What Summer Power Costs Look Like in Marietta
Residents of Marietta, GA can expect their summer energy bills to rise significantly compared to the milder spring months. The average monthly electric bill from June through August hovers around $180, a sharp increase from the $110 seen in April and May. The average July electric bill in Marietta peaks at about $210, making it the most expensive month for cooling.
These summer energy bills in Marietta reflect the increased demand placed on air conditioning systems to combat the scorching Georgia heat. Homes with older, less efficient A/C units or poor insulation may see even higher costs. Pools, irrigation systems, and electric vehicle charging can also contribute to steeper summer electric bills.
Why Are Energy Bills So High in Marietta During the Summer?
Several factors drive up energy bills in Marietta during the summer months. The primary culprit is the increased demand for air conditioning to maintain comfortable indoor temperatures. As outdoor temperatures regularly exceed 90°F, A/C systems must work harder and longer to cool homes, consuming more electricity in the process.
Older homes with outdated insulation and air sealing allow more heat to enter, placing an additional burden on cooling systems. Marietta’s long summer daylight hours also mean more time spent indoors using appliances and electronics. In some cases, pool pumps, lawn irrigation, and electric vehicle charging can further inflate summer energy costs.
Heat pumps, while generally efficient, can struggle to keep up in extreme temperatures, leading to longer runtimes and higher bills. Homes with zoned systems or multiple units cooling a large square footage may also see costs rise faster than those with a single, centrally located thermostat.
Sample Monthly Bill Breakdown
To better understand where your summer energy dollars go, consider this sample monthly cost breakdown for a typical 1,800 square foot home in Marietta with average A/C use:

Ways to Lower Summer Energy Bills
While summer heat naturally drives up cooling costs, Marietta residents can take several steps to rein in their energy bills:
- Enroll in off-peak billing or time-of-use rate plans to access lower prices during less busy hours
- Install a smart thermostat to optimize your A/C schedule and avoid over-cooling empty homes
- Have your ducts professionally sealed to minimize air leaks and improve circulation efficiency
- Utilize shade features like curtains, blinds, awnings, and tree cover to block solar heat gain
- Bump the thermostat up a few degrees and use fans to maintain comfort with less A/C strain
🏆 Energy Tip: Set your thermostat to 78°F during the day and rely on ceiling fans to create a cooling wind chill effect. Every degree above 72°F saves 3-5% on cooling costs.
Time-of-Use Pricing in Marietta
Some utility providers in the Marietta area, such as Georgia Power, offer time-of-use rate plans. Under these programs, electricity prices vary based on the time of day and demand on the grid. Rates tend to be highest during weekday afternoons and early evenings (peak hours) and lowest overnight and on weekends (off-peak).
By shifting more of your energy usage to off-peak hours, you can secure a lower rate for a larger portion of your electricity consumption. This may involve running appliances like dishwashers and washing machines at night or on weekends and pre-cooling your home in the early morning before peak rates kick in.
