WDRM Predictability of Load (PoL) Calculator

A NMI must have and maintain a predictable load to be eligible to participate in WDR. This is so baseline energy can be accurately estimated and the NMI can be shown to satisfy the baseline compliance standard. The “predictability of load” (PoL) calculator has been developed to help participants estimate their NMIs' PoL. 

As part of the registration and classification processes, each NMI in a WDRU must individually qualify based on a PoL assessment (baseline eligibility assessment). AEMO also uses PoL assessment to ensure the WDRU remains baseline compliant (baseline compliance testing). 

For PoL assessment, AEMO uses a series of baseline calculations from relevant days in the NMI’s recent history to return two outputs - one accuracy and one bias score - measuring PoL. PoL is determined by whether the accuracy and bias metrics for the NMI/WDRU, meet the accuracy and bias thresholds. This is calculated for the specified baseline methodology using historical data for the load according to the relevant baseline eligibility assessment rules or baseline compliance testing rules for that baseline methodology. The Baseline Eligibility Compliance and Metrics Policy establishes the methodology by which AEMO will determine baseline eligibility and compliance under the WDRM and sets out the thresholds for baseline compliance metrics. 

The PoL Calculator provides Demand Response Service Providers (DRSPs) the ability to estimate a NMIs' indicative bias and accuracy metrics prior to registration. The calculator provides accuracy and bias scores for a NMI: 

Using this tool is voluntary. It is intended to provide indicative scores for a NMI’s PoL to assist participants in determining: 

  • Which NMIs to include in their application, 
  • What methodology might best suit their profile, and 
  • How the baseline results differentiate between the four available methodologies. 
  • Information on available methodologies and the parameters that distinguish them can be found in the Baseline Methodology Register

The calculation logic and formulae used by the PoL Calculator to produce accuracy and bias scores can be reviewed in the Baseline Eligibility Compliance and Metrics Policy. There are three variable inputs to this tool: 

  • Meter data (provided by the participant) 
  • Selection of baseline methodology from a drop-down menu  
  • Selection of the NMI’s NEM region from a drop-down menu, which is used to identify regional public holidays
