Dataflow question

[PowerBI123456]

I am starting to get into dataflows. If I were to load one of my sources of data into dataflow and then use it in 3 different PBI files which I publish. Would that data be counted 3 times in terms of data storage or just once?

Each dataset/report published with data from the dataflow would each count.  You could consider publishing a single dataset from the dataflow, and then build the 3 reports with the live connection to the dataset (or with composite model, if each has other data sources to integrate).
