Update to NEM load table (Unmetered Loads) – current proposals

Proposal to Update NEM Load Table (Unmetered Loads)

Following the migration from the Jurisdictional Metrology Procedures to the NEM Metrology Procedure, the obligation to update and publish the Load Tables for Type 7 Metering Installations (NEM Load Table) lies with AEMO.

The NEM Load Table sets out the power consumption values for each unmetered device type.  These power consumption values are used in the algorithm that calculates metering data for unmetered loads in the NEM.

As per clause 12.1.4(d) of the NEM Metrology Procedure Part B AEMO is required to:

  • Consider and publish proposals to add an unmetered device type to the NEM Load Table.
  • Take into account the views of interested parties to determine whether to add an unmetered device type to the NEM Load Table.

The following process will be used to amend the NEM Load Table:

  • Publish the supporting documentation for the proposed new unmetered device load value on the AEMO website for comment and agreement by industry.
  • Period for comments on the proposed unmetered device load value will be 20 business days.
  • In the absence of any comments that dispute these proposals, AEMO will take the proposed load for the unmetered device type as agreed.
  • The new unmetered device load value agreed and published in the NEM Load Table may only be used exactly as tested.
  • The new unmetered device load value agreed and published can be used in all NEM jurisdictions that have declared street lights as market loads.

AEMO invites comment as to the acceptance of this new unmetered device load value into the NEM Load Table as per clause 12.1.4(d) of the NEM Metrology Procedure Part B.

Aldridge Traffic Systems Berlin 17W LED Luminaire

Aldridge Traffic Systems has applied to have its Berlin 17W LED luminaire added to the NEM Load Table as an unmetered device and has proposed the following amendment to the NEM Load Table:

Jurisdiction Submitted by Unmetered device Load as tested (W)
ALL Aldridge Traffic Systems Berlin LED Luminaire 17W
19.1W

AEMO has considered the Aldridge proposal against the minimum requirements to add new unmetered device types to the NEM Load Table (as set out in clause 12.1.4(d) of the Metrology Procedure Part: B) and concludes that this proposal fulfils these minimum requirements.
 
The Aldridge proposal, including supporting test results, technical summary and letters from Lend Lease supporting the installation of this device are published on this web page.
 
Please direct all comments to David Ripper, Principal Metrology Engineer, NEM.UML@aemo.com.au
  
Date of publication: 9 January 2020.
 
Reponses to be submitted by no later than 10 February 2020.
