Main highlights for this quarter

  • The renewable share of electricity generation for the quarter was 87.5%. This was the highest March quarter renewable share since 1996.
  • Hydro generation was 7.4% higher than in the March 2022 quarter, largely due to high rainfall in the North Island including the Auckland anniversary weekend floods and Cyclone Gabrielle. This is despite lower than usual inflows at several South Island hydro catchments.
  • Coal-based generation was down 61.1% and gas-based generation was down 17.1% when compared to the previous March quarter. Coal imports also fell 73% over the same period.
  • Industrial electricity consumption was down 4.1% from the March quarter 2022. This was led by a drop in wood production due to the disruptions and repairs following Cyclone Gabrielle. Overall electricity consumption was down 1% over this time.
