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

  • Both total electricity consumption and per-user electricity consumption fell over all measured consumer sectors compared to the same quarter last year.
  • The largest fall in electricity consumption occurred within the residential sector, whose consumption decreased 4.5 per cent compared to last year.
  • The largest quarterly per-user decline occurred within the industrial sector, whose average electricity consumption decreased 5.6 per cent compared to last year.
  • Households spent, on average, 2.8 per cent less on electricity this quarter than in September 2015.
  • Falling electricity demand led to decreased coal and gas-based electricity generation, producing the second lowest September quarterly CO2 emissions on record.
  • 86.1 per cent of New Zealand’s September 2016 electricity generation was derived from renewable energy sources.

R Data revised

 

Key points to note

  • Within liquid fuels, a strong increase in the transport sector’s fuel consumption in September 2016 quarter was met through increased petroleum-product imports rather than increased refinery-based production.
  • New Zealand refined output fell 2.9 % in the September 2016 quarter.
  • Indigenous crude oil production fell 17.5% in the September 2016 quarter.
  • Crude oil exports increased 2.0%, with the difference between increased exports and falling domestic production derived from reducing the volume of crude oil stocks-on-hand.

Notes

R Data revised

 

Key points to note

  • Gas net production increased 5.4 per cent compared to the same quarter last year. The increased indigenous gas production was consumed in non-energy use (up 18.0 percent) and Chemical industry consumption (up 15.9 per cent).

Notes

R Data revised

 

Key points to note

  • Coal production continues its slow decline - 2016 production was the lowest September quarterly production in 18 years
  • Bituminous coal exports increased 79.0% through a combination of 11.7 per cent more coal extraction and a 10.4 per cent decrease in the volume of stocks on hand, with producers running down their coal stockpiles.
  • Domestic coal consumption increases within the industrial sector were offset by declines within the Agriculture/ Forestry/ Fishing sectors, and coal-based electricity generation, resulting in an overall 4.5 per cent decline in domestic coal consumption.
