Energy Savings

It’s time for Power Rush Hour

Shift energy use 2-7 p.m.

Power Rush Hour® takes place during the hottest summer months from June through September. During this four-month period, your transmission costs for next year are determined. 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 7 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.
