Essential Energy is offering small portable loan generators and fuel vouchers to all customers without power across the bushfire-affected areas. So far, more than 60 customers have taken up the generator offer, while "several hundred" fuel vouchers have been handed out.

Essential Energy is asking customers who remain without power as a result of the bushfires across the Snowy Valleys, Riverina and south coast areas to make contact to discuss ongoing power needs, as repairs to the network and power restoration work continues.

Over the past week Essential Energy has attempted to contact all customers without power to discuss their current arrangements and estimated restoration dates, however, there are a number of customers who have not been reached after multiple attempts, and it is these customers that are being encouraged to contact Essential Energy on 13 23 91, operations manager Ian Armstrong said.

Essential Energy is also sending text messages to these customers, urging them to make contact.

"If people know their neighbour or other members of the community are away, possibly staying with friends or family, or in need of assistance with a generator we ask them to reach out and have them call Essential Energy," Mr Armstrong said.

Essential Energy crews have restored power to more than 36,000 customers since New Year's Eve.

Bushfire-affected families and businesses can also now access all available assistance being offered by local councils, the state government and federal government, through the NSW government's new bushfire customer care program. Call the program, between 7am and 7pm, on 13 77 88.
