The ACT SES received more calls for help from Monday's hailstorm than it had for the past two years combined. It also beat the previous call record by almost 1000.
Widespread damage from the storms has been reported across Canberra, but appears to be particularly concentrated in the Belconnen suburbs, city and inner south.
As of 7.50am Tuesday, the agency had received 1911 calls for help. It said 445 jobs had been completed and there were 1466 jobs outstanding.
The agency has averaged 600 storm response calls a year over the past two years. Monday's call volume beat the previous record, set more than three years ago, when the ACT SES received 998 calls after a windstorm on January 13, 2017.
The 2017 windstorm brought gusts of up to 69km/h in Tuggeranong and up to 54km/h in other parts of Canberra and felled trees across Canberra.
During Monday's hailstorm wind gusts of up to 116km/h were recorded at Canberra airport.
The ACT Emergency Service Agency said about 35 crews made up of the ACT SES, ACT Rural Fire Service, ACT Forestry and Trees and Transport Canberra and City Services worked overnight on repairing damage.
"It will take a number of days to get through every task. We ask Canberrans to remain patient while they wait for assistance," an ESA statement said.
On Tuesday morning the ACT ESA's incident map still showed swathes of damage to power lines, concentrated in west Belconnen and the inner south.
The high volume of calls meant it took some time for people to be able to connect when calling the SES helpline, 132 500.
"We appreciate your patience as we work through the high volume of call outs," the agency said.
"Residents who require assistance for storm or flood damage are advised to call 132 500. Please only call Triple Zero (000) for life-threatening emergencies."
People concerned about electrical safety were asked to contact Evoenergy on 13 10 93. There were scores of reports of power failures across the city on Monday.
The ESA used the Specialist Intelligence Gathering Firebird 100 helicopter to conduct a damage assessment from the sky.
