Western Australia Price Index

On 23rd May 2019, Energy Action commenced publication of the Western Australian Price Index. This is the first index of its kind to bring price transparency to the Western Australian electricity market for commercial and industrial customers.

The WA EAPI tracks the market rate of commodity electricity exclusive of capacity costs. It is created from the lowest cost offers submitted by retailers via the AEX for loads of 1, 2 or 3 years duration.

Commentary November - December 2020


The Western Australia Price index shows the price for retail electricity supply taken from Energy Action’s recent auction results. The index continues to trade sideways at just below 5c/KWh. The outlook for Western Australia remains stable with limited scope for additional price volatility. This is due to the unique features of the Western Australia electricity market which includes a reserve capacity mechanism to ensure adequate generations is available at all times.

Western Australia continues to push ahead with promoting new technologies around distributed generation. This brings greater price certainty to the Western Australia market, providing consumers with greater reliability and price certainty while allowing increased control over how future energy needs will be met. Pricing in Western Australia is expected to remain around current levels with limited short-term price volatility. We recommend retail customers act now to test current pricing via our auction portal. This approach provides our customers with greater competitive pressure from WA energy retailers and overcomes the limited price discovery within the Western Australia electricity market.
