Blockage - what is the impact on the wind industry

Understanding blockage effect on wind farm yield

Blockage - what is the impact on the wind industry - breakfast session by DNV GL

Join our breakfast session Blockage – what is the impact on the wind industry at Searcys at the Gherkin in London on Monday 9th December 8am – 10.30am.

Wind-Farm-Scale Blockage Effects
Wind developer, Ørsted recently announced that it had revised its estimates for future energy production of its offshore wind farms as a result of improving its methodology for calculating turbine interaction loss, i.e. the amount by which energy production by a wind farm turbine declines due to the presence of the other wind farm turbines. The announced change was related to a DNV GL paper, which showed that blockage effects cause wind speed reductions upstream of a wind farm that are more pronounced and far-reaching than commonly assumed. 

Turbine interaction models (also known as wake models), used by the industry to estimate future wind farm energy yield, have not typically accounted for this blockage effect. Therefore, it is likely that turbine interaction losses have been underestimated across the industry. 

BREAKFAST SESSION
At this breakfast session DNV GL, alongside an expert panel from Ørsted, the Global leader in offshore wind and Moodys investor services, will debate what this means for the industry, discuss the blockage effect and its impact on the financing of energy infrastructure projects.
