STV plans to deliver all three services in partnership with educational institutions to provide media students with the opportunity to learn and train in a live TV environment.
The broadcaster will work with Robert Gordon University and North East Scotland College in Aberdeen, the University of the West of Scotland (UWS) in Ayr, and Abertay University and Dundee and Angus College in Dundee.
STV will deliver local news and current affairs content for all three services.
Bobby Hain, director of channels at STV, said: “STV is committed to delivering local content for viewers in Scotland and the award today of three additional TV licences will serve to complement our existing STV family of broadcast, online and mobile services. Local TV is a long term commitment for STV and we look forward to working with our education partners in Aberdeen, Ayr and Dundee to deliver these new services.”
