Sterlite Power Secures Transmission Project to Evacuate 4.5 GW of Renewable Energy

Resonia (Sterlite Power) Wins PFC Consulting's Transmission Project to Evacuate 4.5 GW from Ananthapur-II REZ

Resonia Limited (formerly Sterlite Grid 32 Ltd.), a subsidiary of Sterlite Power, has secured PFC Consulting’s transmission project to augment the interstate transmission system at the Ananthapur-II Renewable Energy Zone (Phase I) in Andhra Pradesh. The project will facilitate the evacuation of 4.5 GW of renewable energy.

Resonia won the project with an annual transmission charge of ~$52.48 million. The special purpose vehicle structured for the transmission works, Anantapur II REZ Transmission, was transferred to Resonia at #192.33 million ($2.25 million).

The tender for the project was floated in December 2024. Adani Energy Solutions and Power Grid Corporation of India were among the other bidders that qualified during the technical evaluation round.

The transmission infrastructure will enable the immediate integration and evacuation of renewable power from approximately 4.5 GW of generation capacity in the Ananthapur region, which holds a total renewable energy potential of 20 GW. Connectivity approvals have been granted for around 3,500 MW at the Ananthapur-II Power Station—comprising 2,500 MW at the 220 kV level and 1,000 MW at the 400 kV level.

Project Scope and Timeline

The transmission project must be completed within 24 months. It includes the establishment of key infrastructure to support renewable energy evacuation from the Ananthapuram-II Renewable Energy Zone.

Scope of Work:

• Transformer Installation:

  • 4×1500 MVA, 765/400 kV transformers

  • 6×500 MVA, 400/220 kV transformers

  • Both to be installed at the Ananthapuram-II pooling station near Kurnool

• Bus Reactors:

  • 2×330 MVAr (765 kV) bus reactors at Ananthapuram-II PS

  • Provision of two 4,500 MVA sections at the 400 kV level

• Transmission Lines:

  • 765 kV double-circuit (D/C) transmission line from Ananthapuram-II to Davangere, including 240 MVAr switchable line reactors (SLR, convertible) on both circuits at the Ananthapuram-II end

  • 765 kV D/C line from Ananthapuram-II to Cuddapah, including 330 MVAr convertible SLRs on both circuits at the Ananthapuram-II end

• Reactive Power Compensation:

  • Installation of a 300 MVAr Static Synchronous Compensator (STATCOM) at Ananthapuram-II PS

  • 2×125 MVAr mechanically switched reactors to enhance grid stability

This project plays a vital role in supporting India’s clean energy transition. The Ministry of New and Renewable Energy (MNRE) has set a target of 500 GW of power generation capacity from non-fossil fuel sources by 2030. To meet this goal, it has identified an additional 86 GW of renewable energy potential across Andhra Pradesh, Telangana, Karnataka, and the offshore areas of Tamil Nadu.

Transmission Project to Unlock 4.5 GW RE from Ananthapuram as Part of Andhra Pradesh’s 51 GW Potential

Out of the 86 GW of renewable energy potential identified by the Ministry of New and Renewable Energy (MNRE) across southern India, Andhra Pradesh accounts for 51 GW—comprising 20 GW in Ananthapuram, 23 GW in Kurnool, and 8 GW in Kadapa.

The transmission project titled “Transmission System for Integration of Ananthapur-II REZ – Phase-I” is designed to enable the immediate evacuation of 4.5 GW of renewable energy from the Ananthapuram region, as part of the broader 20 GW potential identified in the area.

In parallel, PFC Consulting has recently floated bids to further expand renewable energy evacuation infrastructure. These include:

• A project to enhance the evacuation capacity by 4.5 GW and establish line bays at the Mandsaur substation in Madhya Pradesh.

• A separate initiative to evacuate 3 GW of power from green hydrogen and ammonia projects in the Kakinada region of Andhra Pradesh under a build, own, operate, and transfer (BOOT) model.

These developments are part of India’s strategic push toward achieving 500 GW of non-fossil fuel energy capacity by 2030.
