What if I don't have a power supply available?
To get connected to the MainPower network, you need to have a suitable power supply to your site. If you don't have a power supply or you are not sure, you will need to complete a new power supply request.
Where can I get a temporary power supply from?
Temporary supply connections give builders and other tradespeople access to electricity supply at a worksite where temporary power is required.

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.
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 callouts?
MainPower provides a 24-hour fault response service. When a customer’s property or actions have caused the fault, the responsible customer will be charged a call out fee.
Call outs caused by a MainPower network fault will not incur a fee.
MainPower call out fees
- During normal working hours (7:30 a.m. – 5:00 p.m. Monday-Friday)
- $176+GST minimum for up to two hours, plus travel (charged per kilometer)
- Additional charges will be billed for any equipment required (e.g. replacement power pole) and time exceeding the initial two hour call out period. Additional time between 7:30am-5pm will be charged at our standard rate ($88+GST per hour).
- $264+GST minimum for up to two hours, plus travel (charged per kilometer)
- Additional charges will be billed for any equipment required (e.g. replacement power pole) and time exceeding the initial two hour call out period. Time will be charged at our after-hours rate ($132+GST per hour).
All chargeable call outs will incur a minimum fee for a two hour period (travel time inclusive). Where we are required to stand staff down as a result of attendance at a fault we reserve the right to charge a stand down fee.
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 happens if I need to increase my capacity?
MainPower charges for increasing capacity at an ICP (Installation Control Point, i.e. where the house, shed etc. connects to the network). Please contact us to discuss these charges.
To start the process, check that the wiring inside your house or business is capable of taking the increased current. You electrician will be able to help you with this.
Why do you charge for capacity upgrades?
In some cases, in order to increase the load at an existing ICP (Installation Control Point, e.g. house or shed), MainPower will be required to carry out significant upgrades to the electricity distribution network (e.g. upgrading the transformers, power lines etc. supplying the ICP). This can incur a significant cost.
In order to cover this cost, MainPower charges for all capacity increases. This fee contributes towards any network upgrade work that may be required as a result of the specific capacity increase, or other capacity increases in the future. In this way, no single customer ends up being charged for the entire cost of a network upgrade, but rather the cost is spread across all customers who will benefit.
Why would I need to increase my capacity?
If you are thinking about altering the heating source within your home (e.g. going from a log burner, to multiple heat pumps) or you wish to run extra appliances from your home (e.g. charging an electric vehicle, or a spa pool), you may need to increase your capacity in order to meet the added demand of such appliances. Your electrician will be able to advise you on what will be required. MainPower are happy to work with your electrician, or to provide you with information directly.
