A very healthy growth of over 35 per cent is expected in transmission infrastructure addition during the current fiscal year FY27. The 765kV voltage class is expected to have a much higher share than 400kV and 220kV.
Fiscal year FY26, which ended on March 31, 2026, proved very eventful for the ISTS-TBCB landscape with as many as 17 such schemes achieving full commissioning.
Power Grid Corporation of India Ltd (PGCIL) has been a very big contributor to all-India new transformation capacity addition during FY26, government statistics suggest.
Over 6,000 ckm of new transmission lines (of 220kV or above) were added on the interstate transmission system (ISTS) network during FY26 with contribution from tariff-based competitive bidding (TBCB) projects clearly dominating.
An exclusive study by tndindia.com suggests that 16 interstate transmission system schemes were awarded under the tariff-based competitive bidding mechanism in FY26. This ISTS-TBCB market was led by Adani Energy Solutions Ltd in terms of tariff-based share while PGCIL held leadership position with respect to number of schemes won.
The first quarter (Q1: April to June) of FY27 is expected to see significant addition of transmission infrastructure through interstate transmission system (ISTS) schemes awarded under the tariff-based competitive bidding (TBCB) mechanism.
Very recently, the Union ministry of new & renewable energy (MNRE) expanded the Approved List of Models & Manufacturers (ALMM) framework to cover solar ingots and wafers. This is aimed at further bolstering India’s self-sufficiency over the entire solar equipment value chain. Through earlier ALMM interventions, MNRE sought to reduce India’s import dependency on solar modules and cells. In this special study, tndindia.com tries to gauge the impact that the ALMM framework has had on increasing India’s self-sufficiency in the solar photovoltaic (PV) manufacturing ecosystem.
Power Grid Corporation of India Ltd (PGCIL) expects that it will have a project pipeline of around Rs.60,000 crore per year over the next decade.
In a newly-released report, Central Electricity Authority (CEA) has estimated that an investment of nearly Rs.8 trillion will be required during the ten-year period from FY27 to FY36, for evacuation of 900 GW of non-fossil power generation capacity.
The National Committee on Transmission (NCT) has proposed extension in implementation timeframe for ISTS schemes involving RE evacuation, which are currently under bidding.
