Resonia Ltd has secured the bid for the “Transmission System for Integration of Ananthapur-II Renewable Energy Zone (REZ) Phase-I” project, a significant initiative aimed at integrating 4.5 GW of renewable energy in Andhra Pradesh. The company, formerly known as Sterlite Grid 32 Ltd (SGL32), emerged successful through the Tariff Based Competitive Bidding (TBCB) process in 2025.
Under the project’s framework, Resonia Ltd will develop and operate the transmission system through a Special Purpose Vehicle on a BOOT (Build, Own, Operate, Transfer) basis for a period of 35 years. This achievement marks the company’s 11th power transmission project in India under the TBCB process, reinforcing its presence in the sector. With this latest addition, Resonia now manages projects worth approximately ₹32,527 Crores.
Arun Sharma, CEO of Resonia Ltd, expressed enthusiasm about the project, emphasising its role in expanding the company’s footprint into Andhra Pradesh. He highlighted the project’s importance in strengthening the state’s power transmission network and its contribution to India’s broader goal of integrating renewable energy into the grid. He further stated that this endeavour marks a strategic expansion into the southern states, aligning with the company’s vision for sustainable energy solutions.
The Ananthapur-II REZ Phase-I project involves the establishment of critical transmission infrastructure to facilitate the evacuation of 4.5 GW of renewable energy from the Ananthapur region. The scope includes constructing a large-scale Greenfield Pooling Station at Ananthapuram-II, featuring 765/400kV and 400/220kV capacities. Additionally, the project entails the development of 765 kV D/C transmission lines, extending approximately 150 km from Ananthapuram-II to Davangere and around 200 km to Cuddapah. Furthermore, a ±300 MVAR STATCOM will be installed at the Ananthapuram-II Pooling Station to enhance grid stability and reliability.
