Using Autoscale with Power BI Premium

Power BI Premium offers scale and performance for Power BI content in your organization. With Power BI Premium Gen2, many improvements are introduced including enhanced performance, greater scale, improved metrics. In addition, Premium Gen2 enables customers to automatically add compute capacity to avoid slowdowns under heavy use, using Autoscale.

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 Gen2.

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

  • Select and configure an Azure subscription to use with Autoscale
  • Configure Power BI Premium to use the selected Azure subscription for Autoscale

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.
  • Embedded Gen 2 does not provide an out-of-the-box vertical autoscale feature. To learn about alternative autoscale options for Embedded Gen2, see Autoscaling in Embedded Gen2

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. Log into the Azure portal and select Subscriptions from the left pane. In the following image, the highlighted subscription is called Pay-As-You-Go.

  3. The Create a resource group window appears, where you can name the resource group. In the following image, the resource group is called powerBIPremiumAutoscaleCores. You can name your resource group whatever you prefer. Just remember the name of the subscription, and the name of your resource group, since you'll need to select it again when you configure Autoscale in the Power BI Admin Portal.

  4. When you're satisfied with the name of the resource group, select the Review + create button in the bottom left corner of the portal pane. Azure validates the information, after which you select the Create button to create the resource group. Once created, you receive a notification in the upper-right corner of the Azure portal, similar to the following:

Okay, you've selected the Subscription in the Azure portal that you'll use for Autoscale, and created a Resource group for that subscription. The next step is to enable Autoscale in the Power BI Admin portal, and link it to the resource group you just created.

Enable Autoscale in the Power BI Admin portal

Once 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.

The following steps show you how to enable and associated 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 is displayed.
