Water withdrawal by source
There was a small increase in the use of surface water at AGL Loy Yang and AGL Macquarie (up 4%). Groundwater use increased 18% across AGL Energy, mainly due to increased withdrawal at AGL Loy Yang. Rainwater usage remained consistent with FY20.
Municipal water declined 16%, mainly due to significant decreases observed across AGL Energy's smaller offices, which were shut down for periods of FY21 due to COVID-19 restrictions. Waste water withdrawal is reported by Somerton Power Station only, with the 35% decline in withdrawal being directly associated with reduced Somerton Power Station activity.
