Thermal Battery
Thermal Battery is grid storage. It does not generate or consume UE in normal operation—it absorbs surges and covers spikes.

Pipeline Behavior
Section titled “Pipeline Behavior”Treated as storage, not a normal consumer:
- Pipeline >5% fuller than battery → charge battery (≤600 UE/s per side)
- Battery >5% fuller than pipeline → discharge to pipeline
- Stored UE also marks the network as powered
Generators feed machines first; overflow fills the battery.
Visuals
Section titled “Visuals”- Light intensity = current / max UE
- Animation on UE change
- Full charge: persistent glow overlay
Item Form
Section titled “Item Form”Picked-up battery keeps UE—move a full battery without losing charge.
Layout
Section titled “Layout”- Trunk pipe ↔ battery ↔ heavy consumers for spike smoothing
- Several generators + one battery beats many batteries alone
- Weak passive gen (wind/hydro) + battery banks output for burst machines
