to 60% of total transmission and distribution infrastructure cost, while design and engineering account for 5% to 10%, civil construction 15% to 20%, and land, approvals, administration and other costs another 15% to 20%. Equipment availability, land acquisition, topography and prevailing market conditions can therefore affect project cost and timing.

The sector faces land-acquisition, environmental-clearance, regulatory-compliance, skilled-workforce and supply-chain constraints. High-voltage projects require specialised equipment including towers, transformers, switchgear and transmission lines. Delays in procurement, changes in design or policy, and payment delays can create cost overruns or working-capital pressure, particularly because EPC contracts may run for years.

Financial conditions in distribution also matter to contractors that work across the power network. As of March 31, 2023, DISCOM borrowings in the South were Rs 2,96,184 crore, compared with Rs 2,00,909 crore in the North. Financially strained state-run DISCOMs can delay payments to EPC contractors; this is a separate execution risk from the transmission investment plan, but it affects the broader power EPC operating environment.

Conclusion

India’s power EPC market is forecast to shift from distribution-led scale to transmission-led scale by 2030. Transmission EPC is projected to reach Rs 99,545 crore, exceed distribution’s Rs 97,137 crore and represent 50.61% of the market, reflecting planned high-voltage additions, inter-regional links and renewable-energy integration.

The next measure to watch is delivery against the National Electricity Plan through 2031-32: 1,91,474 circuit kilometres of planned lines, 1,274 gigavolt-amperes of planned capacity and inter-regional capacity of 168 gigawatts. The forecast also depends on the stated Rs 9.12 lakh crore transmission expenditure plan by 2032 proceeding alongside approvals, equipment procurement and contractor execution.
