Premium Capacity - free storage space

Hi DavidPi ,

There is no available way to view currently using and available free space.

As a workaround：

The admin portal shows the number of virtual cores (v-cores) that you have used and that you still have available. 

After you have purchased capacity nodes in Microsoft 365, you set up the capacity in the Power BI admin portal. You manage Power BI Premium capacities in the Capacity settings section of the portal.

You manage a capacity by selecting the name of the capacity. This takes you to the capacity management screen.

For more you can refer to Configure and manage capacities in Power BI Premium 

Hope it helps,
