If your electric bill spikes in the evening or you just added an EV, you have more control than you think. Many Reading households can lower monthly costs by shifting when they use electricity. RMLD’s Time‑of‑Use rate rewards that timing, so you pay less during lower demand hours.
You want predictable bills and simple steps that fit your routine. With a few scheduling tweaks and the right settings on everyday devices, you can make real progress without sacrificing comfort.
In this guide, you’ll learn how Time‑of‑Use pricing works in Reading, who benefits most, how to set smart schedules for HVAC, EVs, and appliances, and how to estimate your savings with confidence. Let’s dive in.
How Time‑of‑Use works
Time‑of‑Use pricing charges different per‑kWh rates based on when you use energy. Utilities set period blocks like on‑peak and off‑peak to reflect system strain and wholesale costs. Your bill still includes fixed charges and delivery fees. TOU changes the energy charge portion.
In Reading, the Reading Municipal Light Department (RMLD) sets the specific TOU windows and prices. These periods can vary by season and by weekday or weekend. Do not assume another New England utility’s schedule will match RMLD’s. Always confirm RMLD’s current TOU hours and prices before you enroll.
New England typically sees higher demand on summer afternoons and evenings when air conditioners run hard. Nights and many weekend hours are often lower cost. That general pattern helps explain why shifting usage away from weekday evenings can reduce your energy charges.
Who saves with TOU
Some homes benefit more than others. The key is how much of your usage you can move to off‑peak hours.
- EV owners who can schedule most charging overnight are top candidates. EV charging is a large, flexible load that is easy to automate.
- Homes with heat pumps or smart thermostats can pre‑cool or pre‑heat before the on‑peak window, then coast through peak hours.
- Households that run major appliances off‑peak using delay start or simple timers often see steady savings.
- Homes with solar plus a battery can store daytime solar and cover evening use during on‑peak periods.
If your usage is already low, or your routine forces heavy evening use, your savings may be smaller. Two households with the same monthly kWh can have very different results based on timing.
Set up smart scheduling
You do not need to overhaul your lifestyle to make TOU work. Start with the loads that are easiest to move, then automate them.
- Identify your flexible loads: EV charging, laundry, dishwasher, electric water heating, space heating or cooling.
- Find RMLD’s off‑peak windows and set schedules to favor those hours.
- Use built‑in appliance timers, smart plugs, or a smart home app to automate.
- Track a few billing cycles and adjust.
Small changes add up. A dishwasher cycle here, a laundry load there, and EV charging overnight can shift a meaningful slice of your usage to lower cost hours.
HVAC and heat pump strategies
Heating and cooling often drive your bill in Middlesex County’s climate. If you have a heat pump or central AC, a smart thermostat can help you pre‑condition your home.
- Pre‑cool or pre‑heat before the on‑peak window. Lower cooling setpoint slightly or raise heating setpoint slightly in advance so your system runs less during peak.
- Relax setpoints during peak. Allow indoor temperature to drift a bit during the on‑peak period, then return to your preferred setting after.
- Use multi‑period schedules. Program a weekday and weekend schedule that matches RMLD’s time blocks.
- Tighten the envelope. Air sealing and insulation help your home hold temperature longer so pre‑conditioning lasts through peak hours.
Comfort should come first. Start with small setpoint shifts and see how your home responds.
EV charging strategies
EV charging is often the single biggest TOU savings lever for Reading drivers.
- Schedule overnight charging using your vehicle’s timer or a smart Level 2 charger.
- Delay start rather than “charge now.” If you plug in during peak hours, set a delayed start so charging begins off‑peak.
- Charge to a target. Set a daily charge limit that meets your next‑day needs so topping off does not spill into on‑peak.
- Coordinate with solar if you have it. If daytime off‑peak exists or you want to absorb midday solar, set a midday top‑up and finish overnight.
Once you set and forget the schedule, you can capture savings every night without extra effort.
Laundry, dishes, and hot water
Appliances are easy to shift and easy to automate.
- Dishwasher: Use delay start so it runs during off‑peak hours.
- Washer and dryer: Run loads in the morning, late evening, or on weekends if those are off‑peak. Clean the lint trap and keep vents maintained for safety.
- Electric water heater: Add a timer or smart controller so it heats during off‑peak windows. A small buffer tank or well‑insulated tank helps maintain hot water through peak hours.
Even if each load only uses a few kWh, the routine savings add up over a month.
Solar, battery, and TOU
Solar reduces your daytime grid usage. If your on‑peak period falls in the evening, a home battery can store daytime solar and discharge into the on‑peak window.
- Discharge during on‑peak. Cover your early evening usage with stored energy.
- Charge off‑peak. If you do not have enough solar or there is a long peak window, consider charging the battery overnight if allowed.
- Check net metering rules. TOU interacts with how exported solar is credited, so confirm RMLD’s current policy before you change settings.
Solar plus storage can smooth your bill and increase resilience. The value depends on battery size, solar output, and the on‑peak duration.
Estimate your bill impact
You can model your potential savings in a simple, step‑by‑step way.
- Gather usage data. Pull a recent bill or, if possible, hourly interval data from your meter or customer portal. Identify when you use the most energy.
- Map to TOU periods. Apply RMLD’s current on‑peak and off‑peak windows to your usage. Be sure to account for seasons and weekday versus weekend if applicable.
- Apply TOU prices. For each period, multiply kWh by the corresponding per‑kWh energy rate. Sum the periods to get your total energy charges.
- Compare to your current bill. Keep fixed charges the same. Compare the energy charge under TOU to the flat rate scenario to see the difference.
- Test shifts. Re‑run the math assuming you move EV charging and appliance use to off‑peak. See how savings grow.
Studies from national labs show households that shift discretionary loads often reduce the energy charge portion of their bills by about 5 to 20 percent. EV owners and homes with large flexible loads can do even better. Total bill savings are smaller than energy‑charge savings because fixed charges do not change.
Reading seasonal tips
Reading’s winters are cold, and summers can be hot and humid. Your best TOU strategy may change by season.
- Summer: Air conditioning drives afternoon and evening demand. Pre‑cool late afternoon, then relax setpoints during on‑peak. Run dishwasher and laundry later at night.
- Winter: If you use a heat pump, pre‑heat before on‑peak and adjust setpoints during peak. If you heat with gas or oil, focus on shifting appliances and EV charging.
- Shoulder seasons: Take advantage of mild weather to run appliances off‑peak and tighten schedules for consistent savings.
Enroll in RMLD’s TOU program
Enrollment details can change, so confirm the current steps and requirements directly with RMLD before you switch.
- Check eligibility. Ask RMLD about available residential TOU plans, opt‑in or opt‑out rules, and any pilot limitations.
- Confirm metering. Some TOU plans require an interval or smart meter. Verify whether your current meter works or needs an upgrade.
- Ask about incentives. Look into local and state rebates for smart thermostats, heat pumps, EV chargers, or batteries that can enhance TOU savings.
- Start a trial. Model your last few months of usage against the TOU schedule. After you enroll, track 2 to 3 billing cycles and fine‑tune schedules.
Safety and equipment reminders
- Use licensed electricians for EV charger or battery installations.
- Maintain dryer vents and avoid running high‑heat appliances when you are away or asleep unless manufacturer guidance says it is safe and you have proper safety features.
- Keep firmware updated on smart thermostats and chargers so schedules run reliably.
What to avoid and common pitfalls
- Chasing tiny loads. Focus on EVs, HVAC, water heating, and large appliances. Small devices matter less.
- Ignoring comfort. Find a balance. A few degrees of pre‑conditioning can deliver savings without discomfort.
- Setting and forgetting forever. Revisit schedules seasonally to match RMLD’s periods and your routine.
- Assuming savings without modeling. Run the numbers. Your load shape and RMLD’s price differentials determine results.
