How your Intelligent Octopus Flux tariff works

You're on a time-of-use tariff with two rate periods. The key feature is that your import and export rates always mirror each other — so when it's expensive to buy electricity, it's also most profitable to sell it.

The daily strategy: Your battery charges overnight at the cheaper off-peak rate. Then Octopus automatically discharges it to the grid between 4–7pm when the rate is at its highest. This "buy cheap, sell peak" cycle is called energy arbitrage — it earns you money every single day regardless of how sunny it is.

About the accuracy of these figures: To calculate exactly how much you've earned at peak vs off-peak rates, we need to know precisely when each kWh was exported during the day. When you first loaded the dashboard, we only had daily totals, so the figures below are initially estimated using a seasonal model (summers export more at peak, winters less). In the background, the dashboard quietly downloads the detailed half-hourly data for each day — about 30 days per visit — and upgrades the figures to accurate as it goes. The progress bar below shows how far along this is. You don't need to do anything, it happens automatically.
