Abstract

In the wind energy industry, pre-construction yield assessment results are currently exchanged mainly in the form of written (PDF) reports, sometimes complemented by ad-hoc table formats (e.g. MS Excel spreadsheets). Whilst a written report is a very effective format for conveying a full narrative to a human reader, it is often cumbersome to extract large amounts of numerical data. The Energy Yield Assessment Digital Exchange Format (EYA DEF) is being developed as part of the IEC 61400-15-2 standard as a complement to the traditional written report, with the aim to facilitate automated exchange of EYA reporting data between computer systems. The EYA DEF builds on the standardisation developed for the written report in the IEC 61400-15-2 standard. It organises key reporting data into a hierarchical data model in the form of a JSON Schema, the most popular and widely used schema language for this type of use case. The EYA DEF JSON Schema tells the sender of the data exactly how the data should be formatted and the receiver what to expect, and it facilitates data validation. Consider the following example, which assumes that the relevant stakeholders have adopted the EYA DEF. A project developer will be able to receive results from its consultants as EYA DEF JSON documents (in addition to the written reports). He or she can then immediately load all data into the relevant internal applications (e.g. project financial models), and compare results between different consultants and with internal results. Then the developer can share the EYA DEF JSON documents with lenders, investors and any other financial institutions who require the information to evaluate the project. They in turn will all be able to pull the data they need without the requirement for any manual data processing. The same goes for other project stakeholders who require EYA reporting data. The presentation will introduce the EYA DEF, explaining to the audience how it is structured, how and for what applications it can be used and where to get started.
