New Zealand Energy Quarterly – September 2023

The New Zealand Energy Quarterly provides quarterly data and analysis on energy supply, demand, prices and associated greenhouse gas emissions. This edition was released in December 2023.

Main highlights for this quarter

  • Electricity generation from wind reached a record high of 920 GWh for the quarter, an increase of 19.1% compared to the same period last year. This was driven by a combination of increased wind generation capacity and windy conditions for the quarter.
  • The renewable share of electricity generation for the quarter was 84.1%. This is a 5.5 percentage point decrease on the September 2022 quarter.
  • Hydro generation was 10.6% lower than in in the September 2022 quarter, largely due to low rainfall and planned outages at hydroelectric plants.
  • Coal-based generation increased by 90% and gas-based generation increased by 47% when compared to the previous September quarter to meet demand.
  • Greenhouse gas emissions from electricity generation increased by 64.4% on the September 2022 quarter. This was driven by the increase in use of coal and gas for generation.
