Residents worried about winter power supply

Christchurch residents in earthquake-hit eastern suburbs are worried that the damaged electricity grid will struggle to supply enough power for household heating appliances this winter.

Lines company Orion says it is possible that more underground power lines will fail in winter as electricity loads increase.

But chief executive Roger Sutton says it is bringing in more diesel generators as a back-up measure and is building new overhead power lines.
