Network Access Quantities

The Network Access Quantity (NAQ) framework, which accounts for constrained network access, was implemented for the first time for the 2022 Reserve Capacity Cycle as part of the WEM Reform program.

The NAQ model is run after the assignment of Certified Reserve Capacity (CRC) and the completion of the trade declaration process. It considers the amount of available network capacity, taking into account network constraints, and allocates NAQs to Facilities up to their respective CRC amount.

The steps used to assign NAQ is described in the Network Access Quantity Model WEM Procedure.

The Constraint Equations form part of the model inputs and is available here Constraints Library. 

Under clause 4.15.16 of the WEM Rules, AEMO is required to publish the inputs and outputs of the NAQ model. For the 2024 Reserve Capacity Cycle and future cycles, please refer to the Market Data Site.
