The electricity transmission network comprises 5,135 kilometers of overhead and cable lines and 156* substations.
The Estonian electricity system is connected via cross-border DC power lines to Finland and via AC power lines to Latvia and Russia.
To mitigate the systemic risks related to energy security caused by being connected to the Russian electricity system, activities are underway to disconnect the electricity systems of Estonia, Latvia, and Lithuania from Russia's and to join the continental European electricity grid and the corresponding frequency area no later than the beginning of 2025.
