India added 1.4 GW of wind energy capacity in the third quarter (Q3) of 2025, a 105% year-over-year (YoY) increase from 706.5 MW in Q3 2024, according to Mercom India Research.

Capacity additions, however, fell 11% compared to Q2 2025.

Quarter-over-quarter installations declined after the expiry of the waiver on interstate transmission system (ISTS) charges. Delays in grid connectivity, limited transmission capacity, and land acquisition challenges also contributed to the slowdown in project execution.

The wind energy sector continued to face supply chain disruptions at both domestic and global levels. In India, limited manufacturing capacity and logistical bottlenecks constrained component availability, while reliance on imported parts, along with shipping delays and fluctuating costs, compounded execution challenges. These factors collectively slowed project completion despite ongoing efforts to accelerate installations.

During the quarter, Gujarat led the capacity additions with 557.2 MW, accounting for 38.5% of the total installation. Karnataka followed, adding 336.7 MW and accounting for 23.2%. Of the remaining 554.9 MW, Madhya Pradesh contributed 253 MW (17.5%). Maharashtra and Tamil Nadu added 246.6 MW (17%) and 55.1 MW (3.8%), respectively.

 

 

In Q3 2025, wind projects that went on stream included ReNew’s 250 MW wind project in Maharashtra, JSW Energy’s cumulative 148 MW of wind projects across various locations in India, and Adani Green Energy’s 124.8 MW project at Khavda in Gujarat.

As of September 2025, the cumulative installed wind capacity stood at 53.1 GW, up 2.8% from 51.6 GW at the end of June 2025.

 

At the end of Q3, Gujarat led the cumulative installed wind energy capacity with 14.3 GW. Tamil Nadu and Karnataka followed with 11.8 GW and 8 GW, respectively.

Maharashtra and Rajasthan rounded off the top five with 5.5 GW and 5.2 GW of cumulative installed wind capacity.

Andhra Pradesh and Madhya Pradesh also had significant cumulative wind installations, totaling 4.3 GW and 3.4 GW, respectively, at the end of the quarter.

The top five states accounted for 84.8% of the cumulative installed wind capacity as of September 2025.

In September, the Government of India introduced the Renewable Consumption Obligation (RCO), mandating that, by FY 2030, 3.48% of designated consumers’ total renewable energy consumption must be sourced from wind power.

In September 2025, Tamil Nadu set the wind renewable purchase obligation (RPO) at 0.67% for FY25, gradually increasing to 3.48% by FY30, as part of the state’s goal to meet 43.33% of its energy requirements from renewable sources by FY30.

In July 2025, Bihar set its wind RPO target at 1.45%, as part of the overall 33.01% renewable energy obligation for FY 2025–26.
