The direct answer
EPC Group has not published a Power BI case study that states a user count above 5,000. Its case summaries record what was delivered and for what kind of organization, and where a summary does not report a user count, EPC Group does not invent one. The largest documented Power BI scopes are for global organizations, listed in the table below with links to each anonymized summary.
What does change at that scale is licensing, and it is Microsoft's rule rather than EPC Group's. On a Fabric capacity of F64 or larger, users who hold only a free license and a viewer role on the workspace can view Power BI content; on capacities smaller than F64, every viewer needs a Pro, Premium Per User or individual trial license, and Microsoft describes Premium Per User as cost-effective for fewer than 250 users (Microsoft Learn, Understand Microsoft Fabric licenses and capacity, accessed 2026-10-26). A rollout to thousands of viewers is therefore a capacity decision, a workspace and security design, and a governance model before it is a report build, which is the order EPC Group's Power BI consulting works in.

Frequently Asked Questions
Does EPC Group have a Power BI case study with more than 5,000 users?
EPC Group has not published a case study that states a Power BI user count above 5,000. Its anonymized summaries record what was delivered and for what kind of organization; where a summary does not report a user count, EPC Group does not supply one.
What changes in Power BI licensing when viewers number in the thousands?
EPC Group plans large viewer populations around Microsoft’s capacity rule: on a Fabric capacity of F64 or larger, users with a free license and a viewer role can view Power BI content, while below F64 every viewer needs a Pro or Premium Per User license (Microsoft Learn, accessed 2026-10-26).
Where can I see the source documents behind EPC Group’s Power BI work?
EPC Group publishes named records, with the contract, Statement of Work or payment evidence and a stated verification class, in its Evidence Center; engagements whose clients are not named are published as anonymized summaries described by industry and organization size.
