System Operator Response, 8 August 2019:

Conflict of Interest

Transpower as an SOE carries out a role of great significance and value in managing and maintaining New Zealand’s national electricity grid and in co-ordinating the power system. Transpower’s position as system operator and as grid owner puts it in a position whereby our decisions can materially affect the interests of electricity market participants.  Conflicts of interest may arise in the performance of Transpower’s functions.

Local Quality Agreements

Submitted by Tony Neighbours on Mon, 01/08/2016 - 11:32

Transpower as the system operator has agreed to publish the transitional LQA agreement that parties entered into just before the EGRs became effective in 2004.

This was intended to negate the need for a rule change under the EGRs. Publication of this agreement and the schedule will considerably improve transparency for Asset Owners on the voltage profiles that we manage for agreed parts of the grid.

Load Forecasting

Submitted by Tony Neighbours on Fri, 29/07/2016 - 15:02

Background

Transpower as system operator prepares a forecast of demand at conforming grid exit points (GXPs) for each trading period. This information is a key input into the market schedules; in particular, the Week-ahead Dispatch Schedule (WDS), the Non-Response Schedule (NRS) and the Price-Responsive Schedule (PRS).

Load Forecast Methodology

The process and methodology we use to prepare the demand forecast is made available to the Electricity Authority and to the public.

HVDC Transfer

Submitted by Tony Neighbours on Thu, 28/07/2016 - 08:15

What Restricts HVDC Transfer

At times the transfer across the HVDC can be restricted to less than its technical maximum capability due to physical or market conditions.

We are now reporting monthly on what causes restrictions on HVDC transfer. The document below provides background information on HVDC transfer restrictions. The link to HVDC Utilisation Reporting contains the monthly reports within our Market Insights page.
