Hot water load testing under way ahead of winter
Until mid‑April, we’re working closely with retailers to carry out hot water load testing as we prepare our network for the coming winter season.
These tests run for a couple of hours each day, Monday to Friday, with no testing taking place over weekends. Because each test window is relatively short, customers are unlikely to notice any changes to their hot water supply.
The purpose of this work is to help us better understand how much controllable load is available during the summer months. Gaining accurate insights now means we can model customer savings more effectively by reducing system load at peak times. It also helps us assess whether this load flexibility could assist Transpower in deferring an upcoming local transmission upgrade.
This testing is an important part of ensuring a resilient, efficient network that supports our community.
