offpeak

Off-peak, or off-peak period, refers to times of lower demand for services such as electricity, public transit, telecommunications, and travel. The term describes periods when usage is comparatively light and system congestion is likely to be reduced.

In electricity pricing, off-peak periods are central to time-of-use tariffs. Utilities may offer lower rates outside of peak hours to encourage shifting consumption to times of lower demand. Off-peak hours vary by region and season and often occur overnight or early morning. Customers with capable meters can save money by running high-energy appliances, such as washing machines or storage heaters, during these periods.

In transportation and services, off-peak periods may feature cheaper fares or reduced service frequency that aligns with lower demand. Transit operators promote off-peak travel to spread crowding and use capacity more efficiently. In telecommunications, many plans include lower rates for off-peak calling or data use.

The concept is used in demand management and energy policy to smooth demand, reduce peak load, and improve grid reliability. Not all regions offer meaningful off-peak discounts, and benefits depend on tariff structure, meter capability, and individual usage patterns. Consumer awareness and flexible scheduling are essential for maximizing advantages. See also peak, demand response, time-of-use pricing.
