Marietta is metro Atlanta's great exception: the city runs its own electric utility and its own Board of Lights and Water, so most Marietta addresses deal with city operations for power and water alike — a completely different experience from the Georgia Power suburbs surrounding it. Even here, though, gas follows the statewide marketer-choice model.
The Marietta Square anchors one of the metro's oldest cities, and its utility independence is part of the identity: the Board of Lights and Water has run local service since the era of streetcars, making Marietta a genuine island of municipal power in Georgia Power's metro.
Marietta runs on Georgia's two-season calendar, and utility setup should too. From May into September the air conditioner does most of the talking, so summer movers want electricity live with the City of Marietta before the truck is unloaded — a July afternoon in an uncooled house here is its own argument for planning ahead. Gas earns its keep at the other end of the year: plenty of the older homes around the Square and the neighborhoods radiating from it heat with gas, and since Atlanta Gas Light delivers while a marketer you pick handles billing, choosing that marketer before the first real cold snap beats scrambling in November. Water through the Board of Lights and Water rounds out the list in any season.
