She told the media here that Bharatiya Janata Party (BJP) activists would give "a rousing welcome" to Modi, who she said would also announce various projects for the state.
The Prime Minister would also lay the foundation stone for a new railway line between Dhanushkodi and Rameswaram, Tamilisai said.
Dhanushkodi was declared a ghost town after a cyclonic storm almost wiped out the land strip and destroyed the railway link in December 1964.
Asked about the Tiruvarur Assembly bypoll, caused by the death of DMK President and former Chief Minister M. Karunanidhi, Tamilisai said she would speak about it on Sunday.
