BUSINESSES in the Central Division have to dig deep into their pockets to operate back-up generators.
Food 4 Less manager Pranil Chand said the rationing of power supply affected their operation especially in maintaining the freezer.
"The on and off of power supply has forced us to operate with the back-up generator," Mr Chand said.
"Even with the back-up on, we still had to ration power supply by keeping the freezer on and switching off the light and unnecessary electric appliances. It's expensive to operate the back-up power supply because of the cost of fuel but we have to maintain the frozen goods because we lose more when they are damaged," he said.
Fiji Electricity Authority (FEA) has been rationing power supply after the major transmitter at Wailoa sustained damage.
Food Town Supermarket sales and marketing manager Sanjay Kumar said the power outage was beyond their control.
"Most shops have back-up generators because they don't want their services affected. Our main concern is the frozen goods and also the computerised cash register," Mr Kumar said.
