New Delhi: Power Grid Corporation of India Limited has been declared the successful bidder for the WR–ER Inter-Regional Network Expansion Scheme Part-A under the Tariff Based Competitive Bidding (TBCB) mechanism.
The company received the Letter of Intent (LoI) on June 16, 2026, marking a significant step in strengthening India’s national electricity transmission infrastructure.
The project will be developed on a Build, Own, Operate and Transfer (BOOT) model, ensuring long-term operation before transfer to the government.
Project Aims: Strengthening India’s Inter-Regional Power Flow
The transmission project is designed to enhance electricity transfer capacity between India’s Western and Eastern regions, improving grid reliability and energy security.
Key objectives include:
- Strengthening inter-regional power transmission
- Improving grid stability and redundancy
- Supporting rising electricity demand across states
- Enabling smoother evacuation of power from generation-rich zones
Infrastructure Development Across Four States
The project covers multiple states, including Jharkhand, Chhattisgarh, Odisha, and West Bengal, and involves major upgrades to the national transmission network.
Key Components of the Project:
- Construction of two new 765/400 kV substations in Jharkhand and Chhattisgarh
- Extension of existing substations in Chhattisgarh and West Bengal
- Development of 765 kV and 400 kV transmission lines
- Strengthening inter-state grid connectivity across eastern and central India
These upgrades are expected to significantly improve power flow efficiency across the region.
Strategic Importance for India’s Power Sector
The WR–ER transmission corridor is a critical part of India’s national grid modernization strategy. The project is expected to:
- Enhance transmission capacity between key regions
- Improve integration of renewable energy sources in the future
- Strengthen national energy security
- Reduce transmission bottlenecks in high-demand corridors
It also supports India’s broader goal of building a more resilient and flexible power grid system.
BOOT Model to Drive Long-Term Infrastructure Efficiency
The project will be implemented under the BOOT (Build, Own, Operate and Transfer) framework, allowing Power Grid to develop and operate the assets for a defined period before transferring them to the government.
This model is widely used in large-scale transmission projects to ensure efficiency, private-sector participation, and faster execution.
