What is a Satisfactory Power Calculator?

A satisfactory power calculator is an essential tool for players of the factory-building game Satisfactory. It allows you to accurately predict the total power output (in Megawatts, or MW) of your power grid based on the number and type of generators you have, as well as their clock speed. Managing power is critical; as your factory expands, its power consumption grows, and an unexpected power trip can halt your entire production line, causing a catastrophic failure cascade. This calculator helps you plan for expansion and ensure your power production always exceeds consumption.

This tool is for any FICSIT pioneer, from those setting up their first coal power plant to engineers designing massive nuclear facilities. By understanding your potential power generation, you can make informed decisions about overclocking, resource allocation, and when to invest in the next tier of power technology. A reliable power grid is the foundation of every successful factory, a concept you can explore further with this {related_keywords} guide.

The Satisfactory Power Calculator Formula

Power generation in Satisfactory doesn’t scale linearly with clock speed. Instead, it follows a polynomial curve. The satisfactory power calculator uses this specific formula to provide accurate results. When you set a generator’s clock speed (C) above or below 100%, its power output (P) and fuel consumption (F) are affected differently.

Power Output Formula: P = P_base * (C / 100) ^ 1.321928

Fuel Consumption Formula: F = F_base * (C / 100)

This means overclocking provides diminishing returns for power output relative to the fuel it consumes. For example, at 200% clock speed, a generator consumes 200% of the fuel but produces roughly 250% of the power. This calculator handles these non-linear calculations for you.

Variables Table

Variable	Meaning	Unit	Typical Range
P_base	The base power output of a single generator at 100% clock.	MW (Megawatts)	75 – 2,500
C	The clock speed you set on the generator.	% (Percentage)	1 – 250
F_base	The base resource consumption of a generator at 100% clock.	Items/minute	4.8 – 100

Practical Examples

Example 1: Early-Game Coal Power Setup

You are setting up your first major power plant to move away from biomass burners. You have a pure coal node providing 120 coal/minute.

• Inputs:
  • Generator Type: Coal Generator
  • Number of Generators: 8
  • Clock Speed: 100%
• Results:
  • Total Power Production: 600 MW
  • Total Coal Consumption: 120/min (8 generators * 15 coal/min)
  • Total Water Consumption: 360/min (8 generators * 45 water/min)
• Analysis: This setup perfectly uses the 120 coal/min from the miner, providing a stable 600 MW grid to power your early-to-mid-game factory. This is a common milestone for many players, and our {related_keywords} article can help you optimize it.

Example 2: Overclocked Fuel Power Plant

You have unlocked fuel power and want to maximize output from a limited number of Fuel Generators to save space. You decide to overclock them using Power Shards.

• Inputs:
  • Generator Type: Fuel Generator
  • Number of Generators: 10
  • Clock Speed: 250%
• Results:
  • Total Power Production: ~3,763 MW
  • Total Fuel Consumption: 300/min (10 generators * 12 fuel/min * 2.5)
  • Power per Generator: ~376.3 MW
• Analysis: By overclocking 10 generators to the maximum, you get the power equivalent of roughly 25 generators running at 100% clock speed. However, this comes at a higher fuel cost per MW generated, making it a trade-off between space efficiency and resource efficiency.

How to Use This Satisfactory Power Calculator

Using our tool is straightforward. Follow these steps to accurately calculate your power generation potential:

1. Select Generator Type: Choose the power generator you plan to use from the dropdown menu (e.g., Coal Generator, Nuclear Power Plant). The calculator will automatically load the base stats for that generator.
2. Enter the Number of Generators: Input how many generators of that type are in your power plant.
3. Set the Clock Speed: Enter the desired clock speed as a percentage. 100% is the default. To overclock, enter a value up to 250%. To underclock, enter a value below 100%.
4. Review the Results: The calculator instantly updates. The primary result shows your total power production in MW. The intermediate values show power per generator and the total resources required to sustain the plant.
5. Analyze Consumption: Use the “Resource Consumption Breakdown” table to ensure your miners and belts can supply the necessary resources per minute. This is a crucial step detailed in our {related_keywords} post.

Key Factors That Affect Power Production

Several factors beyond the calculator can impact your grid’s stability. Being a successful pioneer requires a holistic approach to your power infrastructure. Thinking about these factors is a key part of using a satisfactory power calculator effectively.

1. Resource Supply Chain: Your power plant is only as reliable as its fuel source. A single stalled belt or backed-up pipe can shut everything down. Always ensure your mining, transport, and fluid systems can consistently exceed the plant’s demand.
2. Power Storage: Power Storages (batteries) are vital. They absorb excess power when production is high and release it during consumption spikes, preventing your grid from tripping. They are essential for stabilizing grids that rely on fluctuating sources like Geothermal Generators.
3. Grid Segmentation: Using Power Switches allows you to create independent power grids. This is useful for isolating critical infrastructure (like your water extractors and miners for a coal plant) from your main factory. If the factory grid fails, the power plant’s own systems remain online, making it easier to restart.
4. Consumption Spikes: Machines don’t draw power continuously. They draw a large amount when they start a production cycle. A factory with many machines starting at once can create a massive power spike that exceeds your production capacity, causing a trip. Over-provisioning power or using batteries helps mitigate this. If you are interested in this topic, check our guide on {related_keywords}.
5. Head Lift (for fluids): For power plants that require water or other fluids, ensuring you have enough head lift is non-negotiable. If your pipes go too high without a pump, the fluid flow will stop, starving your generators.
6. Power Shards: These are used for overclocking. Your ability to find and collect Power Shards in the world directly limits how much you can boost your power production beyond its base limits.

Frequently Asked Questions (FAQ)

1. Why is the power formula not linear?

The developers designed the overclocking formula to reward players for building more machines rather than simply overclocking a few. The exponential power curve makes overclocking efficient for space, but less efficient for resources, creating an interesting strategic choice.

2. What happens if I don’t provide enough fuel or water?

If a generator’s input buffer for fuel or water runs empty, it will shut down. This reduces your total power production. If enough generators shut down and your grid’s consumption exceeds production, the entire grid will trip and all machines will lose power.

3. Should I overclock or underclock my generators?

Overclocking is great for maximizing power in a small area but costs more resources per megawatt. Underclocking is extremely resource-efficient. A generator at 50% clock uses 50% fuel but produces ~65% of its base power, stretching your fuel reserves significantly. This is great for early-game biomass burners.

4. Does this calculator account for Power Storages (Batteries)?

No, this satisfactory power calculator focuses on your grid’s production capacity (MW). Power Storages add energy capacity (MWh) and help manage spikes, but they do not generate new power themselves.

5. How accurate are the numbers in this calculator?

The calculations are based on the official formulas from the game’s wiki and extensive community testing. They are highly accurate for the current version of the game.

6. Why is my Geothermal Generator output fluctuating?

Geothermal Generators are placed on geysers, which have varying purity (Impure, Normal, Pure). The output of a generator can fluctuate between a minimum and maximum value over a cycle. This calculator shows the average output based on the geyser’s purity setting.

7. How do I handle Nuclear Waste?

This calculator does not model waste output. Nuclear power produces waste that must be processed and stored long-term. Failing to manage waste will cause your Nuclear Power Plants to shut down. Plan your waste management system before building nuclear. A key resource is our {related_keywords} article.

8. Can I input my factory’s power consumption?

Currently, this tool is designed as a production calculator. To find your consumption, check a Power Pole in-game to see the real-time graph. The goal is to use this calculator to ensure your “Capacity” line is always above your “Consumption” line.
