What University of Arizona Students Pay to Cool a Tucson Apartment Through August

Plan on $95 to $220. That's what a Tucson student apartment electric bill usually hits in August before taxes and fees, if you run Tucson Electric Power's posted 2026 prices against 600 to 1,400 kWh of summer use. Four roommates? Call it $35 to $55 apiece. Air conditioning drives most of it, and because nearly every lease near campus runs 12 months, the August bill is yours whether you're in town or not.

Key Takeaways

• TEP's Basic plan charges 13.04 cents per kWh for the first 500 kWh in summer, rising to 15.73 cents above 1,000 kWh, plus a $15 monthly service charge.
• Summer pricing runs May through September. That's five of your twelve lease months.
• The FMP 21% Rule: on TEP's posted prices, Time-of-Use only beats Basic if less than about 21% of your summer usage falls between 3 and 7 p.m. on weekdays.
• Tucson logged 70 days at 100°F or hotter in summer 2026, against a normal of 55 (National Weather Service).
• A rate increase is pending (TEP has asked regulators for one, so next August could cost more than this one did).
• TEP won't disconnect residential service for nonpayment from June 1 to October 15. The bill still comes due.

What a Tucson Student Apartment Electric Bill Costs in August

Expect about $95 for a careful studio, about $140 for a typical one- or two-bedroom, and about $218 for a four-bedroom house in August. Those are example bills, calculated on TEP's Basic plan with the usage assumptions below. Your real bill adds taxes and fees. These are floors, not ceilings.

• 600 kWh: a studio with the thermostat parked at 80 and the blinds shut. The math is $15 + 500 kWh at 13.04¢ + 100 kWh at 15.01¢, so about $95.
• 900 kWh, which is close to the 823 kWh TEP's rate-review page cites as typical summer usage: about $140.
• 1,400 kWh for a four-bedroom townhouse or older house near West University: about $218, or roughly $55 per person.

For context, the average Arizona household used 1,075 kWh a month and paid $160.24 in 2024, according to the U.S. Energy Information Administration. That figure blends January in Flagstaff with July in Yuma. Tucson in August is not average.

Still comparing buildings? Look at off-campus housing near the University of Arizona with the power bill in your head, not just the rent. A $50 rent difference can vanish by the second bill if the "cheaper" unit faces west and runs a condenser older than its tenants.

Why the bill climbs faster than your usage

Tiers. TEP charges roughly two cents more for each kWh after your first 500, then a little more again after 1,000. Double your usage from 600 to 1,200 kWh and the energy charge goes from about $80 to about $172 (more than double, because the extra kWh all land in the pricier tiers).

Why August Is the Expensive Month for UA Students

August stacks the two things that drive Tucson cooling costs: heat that doesn't break at night and monsoon humidity. The National Weather Service Tucson office puts the normal August at 15 days of 100°F or more, with lows around 75. So the AC is still running at 2 a.m.

And 2026 was worse than normal. Twenty-three triple-digit days in August alone. NWS ranked it the 5th hottest August on record, inside the 6th hottest summer.

Swamp coolers and the monsoon problem

Some older rentals near campus still run evaporative coolers instead of refrigerated AC. They're cheap to run in dry June heat. Once monsoon humidity rolls in during July and August, they lose a lot of their punch, and you end up sweating at a cheaper bill (or running a window unit on top of it). Ask what's on the roof before you sign.

Basic vs. Time-of-Use: Which TEP Plan Saves Students Money

Basic, for most of you. Time-of-Use only pays off if nobody's home on weekday afternoons. On TEP's Time-of-Use plan, summer power costs 19.27 cents per kWh on-peak versus 12.19 off-peak (first 500 kWh), plus a $12 service charge. The on-peak window is weekdays, 3 to 7 p.m., May through September.

That's where the FMP 21% Rule comes from. Running both plans on TEP's posted summer prices, Time-of-Use comes out cheaper only when less than about 21% of your monthly usage lands in that weekday 3-to-7 window. It holds at 600, 900 and 1,400 kWh. At 900 kWh with 15% on-peak, Time-of-Use runs about $136 vs. $140 on Basic. At 25% on-peak, it flips to about $143.

Here's the honest catch. Four roommates on four class schedules? Somebody is always home at 4 p.m. with the AC cranked. A solo renter who spends every weekday afternoon in a lab across campus has a real shot.

What to Ask Before You Sign a Tucson Lease

Three questions: who pays electric, how is it split, and what did last August's bill look like for that exact unit? Get those answers from the leasing office in writing, not from the brochure.

Look at The Mark Tucson, 0.8 miles from campus on N. Park Ave. Four-bedroom plans start at $725 while the three-bedrooms list higher, which only makes sense as per-bed pricing. The Cottages at Tucson on E. 22nd St., 1.8 miles out, follows the same pattern, with a six-bedroom plan listed at $825. Neither listing page spells out which utilities are included. So ask.

• "Is electricity included, capped, or billed separately?" A cap that sounds generous in March gets tested in a 1,400 kWh August.
• Orientation. West-facing rooms take the full afternoon sun.
• The age and type of the cooling system (heat pump, condenser, swamp cooler).
• Whose name goes on the TEP account (and does everyone else Venmo that person)?

Paying for Summer on a 12-Month Tucson Lease

Five of your twelve bills come at summer prices. Spending June at home in Phoenix or Chicago doesn't change that.

Two TEP tools help. Budget Billing spreads your estimated annual charges across 12 equal payments, so August doesn't hit all at once. And TEP won't disconnect residential service for nonpayment from June 1 through October 15. That's a safety net, not a payment holiday. Balances keep growing, late fees can apply, and TEP sets up payment plans for overdue balances after August 15.

One more thing to budget for. TEP has a rate increase request pending before the Arizona Corporation Commission. TEP's rate-review page estimates a median Basic-plan customer using 638 kWh would pay $12.92 more per month. If it's approved this winter, the 2027 summer bill you plan for should be a little higher than every number above.

Frequently Asked Questions About Tucson Student Apartment Electric Bills

How much should I budget for electricity in a Tucson apartment in summer?

$95 to $220 a month for the unit in July and August, before taxes and fees. With four roommates, that's about $35 to $55 each. October through April usually runs much lower, but plan around the August number.

Does TEP require a deposit to start service?

Sometimes. TEP caps residential deposits at two times the estimated average monthly bill. It waives the deposit if you had comparable TEP service in the past two years with a clean payment record, or if you bring a letter from another electric utility showing on-time payments.

Is Time-of-Use worth it for college students?

Probably not for a shared apartment. Under the FMP 21% Rule, Time-of-Use only wins when less than about 21% of your summer usage hits weekdays from 3 to 7 p.m. Most roommate households can't keep it that low in August.

What thermostat setting keeps the bill down?

Somewhere around 78 or 80 when you're there, and 85 when you leave for class. The bigger win is consistency. Cranking it to 68 when you walk in at 5 p.m. makes the AC fight the hottest part of the day and pushes you into TEP's higher price tiers faster.

Can I skip paying my TEP bill in July because of the moratorium?

No. You won't be shut off between June 1 and October 15, but the charges still pile up, and TEP can disconnect you later for the unpaid balance. Call TEP at 520-623-7711 to set up an extension before it snowballs.
