Outages FAQS

What should I do during a planned power outage?

If you will be affected by a planned outage, your electricity retailer will send you a letter in advance, so you can make other arrangements.

Planned outages are also listed on our website, visit the planned outages page.

What should I do if I have no hot water?

After an outage, it can take up to 6 hours for a hot water cylinder to reheat once power has been restored after an outage. If you have no hot water:

  • Check that your hot water cylinder is on.
  • If your hot water cylinder is heated by gas then contact a registered plumber.
  • If your hot water cylinder is heated by electricity then please call MainPower on 0800 30 90 80.


What is ripple control?

MainPower may use ripple control at times to manage load on our network. If you have a ‘controlled circuit’ in your home it will probably be connected to your hot water cylinder. The ripple relay is used to switch water heater power off at peak times - like on cold winter nights when demand for electricity is highest and at times when faults mean less power is available in the local area. If you are on a controlled rate this will show on your electricity bill, you will usually receive a cheaper electricity rate if you are on a controlled tariff.


MainPower provide a 24 hour fault response service. Please note, some fault response services may incur a cost, though this is generally only the case when the customer's property or actions have caused the fault.

Who is a priority customer?

Special consideration is given to the continuity of supply to customers whose health or livelihood could be adversely affected by an interruption. Priority customers include those who maintain essential services as well as medically dependent customers.


Customers with serious medical conditions, who rely on continuity of supply to support life, are treated as priority customers. Every effort is made to maintain continuity of supply and, if necessary, to advise them of any interruptions to supply so that alternate arrangements can be made. If you are a medically dependent customer, please ensure we are aware of your needs. You can provide this information online. Or, contact us on 0800 30 90 80.

Why do power outages occur?

There are two types of power outage, planned and unplanned.


Planned power outages occur when we need to complete maintenance work on the network. If you will be affected by a planned outage, you will receive a notification from your chosen electricity retailer in advance.


Unplanned power outages occur when unforeseen circumstances cause damage to the network (e.g. car accidents, tree branches or other debris being blown into power lines etc.).

Does MainPower charge for no-power callouts?

MainPower provide a 24 hour fault response service. Some fault response services may incur a cost, though this is generally only the case when the customer's property or actions have caused the fault.

Does MainPower control irrigator load?

Irrigators on the MainPower network may be connected to our emergency load control system. Houses, sheds etc. are not connected to the emergency load control system.


Across our network, irrigators can use a large amount of electricity. In situations where MainPower needs to decrease the load on the network, we may turn off the electricity supply to irrigators. This is to ensure continued supply across the region and only happens in extremely rare, emergency situations. If it is necessary to turn off irrigators, MainPower will try to contact affected customers, however this may not always be possible in short-notice, emergency situations.


What can my business do to be prepared for a power outage?

  • Check your terms and conditions with your electricity retailer - it will detail notification periods for planned electricity network outages and any compensation clauses.
  • Check your insurance provisions – how long does power need to be off before the policy covers you.
  • Have a good back up plan and ensure your staff are trained.
  • Consider the use of manual eftpos and credit card options.
  • Can your site be supplied by a generator – know your capacity requirements, connection options and generator hire contact details.
  • Have alternative locations for storage of perishable goods and freezer blankets.
  • Have back-up alternative locations to work from and phone diversions to mobiles contingency in place and when the power comes on understand what equipment needs resetting.
