Case Study: Leading International Energy Company achieves targeted marketing and increased customer retention with Teradata analytics platform

Leading International Energy Company - Customer Case Study

A leading international utility with customers in more than 50 countries—including nearly 10 million gas households and hundreds of thousands of electricity and business customers in one market—struggled with fragmented customer data across multiple legacy data marts. Analysts reportedly spent about 80% of their time locating data and 20% aggregating it, making personalized marketing, timely reporting, and customer-retention efforts slow, error-prone, and costly.

The company deployed a Teradata analytics platform and partner BI tools (SAS, Unica, Informatica) to create a single, daily-updated repository, integrating 15+ billion rows (rising to 20+ billion in year one) and shutting down legacy marts—delivered in about ten months. As a result, 200+ analysts now run faster, more accurate queries with less IT support, enabling targeted offers, improved retention and profitability, lower costs, and a scalable foundation for smart‑meter and other big-data initiatives.
