What is an ARO and how does it work?
An ARO sets the maximum average spot price payable in any quarter, known as the strike price. It’s similar to a Cap, but the main difference is that you can set the price limit yourself, rather than the fixed price of 30c/kWh – so you have more control over your spend.
If the average price comes out higher than the strike price, you’ll only pay the strike price – and if the average is lower than the strike price, you’ll pay the lower price.
Calculated in half-hour intervals, an ARO lasts for a quarter, and can be contracted up to eight calendar quarters in advance.

How do I secure an ARO?
Based on custom recommendations from Flow Power, you can choose your price limit on your ARO.
You pay for a small premium when the ARO is activated, but it gives you a level of certainty that’s worth it.

ARO in action
In an example from Q1 of CY18, the fixed rate price from the market is $104 /MWh. An ARO can be purchased at a strike price slightly higher than this – around $124.80 /MWh (120% of the market price).

You’ll never pay more than the strike price – but if spot prices are lower than a comparable fixed rate price, you benefit from the lower spot prices.

Where do I find information on my spend?
When receiving your power bill each month, there will be a section featuring your ARO charges for the quarter.
