How do I set up utilities when moving to Mississippi?

Find which electric, gas and water company serves the new address, then start service online two to three weeks before you arrive, starting on the day you get the keys. Schedule the old address to stop the day after you leave. The Mississippi Public Service Commission regulates utilities in Mississippi.
