Energy data file published
Energy Minister Trevor Mallard today released the January 2005 edition of the Energy Data File, containing comprehensive
statistics including energy supply and demand data.
This report is prepared by the Ministry of Economic Development and shows that:
Total primary energy supply in the year to September 2004 was relatively unchanged at about 763 petajoules. This
includes imports of oil and oil products. Total (domestic) energy consumption for the same period increased by 2.2 per
cent to 508 petajoules, due to continued increase in domestic transport energy use as outlined below.
Total (premium and regular) petrol consumption increased by 4.4 per cent while diesel use increased by 3.3 per cent in
the year to September 2004. Total oil consumption increased by 2.7 per cent due to higher aviation fuel consumption but
was offset by decline in fuel oil consumption.
Coal production in the year to September 2004 decreased by 4 per cent on the previous year to about 5.0 million tonnes.
Total utilisation, including exports mainly for steel production and imports for mainly generation, increased by 9 per
cent to 5.9 million tonnes during the same period.
Total electricity generation for September year 2004 is estimated at 41,500 GWh and is 4.2 per cent higher than for
September year 2003; significantly higher hydro and coal generation was offset by lower gas based generation for the
entire period.
New Zealand gas production in the year to September 2004 declined by 22 per cent to about 150 PJ, with 64 per cent
coming from the Maui field. About 31 per cent was used for petrochemical production, 41 per cent for electricity
generation and 28 per cent for industrial, commercial and domestic purposes. Gas used for generation (including for
co-generation) in the year to September 2004 was 60 PJ, about 33 per cent lower than for the previous year following
reduced gas availability from the Maui field and due to rationalisation of the use of available gas by generators.
