Are you paying more for electricity than you need to? In Chula Vista, timing your energy use can make a big difference in your SDG&E bill, especially if you drive an EV or plan to add a heat pump. You want a plan that fits your daily routine without constant micro‑managing. This guide breaks down how SDG&E time‑of‑use plans work, which options tend to fit common Chula Vista households, and easy steps to cut costs by shifting when you use power. Let’s dive in.
How SDG&E TOU plans work
Time‑of‑use (TOU) pricing means the price you pay for electricity changes by hour. SDG&E sets “on‑peak” hours when demand is highest and “off‑peak” or “super off‑peak” hours when rates are lower. If you can move energy‑heavy tasks into cheaper hours, you can lower your bill without changing your total usage.
You can review plan basics and current options on SDG&E’s pricing plans overview and the SDG&E time‑of‑use guide. Plan names, windows, and prices change from time to time, so always confirm details before you switch.

Why timing matters in Chula Vista
Chula Vista’s climate is generally mild with warmer inland summers. Air conditioning tends to peak in late afternoon and early evening, which often lines up with typical on‑peak windows. That means your AC use can be the most expensive part of the day.
California households also tend to use less electricity than the U.S. average, but EVs and electric heat pumps can change that pattern quickly. According to the California energy profile from the U.S. Energy Information Administration, statewide usage patterns reflect the mild climate, yet electrification can add significant evening and overnight loads.
Pick the right plan by household type
Every home is different, but a few common patterns can guide your choice.
Typical home without an EV
If your main electric use is AC, laundry, and cooking, a standard TOU plan can help if you avoid heavy use during on‑peak. Run your dishwasher and dryer in off‑peak hours. On hot days, set your thermostat to pre‑cool slightly before peak, then raise it a degree or two during peak.
You’ll likely see modest savings if you can consistently shift those flexible loads. If you cannot avoid late‑day usage, focus on small changes that add up, like using appliance timers or delaying laundry.
EV owner who charges overnight
Overnight charging is your biggest advantage. EV‑focused or TOU plans with very low overnight rates often deliver the highest savings if you schedule nearly all charging while you sleep. A Level 2 smart charger or your vehicle’s built‑in schedule makes this easy.
If you can keep charging out of the early evening, even a plan with higher peak prices may still be best for you. See SDG&E’s EV resources for programs and tips: SDG&E electric vehicle resources.
EV owner who plugs in right after work
Charging right after your commute often overlaps with on‑peak hours. That can get expensive. You have two choices: switch to a plan with lower evening costs, or change your charging habit.
If you can’t avoid evening charging, compare plans carefully so you aren’t paying the steepest rates for your biggest load. A smart charger that delays charging to late night can transform your bill.
Heat pump home (HVAC and/or water heating)
Heat pumps shift energy from gas to electricity. In Chula Vista, cooling loads typically drive costs on hot afternoons and evenings. Look for a plan with manageable evening peak prices, then use a smart thermostat to pre‑cool during cheaper hours and ease back during peak.
For heat pump water heaters, schedule heating cycles for off‑peak or overnight. Small setpoint tweaks and scheduling can keep comfort high while lowering your bill.
EV + heat pump household
You have two big loads at different times: overnight (EV) and late day (AC). Start with a plan that offers very low overnight rates for EVs, then reduce evening HVAC costs with pre‑cooling and small setpoint adjustments. If your AC use is heavy and unavoidable during peak, compare plans that soften evening pricing and weigh the trade‑offs.
What to check before you switch
A little prep helps you choose with confidence.
- Gather your usage data. Pull 12 months of interval or monthly data from SDG&E My Account. Hourly data is best for TOU comparisons.
- List your flexible loads. Note when you typically run your EV charger, dryer, dishwasher, pool pump, and other big appliances.
- Compare plans with your actual history. Use SDG&E’s online tools within My Account to see how each plan would have priced your last 12 months.
- Check seasonal patterns. Summer can be very different from winter. Focus on days when AC use spikes.
- If you have solar, align exports and use. Midday solar exports are usually less valuable than late‑day consumption. Consider how a battery or more aggressive pre‑cooling might help.
Simple tools that make savings stick
- Smart EV charger or in‑car schedule. Set it to start charging late at night and finish before morning.
- Smart thermostat. Pre‑cool before peak, then raise the setpoint slightly during the most expensive hours.
- Appliance timers and smart plugs. Delay dishwashers, dryers, and pool pumps into off‑peak or overnight windows.
- Home energy app. Track your patterns and adjust schedules as seasons change.
Quick TOU habit shifts
- Charge EVs from late night to early morning.
- Run dishwasher and laundry during off‑peak.
- Pre‑cool your home slightly before peak on hot days.
- Nudge thermostats a degree or two higher during peak.
- Avoid electric oven use during peak when possible.
Solar owners in Chula Vista
If you have solar, your daytime exports may not match the highest‑value hours. That means every kilowatt you use in the evening can cost more than what you earned at midday. You can improve your results by pre‑cooling your home, shifting flexible loads to off‑peak, and considering storage if it fits your budget and goals.
Common pitfalls to avoid
- Assuming any TOU plan will save you money. Savings come from shifting use out of peak hours.
- Testing for only one month. Compare across seasons to see the full picture.
- Ignoring behavior. If you forget to schedule EV charging, costs rise fast.
- Not checking current plan details. Confirm today’s windows and rates on SDG&E before making a change.
Local EV trend to keep in mind
San Diego County EV adoption continues to grow, which means many households now have large, schedulable overnight loads. For statewide context, see the Zero‑emission vehicle statistics from the California Energy Commission. If you own an EV or plan to buy one, building a simple charging routine is one of the fastest ways to lower your SDG&E bill.
