One of the headline grabbing features of Octopus Energy Agile tariff is when prices go negative and us end users get paid to use energy.
This occurs when there is too much generated energy on the grid, which usually coincides with high levels of renewable energy on the grid, so windy days/nights and/or lots of sun producing Solar energy.
When this happens, rather than turn equipment off its easier for the National Grid just to dump the energy cheaply onto the grid and pass on the savings to the end user.
National Grid have an article on the subject here: The weekend of free electricity?
And Octopus Energy produced a blog about the daytime plunge in April 2020.
See below for an example of when pricing went negative one afternoon in April 2020. Graph from Twitter @energystatsuk.
So to answer the recurring question “How many times has Agile gone negative?” I’ve pulled that data from all the Agile data (back from Feb 2018) and charted it below.
Note: this data is the from Yorkshire region, but the pricing varies so little region to region, its not worth created 14 different tables.
