Case Study: Fingrid Oyj achieves early fault detection and €5M in avoided repairs with OSIsoft PI System

Investment in a Real-time Condition Monitoring System Pays Off

Fingrid Oyj, Finland’s electricity transmission operator managing roughly 14,000 km of lines and more than 100 substations, needed to improve network reliability while cutting maintenance and capital costs. The core challenge was to monitor and analyze thousands of diverse assets, combine data from SCADA, analyzers and enterprise systems, and deliver a powerful but user‑friendly condition monitoring capability to detect weak-performing components early and optimize maintenance and investment timing.

Partnering with Amitec, Fingrid deployed an OSIsoft PI System–based condition monitoring solution (PI Server, Asset Framework, Event Frames, Notifications, PI ProcessBook) using template-driven hierarchies, automated notifications, element-relative displays and analytics. The system enabled proactive detection of gas leaks and two transformer faults—preventing a catastrophic failure and saving an estimated €5 million—while improving asset utilization, reducing maintenance costs, and optimizing capital investment timing.
