Octopus Agile is a time of use tariff available in the UK from Octopus Energy.
The tariff varies on a half hourly basis and tracks the wholesale cost of electricity and electricity network costs.
Electric loads such as water heating and electric vehicles can take advantage of time-of-use tariffs by charging at lower cost off-peak times - both providing a direct financial benefit for the household and in turn reducing the infrastructure requirements and associated cost that would otherwise be needed if these loads where added at periods of peak demand.
​
The Octopus Agile tariff is a first of it’s kind in the UK both making use of new smart meter technology and being available nation wide. The tariff is a 100% renewable energy tariff. For more information on the tariff see the Octopus website and associated blog posts:
