How to place, wire and move parts
Pick a part and click the diagram to place it. Drag a component by its header, or focus it and use arrow keys. Use the Wire tool, or select an output and then an input, to connect components.
Choose a part, then click the diagram where it should go; keep clicking to place more. Add here puts one in the next free spot.
Drag empty space to move around the diagram. Scrollbars and arrow keys work too.

Power reference
Underpowered devices switch fully off
Power in Rust is all or nothing. A device that does not get its full draw is completely off, not running slowly, and while it is off it stops asking for power at all. That is why an underfed circuit does not slowly drain a battery, and why one extra light can switch off the thing next to it.
Wind turbine output by height
Height adds 1.5 rW per metre up to 50 metres. The game adds a changing wind term and caps the result at 150 rW. The table shows only the height contribution with clear exposure.
| Height | Height contribution |
|---|---|
| 0 m | 0 rW |
| 5 m | 7 rW |
| 10 m | 15 rW |
| 15 m | 22 rW |
| 20 m | 30 rW |
| 25 m | 37 rW |
| 30 m | 45 rW |
| 40 m | 60 rW |
| 50 m | 75 rW |
Measure from the turbine base down to the terrain or world surface below, not from sea level or the roof. Raising a turbine on a tower increases this distance. The game caches it when the turbine initializes. Clearance also matters: checks target a point about 21 metres above its base and a point 15 metres horizontally from its rotor height. The horizontal direction turns once per hour of server uptime. If either check is blocked, output is zero.
We do not publish an average output. The changing wind term uses a noise function whose distribution we have not verified. Use the height contribution for conservative planning only when the turbine has clear exposure, and keep battery reserve for interruptions.
How solar panels calculate
An exposed, healthy panel makes up to 20 rW. Output follows the angle between its fixed sensor and the sun, then scales with health. It stops around 73 degrees and reaches its peak around 46 degrees. Night or a blocked line to the sun gives zero. Extra mounting height can clear obstructions but adds no power multiplier.
| Angle | Output |
|---|---|
| 0 degrees | 20 rW |
| 20 degrees | 20 rW |
| 40 degrees | 20 rW |
| 45 degrees | 20 rW |
| 55 degrees | 13 rW |
| 65 degrees | 6 rW |
| 72 degrees | 0 rW |
| 80 degrees | 0 rW |
Face the collecting side toward the visible daytime sun path. The sun's path changes with the server's in-game date, so the best north/south facing can change during a long wipe. Your position relative to the map centre does not decide it. Check output with the Wire Tool in the morning, at noon and in the evening. A 20 rW peak does not prove one panel can run a device through the night: include charging losses, daily generation and battery reserve.
Generator and water wheel output
| Source | Output | Detail |
|---|---|---|
| Small Generator | 40 rW | 14.4 seconds per Low Grade Fuel |
| Water Wheel | 60 rW | 30 rW from flowing water, 60 rW while pedalled. Makes nothing at all in a lake or a swamp. It needs ocean or river water. |
Batteries
A battery drains only what the devices downstream actually ask for, capped at its own output. Charging costs more than you get back: only 80% of what goes in is stored.
| Battery | Output | Max intake | At full output | Auto turrets |
|---|---|---|---|---|
| Small Rechargeable Battery | 15 rW | 60 rW | 27 min | 1 |
| Medium Rechargeable Battery | 50 rW | 200 rW | 3 h | 5 |
| Large Rechargeable Battery | 100 rW | 400 rW | 4 h | 10 |
What everything draws
134 powered items, resolved from the game's own code rather than the prefab field. That distinction matters: a Spot Light stores 1 in its prefab and draws 5 rW. Anything showing 0 is free to run.

What we could not source
Values the game does not ship, or ships without their meaning.
- PerlinNoise
Any average or expected wind output. The turbine adds a changing Perlin noise term whose distribution we did not reproduce, so only the height half and the envelope can be stated.
To settle it: Log a turbine's output on a dev server across several in game days and fit the distribution.
- none
Anything expressed per floor. The 3 metre storey is a community figure we did not verify, which makes any rW per floor number unsourced.
To settle it: Measure the vertical socket offset between building blocks in the prefabs.
- cachedHeight
Whether a turbine over ocean measures its height from the seabed, which would make an over water tower the cheapest route to the cap.
To settle it: Place one on a dev server and read its output.
- IOSlot.mainPowerSlot
Whether a Cable Tunnel adds its 1 rW to a battery's Active Usage. It is the one routing part that does not override ConsumptionAmount, so IOEntity's default 1 stands, which is the number in the table above. ElectricBattery.GetDrain sums DesiredPower over every connected entity, and DesiredPower returns that 1 only when the tunnel's input slot is flagged mainPowerSlot in the prefab, a field we did not read. The line itself loses nothing either way: CableTunnel.UpdateOutputs copies each input straight to its output without going through GetCurrentEnergy, so the builder shows a tunnel passing its input on unchanged.
To settle it: Read the four IOSlot entries on the electric.cabletunnel prefab, or wire a tunnel to a battery on a dev server and read Active Usage with and without it.
- TOD_Time.DayLengthInMinutes
The default day/night cycle length and the share of it that is night. The runtime simulation integrates a cycle to give fuel per hour and battery survival, but the cycle comes from the client scene's TOD settings, which the dedicated server assembly does not carry, so the builder uses adjustable inputs (60 minutes, one quarter night) and never presents them as fact.
To settle it: Read the TOD_Time and TOD_Sky settings from the client scene bundle and confirm the night share against a logged in game clock.
Client data: build 25129251, captured 7 Sept 2026. Sources and dates.
How these values were sourced
Generator and battery values come from the game's prefabs; what each device draws comes from the shipped server assembly, which is a different build. Both are stamped rather than blended. Socket names are printed as the prefabs carry them, which assumes the client does not localise the wire tool's slot names. A modded server can change response times and power rules.
