Report builder pricing

I am new to Power BI.

I need to created paginated reports.  Does using Report Builder require Power BI premium?  My data is in the form of CSV/XLSX or can be accessed using REST.  I just need to create reports locally.  

for now I just want to create a report and export as PDF.  I don't think I need to publish to Power BI Service.

This page implies that I need premium: https://powerbi.microsoft.com/en-us/pricing/

This page indicates that a Pro user can create reports: https://powerbi.microsoft.com/en-us/blog/announcing-support-for-non-premium-power-bi-datasets-in-power-bi-paginated-report-builder/
