Peak Energy Hours: Time of Use Conservation

It is always important to try and conserve energy but during certain times of the year, there are particular hours in the day in which it is important to be extra mindful of energy usage.

Summer Peak Energy Information

From June through September, peak energy hours are from 2–8:30 p.m. Energy costs increase during these hours so make sure to plan any high-energy-consuming activities for the morning. Here are a few easy things you can do to help:

  • Take advantage of natural light
  • Turn off the lights when you’re the last to leave a room
  • Shift large print and copy jobs to before 2 p.m.
  • Schedule meetings for after 2 p.m.
  • Power down unused computers and other electronic appliances
  • Keep outside doors and windows closed to conserve air conditioning
  • Take the stairs and limit your use of elevators

Winter Peak Energy Information

From December through March, peak energy hours are from 5–11 a.m. Energy costs increase during these hours so make sure to plan any high-energy-consuming activities for the afternoon. Here are a few easy things you can do to help:

  • Take advantage of natural light
  • Turn off or reduce your use of heating
  • Minimize your use of hot water
  • Dress warmly to reduce heating
  • Print or copy large documents in the afternoon
  • Power down electronic appliances not in use
  • Take the stairs and limit your use of elevators and automatic doors

Faculty and staff who operate dishwashers or laundry machines or stock refrigerators and freezers as part of their jobs should conduct this work outside of the peak use times on weekdays or on weekends.

Peak times for energy use are determined by the Tennessee Valley Authority (TVA) and vary by season. Peak energy use billing, which became mandatory for TVA’s largest customers in 2011, provides the campus with an opportunity to save on energy costs by adjusting study, work, and play habits.

Faculty, staff, and students have been encouraged to change their on-campus energy use habits since the Switch Your Thinking initiative began in 2008. Since then, the campus has saved more than $1 million in energy costs.
