, India. The project was commissioned by Adani Power. With a generating capacity of 648 MW_p at a single location, it is the world's 12th largest solar park based on capacity. ABB commissioned five sub-stations to connect the solar park with the National Grid on 13 June 2016. The Kamuthi Solar Power Project was completed on 21 September 2016 with an investment of around . 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. Construction of the structures needed to mount the solar panels required 30,000 tonnes of galvanised steel. Around 8,500 workers installed an average of 11 MW of capacity per day to complete the project within 8 months. The entire solar park is connected to a 400 kV substation of the Tamil Nadu Transmission Corp. The solar panels are cleaned daily by a self-charged robotic system. Given the solar resource of around 2100 kWh/(m²*yr) an annual generation of 1.35 TWh/yr may be possible. This corresponds to a capacity factor (or average power) of 24% of the peak capacity 648 MW_p. Assuming a technical life time of 25 years the investment cost is 700 MUSD/(25*1.35 TWh) = 2 US cent/kWh.

Controversy

The plant relies on approximately 200,000 liters of water to keep its 25,000 modules clean each day, which has apparently been sourced from borewells nearby without consent of the respective district authority.
