The nearly 12,000 men and women of Entergy deliver electricity and gas services to 3 million utility customers in Arkansas, Louisiana, Mississippi and Texas, generating annual GAAP revenues of $13.8 billion. Headquartered in New Orleans, we continue to play a driving role in the economic growth of the Gulf South. Our work matters. That’s been true for more than 100 years. And as we look to the next century, we remember the constant that bridges our past and future: We Power Life.
