The Thurrock peaking plant is a site consisting of 99 generating sets (Genset), each installed in a pre-cast concrete enclosure. This site is capable of providing 450MW of power, one of the largest of its kind in the UK. The CFD project completed by our team consisted of running numerous wind scenarios at different speeds and directions for different power outputs. The wind analysis consisted of a meso-scale and a micro-scale simulations, where in the former, a large area including surrounding towns and villages and the Thames were accounted for. The output of this model provided the input for the micro-scale simulation of the wind around the site. The results provided detailed analysis of the impact of wind on the cooling of the engines, as well as any potential de-rating or environmental impact as a result of wind and its interaction with the site.
