What if my programmable thermostat has advanced features?

Honeywell RTH7400D 5-1-1 day Programmable ThermostatSome thermostats have advanced features that will achieve your set temperature by the time programmed instead of starting at the time programmed.

  • Check the manufacturer's manual or online information to verify if your thermostat has advanced features.
  • If so, choose settings that limit the time your system runs during higher-cost, on-peak hours.

Why are energy prices higher in the summer?

The kilowatt-hour (kWh) or unit cost of energy is different in winter and summer regardless of your price plan. The price you pay rises and falls with the demand for electricity.

During the coolest months, customer usage, generation costs and the price you pay are lowest. During the hottest months, customer usage skyrockets and generation costs to meet peak demand are highest.

How does a smart meter help me?

On the Time-of-Use Price Plan, you may have a smart meter. If so, it provides more details about when you use energy each day. Available online, any time, this information can help you control costs and manage your energy budget wisely. The "Notes" section of your bill indicates if you have a smart meter.

Smart meters provide detailed information that allows you to:

  • View daily energy usage online. Monitor your daily usage to better understand how and when you use energy.
  • Receive alerts to help manage costs. Set a maximum dollar amount for the month and we'll send an e-notification if it appears your bill could exceed that. You also can sign up to receive weekly bill estimates.
