Duke Energy is again apologizing to customers — and answering questions from lawmakers Tuesday about delays in getting customers' power restored more than a week after Hurricane Irma.

State leaders who represent Seminole County asked Duke Energy why they had problems with their notification system and why it has taken so long to restore power to customers in the area.

A spokesperson for the company again apologized for technical glitches he said caused issues with notifying customers about the status of their power restoration.

State leaders demanded the utility make changes to their infrastructure in hopes that might prevent as many people from losing power the next time Floridians face another disaster such as Irma.

Duke Energy said it would have power restored to most of Seminole County customers by 11 p.m. Monday. The company said there are still almost 8,000 customers without power as of Tuesday. Duke said those areas incurred extensive damage, and it hopes to get all of those customers back on the grid by Tuesday evening.

“We’ve not lived up to our expectations, we’ve not lived up to your expectations and we’ve certainly not lived up to our customers expectations," Duke Energy's Chris Flack said. "So as we talk about lessons learned and moving forward, this will be something we are focused on and something we’ll continue to look at.”

Republican state Rep. Bob Cortes, R-Altamonte Springs, also sent a letter to Duke Energy, asking them to explain why it has taken longer to restore power to thousands in Seminole County.

Duke had originally told Central Florida customers they would get their power back on by Sunday night; however, the company said technology issues forced more delays.

“Unfortunately in this instance, we didn’t provide the experience that a lot of our customers wanted,” said Jeff Brooks with Duke Energy. “We had some costs that caused us to revise some estimates, and we apologize for that. That was totally on us, so that’s something we’re going to work to improve on.”

Veronica Abreu says her family was one of a just a few in her Seminole County neighborhood still without power on Tuesday morning. By the afternoon, her power was restored. But Abreu says it wasn’t just being without power that frustrated her.

“When we would call and report it everyday, it would say we were the first person to report it. So who knows how long it was until they even knew that we didn’t have power,” said Abreu.

As of Tuesday evening, Duke Energy officials said they had restored power to all but 2,770 customers in Seminole County. The electric utility reported 3,850 customers in Orange County were still without power. The utility says all Central Florida customers should have power restored by Tuesday night.
