Power supply had been restored to more than over 70 per cent of its customers up to yesterday afternoon, the Jamaica Public Service (JPS) has said.

"While restoration is almost complete in some parishes, the process is progressing more slowly in others," the light and power company stated.

However, JPS added that, up to mid-afternoon yesterday, almost all its customers in the parishes of Westmoreland, Trelawny, St. James, and Hanover had received their power supply. The company, however, said due to the extent of the damage to its power-delivery system in parishes such as St. Elizabeth, Manchester, and Clarendon, restoration work was moving more slowly in those areas.

"Additionally, the heavy rains experienced in some sections of the island yesterday and today have slowed down restoration efforts," the JPS said.

Power supply has now been restored to most essential services, including the National Water Commission pumping facilities and hospitals.

The one outstanding hospital - Black River in St. Elizabeth - was expected to receive power supply yesterday evening.

JPS said it was reminding the public that it was possible for a few customers to be without supply even after most of their parish is energised.

"This could be due to a lack of access to some communities, or to extensive damage on sections of the power delivery system," the light-and-power company said.
