AIMIM MLA Akbaruddin Owaisi presided over the proceedings as the pro-tem Speaker.
As per the strength of the Assembly, Telangana can have 18 ministers including the CM.
Reddy was instrumental in helping the Congress party defeat BRS in Telangana Assembly polls by winning 64 seats.
For BRS, the defeat was more bitter as its supremo K Chandrashekar Rao lost to the BJP's K Venkata Ramana in Kamareddy in one of his seats.
As it became clear that the Bharat Rashtra Samithi (BRS) would not retain power, KCR sent his resignation to the Raj Bhavan through an official.
Reddy said he expects the BRS's cooperation in giving good governance to the people.
The Chandrasekhar Rao-led Bharat Rashtra Samiti (BRS) has been in power since 2014, when Telangana was granted statehood and won the 2018 elections as well and was hopeful of a hattrick.
The direct contest is between the BRS and the Congress, and both parties have whipped up the Telangana sentiments in good measure during the campaigns.
As many as 2,290 contestants are in the fray for the elections.
Visakhapatnam is also home to the oldest shipbuilding yard.
