Horizon Power Expert Guide

Horizon Power supplies power to over 110,000 homes and businesses in remote and regional WA, over an area of 2.3 million square kilometres. Its network runs across most of the state, heading as far north as Kununurra and as far south as Hopetoun. Horizon Power is Australia’s only ‘vertically integrated utility’ which means it operates across the full electricity supply chain – from generation to retail. In other states and territories, this process is divided into different sections, with groups such as electricity distributors and energy retailers, generally only taking care of one supply element. However, Horizon Power claims it is looking to transition “from a one-way linear relationship towards community energy exchanges”.

Some of the general services Horizon Power provides to customers include:

  • Answering energy bill enquiries and collecting payments
  • Network gird and power line maintenance
  • Connecting new customers to the grid
  • Connecting solar, batteries and electric vehicle chargers to the grid
  • Restoring power outages or supply interruptions
  • Repairing fallen or faulty power lines
  • Meter reading

Horizon Power App

The Horizon Power App is available for customers to download from the App Store and Google Play. This app allows bill-payers to access information regarding their usage, solar energy generation (if they have solar), billing information and power outages. Residential customers can also use the app to pre-purchase energy on specific tariffs. Horizon Power customers will need to use the same details as listed on their ‘My Account’ in order to access data on the app.

Electricity Tariffs on the Horizon Power Network

Horizon Power’s electricity tariffs are simple and practical with no discounts or gimmicks. There are two standard residential electricity tariffs and four business electricity tariffs.

Horizon Power’s standard residential electricity tariffs are the ‘A2 Residential Tariff’ and the ‘K2 Combined Use Tariff’. As the respective names suggest, the A2 Residential Tariff is your basic electricity deal. Customers on this tariff are charged a single rate for electricity, regardless of the time of day they use power or the amount of energy used. The K2 Combined Use Tariff is for customers who operate a home business. This includes farms, home surgeries, caretaker residences and more. To be eligible for this tariff, however the combined energy usage from the home and business cannot exceed 160 megawatt hours (MWh) per year. Customers on this plan are charged in block rates. Rates are as follows:

A2 Residential Tariff

Supply rate Usage rate
$1.0514 /day 29.3273 c/kWh

K2 Combined Use Tariff

Supply rate Usage Rate (First 20 units) Usage Rate (Next 1630 units)
$1.8553/day 30.6376c/kWh 28.8719c/kWh

Prices include GST and are accurate as of July, 2021.

Horizon Energy Prepaid Power

Residential energy customers on the Horizon Power network also have access to a Prepaid Power option. This product allows households to pre-purchase energy through the Horizon Power app and keep track of electricity usage. Plus, with the prepaid option, bill-payers can share power costs with others in the household or even among other households.

To be eligible for this product however, households will need to be on the A2 Residential Tariff, own an advanced meter, have access to the Horizon Power app and not have life support equipment in use at the property.

Horizon Power Business Electricity

Business electricity tariffs depend on what type of business you’re operating. There are four types of business electricity tariff. These are:

  • C2 Community Service Tariff: Includes Community clubs, youth groups, non-profit groups, fire/rescue groups;
  • D2 Charitable Accommodation Tariff: Emergency accommodation, homeless shelters, aged care and women hostels;
  • L2 Small Businesses: Businesses that use up to 50 MWh of electricity per annum;
  • L4 Medium/Large Businesses: Businesses that use more than 50 MWh of electricity per annum.

There are also special tariffs for government entities and a tailored option for Pilbara businesses that consume more than 1,200 MWh of power each year.

Horizon Power Solar

Customers must apply and receive approval from Horizon Power before they’re allowed to install a solar system. This is to allow for Horizon Power to ensure that the technical requirements of your solar installation can be met by your property and the network grid. Some areas of regional WA such as Broome, Denham and Exmouth, are currently unable to install new solar systems due to the network hitting capacity.

Regional WA’s energy network is made up of three interconnected networks and 32 small networks called microgrids. Because solar systems must be connected to an energy grid to feed-in excess electricity, there’s only so much electricity that a network can take. When a section of the network reaches capacity, unfortunately, Horizon Power must limit the number of households with access to the network for additional energy generation purposes.

If your solar application has been accepted by Horizon Power however, you should hear a response within 10 business days. Once you have a written approval, you’ll have three months to install your system. If you do not install your system during this time, your approval will become void and you’ll need to reapply.

Horizon Power customers with solar can also earn themselves 10c per kilowatt hour (kWh) for exporting their solar energy back into the grid during peak times (3pm-9pm) and 3c/kWh in off-peak times (9pm-3pm). This is awarded through the Distributed Energy Buyback Scheme (DEBS).
