01 The objective

One optimisation.
Solved every half-hour.

Every schedule Electryone writes answers one question: how much value can the depot capture tonight, without giving up anything the fleet needs?

Maximise Savings + flexibility revenue
16:00 Value captured tonight 08:00
Subject to Every vehicle at its target charge by departure 40 / 40
Site import within the grid connection 680 kW / 1,000 kVA

Market commitments sized to what the fleet can deliver Sized to fit

Solved again whenever a departure, tariff, price or market event changes. Figures are for an illustrative depot.
02 The economics

Five ways the same
kilowatt-hours pay.

Read it as a sum: start from the unmanaged bill, take off what better timing saves, then add what the fleet's flexibility earns. One schedule does it all, inside the same limits.

03 The constraints

Profit never outranks
the fleet.

Departures, the connection, charger and vehicle limits, and market commitments are hard limits in the optimisation, not targets to trade off.

Departures
Ready before every shift
Each vehicle has a departure time and a target charge. The plan meets both, then looks for value in the hours left over.

Night plan: each vehicle charges in the cheapest overnight half-hours, vehicles plugged in during a Demand Flexibility Service event are held through it, and a wholesale position covers the overnight charging.

Connection
Inside the grid connection
Charging, offices and workshops share one import limit. The schedule never plans past it, whatever the market pays.

04 The difference

Smart charging saves.
Electryone also earns.

The same depot on the same night, three ways. Each gets the fleet out on time; only one turns the night's flexibility into revenue.
