Case Study: Hafslund achieves faster turbine fault diagnosis with Visplore

Hafslund cuts turbine shutdown diagnosis to under 30 minutes with Visplore

Hafslund, a major hydropower operator in Norway, faced a challenge in quickly diagnosing anomalies across its fleet of 160 turbines. When an alert was triggered in their AVEVA PI Vision system, engineers lacked a fast way to perform a thorough, data-driven root cause analysis, which was a time-consuming process. They partnered with Visplore to implement a direct integration that would enable rapid diagnostics.

The solution from Visplore provided one-click diagnostic templates that launched directly from PI Vision. This integration instantly compared current anomalous events against hundreds of historical situations across dozens of variables, automatically highlighting the largest deviations. For Hafslund, this cut the time from alert to root-cause diagnosis to less than 30 minutes, enabling same-day resolution and proven savings of millions of Euros in avoided failures.
