3i Infrastructure plc and Macquarie Capital have invested in the West of Duddon Sands Offshore Transmission Owner (WODS OFTO) in UK.

Specifically 3i Infrastructure has announced it has reached financial close on its £23 million (US$36 million) investment for a 50% holding in the WODS OFTO from Dong Energy and Scottish Power Renewables. The remaining equity in the project will be acquired by Macquarie Capital.
