MORE than 900 Ergon workers were on the ground working tirelessly to restore power to the Whitsunday region in the wake of Severe Tropical Cyclone Debbie.

Zone coordinator Geoff McGraw said staff from Cairns to Stanthorpe had heeded to call to restore electricity to the Whitsundays.

All have chosen to forgo being home with their families at the end of the day.

"We don't force people to come on these things, they all volunteer to come down here," he said.

Mr McGraw said the people of the Whitsundays had "overwhelmed" workers with their support and generosity.

"We have got members of the community delivering cookies and biscuits to the guys on the side of the street."

"There was an ice cream truck that stopped and said 'hey guys have an ice cream'."

"They love it," Mr McGraw said.

Keisha McEwan from Proserpine was up one morning at 4am making sandwiches for the Ergon workers.

She works for Westend Cash Store who began supplying workers with their lunches that day.

Normally Ms McEwan gets paid but on that day she donated her time in a gesture of gratitude for what Ergon was doing.

"It was for the Ergon workers, they have been copping so much negativity and I wanted to see a smile on their faces," she said.

"I don't think people understand how difficult it is for them to get out and restore power."

Mr McGraw said crews were working longer days than normal and the management of fatigue to ensure the safety of workers was paramount.

"When you are working around electricity and on the network you need to ensure the guys are able to focus. If they are tired or distracted there is a higher chance of making a mistake."

"Making a mistake leads to putting themselves or the public at risk and we just can't do that."

Ergon Energy's goal was to have as many customers as possible connected to power by Good Friday.

If it was not possible to restore mains power Mr McGraw said Ergon would look at providing power via generators.

"In Wilsons Beach, Conway and Shute Harbour we have gone out and installed generation because we know we are not going to get there before power is restored to higher population zones," he said at the time.

Power was restored ahead of schedule before Good Friday in the end.
