2009 Grid Planning Assumptions [Closing date: 2009/11/06 17:00:00 GMT+13]

Published 25 September 2009

As part of its duties in overseeing aspects of transmission investment, the Commission is required to publish a Statement of Opportunities (SOO). The SOO must include Grid Planning Assumptions (GPA). The GPA must include long-term peak and energy demand forecasts, and a reasonable range of credible future, high-level generation scenarios. The Commission has made significant progress in developing a new set of  GPA and is now seeking participants’ feedback. With regard to the demand forecasts, the Commission is currently reviewing the underlying model and therefore, most of the feedback sought in the  2009 GPA consultation paper is around input assumptions and methodology of the demand forecasts. The Commission will consult on the demand forecasts later on this year.
