PPL set a demand record Tuesday and is asking the public to conserve electricity.
The utility set a record Tuesday morning of 7.6 million kilowatt hours in the 7-8 a.m. hour and then broke that record Tuesday night.
In the 5-6 p.m. hour, there were 7.78 million kilowatt hours of usage, which is enough power for more than 700 average homes for a year.
PPL Spokesperson Joe Nixon said their system is holding up well, but there are steps people can take to help lower the demand on the system.
PJM, the region's independent electricity grid operator, and PPL are asking people to conserve electricity, especially from 6 to 9 a.m. and 3 to 7 p.m.
One thing you can do is set the thermostat lower if you can.
Nixon added, "Postponing use of major appliances like stoves, dryers, anything like that, use those preferably in the middle of the day after 9 p.m."
"You can seal doors and windows if they have drafts with weather stripping or caulking," he said.
Nixon also reminded people to close off rooms not in use and turn off lights and electronics not in use.
Rolling blackouts are not expected, he said.
"There are no plans from PJM at this point to call for those and we're hopeful that's not necessary," said Nixon.
"The work we do all year, the investments we make all year, are really for year-round reliability, but they really pay dividends when it's really hot, when it's really cold."
Nixon said they are having minor issues across their system and have enough people working to handle issues that might arise.
