Main highlights for this quarter

  • National electricity demand rose 6 per cent 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 per cent, down from 81 per cent 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 per cent. 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 per cent on the previous year.
  • Prices for regular petrol rose 6 per cent from last quarter, to be up 16 per cent from June 2020. This reflects strong growth in international crude prices (up 17 per cent this quarter). Importer margins fell by 32 per cent compared to June 2020, and fell by 16 per cent compared to June 2019.
  • The ETS component paid on regular petrol has increased 54 per cent compared to last year.
