POWERGRID Floats Tender For 800 kV HVDC Line To Evacuate 6 GW Rajasthan Solar Power Project

Power Grid Corporation of India Limited (POWERGRID) has invited bids for a major transmission infrastructure project aimed at strengthening India’s renewable energy evacuation network. The tender, issued under reference number CC/T/W-TW/DOM/A04/26/04506, focuses on building a high-voltage transmission line that will play an important role in transferring solar power from western India to demand centers.

The project is part of the country’s broader plan to support large-scale renewable energy generation, especially from the Rajasthan Renewable Energy Zone (REZ). Under the scope of work, the selected contractor will develop an 800 kV HVDC bipole transmission line using advanced Hexa lapwing conductors. This line will connect the Barmer-II HVDC station to the South Kalamb HVDC station as part of the fifth phase of development.

This infrastructure is directly linked to the evacuation of power from the upcoming 6 GW Barmer Solar Complex, one of the largest solar energy developments in India. By enabling efficient transmission of clean energy, the project will help reduce dependency on fossil fuels and improve grid reliability. Although the tender is being managed from the POWERGRID office in Gurugram, Haryana, the actual construction work will mainly take place in Gujarat.

The project is being implemented through the Tariff-Based Competitive Bidding (TBCB) route, which ensures transparency and competitive pricing in the selection process. Interested companies are required to pay a non-refundable tender fee of ₹25,000 to participate. While the Earnest Money Deposit (EMD) is listed as zero in the summary, bidders are expected to submit a Bid Security Declaration or other financial guarantees as specified in the detailed tender documents available on the PRANIT portal.

In addition, the selected contractor will need to provide a Performance Bank Guarantee (PBG), which usually ranges between 3 percent and 10 percent of the total contract value. This is a standard requirement in central utility projects to ensure timely completion and quality of work.

The timeline for the bidding process is relatively short. The sale of tender documents started on April 6, 2026, and will close on April 14, 2026. Bid submission has also begun and will continue until April 16, 2026, at 11:00 AM. The technical bids will be opened on the same day at 11:30 AM.

All submissions must be made online through the PRANIT e-tendering portal. The process is being overseen by Vikash Chandra, Deputy General Manager at POWERGRID. This project is a key part of India’s Green Energy Corridor initiative, which aims to build strong transmission systems for renewable energy. Once completed, it will support the smooth flow of solar power from Rajasthan to other regions, helping the country move closer to its clean energy targets.
