FETCHING AGILE HISTORY — PAGE 1…

ℹ HOW THE NUMBERS WORK: GRID P&L = Real cash. Export income − charge cost. What Octopus pays Dovecote for grid exports minus what Octopus charges to charge the battery. This is the actual bank account movement — no modelling, no assumptions. The battery also covers the home's 12kWh/day consumption from its charge cycles, meaning the homeowner pays £0 for electricity up to that cap. The Grid P&L proves the system is commercially viable even after providing that free electricity. AGILE TARIFF SAVING (indicative) = Per-slot saving from buying on Agile vs the Ofgem Standard Variable Tariff (25p/kWh reference), weighted by the Elexon PC1 domestic load profile across 12kWh/day. This is NOT cash paid by Octopus — it is the financial benefit of being on Agile instead of SVT. Shown for context only. NET VALUE = Grid P&L + Home Energy value. Combined annual benefit to the household. The chart above plots this.

HOW YOUR NODE-3 WORKS FOR YOU

⚡ CHEAP HOURS

At night when electricity is cheapest (often negative price!), Node-3 fills the battery for free — or gets paid to charge.

🏠 YOUR HOME

During the day your home runs off the battery. You pay £0 for electricity up to 12kWh/day. Savings appear on your energy bill.

💰 PEAK EXPORT

At peak hours (5–8pm) the battery sells electricity back at premium prices. This income funds the service — your savings are free.
