TGS has expanded its coverage of numerical weather prediction (NWP) model data for the US offshore wind market
The latest model covers a 400,000 km2 area off the east coast of the US, extending from Massachusetts to North Carolina. It was selected to inform and enhance wind resource assessment in the New York Bight proposed sale notice areas.
The wind energy model was produced in collaboration with Vaisala, which provides weather, environmental and industrial measurements, to create a higher resolution dataset than publicly available, with coverage over the key offshore wind industry focus areas on the US coast.
The model results have been validated by publicly available measurements, including, but not limited to floating Lidar data, to increase confidence and improve data quality compared with other industry datasets. It will be further enhanced with proprietary measurements later this year.
Wind developers and other industry stakeholders can compare their assessment of New York Bight areas with wind conditions over existing leases in their portfolio using the high-resolution data. “This capability facilitates a baseline for future validation and post-award analysis,” said TGS.
TGS said it plans to include NWP models for the US market – and ScotWind leasing round in Scotland – in a comprehensive atlas of public and proprietary wind data resources.
“Combined with TGS subsidiary 4COffshore’s market intelligence database, this provides a powerful resource enabling rapid, accurate evaluation of available data in existing leases, especially for future auctions,” the company said.
TGS vice president new energy solutions western hemisphere Katja Akentieva said, “We are pleased to provide unique solutions and insights to the fast-growing offshore wind industry in the US, enabling customers to reduce their commercial risk and improve their understanding of the energy potential in each lease block. Initial results reveal some interesting variations, spatial and temporal, which may impact various components of the windfarm design, construction and energy output.”
The NWP model utilised Vaisala wind energy weather modelling technology, which relies on a combination of advanced mesoscale numerical weather prediction computer modelling, innovative and efficient microscale wind modelling, and proprietary algorithms.
