Adani Green Energy expands BESS capacity, achieves 70% of FY27 target

The Green Energy Corridor Phase-III scheme, approved by the Union Cabinet on September 30, aims to support India's ambitious renewable energy push by establishing transmission infrastructure to accommodate up to 135 gigawatts (GW) of clean power. With a budget of Rs 1,86,405 crore, the phase III scheme is slated for completion by FY33 and focuses on augmenting intra-state and inter-state transmission networks through Intra-State Transmission Systems (ISTS) and Inter-State Transmission Systems (ISTS).

The primary objective of the Green Energy Corridor Phase-III is to alleviate transmission bottlenecks, which have been a significant hurdle for India's renewable energy sector. In FY26, around 6,900 gigawatt-hour (GWh) of clean electricity faced curtailment due to transmission constraints, as reported by the government. By bolstering transmission capacity, the scheme intends to tackle intermittency issues and increase the grid's resilience during peak demand periods.

Moreover, the scheme includes a dedicated battery energy storage (BESS) component, with provisions for deploying 50 GWh of BESS at renewable energy developer/generator sites or other critical grid locations. This storage capacity is intended to address the intermittency problem and ensure a stable power supply during non-solar hours.

The Central Financial Assistance (CFA) of Rs 54,082 crore allocated for the scheme will help offset intra-state transmission charges, ultimately benefiting end-users and promoting the adoption of renewable energy at a lower cost.
