Case Study: ESB Group achieves 21% data reduction and €100K savings with SAP HANA

Reducing the Data Footprint by 21% with Expert Advice from SAP Enterprise Support

ESB Group, the Dublin‑based utility that manages Ireland’s electricity network and is building nationwide telecom sites while serving the Republic of Ireland, Northern Ireland, and Great Britain, faced oversized SAP databases that were degrading software performance, complicating archiving, and threatening future growth and a planned migration to SAP HANA.

With SAP Enterprise Support, ESB implemented improved backup processes, database‑management and size‑reduction strategies, archiving tools, and continuous quality checks across six production systems. The program cut the SAP data footprint by 21% (about 3.7 TB), saved roughly €100,000, boosted system performance, and reduced the need for additional storage while better positioning ESB for future initiatives.
