- Nuclear → low drone
- A steady bass tone. It barely moves, like the plants.
- Hydro → flowing pad
- Warm, slowly swelling chords. Louder when Niagara and St. Lawrence run high.
- Wind → breath and bells
- Air through a filter, with high bells that ring more often as wind output rises.
- Solar and other renewables → plucks
- They play the melody. More output, more notes.
- Gas and dual fuel → saws and brass
- A buzzing drone and short brass stabs. They get harsher and add a clashing note as the clean share drops.
- Clean share → key
- Above about 54% clean the piece plays in a bright major key. In the middle it plays Dorian. Below about 46% it turns to a tense Phrygian.
- Demand → tempo
- A soft heartbeat on every beat. Statewide load sets its speed, from roughly 60 to 135 beats per minute.
- Zone strain → color
- On the map, each zone warms toward red as it nears its highest load in the archive.
