Tamil Nadu Transitions from Wind Dominance to Solar Power Leader

As of April 2026, Tamil Nadu's cumulative installed solar capacity reached 13,871 MW compared to 12,159 MW of wind capacity. The state's solar capacity has nearly tripled from 5,067 MW in March 2022, reflecting a 174% growth.

Key factors supporting this expansion include favorable policies, strong industrial demand driven by compliance with European regulations, and advancements in battery storage systems. Meanwhile, the wind sector is focusing on repowering initiatives to enhance generation from existing sites.

However, high land costs and the need for grid modernization pose challenges for future investments. India's grid must adapt to manage increased renewable variability, as highlighted by curtailment levels of 10-30% in high-renewable states due to transmission constraints. Effective grid management and modernization are essential for sustaining the clean energy transition.
