Tideland EMC’s Plymouth substation was reenergized at 12:30 a.m. Saturday morning restoring power to approximately 900 customers in Beaufort and Washington counties who had been without power since 3:30 p.m. Friday afternoon.
Repair crews determined that the cause of the outage was a damaged substation transformer. The co-op had a spare transformer nearby and a crane was used to put the new transformer in place so crews could restore power.
Tideland EMC revised its projected power restoration time for more than 900 customers in Beaufort and Washington counties to 12:45 a.m. It says due to longer than anticipated transit times a transformer in Plymouth that needed to be replaced will not be activated until then.
At 3:30 p.m. Friday afternoon Tideland EMC lost power to its Plymouth substation. Repair crews determined the cause of the outage was a damaged substation transformer.
The new transformer arrived in Plymouth shortly after 10 p.m.
Tideland EMC says the customers in Washington and Beaufort counties lost power around 3:30 p.m. and they don't expect it restored until around midnight.
Crews have to bring a crane in from Columbia to transport and install a spare transformer inside the Plymouth substation.
Because power is expected to be out for such a long time, Tideland is asking impacted customers to turn off all household breakers that control large loads, such as water heaters and heating systems. Once power comes back on, they're asked to wait 15 to 30 minutes before turning those breakers back on to avoid an overload.
