Additional information

AGL has signed four innovative battery derivative agreements with Maoneng Group, which will provide security of pricing to benefit customers during peak periods. The deal will see Maoneng develop four large-scale batteries, each 50 MW/100 MWh in capacity in New South Wales. Under the contract, AGL has the ability to call on capacity as required from the Maoneng batteries at a fixed price for 15 years, thereby locking in a price on the cost of electricity for that period.
