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

  • Higher rainfall over the December quarter saw increased hydroelectric generation during the quarter, up 7.1 per cent over the previous December quarter.
  • Lower irrigation demand saw overall electricity demand decrease by 3.3 per cent compared to the previous December quarter.
  • Reduced generation from coal- and gas-fired sources saw New Zealand achieve renewable electricity generation of 88.1 per cent during the December quarter.
  • Overall generation levels were 2.8 per cent lower than the same period last year.

Key points to note

  • Two month shutdown of the Maari offshore platform reduced crude oil production by 24 per cent and contributed to a 40 per cent reduction in crude oil exports when compared to the December quarter 2015.
  • Consumption of diesel was up 5 per cent while domestic production of diesel fuel was down 5 per cent. An 81 per cent increase in imports of diesel fuel bridged the gap in supply.
  • Aviation fuel production increased 6 per cent, reflecting growing demand from more long-haul flights into Auckland from Asia and the United States.
