Methods for predicting the likely upper economic limit for the wind fleet in the United Kingdom should be simple to use whilst being able to cope with evolving technologies, costs and grid management strategies. This paper present two such models, both of which use data on historical wind patterns but apply different approaches to estimating the extent of wind shedding as a function of the size of the wind fleet. It is clear from the models that as the wind fleet increases in size, wind shedding...
