For Power BI Premium, you get 100TB of storage and a data refresh maximum of 48 per day (minute-based schedule that can be refreshed every 30 minutes).
This is useful if you have original data sources that are themselves updated on a schedule. For example, if a PowerPivot data source uses data from a data mart that is refreshed every Monday at 02:00 hours, you can define an inline schedule for the data mart to retrieve its refreshed data every Monday at 04:00 hours.
