<strong>Energy</strong> facts<br />

Total New Zealand grid-connected electricity generation<br />

in the June 2008 year was 39,493 gigawatt hours. A<br />

further 3,000 (approximate) gigawatt hours of generation<br />

is embedded within distribution networks. In the last<br />

financial year, 63 percent of electricity for sale to consumers<br />

was generated using renewable resources, a<br />

decline on last year due to the extra generation required<br />

from thermal plants. <strong>Meridian</strong>’s contribution to total New<br />

Zealand electricity generation was 11,914 gigawatt hours,<br />

approximately 30 percent of the country’s supply.<br />
