New Zealand Energy Quarterly – June 2021

The New Zealand Energy Quarterly provides quarterly data and analysis on energy supply, demand, prices and associated greenhouse gas emissions. This edition was released 10 September 2021.

Main highlights for this quarter

  • National electricity demand rose 6% from the June quarter 2020, but there was no change compared to pre-COVID (June quarter 2019).
  • The renewable share of electricity generation was 74.9%, down from 81% this time last year. This was the lowest share since the 2013 June quarter.
  • Reflecting ongoing poor hydro conditions, hydro generation was down 5.3%. While lake inflows increased in May, lake storage remained well below historical averages.
  • Coal imports were the highest on record as electricity generation from coal more than tripled, compared to June 2020. This was the highest amount generated from coal since June 2008.
  • Residential electricity costs increased 2.6% on the previous year.
  • Prices for regular petrol rose 6% from last quarter, to be up 16% from June 2020. This reflects strong growth in international crude prices (up 17% this quarter). Importer margins fell by 32% compared to June 2020, and fell by 16% compared to June 2019.
  • The ETS component paid on regular petrol has increased 54% compared to last year.
