GOODGRID CPD – FOR CPD CUSTOMERS
Business customers, who use more than 160 MWh per year, can reduce their electricity bill limiting their electricity use on peak days with our GoodGrid CPD program.

  • How does GoodGrid CPD work? 

    Each summer, between 01 December and 31 March, AusNet Services nominates five Critical Peak Demand (CPD) days. These days coincide with extreme temperatures and consecutive days of hot weather. During each of these CPD days there is a CPD window between 3 pm and 7 pm AEDT. If you can reduce electricity usage during this window on a nominated CPD day, you can minimise the CPD charge on your electricity bill.

    To register for SMS notifications about CPD days, send your national meter identifier (NMI) reference number(s) by SMS to 0418 176 593. If you’ve already registered for SMS notifications, you don’t need to register again.

  • What is a CPD charge?

    The CPD charge is a monthly charge included in the network component of your electricity bill. The CPD charge is calculated by multiplying a fixed price (the CPD price) by the average of your peak electricity demand during the CPD window on each of the five nominated CPD days. Your average peak electricity demand is measured in kilovolt-ampere (kVA). The example below shows how we calculate your CPD charge.

     
    We recalculate the average peak electricity demand component of your CPD charge annually. By lowering your peak demand during each CPD window, you are likely to reduce your average peak electricity demand, and therefore reduce the amount of CPD charge you must pay each month for the next 12 months.
  • How can my business reduce its electricity demand?

    Your business can reduce electricity use in several different ways. For example, you could:

    • switch to another form of electricity supply like a generator or battery storage
    • shift your electricity use some that you are using more electricity outside the CPD window
    • scale back or shut down production during the CPD window

    CASE STUDY

    This example shows how participating in the GoodGrid CPD program can reduce electricity costs for a business.

    In this example, the hypothetical CPD charge is $5 per kVA per month. Business customers ‘Amanda’ and ‘Boris’ each have an average maximum demand of 500 kVA between 3 pm and 7 pm in summer.

    Amanda signs up to the GoodGrid CPD program. She is notified about upcoming CPD days and decides to switch part of her load to a generator during each CPD window. By using a generator, Amanda reduces her peak demand during each CPD window from 500 kVA to 300 kVA.

    Boris uses electricity as he normally would and so Boris’s peak demand during each CPD window remains 500 kVA.

    After the GoodGrid CPD Program ends, AusNet Services recalculates Amanda’s average peak energy demand. For the next 12 months, Amanda’s CPD charge is calculated using an average peak demand of 300 kVA. Her CPD charge will be $5 x 300 kVA = $1,500. This CPD charge will be one component of her total network charge.

    The network component of Amanda’s electricity bill is now $1,000 lower than it would have been if she had not actively reduced her peak demand during the CPD windows.
    However, because Boris’s average peak demand remains the same, his CPD charge remains unchanged. His charge will be $5 x 500 kVA = $2,500.

  • Who can participate?

    If your business uses more than 160 MWh of electricity per year and you are assigned to a CPD tariff, you are already part of the program. Almost all our large business customers are already on a CPD tariff, but to confirm, please contact us on 1300 451 331.

  • How will I be notified of a CPD day?
    If you register your mobile phone number with the GoodGrid CPD program you will receive SMS notifications about CPD days. You will receive notifications about potential CPD days up to 7 days before an event and you will receive a notification by 2:00 pm AEDT on the day before a declared CPD day. CPD days also get posted on AusNet Services’ website www.goodgrid.ausnetservices.com.au
  • Will I see the reduction on my bill? 
    The CPD charge forms a part of the total network charge shown on the bill issued by your retailer. If your business participates in the GoodGrid CPD Program, you will not see an explicit reference to the reduction in your CPD charge. However, your CPD charge will be lower than it otherwise would have been if you do not participate. For more information visit our website at www.goodgrid.ausnetservices.com.au.
