The main highlights for this quarter are:

  • Renewable sources accounted for 80 per cent of electricity generation this quarter.
  • Coal fired generation was 138 per cent higher than in March 2018.
  • Hydro generation was down 1 per cent from March 2018, with lake levels being below the historical average for the entire quarter.
  • Overall gas supply was 12 per cent below March 2018 levels, largely as a result of continued outages at Pohokura.
  • Daily average wholesale energy prices peaked at $276.79/MWh and averaged around $150/MWh across the quarter.
  • Petrol prices are almost back to the same levels as March 2018, however diesel remains elevated.

Electricity statistics

Revisions to previously published data:

  • The Ministry has introduced a new code-based system for producing electricity generation statistics (covering generation, fuel use, and capacity), resulting in minor revisions to previously published data.
  • Several smaller retailers have been added to the Ministry’s electricity sales data collection following a review of data coverage. Sales data is used to produce electricity consumption, cost, and installation control point (ICP) statistics.  The inclusion of these retailers has led to revisions in previously published statistics – most notably the Residential ICP count.

Coal statistics

Revisions to previously published data:

  • Coal imports for the December quarter 2018 have been revised following the publication of data on imports by Stats NZ.  The Ministry estimates coal imports using several sources, and the release of this additional data has led to improvements in the estimation process.
