Energy company Equinor and technology company Hitachi Energy have signed a strategic collaboration agreement. It includes developing standardised base designs for transmission systems to connect offshore wind farms to the onshore grid, including high-voltage direct current (HVDC) versions.

The two companies have a longstanding collaboration. Hitachi Energy provided Equinor with power grid connections on projects such as Dogger Bank A, B and C offshore of the UK, and Troll A, the world’s first HVDC power-from-shore connection.

The scope of the agreement covers the complete spectrum of Hitachi Energy’s portfolio of power grid technologies and solutions including its digital twin for high-voltage direct current (HVDC) and power quality solutions, modular and prefabricated offshore and onshore grid connections and grid automation.
