HVDC Russia–Finland (Kernovo–Mussalo) was a proposed high-voltage direct current (HVDC) submarine interconnector to transmit up to 1,000 MW (≈8.7 TWh/year) from Kernovo / Sosnovy Bor (Leningrad Oblast, Russia) to Mussalo, Kotka (Finland). The project was developed by United Power Oy (a special-pu...
In the original project schedule for the 1,000 MW Kernovo–Mussalo HVDC submarine cable, United Power Oy planned that construction of the cable and associated infrastructure would be completed in the 2009–2010 timeframe.
In December 2006, the Finnish Government, acting through the Finnish Ministry of Trade and Industry, rejected United Power Oy’s construction permit application for the Kernovo–Mussalo HVDC submarine cable project. This decision formally refused development consent for the 1,000 MW Russia–Finland interconnector and led to United Power suspending its activities on the project.
In June 2006, a financing agreement for the HVDC Russia–Finland (Kernovo–Mussalo) submarine interconnector, with an estimated project cost of €300 million, was signed with Russia’s state‑run foreign economic bank Vnesheconombank (VEB), providing debt financing support for the proposed 1,000 MW link.

On 21 December 2005, United Power Oy and BasEl, representing 16 Swedish and Finnish companies, signed a preliminary 15‑year electricity supply agreement for the planned HVDC Russia–Finland (Kernovo–Mussalo) submarine interconnector, securing a long‑term offtake framework for power to be transmitted from Russia to Sweden and Finland.
In 2004, United Power Oy, a Finland-based company controlled by Baltenergo (a subsidiary of Rosenergoatom), submitted an official application for a construction permit for the Kernovo–Mussalo HVDC submarine cable and its associated converter station between Kernovo in Leningrad Oblast and Mussalo in Kotka, Finland. This application sought regulatory approval to build the 1,000 MW HVDC interconnector intended to export Russian nuclear power to Sweden and Finland.
In 2003, United Power Oy was established as a Finnish–Russian special-purpose company to transfer electricity from Russia to Finland and other European countries, acting as the project vehicle for the Kernovo–Mussalo HVDC Russia–Finland submarine cable. The shareholders were Baltenergo, Kotkan Energia and a consortium of private investors, forming a joint ownership structure for developing the interconnector project.
In the 1990s, the Russian State Nuclear Power Company Rosenergoatom first proposed the HVDC Russia–Finland (Kernovo–Mussalo) submarine interconnector concept, initiating early development of a 1,000 MW link to export Russian nuclear power toward Finland and Sweden across the Gulf of Finland.
