Although weather forecasters warned last week that Hurricane Sandy's high winds could result in lengthy power outages, the blackout that has now lasted for close to four days in some parts of the area is causing confusion and frustration for many local residents who remain in the dark.

That is evident on PPL's Facebook page, where the utility has been posting frequent updates about progress on its restoration efforts for customers in a 29-county area that includes the Lehigh Valley.

Locally, the north end of Hellertown and parts of Lower Saucon Township remain in the dark as of Friday, along with much of Williams Township, Fountain Hill and eastern Salisbury Township.

And patience is wearing thin for some customers whose homes are growing colder by the hour.

In particular, electric customers are voicing growing anger over incorrect "ERTs" (estimated restoration times) that PPL has been providing via its Outage Center.

"No excuse to have ours postponed each night for 2 in a row now," wrote Justin Adam Burkhardt on the PPL Facebook page. "It's either lies, appeasement or false hope or incompetence. We are freezing and waiting still in fountain hill!"

Added Sonia Carballo on the same thread: "When you issue out ERTs people think its an exact time (give an hour or two). Don't give out ERTs until workers get there an assess the situation. You're only upsetting people!"

And Tom Moran said he was disappointed not to see power crews in Tatamy and Forks Township after receiving a message stating that crews were on site.

"Dont just send messages to make us feel some glimmer of hope and your not even there," he wrote.

Facebook user T'Shawn Rivers questioned whether "politics are playing a role in who receives service."

"There are a lot of upset people in Paradise Township with illnesses, fixed incomes and limited mobility who have been without power for five days," she wrote in a message posted to the PPL Facebook page timeline. "Food spoiled, money wasted. This is just not right. And the ERT schedule keeps changing. This is just not right."

Some customers, however, defended the utillity company for working around the clock to restore power to hundreds of thousands in the aftermath of the historic storm.

"You need to understand they are dealing with major issues in a lot of areas," commented Facebook user Bill Cuthbertson, in a reply that received seven "thumbs up" from others. "After a storm like Sandy, a week without power in the grand scheme of things is nothing. We should be grateful for the hard effort being made to restore our power--as hard as it is--because it's the right thing to do."
