How are adjustments to my bill calculated? 📄

Powertracer enables you to buy and sell energy at different prices to those set by your retailer (Retailer Default Trades). So at the end of each month, Powertracer calculates the difference between these prices, for the volume of energy bought and sold, and creates an adjustment to your bill.

Let’s look at a couple of scenarios:

If you set up a trade rule to buy energy for less than what the retailer charges you, and Powertracer successfully matches your demand with available energy, this will result in a credit adjustment to your bill.

Based on the retailer prices below for a property in NSW, the price to buy energy is 16.075c/kWh:

If a peer-to-peer trade rule was created in Powertracer to buy energy for 10c/kWh as follows:

there is a savings of 6.075c for each kWh bought. So if 100kWh of energy was bought during the month according to this trade rule, then there will be a 6.075 * 100 = $6.08 credit adjustment on the bill.

In the above example the buying party made a 6.075c/kWh saving, but was the selling party also better off financially?

As the selling party sold energy for 10c/kWh, then it’s likely they sold for more than the feed-in tariff, but, in this example, it depends what time of the day the energy was sold. This is due to the retailer feed-in tariff being a Time Of Use tariff:

So based on the tariff timings above, if the selling party sold energy before 4pm or after 9pm they sold at a better rate (between 4pm and 9pm the feed-in rate is the same at 10c/kWh, so they were neither better or worse off).

Powertracer automatically calculates the price differences for all traded energy, every half an hour of every day, and totals these up as one value adjustment for your monthly bill. Price differences for traded energy can result from three types of trades: Contracted, Peer-to-Peer & Community Trades. Any Retailer Default trades seen in Powertracer are at the retailer rates, and therefore are not included in any adjustment calculation.
