A joint venture between Hitachi Energy India Ltd and Bharat Heavy Electricals Ltd (BHEL) has been awarded a significant contract by Adani Energy Solutions Ltd (AESL) to develop the Rajasthan HVDC transmission project. In separate filings made on February 9, 2025, both companies announced that the consortium had received a letter of intent from Rajasthan Part I Power Transmission Ltd for the design and implementation of an HVDC link, along with associated AC substations. This project will facilitate the transmission of renewable energy from Bhadla III in Rajasthan to Fatehpur in Uttar Pradesh. Rajasthan Part I Power Transmission Ltd is a wholly-owned subsidiary of AESL.
While the formal contract agreement is yet to be finalized, the project is slated for completion by 2030. The value of the contract has not been disclosed. The project includes the installation of two HVDC LCC terminals, each with a capacity of ±800kV, 6,000 MW, located at Bhadla III and Fatehpur. It will also involve the HVDC transmission line and related AC substations.
AESL acquired Rajasthan Part I Power Transmission Ltd via a tariff-based competitive bidding (TBCB) route, marking this as the first HVDC project awarded to a private sector entity under the TBCB framework.
In November 2024, the same consortium of Hitachi Energy India and BHEL was awarded a similar project by Power Grid Corporation of India Ltd (PGCIL) for the HVDC system under “Khavda V-A Power Transmission Ltd,” a TBCB subsidiary of PGCIL. This project involves the installation of a ±800kV, 6,000 MW bi-pole, bi-directional HVDC link over 1,200 kilometers, connecting Khavda Pooling Station-2 (KPS2) in Gujarat to Nagpur in Maharashtra.
Both the Rajasthan and Khavda HVDC projects will utilize LCC (line commutable converter) technology, which was previously deployed in PGCIL’s ±800kV Raigarh-Pugalur HVDC link, stretching from Chhattisgarh to Tamil Nadu. This technology was also implemented by the Hitachi Energy India-BHEL consortium. However, the section of the Raigarh-Pugalur link from Pugalur to Thrissur uses a ±320kV HVDC system based on VSC (voltage source converter) technology, designed and commissioned by Siemens Energy and Sumitomo.
