EstLink 2 is the second high-voltage direct current (HVDC) connection between Estonia and Finland, significantly increasing electricity transmission capacity between the Baltic and Nordic regions.

EstLink 2 is owned by Estonian company Elering AS and Finnish company Fingrid Oyj in equal parts. With a capacity of 650 MW, it covers up to half of Estonia's winter electricity demand, effectively integrating Estonia and Finland into a single market. The total length of EstLink 2 is approximately 170 km.

On 25 December, EstLink 2 suffered an emergency shutdown due to suspected external damage. Since then, preparations for repairing the damaged subsea cable have been ongoing, but key challenges remain.
