TPM Development: Residual Charges and the Treatment of Batteries Options Consultation

Residual Charges and the Treatment of Batteries Options Consultation

This consultation sought feedback on how the residual charge should be applied for batteries, and for storage more broadly. We know battery storage is something customers are keen for us to carefully work through, and we want to give it full consideration as we develop a proposed new TPM. See below for the consultation document, and the 14 submissions and 4 cross-submissions received.
 

The Electricity Authority published two relevant documents on 22 March 2021:

Black Start

Black start is the first step in the process of system restoration in the unlikely event of an island-wide black-out.

Black start can only be carried out by a generating station that can self-start without requiring power from the grid. We need to have this service available in both islands so we could re-energise the power system, and allow other generation to connect, following such an event. 

We may enter into black start contracts with parties who can offer the black start service compliant with our technical requirements and the Code.

Upper North Island Loads

Power system loads in the North Island north of Huntly (Zone 1) are displayed on this page to give power companies loading information across the zone.

This information is updated every five minutes. Due to the location of recording equipment at some sites, the load split between retailers for these zones is indicative only.

The historical Zone Load Peaks are winter and summer seasonal values and are reset at the change of seasons on 20 October and 10 May.
