FIJI Industries Limited will normalise its service after the Fiji Electricity Authority restores full power supply.
FIL general manager Mosese Natuilagilagi said the power surge had affected their work in producing cement.
"The machine has been fixed and is running, however the power surge has been a major problem for our cement production," Mr Natuilagilagi said.
He said services continued despite the intermittent power supply.
"We are now normalising our service to hardware shops as our priority.
"We have a backlog list that provides us with our supply for our priority customers," he said.
Mr Natuilagilagi said they extended their priority service to certain companies that need cement.
He urged hardware stores to serve top priority customers first.
He said the 1400 tonnes of cement from New Zealand were still in store to assist the local distribution but those would cost a bit more than the price for local cement.
"The varying price in hardware stores is because the New Zealand cement is expensive," Mr Natuilagilagi said.
"Most hardware stores might have priority customers. I urge them to service big contractors first who are in need of cement to complete projects that were on hold during the shortage."
So far, he said small companies were affected because of their priority list of supply.
Once FEA normalises power supply, he said operations would continue in full gear by the end of next week.
