Indian state-run power utility National Hydroelectric Power Corporation (NHPC) has outlined plans to develop a 600 MW solar PV project at the site of a huge hydropower dam in the state of Maharashtra.

The location identified is the Koyna hydel power complex, which is a 1.9 GW hydro dam run by the Maharashtra State Electricity Board. According to reports by the Times of India, NHPC has begun the process of carrying out feasibility and financial viability tests on the location and the project.

The idea is to install 600 MW of floating PV at the dam, which would not only tie together solar PV and pumped storage, but would be far-and-away the world’s largest floating solar plant in the world if the green light is given.

Located in the Satara district of Maharashtra, the Koyna complex comprises four dams and has a total capacity of 1,960 MW. NHPC technical director Balraj Joshi told the Times of India that the utility wants to "expand our solar portfolio, and we are continuously looking out for opportunities", adding that it had begun examining whether such a grand project could work at the Koyna dam.
