Daily On-Peak:  Mondays,  Tuesdays, Wednesdays, Thursdays, and Fridays; except those occurrences where an approved holiday falls on that day

Daily Off-Peak:   Saturdays, Sundays, and approved holidays

Approved Holidays:

Memorial Day - Last Monday in May
Independence Day - July 4 (observed July 5 in the event that July 4 falls on a Sunday)

Reserving Across Multiple On-Peak and Off-Peak Periods

MPS does not make distinctions between "on-peak" and "off-peak" periods when defining service types.  Service types which contain different pricing for "on-peak" and "off-peak" periods are posted for the "full-period".  When making transmission reservations for schedules that span different pricing for "off-peak" and "on-peak" periods, the customer should make reservations using the schedule type listed with "full-period".  The customer will be billed appropriately with "off-peak" prices for those portions of the schedule that are "off-peak" and "on-peak" prices for those portions of the schedule that are "on-peak".
