Case Study: SSEN Transmission achieves regulatory-ready data governance and 99% asset data consistency with Ataccama ONE

SSEN Transmission reaches 99% asset data consistency with Ataccama

SSEN Transmission, a UK-based electricity transmission operator, faced the challenge of managing critical asset data across disconnected systems like Maximo and ArcGIS. Without a centralized platform, their data governance relied on manual spreadsheets, leading to inconsistencies, significant staff time spent on reconciliation, and an inability to meet the data best practice requirements of their regulator, Ofgem. To address this, they turned to the vendor Ataccama and its integrated Ataccama ONE platform.

By implementing Ataccama ONE, which unified data quality, a data catalog, and a business glossary, SSEN Transmission automated its monitoring and empowered over 100 data stewards. The solution delivered a 15% improvement, achieving 99% cross-system data consistency for a priority substation dataset. This eliminated manual reconciliation work and provided the auditable, measurable data foundation required for Ofgem compliance and future AI initiatives.
