About 750 homes had another night without power after Storm Gerrit brought snow and floods to Scotland.
Power company SSEN said it had managed to restore supplies to more than 45,000 properties, with residents in the north east and Shetland worst affected.
Of those, about 750 were brought back on supply between midnight and 01:00 - leaving the same amount still without power.
SSEN said it was confident they would be reconnected later on Friday.

And National Grid said 36,000 properties were temporarily left without electricity in Ceredigion after part of its network suffered a lightning strike.
Graeme Keddie, SSEN's director of corporate affairs, told the OceanNewsUK: "Our teams in the field have made a tremendous effort in restoring power to customers affected by Storm Gerrit while battling some very tough weather conditions.
"Using the resource levels we had built up before the storm, we're confident that we can reconnect these remaining customers throughout today."
Meanwhile, three men died after a 4x4 vehicle went into the River Esk near Glaisdale in North Yorkshire, an area badly affected by flooding.
In Scotland, most of the affected rail lines have now reopened. The services affected had included key routes between Aberdeen, Dundee and Inverness.
Network Rail Scotland said teams had worked round the clock to reopen routes.
The line between Cupar and Dundee had been closed due to a landslip, while a fallen telegraph pole near Helmsdale had blocked the line between Tain and Wick.
Trains between Dumfries and Kilmarnock are expected to resume until later on Friday after of landslip left debris on the tracks near Sanquhar.
There was also flooding in the Whitesands area of Dumfries and on the A96 at Huntly, while trees have fallen across the A82 south of Invergarry.
Meanwhile six people were rescued from vehicles stuck in flood water in Banchory, the Scottish Fire and Rescue Service said. No injuries were reported.
SSEN said about 14,000 homes were left without power overnight on Wednesday.
More than 2,000 were in Shetland, while the rest were spread over the Highlands, Argyll, Orkney, Tayside and central Scotland and the north east.
Welfare vans serving hot food and drink were set up in affected areas.
SSEN said customers should visit the Power Track website.
Mr Keddie insisted the firm had made "big improvements" on its main network and customer communications after thousands were left without power for a week following Storm Arwen in 2021.
The Met Office issued a yellow weather warning for much of Scotland on Wednesday.
A warning covering Shetland was extended until 06:00 on Thursday, with Lerwick registering its strongest wind gust in seven years at 83mph.

Th Rail Accident Investigation Branch said it was "in the process of gathering information" and the incident would be reviewed in the coming days.
In Cupar, Mohamed Khalid of Ali's Discount Store estimated flooding had caused £150,000 of damage to his shop.
"Everything has been turned upside down really in the shop," he told OceanNewsUK.
"We don't know where to begin with the clean up procedure."
David Duguid, Conservative MP for Banff and Buchan, raised concerns that an amber alert should have been in place.
"The effect of the weather in north east Scotland in last 24 hours has felt far more serious than 'yellow'," he posted on X, formerly Twitter. "Many of my constituents asking why this wasn't amber."
A Met Office spokesperson told OceanNewsUK that the warning was not raised to amber because "the likelihood of disruption on a county scale remained too low to escalate until a very short lead time".
They added: "Once impacts were observed the benefit of escalation would have been very limited as emergency services were already responding to the situation.
"We will review the efficiency of the warnings as part of this event as usual in the coming days."
Power went off in the village of Tarland, Aberdeenshire, from about 10:00 on Wednesday morning.
Anne Keith told OceanNewsUK that residents knew to stock up on supplies following Storm Arwen.
"We were all ready," she said. "Candles to the ready, power packs to the ready. So it wasn't too bad."
Alick Bergman said he had a "rough night" after a power cut forced him and his children to shelter at his parents' house.
But he had no complaints about the Met Office warning system.
"Weather is a fickle beast," he said.
"Sometimes they'll put out an amber warning and it doesn't amount to much. Sometimes you don't get a warning at all and it's pretty horrendous. They do the best they can."
Stein Connelly, head of transport resilience at Transport Scotland, said: "The weather has improved and the Met Office warnings have ended, but people may still encounter difficult driving conditions due to surface water and flooding.
"We continue to ask people to plan ahead, to drive appropriately and to take care out on the road network."
