To find out more about smart meters, meter data and your electricity bill information.
To find out more about your electricity plan, what tariffs are and why they’re important.

If you need help finding where each of these pieces of information are on your bills, you can check out our guide with annotated examples here.

SunSPOT uses the information you provide to tailor your estimate to your property. The more detail you can add, the more accurate your estimate will be.

If you want to go straight to requesting smart meter data in NEM12 format from your distribution network service provider (DNSP), click here.

⚠️ Currently, SunSPOT’s calculations do not account for scenarios where a battery is already installed and operational on a property. Any estimates calculated using meter data from a property with an existing battery will not be accurate.

  • If you have an interval or smart meter, you can request 12 months of your electricity usage data from your Distributed Network Service Provider (DNSP) and upload it to SunSPOT. This will produce the most accurate estimates possible.

    At this stage, SunSPOT only accepts meter data in CSV files in NEM12 format which your DNSP will send to you upon request. SunSPOT cannot accept data in other formats from energy retailers or other apps.

  • SunSPOT has some data requirements that must be met before uploading to avoid errors. This includes allowed date ranges and the requirement for NEM12 formatted data only. We update the allowed date ranges every few months to add more allowed dates, so to check the current requirements click here.

    The page linked above also has guidelines around what data to request if you have recently installed solar or made a big change to the property that changes how you use electricity.

    If your data does not meet the requirements, try a different method for sharing your usage information, like adding your usage manually. If you already have solar and are looking at upgrading or replacing the system, you may need to try a different SunSPOT pathway by going back to the home page and selecting a different starting option for now.

  • If any of the following are true for your property, it’s likely that you do have a smart or interval meter:

    ✔️ You had solar installed in the past 3 years

    ✔️ You are billed different rates for different times/days (this is ‘time of use’ or TOU billing)

    ✔️ Your property is new (built after 2017)

    ✔️ Your property is located in Victoria

    If someone comes to read your meter in person, you probably don’t have a smart meter. However, you may still have an interval meter: if you have time of use billing, then it’s likely that you have an interval meter.

    You can request and upload meter data to SunSPOT if you have either a smart meter or an interval meter.

  • Your Distributed Network Service Provider (DNSP) is different to your electricity retailer. You can find your DNSP named under “Faults and Emergencies” on your electricity bill, or by searching the Australian Energy Regulator’s Who is your distributor? page.

    The DNSP is the organisation that owns and controls the physical infrastructure used to distribute electricity (like power poles and wires).

  • We have a whole section on this website dedicated to helping you find and access your smart meter data here.

    You’ll need to know your DNSP and your NMI number, and you can find both on your most recent electricity bill.

We update the allowed date ranges every few months to add more allowed dates, so to check the current requirements click here.

  • The NEM12 format is designed by the Australian Energy Market Operator (AEMO) and is the format required by the National Electricity Rules (NER) for retailers and DNSPs to provide detailed meter data to customers. This means that all data in NEM12 format has the same structure and quality requirements by law.

    Because electricity data can be very complex and can be structured in lots of different ways, using this regulated format means that SunSPOT will always know how to read your NEM12 meter data. This helps validate your data and prevent errors in the calculation that could occur with tiny changes to the data format.

  • In some cases you may not be able to upload meter data CSV files from an Android device in a Chrome browser. Unfortunately, this is caused by an issue within the Chrome browser itself and some versions of Android operating systems.

    What you can do is try a different browser (e.g. Safari or Firefox), or a different device (e.g. a laptop or desktop computer). If you’re still running into issues with uploading data, please get in touch and we’ll try our best to help.

  • For residential users, adding information from multiple bills (up to a full year) helps SunSPOT understand how your electricity usage changes across the seasons.

    Commercial users can add information from one recent bill. To get the most accurate estimate, commercial users should upload 12 months of real meter data in NEM12 format.

    Check out this page for help understanding your bill, including a guide to finding the information SunSPOT needs.

Electricity plan bill icon Electricity plan

Adding your own electricity tariffs or rates allows SunSPOT to calculate a more tailored estimate of your potential bill and savings with solar.

Your electricity plan, or tariff, is the rate you are charged by your retailer for providing electricity. There are a number of different common tariff types, with Flat or Single Rate and Time of Use being the most common for residential properties. Commercial or small business properties may also have a Demand Charge as part of their electricity plan.

A feed-in tariff (FiT) is commonly offered to retail customers with a solar system, and is the rate that the customer is credited for any solar energy that isn’t used on-site and is exported to the grid. FiTs are not guaranteed by every retailer.

  • Some plans include feed-in tariffs that vary depending on how much solar has been exported already in a day. Most variable volume feed-in tariffs apply a high initial rate up to a certain amount of exported solar, and after this threshold is met a lower rate is applied.

    For example, if your solar system exported 10kWh in one day and you had a variable volume feed in tariff that credited 10c/kWh for the first 3kWh and then 5c/kWh for the rest, you would receive ($0.10 x 3 + $0.05 x 7) = $0.65.

  • Some feed-in tariff (FiT) rates vary by the time of day, meaning that different rates are applied to exported solar depending on when it was exported.

    For example, a time of use FiT might apply a rate of 3c/kWh for all solar exported between 8am - 3pm each day, and 10c/kWh for export between 3pm - 5pm.
