The AEMC has today published a Draft Rule Determination and Draft Rule for the Application of Dual Marginal Loss Factors Rule change.

The Commission's Draft Rule adopts AEMO's proposed Rule, with some minor amendments.

The Draft Rule allows AEMO to apply two marginal loss factors (MLFs), at those connection points where application of a single MLF would not accurately reflect losses for energy generation and consumption at that connection point. This occurs primarily at connection points where annual levels of generation and consumption approach parity, including connection points with pump storage facilities.

The reasons for the Commission's decisions are set out in detail in its Draft Rule Determination.

Stakeholders are invited to provide comment on the Draft Rule Determination and Draft Rule. Submissions must be received by 26 May 2011.
