‘Many of our customers in the worst affected areas would not have seen damage like this for years.’

Ausgrid’s Jonathan Hall said the repairs could take a while.

‘Unfortunately, it’s taking time because that does involve in some places putting in new power poles and new power lines and unfortunately that type of repair takes some time,’ he told ABC.
