Power Rush Hour

Power Rush Hour occurs during the four-month period (June – September) that determines our transmission costs each year. Also known as 4CP, it’s the measure of PEC’s total energy demand when our statewide transmission system experiences the most overall demand — the four “peaks” — each summer. Peaks tend to occur on the hottest days of the month (one each in June, July, August, and September), usually between the hours of 2 and 6 p.m. Learn more about peak events »

By working together to use less energy during Power Rush Hour, you and your fellow members can help reduce your transmission costs the following year.

Shift today, save tomorrow

The power to have a lower bill is in your hands. Thanks to our members’ efforts to reduce and shift their energy use last summer for just a few hours a day, we avoided $1.4 million in additional transmission costs this year. Let’s work together this summer for even more savings in 2019!
