The Australian Energy Regulator (AER) monitors and reports on wholesale electricity markets. As part of this role, we report on events that result in wholesale electricity spot prices exceeding $5000 per megawatt hour (MWh).
Most end-customers are not directly exposed to wholesale electricity prices. Energy retailers are the main purchasers in the wholesale electricity market. Retailers bundle electricity with network services for sale to their residential, commercial and industrial customers. Generators and retailers can manage their exposure to price variations in the wholesale market by entering hedge contracts that lock in firm prices for the electricity they intend to produce or buy.
On Friday 10 February the spot price in New South Wales and Queensland exceeded the $5000/MWh reporting threshold on four occasions. Spot prices in New South Wales reached $12 915/MWh at 5:00pm, $13 967/MWh at 5:30pm and $14 000/MWh at 6:00pm. In Queensland the spot price reached $12 222/MWh at 5:00pm.
On Saturday 11 February the spot price exceeded the $5000/MWh reporting threshold on three occasions in Queensland reaching $7628/MWh at 4.30pm, $8569/MWh at 5:00pm and $8372/MWh at 5:30pm.
On Sunday 12 February the spot price in Queensland exceeded the $5000/MWh threshold on one occasion reaching $9005/MWh at 5:30pm.
We expect to publish the report into these high prices within 40 business days, by 10 April 2017, on the AER’s website.
