<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 />
