Case Study: Uniper cuts time-to-insight by 70% and saves over €1M annually with Tableau Software

Uniper cuts speed to insight by 70% and empowers over 500 employees with self-service analytics

Uniper, a leading European energy generation and trading company, faced fragmented data and an IT bottleneck: teams relied on slow, costly IT-generated reports from a legacy data warehouse, which delayed decision-making and produced frequent rework.

Uniper rebuilt its data architecture into the Atonyx platform—a data lake paired with Tableau—enabling self-service analytics for 500+ employees across 30+ departments. Time to insight dropped by about 70%, traders can generate near-real-time reports via Tableau Mobile, and consolidating 120+ data sources eliminated five legacy systems, saving more than €1 million while unlocking new operational and compliance value.
