Transmission pricing methodology (TPM) review: second issues paper: Question and Answer session on CBA calculations


As announced in our Market Brief on 14 March 2017, Oakley Greenwood (OGW) will be running an online Question and Answer session on Tuesday 28 March via an email group.

Electricity Authority/system operator joint development programme published


The Electricity Industry Participation Code 2010 requires the Electricity Authority and the system operator to agree, and for the Authority to publish, a joint development programme at least annually. 

The programme coordinates and prioritises the following:

  • those items in the Authority's industry development work plan on which the Authority intends to liaise with the system operator
  • the system operator's capital expenditure plan provided to the Authority under the system operator market operation service provider agreement.

We have recently agreed updates to the programme that reflect progress, changes to priorities, and other project agreements that have occurred since we last published the programme in August 2016.  

We have published the updated programme on our website.

Please email any questions about the programme to info@ea.govt.nz.
