Norwegian oil & gas firm Equinor has closed a deal to sell half of its interest in two US offshore wind leases to UK peer BP for $1.1bn, in a deal that marks a dramatic entry for the latter in the global market for wind at sea.

The two companies are also establishing a strategic partnership for further growth off the US.

Equinor currently holds 100% in both projects – Empire Wind off New York State, and Beacon Wind off Massachusetts.
