NetFix – data driven grid health monitoring tool
Since 2020, NetFix, a monitoring and fault prediction tool, has helped Elektrilevi, Estonia’s largest electricity network operator, prevent close to 300 faults in the country’s electrical grid from malfunctioning, saving time and money.
NetFix is a power health monitoring and fault prediction tool that uses smart electricity meters to collect data. It helps prioritise grid work and optimise the network.
With NetFix, up to 65% of faults in low voltage are predictable, and 90% can be resolved without clients ever realising there was a problem. And solving a problem before it happens is more consumer-friendly and more cost-effective than fixing issues after the fact.
The story of the birth of NetFix
NetFix comes from the digital nation of Estonia. Estonia is far ahead of many countries when it comes to digitisation.
From 2011 to 2016, Estonia’s largest network services provider, Elektrilevi, installed smart electricity meters for more than 650,000 customers. It is responsible for the reliability of the 60,000 kilometres of low and medium voltage lines, of which 30% are overhead lines that are exposed to the elements. Every year, approximately 7,700 faults are detected, which accounts for 64% of the total number of faults in low voltage.
NetFix was developed to help identify low-voltage network defects that affect network quality and cause malfunctions and interruptions. It uses Elektrilevi’s smart electricity meters to identify issues and get to the heart of their root causes.
Before NetFix, anomalies would go undetected for months until they finally caused grid failure. This would result in customers calling to complain about service outages. Then, Elektrilevi would have to analyse the problem before working to fix it, and in some unfortunate cases, the customer’s equipment may become damaged or may result in fire, which then must be compensated to the customer.
With NetFix, anomalies are detected and monitored, then preventative work is carried out as needed to repair the grid before it fails. This not only keeps power outages from happening but also increases the safety of the grid. And ultimately saves time and money.
