India has built the world’s largest solar power plant, and it did so in record time. The nation’s new facility in Kamuthi, Tamil Nadu, has a capacity of 648 megawatts—nearly 100 more than the Topaz Solar Farm in California, the previous largest.

The solar plant, which spans an area of 10 square kilometers, was built in just eight months at a cost of $679 million.

The facility, which features 2.5 million solar modules, can produce enough electricity to power up to 150,000 homes.

India, now expected to become the world’s third-biggest solar market after China and the US, wants to power 60 million homes through solar energy by 2022.
