AEP OHIO MONITORING EXTREME COLD WEATHER FORECAST

GAHANNA, Ohio, January 18, 2025 - Central Ohio is under an extreme cold watch, with temperatures forecasted to sink to single digits during the day and as low as 20 degrees below zero at night. Extreme weather can lead to significantly increased energy demand, placing pressure on the electric grid. AEP Ohio, an American Electric Power (Nasdaq: AEP) company, is closely monitoring the weather and is providing information to help customers better prepare for winter weather.

AEP Ohio works throughout the year to prepare the electric grid and customers for the unexpected, including extreme weather. From trimming trees away from power lines to updating equipment and adding smart technology, crews work year-round to proactively maintain and improve the system to help prevent power outages.

When it comes to managing energy supply and demand, AEP Ohio is part of the PJM territory, which covers 13 states and the District of Columbia. PJM is a non-profit entity that constantly monitors energy demand. PJM does not own power plants or power lines, but it coordinates with companies that do across its territory, and acts as the "air-traffic control" for power by directing power produced at 1,300 generation sites to meet demand.

In response to forecasted extreme cold temperatures, PJM has issued a Cold Weather Alert, indicating that power generation suppliers should be ready to respond to increased demand for energy.

AEP Ohio is responsible for ensuring power that comes from those generation suppliers is delivered to the distribution customers we serve. Learn more about how AEP Ohio works with PJM.

"Our team continuously monitors the weather to assess and prepare for potential impacts on our customers," said Matt Bennett, director of operations for AEP Ohio. "When weather forecasts predict extreme cold, it is a great time to make sure your emergency kit is up-to-date and to talk with your family to review emergency preparedness plans for the winter. Check in with friends and neighbors to be sure they have a plan, too."

Winter Weather Safety & Preparedness Reminders

• Assemble an emergency preparedness kit. It should include (at minimum) non-perishable food, water, a flashlight, fresh batteries, a battery-powered radio or television, a portable cell phone charging bank, a blanket or sleeping bag, a first-aid kit, cash and any necessary medications. If you have pets, be sure your emergency kit also includes food and any medication they need.
  • Important Note: AEP Ohio strongly encourages customers with life-supporting medical equipment to have a backup power source and an alternate plan in the event of a power outage.
• Remember, all downed lines are dangerous. They carry an electric current that can cause serious or even fatal injuries. If you encounter a fallen wire, keep yourself and others away, and call 911 or AEP Ohio immediately.
• Heat your home safely with tips from the Ohio State Fire Marshal. If using a space heater, place it on a hard, level surface at least three feet away from anything flammable such as curtains and bedding, and out of high-traffic areas. Make sure smoke and carbon monoxide detectors are installed and functioning properly throughout your home and never leave a space heater running when a room is unoccupied.
• Stay connected and make sure your contact information is current. You can enroll in text alerts, and follow us on Facebook or X.
