Electric System

We're focused on providing reliable service.

Every day, PPL Electric Utilities is focused on operating and maintaining a vast and complex system to keep the lights on and provide reliable service.

  1. Electricity is generated at power plants that supply the regional power grid.
    • Power plants – large and small of all different types – operate independently of local utilities and sell power into a competitive market.
    • PPL Electric Utilities does not own power plants, and you can choose your generation supplier. 
  2. From power plants, electricity travels on high-voltage transmission lines.
    • These power lines allow electricity to travel long distances.
    • Transmission lines across Pennsylvania are interconnected in a network and tie into a power grid throughout the Mid-Atlantic region. 
  3. Electricity next travels to substations.
    • Substations serve as the hubs for local power supply.
    • Fed by the transmission lines, substations control and regulate power for distribution in area cities and towns. 
  4. Electricity then flows along distribution lines to homes and businesses.
    • Distribution lines carry electricity at lower voltages.
    • The electricity is measured as it enters a home by advanced meters that can read usage on an hourly and daily basis.

We prepare all year long to respond to outages, and we proactively trim trees and make other improvements to deliver your electricity reliably and safely.

Damage from storms, animals, vehicle accidents or other factors can disrupt service to your home at any point along the electricity grid. Depending on the type of event, there could be several repairs to make along the grid to restore electricity to your home or business.
