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.
