Residents living near various locations around Lake Marion, rural Manning and parts of Summerton awoke Friday morning to find they had no power.
Santee Electric spokeswoman Adrel Langley said that the outage was the result of an equipment failure.
"I'm happy to report that everything is back to normal now," she said.
Residents began posting on Facebook about 4:45 a.m. about the lack of electricity in their homes. Several reported having power back by 6 a.m., with some reporting getting it back between 6:30 and 7 a.m.
It was the second power outage in Clarendon in as many days.
Duke Energy suffered an outage between 6 and 8 p.m. Thursday at the Walmart shopping center on Paxville Highway.
"We had a transformer that overheated, so we made a repair," said Duke spokesman Theo Lane. "We were working on it by 7 p.m. and had it back up by 8 p.m."
Langley said that the Santee Electric outage affected 6,440 homes.
