They manage the local infrastructure, including power lines, substations, and transformers, ensuring that electricity is safely and reliably supplied to consumers. These companies also handle customer service, billing, and maintenance of the electrical grid. They play a crucial role in managing demand and ensuring that the supply of electricity meets the needs of the community. Examples of such companies include Pacific Gas and Electric and Con Edison.
