Price-responsive setpoints

Strike ($/MWh)Setpoint (kA)

Turn-up price threshold (AUD/MWh)

Above-band sprints (> upper bound, below) are only allowed while price is under this threshold — on top of, not instead of, the hours-above-band budget.

Optimisation & Display Resolution GridBeyond

Adaptive grid (default on): resolution follows an hourly interest score — thermal headroom, price level, and price transitions — instead of a fixed clock-time ladder, so a cool/cheap sprint window anywhere in the horizon gets fine (≤15-30 min) blocks, not just the near term. Turning it off falls back to the fixed 5-tier grid below — near-term resolution until the next hour, mid resolution for the mid window, mid-2 resolution for the following window, coarse for the window after that, then coarse-2 for the rest (default horizon 48 h). Both resample onto the same display grid for the charts. Finer = more accurate but slower.
