The installation of battery components for the 50MW/64.5MWh expansion of the Hornsdale Power Reserve is now complete, and site works to finalise the connection and testing of the expansion have commenced. This requires an outage of the existing battery, which commenced today. The outage was agreed in consultation with South Australian Government, AEMO and ElectraNet, and has been carefully timed for a period of anticipated average demand with no other major network outages.

It is anticipated the works will be completed later this week, at which time the existing 100MW will be back on-line to provide its regular services. Commissioning and testing works will then commence for the 50MW expansion and it is anticipated commercial operation of the expansion will commence before mid-year.
