The project scope includes designing, engineering, manufacturing, supplying, erecting, installing, testing, and commissioning the WTGs with a rating of 2.7 MW or higher and a maximum rotor diameter of 156 meters.

The invitation for bids encompasses three separate blocks.

Block I will have a capacity of 540 MW and 200 WTGs. Block-II is set at 305.1 MW and will comprise 113 WTGs. Block-III is designed for 153.9 MW and comprises 57 WTGs.

Bidders are responsible for the comprehensive operation and maintenance of the entire system, commencing from the project’s commissioning. This includes supplying all necessary spare parts and consumables and repairing or replacing any faulty equipment.

They must obtain the statutory approvals and clearances for power evacuation, grid connectivity, and coordination with state nodal renewable energy agencies, as needed.

NTPC Renewable Energy plans to fund this project using its resources and borrowings.

For each bid submission, the following bid security requirements must be met:

• For Block-I (200 WTG) or Block-I (200 WTG) + Block-III (57 WTG) (Total 257 WTG) or Block-II (113 WTG) + Block-III (57 WTG) (Total 370 WTG), bidders are required to provide an earnest money deposit (EMD) of ₹1 billion (~$12 million).
• For Block-II (113 WTG), bidders must submit ₹200 million (~$2.4 million).
• For Block-III (57 WTG), bidders must submit ₹100 million (~$1.2 million).
