ScotWind Offshore Wind Leasing Round

Project title: ScotWind Offshore Wind Leasing Round

Project location: Scotland, UK

Client: Renantis

Project Summary: Beginning in summer of 2020, OWC and ABL Group provided full bid management and structuring for BlueFloat and Falck Renewable’s (now named Renantis) Joint Venture in the ScotWind leasing round. Our clients successfully won three bids and secured seabed lease areas with a total offshore wind capacity of 3.1 GW. OWC has kept supporting the projects in development activities and offshore surveys. 

About the projects

The ScotWind leasing round, hosted by Crown Estate Scotland, was the world’s largest commercial round for floating offshore wind and a huge step forward in putting large-scale floating wind technology on the map at gigawatt scale. The ScotWind leasing round saw 74 applications and the consortia advised by OWC won three projects. Two projects were won alone, 900 MW Broadshore and 1.2GW Bellrock projects, and one in collaboration with Ørsted, 1GW Stromar project. The projects, now under development, aim to be commissioned by 2030-35.

  • New market
