Autoscale uses an Azure subscription to automatically use more v-cores (virtual CPU cores) when the computing load on your Power BI Premium subscription would otherwise be slowed by its capacity. This article describes the steps necessary to get Autoscale working for your Power BI Premium subscription. Autoscale only works with Power BI Premium.

To enable Autoscale, the following steps need to be completed:

  1. Configure an Azure subscription to use with Autoscale.

  2. Enable Autoscale in the Power BI Admin portal

The following sections describe the steps in detail.


  • Autoscale isn’t available for Microsoft 365 Government Community Cloud (GCC), due to the use of the commercial Azure cloud.
  • Power BI Embedded doesn't provide an out-of-the-box vertical Autoscale feature. To learn about alternative Autoscale options for Power BI Embedded, see Autoscaling in Power BI Embedded.

Configure an Azure subscription to use with Autoscale

To select and configure an Azure subscription to work with Autoscale, you need to have contributor rights for the selected Azure subscription. Any user with Account admin rights for the Azure subscription can add a user as a contributor. In addition, you must be an admin for the Power BI tenant to enable Autoscale.

To select an Azure subscription to work with Autoscale, take the following steps:

  1. Sign on to the Azure portal and in the search box type and select Subscriptions.

Enable Autoscale in the Power BI Admin portal

After you've selected the Azure subscription to use with Autoscale, and created a resource group as described in the previous section, you're ready to enable Autoscale and associate it with the resource group you created. The person configuring Autoscale must be at least a contributor for the Azure subscription to successfully complete these steps. You can learn more about assigning a user to a contributor role for an Azure subscription.

[!NOTE] After creating the subscription and enabling Autoscale in the admin portal, a Microsoft.PowerBIDedicated/autoScaleVCores resource is created. Make sure that you don't have any Azure policies that prevent Power BI Premium from provisioning, updating or deleting the Microsoft.PowerBIDedicated/autoScaleVCores resource.

The following steps show you how to enable and associate Autoscale with the resource group.

  1. Open the Power BI Admin portal and select Capacity settings from the left pane. Information about your Power BI Premium capacity appears.

  3. Select the Azure subscription to use with Autoscale. Only subscriptions available to the current user are displayed, which is why you must be at least a contributor for the subscription. Once your subscription is selected, choose the Resource group you created in the previous section, from the list of resource groups available to the subscription. Assign the maximum number of v-cores to use for Autoscale, and then select Save.
