Managed water from AGL Hydro reduced by 30% compared to FY19. The decrease is mainly due to a general reduction in water managed across facilities, including significant reductions at Dartmouth Power Station (down from 1,632 GL in FY19 to 885 GL in FY20), Eildon Power Station (down from 1,314 GL in FY19 to 774 GL in FY20), and Copeton Power Station (down from 214 GL in FY19 to 13 GL in FY20).
Managed water comprises non-consumptive use of water.
