More evacuation infrastructure planned for Kurnool RE zone in AP

A new interstate transmission system (ISTS) is being developed to evacuate renewable energy from the Kurnool Renewable Energy Zone (REZ) in Andhra Pradesh. The project, named “Transmission system for integration of Kurnool-IV REZ – Phase-I (for 4.5 GW),” will be implemented under the tariff-based competitive bidding (TBCB) route, with REC Power Development & Consultancy Ltd (RECPDCL) managing the process.

With an estimated cost of Rs 5.55 billion, the project is expected to be completed within 24 months from the SPV transfer date.

The key component is the Kurnool-IV Pooling Station (PS) with a capacity of 4×1500 MVA, 765/400kV, and 4×500 MVA, 400/220kV. The existing 765/400kV Chilakaluripet substation will also be upgraded. The Kurnool-IV PS will be connected to other substations like Kurnool-III PS, Bidar, and Chilakaluripet via 1,000 ckm of transmission lines.

This project is part of Andhra Pradesh’s plan to integrate 51 GW of renewable energy into the grid, with 23 GW identified for Kurnool (15 GW solar and 8 GW wind). Due to capacity limitations at the Kurnool-III PS, the new system is essential.
