Representative Assignments

Technical due diligence, onshore and offshore wind (including floating wind)
Led technical due diligence mandates for major wind power generation projects (exceeding £1.5bn) for blue-chip clients. Includes acquisition assignments, leveraged with project finance, in the run up to financial close and beyond (through construction, operations, refinancing phases).
Merit order assessment
Developed detailed comparison tool for an oil major to rank the expected levelised cost of energy (LCoE) of projects eligible to bid into UK government-backed Contract for Difference (CfD) auction, defining project Capex, Opex, energy yield expectations and schedule assumptions.
Floating and fixed-bottom offshore wind site selection
Engineering lead for multiple site identification assignments for key international developers, coordinating engineering as well as environmental and socio-economic work streams to identify, select, and rank suitable development areas for fixed-bottom and floating wind projects in various global markets.
