Bondada Engineering has received a letter of award (LoA) from Tamil Nadu Green Energy Corporation (TNGECL) to establish standalone grid-scale battery energy storage systems (BESS) with a total capacity of 400 MWh (200 MW×2 hrs) at Vellaviduthi and Thennampatty in Tamil Nadu. This project represents the highest storage capacity order in the company’s history, marking a significant stride toward its vision of achieving 10 GW of green capacity by 2030.

Under a build-own-operate (BOO) model awarded through tariff-based competitive bidding with state viability gap funding (VGF), Bondada will deliver complete two-cycle charging and discharging capabilities for on-demand grid support. The initiative aims to enhance grid stability, integrate intermittent renewable generation, and manage peak power demand, thereby accelerating Tamil Nadu’s clean energy transition. “This project marks a key milestone for Bondada Group in the energy storage segment and reflects our strong commitment to advancing India’s clean energy ecosystem,” said a company spokesperson.

Execution is scheduled within 18 months from the signing of the battery energy storage purchase agreement. As a domestic EPC contractor, Bondada’s successful bid underscores its growing leadership in large-scale battery storage solutions across India. The broad consideration for this order will be Rs 836 crore over a period of 12 years.
