Power Grid Corporation of India has announced a major infrastructure investment following board approval for the upgrade of its Bhadrawati HVDC back-to-back system. The board of directors accorded the investment approval for ₹1,226.93 crore in their meeting, as disclosed under Regulation 30 of SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

Investment Details

The board has sanctioned a substantial investment for this critical infrastructure project:

Project Scope and Significance

The project involves the refurbishment of Bhadrawati (Chandarpur) HVDC (2X500MW) back-to-back system under the Additional Capital Expenditure 2024-29 Tariff Block. HVDC (High Voltage Direct Current) back-to-back systems play a crucial role in power transmission infrastructure by enabling efficient power transfer between different AC networks while maintaining system stability.

The 36-month implementation schedule from the date of award indicates a comprehensive upgrade project that will likely involve advanced technology implementation and substantial infrastructure development. This timeframe suggests careful planning to ensure minimal disruption to existing operations while implementing state-of-the-art transmission capabilities.

Strategic Infrastructure Investment

This ₹1,226.93 crore investment underscores Power Grid Corporation's ongoing commitment to strengthening India's power transmission backbone. The upgrade of the Bhadrawati facility aligns with the company's broader strategy of modernizing transmission infrastructure to meet growing power demand and enhance grid reliability.

The substantial capital allocation reflects the technical complexity and strategic importance of HVDC systems in maintaining efficient power flow across the national grid. Such investments are essential for supporting India's growing energy requirements and ensuring stable power supply across different regions.

Power Grid Corporation of India has been declared the successful bidder under Tariff Based Competitive Bidding (TBCB) for establishing Inter-State Transmission System for the Inter-Regional Strengthening project between Southern Region (SR) Grid and Eastern Region (ER) Grid. The company received the Letter of Intent (LoI) for the project, which involves 765kV transmission lines on a Build, Own, Operate and Transfer (BOOT) basis.

Project Specifications

The project will be executed on a BOOT basis, demonstrating Power Grid Corporation of India's comprehensive involvement in the transmission infrastructure lifecycle. The technical specifications and geographical scope highlight the project's strategic importance:

Infrastructure Components

The project comprises 765kV Double Circuit (D/C) transmission lines that will traverse through the states of Odisha and Andhra Pradesh. The infrastructure development includes associated line bays and reactor works at both ends, ensuring comprehensive grid connectivity and stability between the two regional grids.

Strategic Grid Enhancement

This Inter-Regional Strengthening initiative represents a critical infrastructure development that will significantly improve power transfer capabilities between India's Southern and Eastern regions. The 765kV transmission system will enhance grid reliability and enable efficient power flow management across regional boundaries.

The successful bid acquisition reinforces Power Grid Corporation of India's position as India's leading transmission utility and demonstrates the company's continued involvement in critical national infrastructure projects. This project will contribute to the overall robustness of India's power transmission network, supporting the country's growing energy demands and ensuring reliable electricity supply across different states and regions.
