Case Study: Hafslund achieves real-time, scalable smart-meter analytics and fewer maintenance call-outs with Google Cloud Platform

Hafslund Innovating infrastructure for the new smart meter network

Hafslund, Norway’s largest power company and owner of grid operator Hafslund Nett (serving over 700,000 customers), faced a major data challenge when compulsory smart meters began delivering hourly readings and radio-mesh diagnostics. The rollout created high-volume, streaming and new diagnostic data types that required scalable, real-time storage and operational visibility to keep costs and maintenance visits down.

Working with Computas, Hafslund built a Google Cloud solution using BigQuery for streamed analytics, Cloud Bigtable for low-latency transactional queries, and Pub/Sub/Dataflow for ingestion. The platform provides unified, searchable storage and millisecond/microsecond responses, enables real-time customer dashboards, and uses granular diagnostics to pinpoint faults—reducing unnecessary field call-outs and improving maintenance efficiency.
