Kamuthi Solar Power Project is a solar park spread over an area of 2,500 acres (10 km2) in Kamuthi, 90 km from Madurai, in the state of Tamil Nadu, India.[1] The project was commissioned by Adani Power.[2] With a generating capacity of 648 MW at a single location, it is the world's second largest solar park.[3][4]

ABB commissioned five sub-stations to connect the solar park with the National Grid on 13 June 2016.[5][6] The Kamuthi Solar Power Project was completed on 21 September 2016 with an investment of around 4,550 crore (US$710 million).[7] The solar plant consists of 2.5 million solar modules, 380,000 foundations, 27,000 metres of structures, 576 inverters, 154 transformers, and almost 6,000 km of cables.[8][9] Construction of the structures needed to mount the solar panels required 30,000 tonnes of galvanised steel.[10] Around 8,500 workers installed an average of 11 MW of capacity per day to complete the project within 8 months.[11][12]

The entire solar park is connected to a 400 KV substation of the Tamil Nadu Transmission Corp.[13] The solar panels are cleaned daily by a self-charged robotic system.[14]

Given the solar resource of around 5.5-6.0 kWh/m2 per day[15] an annual generation of 1.3 TWh/yr may be possible.
