POWERGRID Tenders 6 GW Solar Evacuation Project in Rajasthan

Background and Context

The Power Grid Corporation of India (POWERGRID) has initiated a significant expansion of the national grid infrastructure to support the country’s ambitious renewable energy targets. By issuing two new tenders for ±800 kV high-voltage direct current (HVDC) transmission lines, the corporation aims to facilitate the evacuation of 6 GW of solar power originating from the Rajasthan Renewable Energy Zone Phase-IV. This development is a pivotal step in integrating massive solar clusters into the interstate transmission system (ISTS).

Key Details

The first tender focuses on a pre-bid tie-up for an HVDC bipole line connecting the Barmer-II terminal in Rajasthan to the South Kalamb terminal in Maharashtra. Bidders for this package must demonstrate a minimum average annual turnover of ₹2.54 billion and access to liquid assets of at least ₹424.7 million. The second tender covers the LILO of the 400 kV Fatehgarh-IV–Barmer-I line and additional HVDC bipole infrastructure. This package requires a minimum average annual turnover of ₹2.17 billion and liquid assets of ₹363.2 million. Both tenders mandate that the successful contractor must have completed at least 100 km of 345 kV D/C or higher voltage transmission lines within the last seven years. The projects have a strict completion timeline of 38 months, with a bid submission deadline of April 17, 2026.

What This Means for EPCs and Developers

For EPC contractors, these tenders represent a high-value opportunity to participate in complex HVDC infrastructure projects. The technical requirements emphasize experience in tower foundation, erection, and stringing at high-voltage levels. Developers operating in the Rajasthan REZ Phase-IV stand to benefit significantly, as these transmission lines are essential for the commercialization of their solar assets. The inclusion of relaxation clauses for startups and MSEs regarding turnover and liquidity thresholds provides a broader window for emerging players to enter the high-stakes transmission segment.

What Happens Next

The industry is now focused on the April 17, 2026, bid opening date. Following the selection of the successful bidders, the 38-month construction phase will commence, which will be closely monitored by stakeholders to ensure the timely evacuation of solar power. As India accelerates its renewable energy sector context, the successful execution of such large-scale transmission projects remains the backbone of the country’s transition to a sustainable, low-carbon energy grid.
