How Agile Octopus pricing works
Agile Octopus charges a different price for every half-hour, linked to the wholesale market. Octopus publishes tomorrow's prices at around 4pm each day.
Prices are usually lowest overnight and in windy or sunny spells, and highest from 4pm to 7pm. When there's more power than the grid needs, prices can drop below zero and customers are paid to use it. At peak times Agile can cost more than the price cap rate, so it suits homes that can move their usage.
