Wind energy in the United Kingdom: modelling the effect of increases in installed capacity on generation efficiency

- There are proposals to double or even treble the present size of the UK wind fleet.
- A larger wind fleet will be less efficient due to increased wind shedding.
- The extent of this loss in efficiency has not yet been quantified.
- This study uses a novel approach to determine the incremental load factor.
- Marginal efficiency reduces to 63% of its current level should the present size be doubled.
