Electricity generation decreased 3.2 per cent in the September 2001 quarter compared with the June 2001 quarter, after adjusting for seasonal variations, according to Statistics New Zealand.

Thermal generation was 60.4 per cent higher in the September 2001 quarter than in the same quarter last year. In August 2001, thermal electricity generation exceeded hydro generation for the first time since the months of June and July 1992.

In the year ended September 2001, total electricity generation was 35,000 gigawatt hours, a rise of 2.4 per cent. Although the September quarter is generally the high point of the annual demand for electricity, generation in the September 2001 quarter was 0.4 per cent lower than in the September 2000 quarter.
