Key points to note

  • Renewable energy contributed 79.8% of New Zealand’s electricity in the December quarter 2014. This brings the renewable energy share of electricity generation to 79.9% for the 2014 calendar year — this is the highest annual share of electricity generation from renewables since 1996.
  • Geothermal electricity generation contributed more electricity than gas generation in the December quarter — this is the third consecutive quarter this has happened. Geothermal generation for the 2014 calendar year was also higher than gas generation. This is the first time since 1975 that this has happened.
  • Electricity consumption in the December quarter 2014 was up by 2.7% from the December quarter 2013. This increase was driven by a large increase in the Agriculture, Forestry and Fishing sector (up by 25% over the same period) due to irrigation demand, and an increase in residential electricity demand by 2.9%. Electricity consumption for the 2014 calendar year at 39,201 GWh was up by 1.3% from 2013.
