Chennai, In a decisive move to bolster grid stability and accelerate the transition toward clean energy, the Tamil Nadu government has officially approved the Tamil Nadu Battery Energy Storage Systems Policy, 2026.
Accordingly, operating under the nodal agency Tamil Nadu Green Energy Corporation Limited , the initiative aims to tackle the complexities of variable renewable generation, optimise grid operations, and significantly reduce power curtailment. By storing surplus electricity during low-demand hours-specifically leveraging solar generation windows-and discharging power during peak demand periods, the policy addresses vital energy security requirements. These incentives apply strictly to eligible projects commissioned within the policy window, provided that the discharged energy is utilised within the State. Through this comprehensive blueprint, the state reinforces its leadership in renewable energy integration and long-term grid resilience, the policy added.
The policy, which was released on Tuesday, sets an ambitious target to deploy at least 2.5 GW, matching a 10 GWh storage capacity across the state during its operative period. To incentivise early adoption and ease financial burdens for developers, the government has introduced a complete waiver of applicable transmission and wheeling charges for a duration of 10 years.
