The swearing-in of the new ministers would take place at 11 AM on Tuesday at the Raj Bhavan, a state government release said.
The Telangana Cabinet presently consists of 12 members, including the Chief Minister, and there is scope for inducting six more.
At present, key portfolios like power, energy and urban development are held by Rao himself and some ministers are also holding additional charges.
Rao had recently indicated that members of the ST community would have a representation in the Cabinet.
Currently, it is an all-male Cabinet and a woman member is likely to find place in the council of ministers.
The names of Jupally Krishna Rao, Laxma Reddy, Konda Surekha, Chandulal, Ramulu Naik, Tummala Nageswara Rao and Talasani Srinivasa Yadav are doing the rounds in political circles as possible contenders for the berth.
However, Nageswara Rao, a senior leader from Khammam district who joined TRS from TDP, is not a member of the either House of Legislature.
