Case Study: Europe’s Largest Electricity Producer achieves 85% operational cost reduction and streamlined data operations with Denodo Technologies

How a Global Energy Leader Transformed its Operations with the Denodo Platform

Europe’s largest electricity producer and a global leader in low‑carbon energy serving over 30 million customers faced fragmented, manual data processes that slowed marketing campaigns, elongated ticket resolution (consuming 25–50% of resolution time), and hindered the development of new client services that combine internal records with public energy performance Open Data. Data silos and strict governance requirements further complicated cross‑business collaboration and sensitive data management.

The company deployed the Denodo Platform to create a data marketplace and unified semantic layer, federating Hadoop, relational databases and Exadata via JDBC/web services, and delivering real‑time dashboards and self‑service BI while enforcing granular access controls, masking and audit trails. The result: an 85% reduction in operational costs, roughly 75 workdays saved annually in marketing, 74 workdays recovered across ticket management and data handling, faster launches of client energy services, reduced reliance on IT teams, and improved collaboration and compliance.
