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

  • Hydro generation was 2.2% lower compared to the June 2016 quarter. Lower rainfall led to well below average inflows to South Island hydro lakes and a reduction in hydro generation. Higher rainfall in the North Island resulted in a significant increase in North Island hydro generation, which went some way to cover the lower output from the South Island.
  • Gas-fired generation increased to meet demand, contributing to the renewable share of electricity generation falling to its lowest level in two years, at 79.5%.
  • Electricity demand from the residential sector returned to 2015 levels. Residential demand was up 4.3% from the June 2016 quarter, when warmer than usual temperatures lowered household electricity use.
  • Electricity demand by the agricultural sector was down 17% from the June 2016 quarter.
