Training course for registry users, 21–22 June 2017

 
 

We are running a hands-on training course for registry users on 21 and 22 June 2017, from 9.30 am to 4 pm, in Auckland. The course is suitable for new registry users and people wanting to gain some knowledge of how the registry works. Attendees will engage in hands-on exercises and role-playing. 

The training course will cover the following:

  • the operation of the registry and lifecycle of an ICP, including the registry roles of distributor, trader and MEP
  • the operation of the reconciliation manager portal to upload and download files, manage trade notifications, and add/edit changes to NSPs and balancing areas.

We need to set up individual workstations for registry access, so total attendance numbers are limited and may also be limited by organisation.

To express interest in attending the course, please email your name and contact details to marketoperations@ea.govt.nz by COB Friday, 31 March 2017 with ‘June 2017 registry training’ in the subject line. 

Places will fill fast, but please do not book flights and accommodation until you have received confirmation of attendance.

Investigator appointed

 
 

We are investigating alleged breaches of the Electricity Industry Participation Code 2010 (Code) by Transpower New Zealand Limited as the grid owner and by MainPower New Zealand Limited (Mainpower).

The breaches were alleged after a fault on the MainPower network on 24 March 2016. The Islington–Southbrook 1, Islington–Southbrook 2, Ashley–Southbrook 1 and Southbrook–Waipara 1 circuits tripped, resulting in a loss of supply to the Southbrook and Kaiapoi substations.

Investigation closed

 
 

We have decided to discontinue the investigation of alleged breaches by Broadspectrum (New Zealand) Limited. The alleged breaches concerned a category 5 metering installation that inaccurately measured raw meter data; the failure to ensure the meter certification was completed by arranging a prevailing load test; and the failure to provide an investigation report to affected participants on the findings of the investigation into the inaccurate metering installation.

Our decision and reasons are available on our website.

Stress test scenarios unchanged for the April–June quarter of 2017

 
 

The stress test scenarios that we previously published on our website will apply for the April–June 2017 quarter. There is no change from the previous quarter.

Certain participants in the wholesale electricity market must apply a set of standard stress tests to their market position. Participants must then report the results to their boards and to the NZX, as the independent registrar appointed by the Authority.

Questions about the stress tests can be directed to marketoperations@ea.govt.nz, with 'Stress test' in the subject line.
