Power Grid Corporation of India (POWERGRID) has commissioned a transmission project serving the 2,500 MW Solar Energy Zone in Bidar, Karnataka. The project was developed under the Tariff-Based Competitive Bidding (TBCB) route and will support the evacuation of electricity generated in the zone.
Commissioning Timeline
The project achieved its Date of Commercial Operation (DOCO) on October 5, 2026. POWERGRID received the corresponding notification by email on October 8, 2026, confirming that the transmission asset had entered commercial service.
Corporate Structure Behind the Project
The project was originally assigned to POWERGRID Bidar Transmission, a wholly owned subsidiary of POWERGRID. That entity was later amalgamated with POWERGRID Khavda II-C Transmission, effective March 1, 2026. The merger followed an order dated January 27, 2026, issued by the Ministry of Corporate Affairs.
Part of a Wider Transmission Build-Out in Karnataka
The commissioning adds to the transmission infrastructure being developed across Karnataka for renewable power projects. Other recent developments include:
- Kshema Power: has secured an order to develop transmission infrastructure for a 315 MW wind power project.
- Jyoti Structures: has commissioned the 400 kV Gadag-II Transmission Line for ReNew Power. The line supports evacuation of renewable energy from the Koppal Solar Energy Zone, which has an estimated generation capacity of 1,500 MW, under the Build, Own, Operate and Maintain model.
- Bajel Projects: has secured the Bellary-Davanagere transmission line Package TL01 order. The package covers a second 400 kV quad double-circuit line, meant to integrate additional renewable energy potential of 0.25 GW at Davanagere and 2.75 GW at Bellary. The 70 km line will connect the Bellary Substation with the Davanagere Substation, forming a link for evacuating renewable power into the national grid.
Why It Matters?
Solar and wind zones deliver value only when the power they generate can reach consumers. Transmission is the link that makes that possible, which is why projects like this one matter alongside the generation capacity itself. With several lines now being built or commissioned across Karnataka, the state’s renewable zones are gaining the grid connections they need.
