This is a Safegrid Case Study.
Background
Vaasan Sähköverkko Oy is responsible for electricity distribution to approximately 75,000 customers in Vaasa and nearby regions. The company actively invests in improving security of supply, energy efficiency, and sustainable development.
With a distribution network spanning hundreds of kilometres, ensuring consistent reliability—especially in overhead lines—requires modern tools that go beyond traditional fault detection. After a successful two-year pilot with Safegrid, the company decided to expand the implementation.
Challenge
Vaasan Sähköverkko faced several operational challenges:
-
Need for faster and more accurate fault detection and location
-
Long outage durations caused by time-consuming fault identification
-
Limited ability to detect early-stage faults before failure
-
Increasing demand for higher grid reliability and service continuity
-
Need to transition from reactive to proactive maintenance practices
Traditional methods were not sufficient to provide real-time insights or predictive capabilities needed for modern grid management.
Solution
Safegrid deployed its intelligent monitoring system across approximately 270 km of the southern distribution network.
Key capabilities:
-
Accurate fault detection and location in real time
-
Faster response and restoration through actionable insights
-
Continuous monitoring with partial discharge detection
-
Predictive maintenance to identify and address issues before failure
Future expansion:
-
Gradual rollout across the entire overhead line network
-
Potential deployment in parts of the underground cable network
Benefits
The Safegrid solution delivers both immediate and long-term advantages:
-
Improved grid reliability and stability
-
Shorter outage durations and faster restoration
-
Early fault detection, reducing risk of major failures
-
Cost savings through preventive maintenance
-
Enhanced operational efficiency and planning
-
Greater visibility into network conditions
“With good practical experience and a reliable supplier partnership, expanding the cooperation feels natural. We are particularly interested in what kind of opportunities the partial discharge function brings in preventing faults.”
— Jarmo Leppinen, CEO, Vaasan Sähköverkko Oy
Results
Following the pilot phase and initial deployment:
-
Successful validation of Safegrid technology over two years
-
Improved accuracy and speed of fault detection
-
Enhanced ability to prevent faults proactively
-
Strong foundation for wider rollout across the network
Conclusion
The collaboration between Safegrid and Vaasan Sähköverkko demonstrates how utilities can modernize their infrastructure through advanced monitoring and predictive technologies. By moving beyond traditional methods, the company is building a more resilient, efficient, and future-ready electricity network.
With phased expansion underway, Vaasan Sähköverkko is well-positioned to further improve reliability, reduce outages, and deliver consistent value to its customers through intelligent grid management.
