The Wholesale Advisory Group (WAG) has investigated the wind offer regime and found that there are likely to be efficiency gains from applying targeted amendments to address two problems they identified. Accordingly, the WAG considers that the Electricity Industry Participation Code 2010 (Code) should be amended to ensure that offers reflect intentions for availability, and require notice of the withdrawal of wind generation prior to gate closure. We have included a project to evaluate the WAG’s recommendations in our work programme. We will consult on the WAG’s recommended changes as part of the Code amendment process.

The WAG’s recommendations paper is available below.
