This project is notable in that it is anticipated to provide a precise measurement of neutrino mixing parameters . The project is a multi-institute collaboration and one of the biggest experimental particle physics projects undertaken in India . </P> <P> The project was originally to be completed in 2015 at an estimated cost of ₹ 1,500 crores, has been cleared by the Ministry of Environment (India) for construction in the Bodi West Hills Reserved Forest in the Theni district of Tamil Nadu . Although delayed, the project is underway as of 2015 . </P>
