Belt, Power & Battery Calculator

Base values only, before upgrade research is applied.

Belt sizing

How many conveyor belts carry a target item rate?

300 items/min range 30 to 1200
Required belt tier Tier 3
Tier speed 300 items/min
Belt build cost each 1750

Tier 5 carries 600 items/min. Rate the whole line to the slowest belt in it.

Power supply sizing

How many generators cover a target draw?

150 MW range 10 to 1200
Units required 5
Delivered peak 150 MW
CPU effect --

Solar panels only generate during daylight, so a solar-only grid also needs storage sized to the night.

Battery discharge sizing

How many Battery modules keep a steady draw inside the per-module discharge cap? One Battery outputs at a maximum of 10 MW, so draws above that need parallel modules.

10 MW range 1 to 60 (single battery limit is 10 MW discharge)
Battery modules needed 1
Combined discharge ceiling 10 MW
Charge ceiling 50 MW max input

At 10 MW steady draw, a single Battery module sits exactly at its 10 MW discharge cap, so one module is enough. Add one module per another 10 MW of draw.

Refinery line sizing

How many Single Regolith Refineries are needed to feed a target oxide output? Numbers are base production at 100 percent richness of the chosen oxide.

20 oxide/min range 4 to 200
Refineries needed 1
Combined oxide output 20 oxide/min
Combined slag output 20 slag/min
Power draw (6 MW each) 6 MW

Each Single Refinery produces 20 oxide per minute at 100 percent richness. At default 20 percent silicon richness, the refinery yields 1.6 silicon oxide and 6 slag for every 20 regolith; that ratio is what the Single Regolith Refinery actually delivers and is not recalculated by this tool.

What this tool does not do: the game's lunar night length is not published by the developer, and no base-level power draw figure is published either, so this page does not compute a night storage requirement. Anything that multiplies your draw by a night duration would be inventing a number.

Belt speeds 60 / 150 / 300 / 450 / 600 items per minute, generator peaks 30 / 75 / 300 / 90 / 16 / 600, Battery capacity 100,000 units with a 10 MW discharge cap, and Single Refinery base production 20 reg -> 20 oxide + 20 slag at 100 percent richness are base values. Upgrade research and the Multi-Regolith Refinery's doubled output change these values.

Logistics & Power FAQs

How many conveyor belt tiers are in The Crust? +

There are 5 tiers. Tier 1 moves 60 items per minute, Tier 2 moves 150, Tier 3 moves 300, Tier 4 moves 450 and Tier 5 moves 600. Building costs rise from 250 for Tier 1 to 7750 for Tier 5. An Underground Conveyor has no speed of its own and runs at the lower speed of whatever tiers you connect to its two sides.

Why does a solar grid still need batteries in The Crust? +

Solar panels only generate during daylight, so anything that must run through the night needs either stored power or a generator that ignores the daylight cycle. Fuel Generator, RTG and Fusion Reactor all fall into that second group. The length of the in-game night is not published by the developer or documented on the community wiki, so this page does not convert your power draw into a storage figure.

How many Battery modules do I need for a steady draw? +

The community wiki documents a Battery capacity of 100,000 units, a discharge cap of 10 MW and a charge cap of 50 MW. The wiki publishes no time basis (watt-hours) for that capacity, so this calculator does not convert it into an hours-of-runtime figure. It sizes module count by the discharge ceiling instead: one module per 10 MW of steady draw.

How much power does a Fusion Reactor produce? +

The community wiki lists a peak output of 600, the highest of any power source it documents, and describes it as running on energy cells based on Helium-3. The same wiki page notes a CPU value of negative 25, meaning it offsets CPU cost rather than consuming it.

How many Single Regolith Refineries do I need? +

At 100 percent richness of the chosen oxide, each Single Regolith Refinery consumes 20 regolith per minute and produces 20 oxide per minute plus 20 slag per minute, drawing 6 MW. A 60 oxide/min line needs 3 refineries and 18 MW. The wiki flags that the Multi-Regolith Refinery's doubled-output column may be bugged, so this tool sizes against the Single Refinery base.

Which power source should I pick for a fixed draw? +

Divide your draw by the peak output of the source and round up. A 150 MW base is covered by one Large Solar Panel at 300, or one Fusion Reactor at 600, or two Fuel Generators at 90 each. Solar also needs storage for the night, while the other two do not.
