India's Transmission Sector Eyes FY27 Rebound Amid Challenges

India's power transmission sector is set for a turnaround in FY27, following five years of slow growth. This recovery is expected to be driven by a significant ₹7.6 trillion investment opportunity over the next six years. The growth is fueled by the country's ambitious plans to integrate renewable energy and by changing government policies. However, the path to this recovery is challenging, and the sector's full potential depends on overcoming deep-rooted structural and regulatory issues. How policies are adjusted and projects are executed on the ground will determine if this revival leads to lasting growth or just a brief pause in ongoing problems.

Recovery Faces Hurdles Despite Project Additions

Signs of renewed activity appeared in FY26, with transmission line additions jumping 37% year-on-year and substation upgrades nearing goals. However, this progress comes as targets for the National Electricity Plan (NEP) by March 2027 are still likely to be missed. Long-standing issues like delays in acquiring land rights, complicated land valuation, the impact of a ruling on Great Indian Bustards (GIB), and equipment shortages due to limited imports from China have historically hindered project execution. Although the NEP plans for major transmission capacity increases, with an investment pipeline of around ₹9 lakh crore through 2032, past execution lags suggest that significant capital spending may be delayed beyond original timelines. The overall investment opportunity, estimated between ₹7.6 trillion and ₹9.16 trillion, depends on overcoming these persistent operational obstacles.

New Regulations Shift Project Economics and Strategy

Recent regulatory changes are set to slow the sector's growth. A key development is the phasing out of fee waivers for Inter-State Transmission System (ISTS) charges on renewable energy projects. This policy change is expected to impact project costs, potentially reducing the incentive to transmit renewable power over long distances. As a result, states might find it more cost-effective to develop local renewable sources, which could increase the need for intra-state transmission (InSTS) lines. While this could lead to more efficient capital use in the long run, it may benefit states with abundant renewable resources more than others. Energy storage systems, such as battery systems, are becoming essential for managing power flow, reducing the need for large transmission lines during peak times, and making better use of existing assets. The Central Electricity Authority is also pushing for green switchgear to decarbonize the grid, with new technical standards due in April 2027.

Asset Sales and Investment Trusts to Fund Growth

Meeting the sector's large capital needs will heavily rely on selling existing assets. The National Monetisation Pipeline (NMP) 2.0 aims to raise ₹2.3 trillion from transmission assets between FY26 and FY30, primarily through Build-Own-Operate-Transfer (BOOT) models and by securitizing assets of the Power Grid Corporation of India Limited (PGCIL). Infrastructure Investment Trusts (InvITs), like PGInvIT and IndiGrid, are expected to become more crucial. They attract institutional investors by offering stable returns from transmission assets with long operating lives. Despite challenges such as a shortage of available assets and limits on borrowing, work is being done to include related asset types and develop a list of priority assets. Selling state transmission assets, which make up nearly 90% of intra-state lines and represent a ₹2.9 trillion opportunity, is seen as the next major step. However, this requires states to ensure stable tariffs and speed up the transfer of assets.

Execution Delays and Competition Create Pressure

Even with talk of recovery, major challenges remain. The transmission sector's expansion has consistently fallen behind the growth of renewable energy, resulting in over 50 GW of renewable capacity being stranded as of June 2025 because of transmission limitations. Companies have also speculatively reserved transmission capacity in busy corridors, increasing costs and delaying necessary projects. Although Power Grid Corporation of India (POWERGRID) dominates inter-state transmission with about 85% of capacity, competition is growing. Private companies like Adani Energy Solutions and Sterlite Power are actively participating in Tariff-Based Competitive Bidding (TBCB) auctions. This focus on price, while good for lowering tariffs, squeezes profit margins and makes strong execution capabilities crucial. Additionally, the supply chain for transformers is strained, with manufacturing capacity struggling to meet demand. This leads to longer delivery times and potentially delays projects. The persistent difficulty in resolving land rights issues and obtaining permits remains a significant risk to completing projects on time and achieving expected returns.

Outlook: Integration and Storage Key to Future Growth

The National Electricity Plan forecasts significant expansion, aiming to integrate over 600 GW of renewable energy capacity by 2032. This will require a substantial rise in new transmission lines, with the pace needing to more than triple current levels to meet these targets. The ongoing integration of renewables, combined with electricity demand expected to grow by 6-6.5% annually, will continue to drive investment. Energy storage systems are viewed as vital for grid stability, managing supply and demand, and maximizing the use of assets. The sector's success in attracting the estimated ₹9 trillion to ₹9.16 trillion in capital spending through 2032 depends on effectively resolving execution, regulatory, and financing issues, while also adopting new technologies and pursuing strategic asset sales.
