OSLO, Norway – TGS has issued a numerical weather prediction (NWP) model to assist analysis and operations of wind energy offshore Scotland.

This is a collaboration with Vaisala, designed to create a higher resolution dataset than has been previously publicly available, with coverage over the entire offshore Scotland region.

Results should de-risk certain ScotWind lease areas, TGS claimed.

The partners have reconstructed meteorological conditions over the past 10 years at a spatial resolution of 1 km with an hourly temporal resolution, providing operators with a resource that can evaluate wind conditions at various scales.

Model results are being validated by publicly available measurements to help improve data quality compared to other industry datasets, TGS added.

Katja Akentieva, vp New Energy Solutions at the company, said: “Initial analysis indicates higher average wind speed than predicted by currently available models in the market, further emphasizing the need for additional wind energy assessment in this region. Our next step is to collect more observational data in order to improve the knowledge.”

The NWP model has used Vaisala wind energy weather modeling technology, said to have performed well in benchmarking tests.

Vaisala’s method draws on a combination of mesoscale NWP computer modeling, microscale wind modeling, and proprietary algorithms.
