What Are Octopus Energy Smart Tariffs?
Octopus Energy offers several time-of-use tariffs designed to reflect wholesale electricity prices in near real time. The most popular is Octopus Agile, which publishes half-hourly rates each day for the next 24 hours. Other tariffs, like Tracker and Go, follow similar principles with different pricing structures.
-
Encourage off-peak usage
-
Reward flexibility in energy consumption
-
Help balance the grid and integrate renewables
We explain what Time of Use Tariffs are in this article:
