According to the tender document, the selected bidders will be responsible for the complete execution of the project. This includes detailed design, engineering, manufacturing, supply, transportation, erection, installation, testing, and commissioning of the wind turbine generators. The turbines must be selected from the latest Approved List of Models and Manufacturers (ALMM) issued by the Ministry of New and Renewable Energy (MNRE). Each turbine should have a minimum capacity of 3 MW.
