Key points to note

  • Renewable energy contributed 76.9% of New Zealand’s electricity in the March quarter 2015, 2.9 percentage points lower than the previous March quarter. Drops in Hydro, wind and gas generation were balanced by large increases in geothermal generation and coal generation. Over the four quarters ended March 2015 the share of electricity generated from renewables was 79.3%.
  • Geothermal electricity generation during the March quarter 2015 was up by 13.6% from the previous March quarter. This is the second highest quarterly geothermal generation on record (the highest occurred in September 2014)
  • Electricity consumption in the March quarter 2015 was up by 0.7% from the previous March quarter. Although demand overall was only marginally higher than in the previous March quarter, there was a large increase in electricity demand for the Agriculture, Forestry and Fishing sector (up 20.6%) and a modest increase in electricity demand for the Commercial sector (up 2.6%).  These increases were balanced by demand drops in Industrial (down by 2.4%) and Residential (down by 3.0%).
  • The large increase in electricity demand for the Agriculture, Forestry and Fishing Sector was related to increased irrigation demand as a result of very dry soil moisture conditions in Canterbury and other regions*.

R Data revised due to updated company returns

 

Key points to note

  • Production of Oil in the March quarter 2015 was down by 15.0% from the previous March quarter. The major cause of this drop in production was a shutdown at the Tui oil field in March to commission a new well (Pateke 4H**) which started production in early April.
  • Crude oil imports in the March quarter 2015 were up 32.1% from the previous March quarter, and imports of oil products were down by 11.8% over the same period.
  • Diesel demand during the March quarter 2015 was up 3.5% from the previous March quarter. Petrol demand in the March quarter 2015 was 4.6% higher than in March quarter 2014.
  • These demand increases coincide with some significant retail price reductions for these products — the average retail price for regular petrol in the March quarter 2015 was 15.3% lower than in the previous March quarter, and the average diesel price over the same period was 24.8% lower. The international price of Dubai Crude oil in the March quarter 2015 was US $52.4 per barrel, compared with US $104.6 per barrel in the March quarter 2014.

† Dubai Crude is a similar grade of Crude oil to many of the crudes that commonly imported for refining in NZ.

Notes

R Data revised due to updated company returns

 

Key points to note

  • Gross gas production during the March quarter 2015 was 4.2% down from the previous March quarter. This was largely as a result of reduced demand for gas during the March quarter 2015.
  • The amount of LPG extracted from natural gas during the March quarter 2015 was 11.0% higher than in the previous March quarter.
  • Net gas production (the amount produced after reinjection, LPG extraction, flaring and losses and own use) during the March quarter 2015 was down by 1.0% from the previous March quarter.
