On Monday, May 25, 2026, the Central Electricity Regulatory Commission (CERC) officially approved Tata Power’s tariff adoption and transmission license applications for the Eastern Region Expansion Scheme-XXXIX (ERES-XXXIX).
Executed through the special purpose vehicle TP Gopalpur Transmission Limited, this project represents a fundamental shift in how India builds infrastructure: laying high-voltage networks ahead of anticipated industrial demand to unlock massive clean energy manufacturing hubs.
Project Blueprint: The Gopalpur Grid Foundation
The project is explicitly engineered to handle high-load, power-intensive industrial processes.
- Core Infrastructure: Setting up a cutting-edge 765/400 kV Gas Insulated Substation (GIS) at Gopalpur, Odisha, along with extensive associated high-voltage transmission interconnects.
- Target Commissioning: December 2027.
- Fiscal Metrics: CERC adopted annual transmission charges of ₹2,897.29 million (~₹289.7 crore). Discovered via Tariff-Based Competitive Bidding (TBCB) under Section 63 of the Electricity Act, this aggressive rate landed 24.43% below initial regulatory cost estimates.
- Future-Proofing: The design leaves ample margin for growth, pre-building provisions for extra line bays, interconnecting transformers (ICTs), and scalable voltage systems.
The 90-Round Electronic Reverse Auction
Securing the project required a fierce corporate battle. Four of India’s largest infrastructure players advanced to the final financial bidding round:
- Tata Power (Winner)
- Power Grid Corporation of India (PGCIL) (Runner-up)
- Adani Energy Solutions
- Sterlite Grid 32
The bidding concluded after a grueling 90 rounds of electronic reverse auction, where Tata Power edged out the state-run PGCIL by a razor-thin margin—PGCIL’s final bid of ₹2,904.56 million was just 0.25% higher.
Strategic Context: Activating Odisha’s Green Corridor
The Gopalpur Special Economic Zone (SEZ) and its adjoining industrial parks are rapidly morphing into India’s eastern capital for green technology. Upstream solar manufacturing—specifically the production of ingots, wafers, and cells—is highly energy-intensive and requires absolute grid stability.
This 765 kV grid acts as the definitive catalyst for several mega-facilities coming up along the coastline:
| Developer | Planned Facility Capacity at Gopalpur |
| Saatvik Green Energy | Integrated cluster for 4.8 GW Solar Cells & 4 GW Solar Modules |
| World Green Energy | 2 GW TOPCon Solar Cells & 1.2 GW Solar Modules |
| Avaada Group | Large-scale Green Hydrogen & Green Ammonia export terminal |
| Ocior Energy | Deep-water green hydrogen production facility |
“The approval points to a broader shift in how transmission planning is being approached in India — with infrastructure increasingly being laid ahead of anticipated industrial demand rather than purely in response to existing load.”
