International renewable engineering consultancy, SgurrEnergy, in collaboration with DNV Kema through the Renewable UK Wind Resource Group, has provided consultation on a framework for the Categorisation of Losses and Uncertainties for Wind Energy Assessments.
The Framework, developed over two years, was released in February at the annual EWEA conference in Vienna and heralds a significant step in the categorisation of technical losses and uncertainties in energy yield assessments.
The Framework proposes the use of common categories for technical losses in analysis of net production estimates and also for use of common categories of uncertainties, for analysis of the probability distribution of the net production. Building on previous work on the categorisation of technical losses by the industry in the US, this framework is the first to address uncertainty categorisation, which is of particular note due to the fact that uncertainty assessment is a key determining factor in project financial viability.
“Adoption of the framework by the participant consultants and developers will make the due diligence process more straight-forward, due to the added transparency it provides for the comparison of studies,” says SgurrEnergy analyst Vicky O’Connor, who sat on the consultation group. “The hope would be that the framework will be adopted by the wider industry community going forward.”
The participant consultants and developers have agreed to report in accordance with the framework. It is envisioned that the framework will lead to easier comparison of studies, in particular in the due-diligence process and also where more than one study is produced for a wind farm. SgurrEnergy is a subsidiary of international energy services company, Wood Group.
