Load Shedding
MLL controls load for a variety of reasons, including minimising our contribution to the loading on the regional transmission grid during peak times, and in response to faults or emergencies.
There are 16 channels that control different parts of MLL’s network. Each channel can be turned on or off separately. If a channel is turned off this means there is no power to your controlled meter (most likely your hot water cylinder). This is what is called load shedding. If the chart below shows there are 16 channels on then there is no load shedding.
Planned Outages
From time-to-time MLL has planned outages on the network to carry out upgrades and maintenance.
The outages allow our teams to work on the network in a safe manner and we always endeavour to organise the shutdowns to be as least disruptive as possible to our consumers. To see our upcoming planned outages please click here.

Hot Water Load Testing Under Way Ahead of Winter
Until mid‑April, we’re working closely with retailers to carry out hot water load control* 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.
*We use our ripple control system to turn off the electrical supply to hot water cylinders connected to the system. We've been doing this for decades, primarily to manage network peaks.
