Meter Types

Remotely read smart meters transmit usage data daily making it easier for a retailer to bill customers based on their Actual (A) usage data, this means it’s unlikely we ever need to issue a catch-up or adjusted bill.

However as shown in the table above, not all meters are remotely read smart meters.

Most gas meters are manually read basic, some older electricity meters are too, and there are also a few manually read smart meters.

We can only know your Actual (A) usage when we have received actual data from your meter. In the months in-between we use Estimate (E) reads to calculate your bill. When your next Actual (A) bill is calculated, the previous Estimate (E) balance is taken into account so that in the end – you’ll have a correct account for your exact usage.

Example: Imagine the last series of monthly reads on your meter were 8100, 8200, 8300, 8400. That means you used 100 units every month for three months. Let’s imagine you pay $1 per unit. You should be billed for $100 each month. This equals $300 for all three months together. See the diagram below.

Even if an estimate is wrong, it gets adjusted on the next read. Imagine your third month’s read was overestimated incorrectly, and we used an estimate read (E) of 8350 (instead of 8300). You would have been billed like this: 100 units in month one, 150 units in month two , but only 50 units in month three. This still equals $300 for all three months together.

The previous examples assume you have a flat price per unit. However, what happens if your energy plan has step pricing or if there was a price change between the last two actual reads?

Example: Imagine the last series of monthly reads on your meter were 8100, 8150, 8200, 8400. That means you used 50 units in the first month, and 250 the two remaining months. Still a total of 300 units, but not evenly. Then imagine there was a price change, and you pay $1 per unit in month one, and $0.50 per unit in months two and three. You should be billed for 50 units at $1 = $50 plus 250 units at $0.50 = $125. A total of $175. See diagram below.

(E) means estimate, and (A) means actual.

This short video explains how your bill was calculated if it is based on an estimate.

GloBird’s My Account portal contains charts that plot estimates against actuals.

A "reference read" is a meter read that is not estimated by the retailer, it is usually provided by the independent distributor or the customer (self-read).

There are four important dates on your energy invoice:

The billing period will have two dates. Let's imagine your bill covers the period 1st June to the 30th of June, and the meter reads used for these two dates are both GloBird estimate reads.

For your reference GloBird will also display the two most recent reference reads. In this example, let's imagine there was an actual read from the distributor on the 15th April and again on the 15th of June.

In the past, we used to bill monthly monthly for electricity, but every two months for gas. This made budgeting difficult for customers, especially those who have both electricity and gas on one account.

For example, if you use $100 of electricity every month and $100 of gas every month, you received a bill like this:

To help smooth out the billing for the months when we don't receive an actual gas meter read from your local distributor, we will use an estimate instead. This means you will receive a bill that looks more like this:

As you can see the total cost is the same but means you will now receive, easier to manage bills.
