Avoid Peak Hours

Electric use is highest on weekdays between 4:00 p.m. and 9:00 p.m.—the time when most people are arriving home, preparing dinner, and settling in for the evening.

We understand it’s not always practical to change daily routines, but this time period has a major impact on system costs. In fact, about 40% of East-Central Iowa REC’s wholesale power costs are driven by demand during these peak hours, when electricity is also most expensive to supply.

Even small shifts when electricity is used can make a meaningful difference. Using less power—or shifting usage to later in the evening—helps the cooperative manage costs and keep rates more stable for all members.

Simple Ways to Help During Peak Hours

  • Run dishwashers, laundry, and other major appliances later in the evening 
  • Use smaller appliances (like microwaves or slow cookers) instead of ovens or stovetops when possible 
  • Choose energy-efficient appliances, such as those with the ENERGY STAR® label 
  • Build energy awareness into your daily routine 

Use the energy you need—just be mindful of when you use it. Together, we can reduce peak demand, avoid the need for costly new infrastructure, and help keep electricity affordable for all members.
