Additional engineers have been flown into the region from the UK to assist NIE Networks with the task of restoring power.
Around 52 engineers from England were due to arrive on Saturday, with 30 to be used by NIE and 22 to support ESB Networks in the Republic of Ireland, with additional resources to follow.
NIE Networks said they have more than 1,000 staff, including 700 field staff, working to restore supplies to customers as quickly as possible.
The storm caused damage to more than 100 schools and more than 2,300 reported road closures, with 70 trees having to be cleared on Friday just to reopen the M2.
First Minister Michelle O’Neill and Deputy First Minister Emma Little-Pengelly visited NIE Networks in Craigavon on Saturday afternoon to thank the workers.
Ms O’Neill described the storm and its impact as “unprecedented at every level”.
“People will continue to work tirelessly to ensure that people are connected as quickly as possible. It is very difficult given the amount of damage that has been caused, but we are confident that all the work that can be done has been done and we want to thank the staff for all their efforts,” she said.
Ms Little-Pengelly welcomed the extra engineers and said they would highlight the need for this help and support for Northern Ireland in meetings with the Prime Minister and UK political leaders.
The task of reconnecting is expected to become more challenging on Sunday after the Met Office issued a yellow warning for strong winds in Northern Ireland, with potential disruption to transport and infrastructure expected.
This weather warning is in effect from 10:00 AM to 7:00 PM, while a yellow warning for snow and ice is in effect from 6:00 PM Saturday until 10:00 AM Sunday.
Storm Eowyn led to red weather warnings issued on Friday and significant damage to infrastructure and homes in Northern Ireland.
At the peak of the failure, about 30% lost power.
On Sunday afternoon, NIE Networks said approximately 75,000 customers remained without power.
They said power had been restored to 210,000 properties after the devastation caused to the power grid.
Derek Hines, managing director of NIE Networks, said they estimated the task would take 10 days to complete.
“We are still visiting areas where damage has been caused and working on the faults that will restore power to as many homes and businesses as possible,” he said.
“Assessments carried out on the network yesterday have already allowed us to put details of the restoration on our website. Please check the Power Check on our website (nienetworks.co.uk) for an initial estimate of when we will restore power to your location. We will work to further refine these dates and times as we go through the next few days.
“From what we’re seeing so far, we believe it will be about 10 days until we complete the repairs needed to restore power to everyone.”
He added: “Please bear with us while we work through the yellow weather warning today. We will continue to work with the Strategic and Tactical Coordination Groups to leverage as much assistance as possible from other agencies.
“Councils in Northern Ireland have also opened Community Help Centers in their areas where NIE Networks will be present. These details can be found at www.nienetworks.co.uk.’
Mr Hynes urged the public to stay away from damaged electrical equipment and to be careful around fallen trees.
“Please remember our safety message and stay away from damaged electrical equipment,” he said.
“Please take extra care around fallen trees as they often take power poles and cables with them as they fall and call us if you see anything that looks dangerous on 03457 643 643.”
