(Corvallis, OR) -- As more utilities switch to time-of-use energy pricing models, residents could save money by changing when they use electricity. A study by Oregon State University and Stanford finds residents aren't aware they could save money by shifting major power uses to off-peak times. Many utilities, including PGE, have smart meters that allow residents to see when they use the most power. If they use off-peak times to wash clothes and run a dishwasher, they could save money. They might also consider buying more energy efficient appliances. The study recommends households check with their utility for off-peak pricing and know how to access data from smart meters.
