India now boasts of the world’s largest solar power plant with the completion of its new facility in the southern India state of Tamil Nadu.

India’s new solar power plant in Kamuthi town has a capacity of 648 MW, spread over 10 square kilometers (almost 4 square miles). The area it covers has allowed it to surpass the Topaz Solar Farm in California — which has a capacity of 550 MW — taking the title of the world’s largest solar power plant at a single location.

Funded by Adani Green Energy, a part of India’s leading business house Adani Group, the solar power plant in Kamuthi entailed an investment of Rs 4,550 crore (approximately $679 million). Built in an impressive time frame of eight months, the plant is cleaned every day by a robotic system and charged with its own solar panels. It is expected to power 150,000 homes.
