Presentation Description: The US offshore wind industry has taken the significant step of relying entirely upon floating lidar systems as the basis for collecting site-specific wind resource measurements. While the US onshore wind industry is carefully working towards methods and caveats to assessing stand-alone lidar data, the neighboring offshore industry is basing billion-dollar projects on two floating lidar systems per lease area. This measurement approach, combined with the unique metocean environment, requires special consideration and methods when estimating the long-term wind resource characteristics and suitability inputs for an offshore project. In this presentation, Natural Power will describe and demonstrate these site assessment methods, along with associated risks and challenges, through a case study of the Hudson North and Hudson South candidate offshore wind energy areas. NYSERDA deployed one validated Eolos floating lidar system to each of the two candidate NY Bight wind energy areas in the late summer of 2019 as part of a multi-year public campaign. Natural Power will analyze the data sets collected by the two systems utilizing finance-grade methods to assess the measurements, adjust the observations to the long term, and extrapolate the results over the region. Natural Power will describe these methods, as well as the use of regional metocean observations and reanalysis data sets to define the region’s wind resource and suitability input conditions. This presentation will specifically highlight the analytical approaches unique to this campaign and the environment. The results of these analyses – the estimated long term wind resource and key suitability inputs – will be summarized in the context of other US regions and global markets.
Methodology: Natural Power will present this work through a variety of tables, figures, graphics, and narrative description
