Built with an investment of Rs45.5bn ($679m), the solar plant is claimed to be the world's largest solar power plant at single location.
The project is connected to Kamuthi substation of electric power transmission system operator Tamil Nadu Transmission Corporation (Tantransco).
Covering an area of around 5,000 acres, the plant features 3,80,000 foundations, 25,00,000 solar modules, 27,000 tons of structure, 576 inverters, 154 transformers and 6,000km of cables.
Adani Group chairman Gautam Adani said: "A plant of this magnitude reinstates the country's ambitions of becoming one of the leading green energy producers in the world.”
Featuring five plants in a single location, the solar photovoltaic project is expected to account for nearly 10% of the country's 7GW installed solar capacity.
The project created 8,500 jobs during its eight months of construction period.
The solar plant is expected to contribute to the Tamil Nadu government’s aim to have 3GW of solar generation capacity.
India aims to increase its installed solar capacity from current 4GW to 12GW by the end of next year and reach 100GW by 2022.
In July 2016, ABB said it has commissioned five substations designed to integrate the 648MW solar project to the national transmission grid.
