What Summer Power Costs Look Like in Mesa

If you’re new to Mesa or considering a move, brace yourself for some sticker shock when it comes to summer energy bills. While the dry heat is great for your sinuses, it’s not so friendly on your wallet. Expect your electricity costs to potentially double or even triple during the peak of summer compared to more temperate months.

So just how high do those bills climb? According to local utility data, the average July electric bill in Mesa is about $220. That’s for a typical 1,800 square foot home. If you have a larger house, less efficient AC, or really like to crank the cooling, you could easily see bills pushing $300 or more during the hottest months.

While those costs can be tough to swallow, they’re pretty much the norm for the Phoenix metro area. Mesa’s summer energy bills are on par with nearby cities like Chandler, Gilbert, and Tempe. But knowing you’re not alone doesn’t make it any easier to pay those peak season power bills.

Why Are Energy Bills So High in Mesa During the Summer?

It really comes down to one thing: air conditioning. Cooling costs are far and away the biggest driver of those sky-high summer electric bills in Mesa. When the mercury regularly tops 100°F and barely dips below 80°F at night, your AC is running almost nonstop to try to keep your home livable.

Older homes with dated insulation and leaky ductwork make the problem even worse. Your AC has to work that much harder to keep the heat out. And with the sun blazing for 14 hours a day in July, there’s a lot of heat to contend with. Even energy-efficient homes can struggle to keep cooling costs in check.

On top of the AC, other summer-specific energy needs add to the bill. Think pool pumps running overtime, extra loads of laundry from sweaty clothes, fans and portable coolers, and even a boost in refrigerator usage from thirsty kids grabbing cold drinks all day. It all adds up.

Ways to Lower Summer Energy Bills

While triple-digit bills are the norm, there are things you can do to keep costs from skyrocketing even higher. Some top tips:

  • 🏆 Energy Tip: Set your thermostat to 78°F during the day and use ceiling fans for added comfort. Every degree above 78°F saves 3-5% on cooling costs.
  • Take advantage of off-peak hours. Do laundry and dishes at night or early morning to avoid peak rates.
  • Upgrade to a smart thermostat that automatically adjusts temps when you’re away.
  • Have your ducts inspected and sealed to improve efficiency.
  • Use shade strategically. Plant trees, install awnings, or add solar screens to block sun.

Time-of-Use Pricing in Mesa

Many Mesa residents have the option to choose a time-of-use (TOU) plan from their electricity provider, either SRP or APS. With TOU pricing, you pay different rates depending on when you use energy.

Peak hours, typically weekday afternoons and evenings, have the highest rates. Off-peak hours, like nights and weekends, offer a discount. The idea is to shift more of your energy use to off-peak times to save money.

TOU plans can be a good option if you’re able to adjust your energy habits. But be aware that peak rates are even higher than standard plans. So you have to be diligent about running major appliances during off-peak hours to see savings.
