POWERGRID Tenders 6 GW Solar Evacuation System in Rajasthan

Background and Context

The Power Grid Corporation of India (POWERGRID) has officially invited bids to develop a robust transmission system designed to evacuate 6 GW of solar power from the Rajasthan Renewable Energy Zone (REZ) Phase IV. This initiative, specifically targeting the Barmer Complex (Barmer II), is a strategic move to integrate large-scale renewable energy into the national grid. As Rajasthan continues to emerge as a solar powerhouse, the development of reliable evacuation infrastructure becomes paramount to prevent curtailment and ensure efficient power distribution across the country.

Key Details

The scope of work involves the construction of a ±800 kV HVDC Bipole line (Hexa lapwing) connecting the Barmer-II HVDC terminal in Rajasthan to the South Kalamb HVDC terminal in Maharashtra, including a parallel dedicated metallic return. Prospective bidders must meet stringent technical and financial criteria. Technically, bidders must have completed at least one 345kV D/C or higher-voltage-class transmission line project of at least 100 km within the last seven years. Financially, the bidder must maintain a positive net worth over the last three financial years. Furthermore, the minimum average annual turnover for the best three of the last five years is set at ₹2.17 billion (~$23.47 million). Bidders are also required to demonstrate liquid assets or credit facilities of at least ₹362.4 million (~$3.92 million).

What This Means for EPCs and Developers

For EPC contractors, this tender represents a high-value opportunity to participate in one of India’s most significant HVDC transmission projects. The scale of the 6 GW evacuation requirement necessitates advanced technical expertise in high-voltage infrastructure. Developers focusing on the Rajasthan solar belt should note that this transmission link is essential for the long-term viability of their projects in the Barmer region. The project underscores the government’s commitment to strengthening inter-state transmission systems (ISTS) to handle the massive influx of renewable energy.

What Happens Next

The deadline for bid submission is April 20, 2026, with the bid opening process occurring on the same date. Interested parties must ensure all documentation aligns with the specified turnover and technical experience requirements. As India accelerates its transition toward a sustainable energy future, such transmission projects are vital to maintaining grid stability and meeting the ambitious renewable energy targets set by the Ministry of New and Renewable Energy (MNRE). The continued expansion of the Rajasthan REZ remains a cornerstone of the India renewable energy sector context, requiring constant investment in grid infrastructure.
