Satisfactory Fuel Generator Layout & Planning Guide

This guide explains how Fuel Generators work, how to calculate the fuel they need, how to size the refineries behind them, and how to lay the whole thing out so it keeps running without backing up or starving your grid. Everything here is written to be read alongside the calculators on this page, so you can move between theory and numbers as you plan.

What Is a Satisfactory Fuel Generator Layout?

A Fuel Generator layout is the physical arrangement of the machines that turn crude oil into electricity. It usually has four parts: the extraction stage that pulls crude oil out of the ground, the processing stage where refineries convert that oil into fuel, the transport stage where pipelines carry fuel to the power plant, and the generation stage where Fuel Generators burn that fuel and push power into your grid.

The "layout" part matters more than most players expect. A fuel chain that is calculated correctly but laid out badly still fails, because pipes have flow limits, because byproducts have nowhere to go, and because a hundred generators packed into one narrow row are painful to expand later. A good layout keeps each stage in its own lane, leaves room between rows for belts and pipes, and makes the direction of flow obvious at a glance.

Most players end up building one of three shapes. The first is a long row, where refineries sit at one end and generators stretch away in a line. The second is a grid, where generators are arranged in several rows fed by a shared fuel bus. The third is a satellite setup, where several small power plants are fed by separate refinery clusters. Each has trade-offs, and the layout planner on this page can generate all of them.

How to Calculate Fuel Generator Requirements

Fuel Generator math is simple arithmetic once you know the inputs. Three numbers matter: the number of generators, the clock speed of each generator, and the base fuel consumption of the fuel type you are burning.

The formula for total power is generator count multiplied by base power multiplied by clock speed as a decimal. At default values a Fuel Generator produces 150 MW, so twenty generators at 100% produce 3,000 MW, and the same twenty generators at 150% produce 4,500 MW.

The formula for fuel demand is generator count multiplied by base consumption multiplied by clock speed as a decimal. If a generator burns 12 m³/min of fuel at 100%, twenty generators need 240 m³/min, which is 14,400 m³ per hour. That hourly figure is useful because it lets you sanity-check your refinery output against a whole hour of runtime rather than a single minute.

The important thing to remember is that Fuel Generators scale linearly. Doubling the clock speed doubles the power and doubles the fuel use, so efficiency — measured as megawatts per unit of fuel — stays constant. This is different from production buildings, where overclocking costs disproportionately more power. If you are short on fuel, overclocking generators will not help you; it just makes them burn through the same fuel faster.

How Fuel Production Affects Power Generation

Your power plant is only as reliable as the fuel line feeding it. If refineries produce 200 fuel per minute and your generators want 240, the generators will run intermittently and your grid will flicker. If refineries produce 300 and your generators want 240, the surplus fuel backs up, refineries stall, and — critically — their byproducts stop flowing too.

The standard crude oil to fuel recipe is a good example. It converts 60 crude oil per minute into 40 fuel per minute while producing 30 polymer resin per minute as a byproduct. That resin has to go somewhere. If it does not, the refinery's output buffer fills and fuel production stops entirely. Many players who cannot work out why their power plant keeps stalling eventually discover the problem is a full resin container, not a fuel shortage.

Matching production to consumption is therefore a two-sided problem. You want enough refineries to cover the fuel demand, and you want a destination for every byproduct so nothing ever blocks. The Resource Requirement Calculator on this page lists both the inputs and the byproducts so you can plan the whole chain, not just the fuel.

How to Plan a Scalable Fuel Factory

Scalable fuel factories share a few habits. They separate the refinery block from the generator block with a clear transport corridor. They size the corridor for more pipes than they currently need. They keep generator rows short enough that you can extend the row rather than rebuild it. And they leave a wide margin of empty foundation around the whole plant.

A practical approach is to decide on a module size and then repeat it. For example, one refinery making 40 fuel per minute can support roughly three generators at 100%. Six refineries support eighteen generators, which is 2,700 MW. If you later need more power, you copy the module: another six refineries and another eighteen generators, fed by the same crude oil line if capacity allows.

Module-based planning also makes overclocking decisions easier. If your modules are sized for 100% clock, you always have the option of pushing a module to 150% later for a quick boost rather than building a whole new one. The Factory Ratio Calculator gives you the machine counts for a module at whatever clock speed you choose.

How to Optimize Generator Placement

Generator placement is mostly about pipe access and serviceability. Every generator needs a fuel input, and fluid pipes have a maximum flow rate, so generators are usually fed from a shared bus — a single pipe running along the row with short branches dropping into each machine. This is compact, easy to extend, and easy to debug because you can walk the bus and see where pressure drops.

Two rows of generators facing each other across a central bus is a popular arrangement. It halves the pipe length, keeps the build symmetrical, and leaves a clean walking corridor. Three or four rows fed from a single manifold also works, but at some point the manifold itself becomes the flow bottleneck and you need to split it into separate lines.

Leave at least one foundation of space between generators. Cramming them flush together makes it hard to reach a machine that has stopped, and it makes later expansion awkward. The layout planner's spacing control lets you experiment with different gaps before you commit to a build in game.

How to Avoid Fuel Production Bottlenecks

Bottlenecks in fuel chains almost always come from four places. The first is crude oil supply: if your extractors cannot feed every refinery, the refineries at the end of the line will idle. Check total extractor output against total refinery demand before building anything else.

The second is byproduct blockage. Polymer resin, heavy oil residue and other outputs must have a consumer, a storage buffer with headroom, or a sink. A sink is the simplest guaranteed solution when you are still figuring out what to do with the material.

The third is pipe throughput. A Mk.1 pipeline moves 300 m³/min. If your generators need 420 m³/min of fuel, one pipe is not enough no matter how well everything else is built. The Pipeline Planner calculates how many separate lines you need and how loaded each one will be.

The fourth is power draw from the fuel chain itself. Refineries and extractors consume power. On a large plant that consumption is significant, so the net power you actually gain is lower than the generator output. The dashboard and Power Calculator both show net figures so you are never caught out by a chain that produces 3,000 MW but consumes 500 of it.

How Overclocking Changes Factory Ratios

Overclocking changes two things at once: how much a machine produces, and how many machines you need. Running six refineries at 100% produces the same fuel as four refineries at 150%, but the four overclocked machines draw considerably more power each and need more space per machine for the same footprint of output. In practice, overclocking is most useful when space is tight, when you are short on building materials, or when you want to squeeze more output from an existing line without laying new foundations.

For Fuel Generators the calculation is clean: power and fuel both scale linearly, so a generator at 200% behaves exactly like two generators at 100% in terms of fuel per megawatt. There is no efficiency penalty and no efficiency bonus. Overclocking generators is therefore purely a space and building-count decision.

For refineries and blenders the story is different. Their power draw scales with clock speed raised to a power greater than one, so a refinery at 200% draws more than twice the power of one at 100% while producing exactly twice the output. The Overclock Calculator on this page shows both the output difference and the power difference, so you can see the real cost of pushing a machine harder.

How to Use the Fuel Generator Calculator

Start with the number of generators you want to build and set the clock speed. Choose your fuel type from the dropdown — the base consumption rate updates automatically, and you can override it if your game version uses a different value. Pick the recipe your refineries will run, then read the results panel.

The results show total power in both megawatts and gigawatts, fuel demand per minute and per hour, the exact refinery count and the number you actually need to build, the crude oil requirement, any water requirement, the byproduct rate, the power draw of the fuel chain itself, and the net power you gain. The status indicator below the results tells you at a glance whether the setup is balanced, whether you are short on fuel, or whether you have a resource bottleneck.

If you want to work in the opposite direction — starting from a power target rather than a generator count — use the Generator Count Calculator in the Advanced Tools section, or switch the Fuel Production Planner to "desired power output".

How to Use the Layout Planner

The layout planner turns your numbers into a diagram. Set the generator count, the number of rows, the refinery count, the pipeline side, the power output direction, and the spacing between machines. The canvas redraws immediately.

You can drag the canvas to pan, use the scroll wheel or the toolbar buttons to zoom, toggle the grid and labels, and reset the view at any time. Presets at the top of the section fill in sensible configurations for common generator counts and layout styles, from a compact ten-generator block to a hundred-generator multi-row plant.

When the layout looks right, export it as a PNG image for a build guide, as an SVG if you want a scalable file you can annotate, or print it directly. You can also save the configuration to your browser so you can come back to it later, or copy the configuration as text to share with other players. Nothing is uploaded anywhere: saving uses your browser's own local storage and stays on your device.

Working Out Your First Fuel Power Plant

If you are building your first fuel power plant, a reasonable starting target is 2,250 MW — fifteen Fuel Generators at 100% clock. That needs 180 fuel per minute, which is four and a half refineries on the standard recipe, so build five and let one run slightly underclocked. The crude oil demand is 270 m³/min, which is about two and a quarter oil extractors at standard output, so plan for three.

Lay the refineries in a block at one end of the site, run a fuel bus along the generator rows, and give the polymer resin a dedicated line to a sink or a storage container while you decide what to do with it. Once the plant is running and stable, you can duplicate the module when you need more power, and the ratio stays the same.

Why Net Power Matters More Than Gross Power

It is easy to look at a bank of generators, read the total output, and forget that the machines making the fuel are also eating into it. A refinery draws a meaningful amount of power, and so does an oil extractor. On a plant producing several gigawatts, the fuel chain itself can consume hundreds of megawatts.

Net power — generation minus fuel-chain consumption — is the number that actually tells you how much room you have for the rest of your factory. The dashboard shows it continuously, and the Power Calculator lets you add your entire factory's consumption on top to see whether you are running a surplus or heading for a brownout. Checking that number before you start building a new production line saves a lot of emergency troubleshooting later.
