Main highlights for this quarter

  • Renewable share of electricity generation this quarter was 90.3%. This is a 4.4 percentage point decrease on the December quarter last year.
  • The Harapaki Wind Farm and the Kaitaia solar farm began operation this quarter, contributing to this increase in capacity for renewable energy.
  • Electricity generation from wind reached a record high of 977 GWh for the quarter, an increase of 32.9% compared to the same period last year. This was driven by increased wind generation capacity.
  • Hydro generation was 12% lower than in the December 2022 quarter, largely due to low rainfall. This resulted in an increase in coal and gas use to meet demand.
  • Coal-based generation increased by 219.3% and gas-based generation increased by 50.9% when compared to the previous December quarter. Coal and gas-based generation made up 3.5% and 6.1% of total generation respectively.
  • Provisional greenhouse gas emissions from electricity generation increased by 93% on the December 2022 quarter, driven by the increase in use of coal and natural gas for generation.
  • International aviation fuel use is up 51% on the December 2022 quarter. This signals continued recovery from a drop in consumption caused by travel restrictions in response to the COVID-19 pandemic.
