A normal fault situation has caused the disruption in electricity transmission between Finland and Estonia, according to Fingrid. The direct current connection between the two countries, EstLink 1, has been disconnected from the network at the time of disconnection, with power transfer through the connection being approximately 343 megawatts from Finland to Estonia. Fingrid has initiated an investigation into the cause of the disturbance at the Estonian direct current substation.
The investigation process will follow standard protocols for determining the cause of disruptions. Fingrid’s press release assures that operational reliability in Finland’s electricity system has not been affected by this incident. Currently, Finland’s electricity export to Estonia is cut off due to detachment of EstLink 1. Additionally, repair of EstLink 2 has been delayed and is estimated to be out of service until August 31st.
As Fingrid continues to gather information and investigate the disruption, measures are being taken to restore electricity transmission between Finland and Estonia. Once the cause of the disturbance is identified, necessary repairs and adjustments will be made to prevent similar incidents in the future. The priority is ensuring a reliable and stable electricity supply for both countries.
