Main reason for parrallal operation of trasformer is to work without failure because we need power for 24 hours.

If failure occur or in cse of maitanace we can provide power to the consumer.

Also, one reason is that in parralal operation transformer share the total load.So, instead of one transformer if we have two it save total cost as well as the mainance cost coz we can manage with one if other has fualt so, we can atleat give power to the critical load.
