Our three traditional electric utilities — Alabama Power, Georgia Power, and Mississippi Power — serve more than 4 million retail customers. These subsidiaries provide retail electric service and are regulated by federal energy agencies and the public service commissions in the states they serve. The state commissions determine fair electric rates, oversee what project costs (such as those associated with environmental controls or plant construction) can be recovered and define the profit margin utilities can make in retail markets.

Independent customer satisfaction surveys are a key performance indicator for our electric utilities, which consistently rank in the top quartile in both the American Customer Service Satisfaction Index and the JD Power & Associates Electric Utility Rankings.
