Engineers say they have restored gas supplies to two towns in Aberdeenshire and Moray.
Huntly and Keith lost their supplies on Friday morning.
About 4,500 properties in the same towns lost gas in February at the height of the cold winter weather.
Distributor SGN said the issues which had affected supplies had been resolved on Saturday morning and that customers were able to begin using gas again after following safety guidance.
On Friday, HM Coastguard helped distribute electric heaters and hot plates for cooking food to affected homes, on behalf of the energy supplier.
Residents were asked to turn off their gas supplies at the meter, after switching off gas appliances.
In a statement on Friday night, SGN said: "While we've been able to restore gas supplies to the local hospital and care homes, gas is still not available for the majority of affected properties.
"Our engineers will continue working through the night and we're aiming for everyone to be allowed to switch gas supplies back on tomorrow."
