Statistics NZ’s latest Consumer Price Index (CPI) release showed the annual rate of change in electricity prices paid by residential consumers was 0.0% (year ending 30 June 2015). The quarter-to-quarter rate of change was 0.6%, which has reversed the -0.2% change in the September 2014 quarter and the -0.5% change in the December 2014 quarter.

Last month we published an information paper that proposed the system operator introduces a facility to share sustained instantaneous reserve across the High Voltage Direct Current inter-island link. Enabling and using such a facility would promote our statutory objective by reducing the quantity of sustained instantaneous reserve procured and increasing competition between instantaneous reserve providers in each island.  This initiative is an interim step for the project to implement a national market for instantaneous reserve.

We have published the two submissions we received and are considering the points they raise.

Market participants were advised by ASX on 22 May 2015 that it will reduce the contract unit of all ASX New Zealand electricity futures and options contracts from 1 MWh (Megawatt Hour) to 0.1 MWh.

ASX has since advised that this change, originally targeted to go live on Monday 27 July 2015, has been delayed to enable additional time for customer readiness. 

ASX will issue a further ASX Notice in the next two weeks that will communicate the new target go live date.
