Statnett wishes to reinvest in two subsea interconnectors in the inner Oslofjord. One will connect Solberg in Hurum and Brenntangen in Vestby Municipality (Solberg-Brenntangen) and the other Filtvet in Hurum and Brenntangen in Vestby Municipality (Filtvet-Brenntangen).

The subsea cables are necessary for ensuring good power supply in central Eastern Norway. The existing interconnectors were built in 1975 and 1958. The projects will also contribute to value creation by ensuring power exchanges to and from Sweden.

The Norwegian Water Resources and Energy Directorate (NVE) has granted Statnett a licence for new sea cables across inner Oslofjord. The decision involves the construction and operation of seven 420 kV subsea cables and two new cable terminals on each of the Solberg-Brenntangen and Filtvet-Brenntangen cable interconnectors.
