Notes

1 Excludes generation used on-site for auxiliary services (e.g. lighting, coal grinders) and internal losses. Generation is prior to Transmission/Distribution losses.

2 Other renewable generation includes Wood, Biogas and Solar PV.

3 Includes unallocated onsite consumption and from Sept 2013 onwards estimated Solar PV consumption per sector.

R Data revised due to updated company returns.

 

Key points to note

  • Electricity demand was down 1.9 percent from the previous March quarter, driven by a 3.8 percent fall in industrial demand.
  • Renewable generation increased by 3.9 percent points from the March 2016 quarter. This increase came mostly from a 6 percent rise in hydro-generation over the same period, where there were high hydro storage levels and a plentiful supply of hydro-electricity in the March 2017 quarter.
  • Higher levels of hydro generation resulted in a 52 percent fall in coal generation and a 17 percent fall in gas generation from the March 2016 quarter.
