Sydney neighbourhood data released

The number of households with solar panels has almost doubled, streetlights are fixed in two days and households have cut their annual electricity use by about 2 per cent, according to the latest electricity data released by Ausgrid. The electricity distributor released the latest round of online data sorted by 39 local government areas across its network in late October.

The updated data shows that more than the six months to June, crews attended 1444 sites to remove graffiti, 420 small transformers were installed and just over 14 km of underground local distribution cable was laid.

The number of homes with solar panels doubled over the same period, while it took about an average two-and-a-half days to fix broken street lights.

Ausgrid energy efficiency expert Paul Myors said the amount of power sent to the electricity grid from rooftop solar panels had also significantly increased.

“Over the six months to June, more than 38 million kilowatt hours of electricity from household solar pv systems was exported to the network,” Mr Myors said.

“That’s enough to power 5800 homes for a year. We would expect this figure to increase over the summer months as daylight hours increase.

“Average annual household electricity use also declined in most local government areas. We expect this is a result of several factors, such as a reduction in electric hot water usage.

“It’s likely driven by greater uptake of energy efficient hot water systems and shower heads. But it’s also likely that households are using less hot water through conservation.

“We estimate a household could save up to $100 off their annual electricity bill by reducing their shower time by two minutes, so this should be good news.

“Households are probably also becoming more energy efficient, by turning off appliances and lights when they are not needed. This will translate to good savings on electricity bills.”
