How is my ‘usual usage’ calculated, and has this changed from last year’s program?

We have not changed the baseline calculation from last year’s program. 

From the 60 days prior to each event:

  1. We look for the 10 hottest days in that period. Out of those 10 days, we pick the 4 days when you used the most energy. We take the average usage across the 4 days. 
  2. We know that weather conditions on the event day can be different from previous days. Extreme temperature, haze and cloud cover will affect a household’s energy patterns. 
    So when the event is over, we go back and look at the how the energy usage for your postcode area changed during the event. These wider trends are used to adjust your average usage to produce your unique baseline, e.g. if non GoodGrid households in the postcode are generally producing less solar generation, or generally using more electricity due to it being an extremely hot day, then we adjust the baseline to reflect this. 

Why is solar generation included in my baseline calculation?

Your smart meter is a net meter, that is, it can’t tell how much solar energy you are generating, only how much energy you are using from, or providing to, the grid. So it’s not possible for AusNet Services to separate your solar output from your usage (as only you have access to your solar inverter). 

We also understand that you can’t control how your solar panels perform during a particular GoodGrid event. We do our best to adjust for cloudy / sunny conditions during an event, by looking at the energy usage patterns of other solar homes in your local area. We then use these wider trends to adjust your baseline to suit. 

How has the bushfire smoke affected my solar generation?

If you are a solar customer, you will experience a decrease in solar output during hazy days as a result of bushfire smoke. You may also find your solar efficiency has generally decreased even outside of those heavy haze days. This could be due to a layer of ash on your solar panels due to the bushfire smoke – the ash and soot can travel thousands of kilometres before settling. To improve your solar panel performance you may wish to consider cleaning your panels as per your manufacturer’s instructions.

If you want to know more about how solar generation is treated as part of GoodGrid, see above. 

What is the GoodGrid Program?

GoodGrid is a Program developed by AusNet Services that seeks to educate and engage residential and small business customers to manage their energy use during high demand, or ‘peak’ periods. RACV are supporting AusNet Services to offer this program to their customers in selected postcodes in key areas. By participating, you can help ensure that grid continues to work reliably during peaks – and cut your power bills too.

This summer, the Program is open to 1,000 customers within ten postcode areas serviced by our electricity network.

Participating customers in eligible areas can earn incentives for cutting energy use during short high demand periods, known as ‘GoodGrid Events’. 

The GoodGrid Program will run from 1 December to 31 March. Last year we ran 10 events and we expect to run a similar number of events this summer. GoodGrid Events will be four hours long, usually in the afternoon and early evening.

We will give participants tips about how they can cut their energy use during very high demand days.

How do the prize draws work?

If you register by 17 November 2019, you’ll be in the running to win a $1000 RACV Resorts Voucher. The early bird prize draw will happen on 18 Nov 2019

All participants who register by 15 Jan 2020 will be entered into a prize draw for an additional $1000 RACV resorts voucher. Unfortunately the winner from the first prize cannot win again. This draw will happen on 16 Jan 2020.

How does the Program work?

AusNet Services will alert registered participants before an upcoming GoodGrid Event. If a participant reduces their energy usage during the event to a level below what they have used on similar days previously, AusNet Services will pay them an incentive of $10 – no matter how big or small that reduction is.

In addition, each participant will be sent a survey via email before each event. For each completed event survey, AusNet Services will reward $5.

GoodGrid participants are not obliged to reduce power use during peak events. But we’ll reward them if they do.

What do GoodGrid participants have to do?

Not very much! Just make a few small and easy changes to the way you use electricity during a GoodGrid Event. This could be managing the way you use electrical appliances, or even planning a trip to the shops or movies during the Event.

You can check your eligibility using the online eligibility and registration form

Note: We take safety seriously and, for their own welfare, customers deemed as ‘vulnerable’ are not eligible for this progam. This means a customer with life support equipment, or households where there are people with health risks that could be impacted by reducing consumption on hot days. Additionally customers who are part of an embedded network are not eligible to participate.

How do we work out whether a customer has reduced their usage?

In a GoodGrid Event, we ask you to reduce your electricity usage below what it would otherwise have been during the event period. We call this normal usage level your baseline.

Your baseline will differ slightly between GoodGrid Events, as conditions (and hence your normal usage) on each separate GoodGrid Event will be different.

To calculate your baseline for a given GoodGrid Event, we use a formula which draws on a range of inputs:

  • Your energy usage data during the GoodGrid Event period, on up to ten days, which had similar weather and similar usage
  • The kind of day the GoodGrid Event occurred on – e.g. a weekday or weekend, and in or outside the school holidays
  • Broader customer consumption patterns across your area during the GoodGrid Event


If you own solar panels, your solar generation is included when calculating your baseline, and you are rewarded for increased exported energy during the event period.

Based on participant’s feedback last summer, we’ll now be providing a more detailed assessment of your electricity usage for each GoodGrid Event, compared to your normal usage levels.

I recently moved into a new house. Can I sign up for GoodGrid?

You need to have been living at your current property for at least 60 days to register for GoodGrid. This is because we need some history to be able to work out what your normal electricity use is.

I am moving house in Jan/Feb/March. Can I still stay in the program, and will I still be eligible for the prize draw?

Unfortunately, if you move house we won’t be able to calculate your baseline power consumption and assess whether you have reduced your energy use or not. So in this situation, you will not be able to remain on the GoodGrid program. We will, however, pay you any reward money you have previously earned at the end of the summer.

If you were in the program on 15 January, you will still be in the prize draw.

What is a GoodGrid event?

A GoodGrid Event called when there is expected to be high power consumption in your area. By reducing your energy usage during these times, typically four hours, in the late afternoon and/or early evening on hot summer days – the community can help to ensure the lights stay on and over time, reduce investment in the network, reducing costs for everyone.

When will a GoodGrid event be declared?

A GoodGrid Event may be declared on a day when we expect the community’s energy needs to put strain on local poles and wires - typically hot days over summer, in the afternoon and early evening, e.g. 4 - 8pm when the grid is experiencing the most demand. By getting involved, GoodGrid Participants will be able to help keep the lights on within your community, as well as earn incentives.

How many Events will there be?

Last summer (2018/19) we called 10 GoodGrid Events and this year we expect to call between 5 to 10 Events. As always, participation is voluntary and the reward is based on reducing your usage compared to your normal usage on a comparable day.

How can a participant track their usage?

We encourage customers to sign up to AusNet Services’ myHomeEnergy (mHE) portal. mHE allows customers to monitor, budget and assess their individual electricity consumption data.

How will GoodGrid Participants be notified?

We aim to send communications to GoodGrid Participants the day before an event day. We will also send another communication on the day in the hours before the event. We may also send communications during or after the event with tips or to advise participants that an event has ended.

A GoodGrid Participant will be notified by email and SMS. The communications will be sent to the details provided when a GoodGrid Participant signed up.

Why GoodGrid?

  • The GoodGrid Program seeks to take a proactive approach to inform and work with participants to reduce your energy use, thus contributing to local reliability and also reducing your bill.
  • Residential demand management is part of the AusNet Services summer response program.
  • We are trialling new ways of working with customers to reduce network strain and the possibility of power outages.
  • By reducing overall peak demand, we are also reducing the need for network investment to manage these few high consumption days. In the longer term, this will reduce costs for all of our customers.

What are the benefits to participants?

  • Participants will be empowered with tips that may assist them to reduce their energy consumption.
  • Lower energy use can lead to lower bills.
  • Customers who participate in the program will be eligible to receive an incentive of $15 per event 
  • Participants will have two prize draw opportunities (early bird and midway through the program) to win a $1000 RACV resorts voucher. Unfortunately the winner from the first prize cannot win again
  • The Program will contribute to improved supply reliability for them and their community – “helping keep the lights on”.

What are the benefits to AusNet Services?

Reducing demand on local network infrastructure means we will need to upgrade the network less, reducing costs for everyone. It will also help to keep the lights on ensuring good service for the community – including vulnerable households, hospitals and schools.
