Elering and Fingrid begin planning of third submarine cable connection between Estonia and Finland

On Tuesday, 28 June 2022, the Estonian and Finnish transmission system operators Elering and Fingrid signed a memorandum of understanding in which the TSOs agreed to launch the planning of the third submarine cable connection between Finland and Estonia.

"Additional transmission capacity is needed to improve the integration and security of supply of the electricity market in the Baltic Sea region and to contribute to the achievement of climate and renewable energy targets," says Jukka Ruusunen, CEO of Fingrid.

The capacity of the EstLink 3 connection is estimated between 700 and 1,000 megawatts. The new connection is expected to be completed by 2035.

There are currently two high-voltage direct current transmission links between Estonia and Finland - EstLink 1, completed in 2006, and EstLink 2, completed in 2014, with a combined transmission capacity of 1,000 megawatts.

Fingrid is also currently building the new Aurora line electricity transmission connection between Finland and northern Sweden. The connection will be fully completed in 2025. There are also plans to build a fourth interconnector with Sweden, Aurora Line 2, in the early 2030s.
