    The newly connected Broken Hill battery has helped NSW beat a short-lived record for battery charging and discharging, breaking the habit of a lifetime – in its case a whole week – to feed back into the grid in the morning peak rather than the evening peak.

    The 50 MW/100 MWh Broken Hill battery, owned by coal giant AGL, has suffered lengthy delays in its connection process but is now finally working through its final commissioning process.

    In the past week it has been regular as clock work in its charging and discharging patterns – loading up in the early afternoon where rooftop solar has pushed prices down, and then discharging at 6.30pm or 7pm into the evening peak, when the demand and prices are higher.
