EstLink 1 entered commercial in‑service operation in January 2007 as a 350 MW, ±150 kV HVDC Light interconnector between the Harku substation in Estonia and the Espoo substation in Finland. The project uses 210 km of cable (148 km subsea and 62 km on land) to provide bidirectional power transfer and enhance security of electricity supply and market integration between the Baltic States and the Nordic region.
