Marie-Anne is a senior renewable energy expert with almost 15 years of experience in the wind industry. She began her career with Garrad Hassan (subsequently DNV) as a wind energy analyst in 2007 and during the latter half of her time at DNV held the role of technical lead for offshore wind resource and energy yield assessment in Northern Europe.
Over the course of her career, Marie-Anne has provided independent, technical advisory services to onshore and offshore wind farms at various stages of development across a range of markets including the Irish, North and Baltic Seas offshore, and onshore projects in the UK, Ireland, South Africa and the Nordic region.
Marie-Anne has been involved in the delivery wind resource and energy yield related analyses for over 14 GW of offshore wind farms in Northern Europe, many of which are now operational, and has supported offshore projects in the US and Asia. She has also managed industry leading projects with the Crown Estate and Carbon Trust, improving industry understanding of offshore wind resource and reducing LCoE of offshore wind projects.
Throughout her career Marie-Anne has established and maintained long-term customer relationships in the wi nd industry and has substantial experience of working with project developers, owners and investors of wind farm projects and also in supporting due diligence transactions.
