  1. Wind Generation in the SEM: Policy for Large-Scale, Intermittent, Non-Diverse GenerationInitial Response to Comments and Next Steps Juliet Corbett, Aoife Crowe 17 October 2008

  2. Background On 11th February 2008 the SEM Committee published a discussion paper on the treatment of wind generation (SEM/008/02) in the Single Electricity Market (SEM) in the context of non-diverse intermittent generation in general.

  3. Issues addressed • the processes by which the System Operators (the SOs) create a secure economic dispatch, including the definition of the term ‘curtailment’ in this context; • the compensation of wind generation with and without firm access, when constrained down, in comparison to conventional generation; • the calculation of the market System Marginal Price, and • the remuneration of wind generation within the capacity payment mechanism.
