Flex solutions - Northern Coromandel Peninsula

Overview

We invite expressions of interest (EOI) to provide flex solutions to improve the security of the electricity supply to communities in northern Coromandel Peninsula.

The challenge

The northern area of Coromandel Peninsula is supplied by two 11kV feeders – Colville and Kapanga – from Coromandel substation, near Coromandel township. 

A new 11kV link is under construction to connect these feeders and, while this new link will provide some security, we’re wanting to make further improvement for our customers, particularly to cover peak electricity use times.

Our investment plans

To meet demand, in FY29 we plan to reinforce sections of both the Kapanga and Colville feeders to provide a backup supply that can support more load. We have identified this project as one we may be able to defer, providing value for customers, by implementing flex solutions instead. 

The opportunity

We invite expressions of interest to provide on-call flex solutions during times of peak electricity demand in northern Coromandel Peninsula, specifically on both the Colville and Kapanga feeders. 

What we offer

We will pay an agreed retainer for having the flex solution available to us, with additional remuneration each time it is used.  

Our requirements 

Minimum load reduction

A minimum 300kVA load reduction is required to ensure a flex solution is of sufficient scale to be of use. The total load reduction amount can be established over a period of time, but your solution would need to be in place by December 2027. 

Duration

Duration requirements are as set out in the table below. Our preference is for load reduction for the full duration of the demand reduction period, but we would also consider shorter periods, where these periods aligned with the desired load reduction times, with a minimum of two hours.

Demand reduction periods

Load reduction would need to be available at the following times:
