To assist in the development of a uniform national inter-regional transmission charging methodology, the AEMC has published a Discussion Paper. This Discussion Paper is intended to test the various options with stakeholders to inform the AEMC's assessment of whether any of these options for developing a uniform national inter-regional transmission charging regime are consistent with the National Electricity Objective.
The options proposed in the Discussion Paper include:
- Modified Load Export Charge - similar to the original Load Export Charge proposed in the draft Rule determination which would be applied on a region-by-region basis, except the calculation of the inter-regional transmission charge would be based on a single national transmission charging methodology;
- Cost Sharing - the costs of assets used for inter-regional flows would be shared across TNSPs in the NEM; and
- NEM-wide CRNP - similar to the Modified Load Export Charge, except a single charging methodology would be applied once across all regions in the NEM as opposed to being applied separately on a region-by-region basis.
The AEMC seeks stakeholder submissions on the Discussion Paper by 23 September 2011.
