Peaks occur in the mornings from 6 a.m. to 10 a.m. and in the evenings from 5 p.m. to 9 p.m. on especially cold days. You’ll receive a notification in the app the day before a challenge.
You may also be notified of two challenges—one in the morning and one in the evening—on the following day.
During cold snaps, there may be challenges on several consecutive days. In the exceptional case that an unplanned event occurs on the power system, you may be notified only a few hours before a challenge.
