Charge Director — charge/discharge control · 🇬🇧 United Kingdom
The Charge Director turns the day-ahead price curve into a clear sequence of directives: charge when power is cheap, discharge when it is expensive, otherwise hold. Below is the real optimal schedule for today.
How the director decides
The director sees the full day-ahead price curve of the day and solves, via dynamic programming, the physically feasible optimal schedule of a 2-hour battery (1 MW / 2 MWh): state of charge stays between 0 and full, at most ±1 MW per interval, efficiency applied to discharge. The result is an upper bound (perfect foresight), not live trading.
Daily revenue ceiling
The most this 2-hour battery could earn today on the day-ahead market — pure arbitrage, excluding intraday and balancing markets.
Directive schedule
Each row is a director decision derived from today's real price curve.

Note: outside Germany the Charge Director computes day-ahead arbitrage only. Intraday & balancing markets are currently available for Germany only.
Note: the schedule is a perfect-foresight upper bound based on published day-ahead prices — a model calculation, not a live control signal.
