Edison International is the holding company for Southern California Edison, one of the largest electric utilities in the United States. Its core job is to deliver electricity to homes, businesses, and industrial customers across much of Southern California, using a network of power lines, substations, and other grid equipment. It also buys and manages the power needed to serve customers, but the customer-facing business is mainly about keeping electricity flowing reliably.

The company makes money through regulated electric rates set by public regulators. Customers do not shop for Southern California Edison the way they might shop for a retail product; instead, the utility earns allowed returns on the wires, poles, and grid assets it builds and maintains. That makes the business model more like a regulated infrastructure company than a competitive seller of electricity.

What makes Edison International different is that its earnings depend heavily on the size, safety, and reliability of the electric system it operates, and on how regulators treat those investments. Its main customers are ratepayers within its service area, while its main counterparties are state and federal regulators that approve how much it can charge and what costs it can recover. This gives the company a stable but tightly controlled role in the power value chain: moving electricity from the grid to end users rather than competing to sell power in an open market.
