Sharjah: The lights came back on in the early hours of Thursday in most of the areas hit by power failures in recent days.
But residents in the densely populated neighbourhoods said they were not holding their breath.
Workers and residents said they did not feel confident the blackouts were over.
Audio: Residents narrate their plight
In some of Sharjah's industrial areas where the power was out for more than 65 hours continuously, small business owners said they had run up huge losses and would take precautions for the future by having a generator handy.
In some parts of the Sharjah Free Zone, thousands of people suffered for four straight days without electricity.
A company manager Philip Pattni said taps also ran dry because pumps could not be operated when the power was off.
Residents expressed their fury at the Sharjah Electricity and Water Authority (Sewa) saying it had blatantly ignored their pleas for help during the sweltering days and nights without airconditioning or water.
The power failures came intermittently and without warning, preventing residents from making other arrangements.
Residents said they were upset over Sewa's "ostrich head-in-the-sand" attitude.
A Gulf News reader said Sewa turned out to be "one of the most irresponsible, unresponsive and callous state organisation that I have come across".
Their "customer care" service number was a joke, he said. No one even bothered answering the 991 number, he said.
The only response was from a Sharjah Chamber of Commerce executive who said the situation would soon return to normal.
There were uncorroborated reports that Sewa was waiting for a gas supply to run the power plants.
Thousands spent sleepless nights in the heat and humidity which reached 75 per cent.
Getting out of residential towers was a nightmare as residents climbed down the stairs in total darkness. ATMs were useless and petrol station attendants turned motorists away.
