'''Power''' is electrical energy that powers the operation of certain appliances, including workbenches, lights, temperature control devices, automated defenses, and more. Access to power is crucial to survival, especially in late game. The success of a colony often relies upon a fault-tolerant power grid with a reliable power flow that ensures that your appliances are working at all times, especially in emergencies.
+
'''Power''' is both the representation of [[Research#Electricity|electricity]] required to power a wide variety of appliances and buildings, and the name of a section of the architect that contains buildings that interact with this system.

=== Watermill generator ===
 
−
[[File:watermill_generator.png|64px|left|link=Watermill generator]] A [[watermill generator]] provides power from a moving river, providing a constant 1100W of power. It is relatively cheap and requires no upkeep, but is also fairly large and cannot be placed too closely to another without degrading performance. Requires research.

=== Ship reactor ===
 
−
[[File:ShipReactor.png|64px|left|link=Ship reactor]] Although it is a ship part and not listed in the ''Power'' menu, the [[ship reactor]] is perfectly usable as a power generator.  It provides 1000W of power, with no need for fuel or other maintenance; it does not generate any heat.  It is normally only built as part of the space ship to win the game, and must be powered up to become operational for the ship, which triggers a 15-day long enemy invasion event.  Requires research.

=== Vanometric power cell ===
 
−
[[File:Vanometric power cell.png|32px|left|link=Vanometric power cell]] Similar to the ship reactor, the [[vanometric power cell]] provides a consistent 1000W of power at all times with no upkeep or restrictions. It has a small 1x2 footprint and can be moved freely. The catch is that these power cells are very rare; they cannot be manufactured or purchased, only received as a quest reward. With their comparatively low output, there is no reliable way to acquire enough to satisfy more than a small fraction of a normal colony's power budget, but they are a convenient way of powering high-priority or off-grid equipment.

{{Royalty|no category}}
 
−
[[File:Unstablepc.png|32px|left|link=Unstable power cell]] Effectively a smaller, less powerful and significantly more explosive vanometric power cell from the [[Royalty DLC]]. It can only be captured from [[Mechanoid cluster]]s. It provides 400W with no need for fuel, in 1x1 footprint that can be moved around freely. While more common than the vanometric power cell, its fragility and explosive tendencies can make it hard to capture from clusters and care must be taken to shield it from damage when in use. It also only produces a relatively small amount of power, so like the vanometric power cell, it is most useful for off-grid or high priority items rather than supplementing the main power grid.

+
Power is measured in the form of '''Watts (W)'''. Power generators create watts, and appliances will consume a certain amount of watts to function. Most appliances will use power even when not actively being used - they must be manually switched off. Some appliances use less power when not in active use, sometimes referred to as "stand-by" power.

=== Waterproof conduit ===

Power conduits can randomly [[Events#Zzztt...|short circuit]] whenever they are powered, and many power buildings or appliances can also short circuit while in [[rain]] or [[snow]]. See [[Events#Zzztt...|Zzztt...]] for details.

== Power storage ==
+
Power travels through [[power conduit]]s, [[waterproof conduit]]s,  [[power switch]]es, [[batteries]], and all generators and generator equivalents. These power transporters must be directly adjacent to each other to connect and transport power between them. This is distinct from appliances, which do not transport power, but can connect to a power transport from up to 6 tiles away. See [[#Appliances|Appliances]] for more detail.

=== Storage ===
 +
{{Main|Battery}}
 +
Power is stored in the form of '''Watt-days (Wd)''', where 1 Watt-day can power a 1 W appliance for 24 hours. Each [[battery]] can store up to 600 Wd, but only store at 50% efficiency. This means that, for the purposes of ''storage'', 1 W for 24 hours would only give 0.5 Wd inside a battery. Batteries lose 5 Wd of stored power per day, even if they aren't connected to anything or are uninstalled in their minified state. The stored power is drawn from if, and only if, the current load wattage on the grid exceeds the current generation wattage. Power can be stored and drawn from at any rate - the 500 Wd generated by 1000 W power generator over the course of a day and stored in 50%-efficient batteries can be consumed in 6 hours if the connected grid is 2000W below demand or last for days if demand only exceeds supply by a few watts.

When placing an appliance's blueprint, the most direct connection point to a power transmitting structure will be displayed as a golden yellow connection between the current blueprint position and the power. Note that it will display a connection even if the grid it attaches too does not sufficient or any power, and that while an appliance will default to that connection point it will be able to connect to other sources with range using the reconnect gizmo mentioned below. If no yellow wire is shown, there is no connection point in range.

Once constructed, this connection will be displayed by a black "power cord" that runs from the connecting power transmitting building to the appliance in question. This cord is graphical only and cannot be interacted with or damaged in any way. Additionally, when viewing the power grid, a magenta wire similar to the yellow above will display the connection point of appliances in view.

=== Managing appliances ===
+
Selecting any power transporter or appliance attached to a grid will display the "Grid Excess/Stored" values in the info pane. If the demand for power exceeds the current supply and cannot be made up for by consuming stored power, appliances connected to the grid lose power until the supply is once again below demand. It is currently unknown how which appliance is disabled is selected - it may be random.

Enemy [[mechanoid]]s - that is, all mechanoids without any DLC - do not require any source of power. However, your [[allied mechanoid]]s do. When controlled by a colony, an active mechanoid's power need falls by 10% per day. Non-working mechs lose 3% power per day. They can enter a dormant self-charging state, which instead restores 1% power per day for free. Mechanoids in a [[caravan]] do not consume or gain any power.

A mechanoid's power need does not directly translate to electrical power. However, [[mech recharger]]s require a constant 200 W, [[large mech recharger]]s require 400 W, and both chargers restore 50% of any mechanoid's power per day. When recharging, mechanoids create [[Toxic wastepack]]s, which can lead to [[pollution]].

Power is both the representation of electricity required to power a wide variety of appliances and buildings, and the name of a section of the architect that contains buildings that interact with this system.

Power conduit Hidden conduit Waterproof conduit Power switch Wood-fired generator Chemfuel powered generator Wind turbine
Battery Solar generator Geothermal generator Watermill generator Toxifier generator Electroharvester Bioferrite generator

Mechanics[edit]

StumpChoppedA (cropped).png
This section is a stub. You can help RimWorld Wiki by expanding it. Reason: Does not cover the mechanics of power sufficiently - how is the order of power loss determined when demand>supply? When do power generators tick? When does battery capacity tick? etc..

Power is measured in the form of Watts (W). Power generators create watts, and appliances will consume a certain amount of watts to function. Most appliances will use power even when not actively being used - they must be manually switched off. Some appliances use less power when not in active use, sometimes referred to as "stand-by" power.

Power conduits can randomly short circuit whenever they are powered, and many power buildings or appliances can also short circuit while in rain or snow. See Zzztt... for details.

Transport[edit]

Power only exists within a power grid and requires something to transport it. Any power that isn't used or stored is wasted.

Power travels through power conduits, waterproof conduits, power switches, batteries, and all generators and generator equivalents. These power transporters must be directly adjacent to each other to connect and transport power between them. This is distinct from appliances, which do not transport power, but can connect to a power transport from up to 6 tiles away. See Appliances for more detail.

Configurations of connected power transporters are called grids. All points in a grid have instantaneous access to all power generated and stored by buildings attached to the grid. Grids that are not connected by power transporters, or only connected via a power switch that is turned off, are completely independent from each other.

Storage[edit]

Main article: Battery

Power is stored in the form of Watt-days (Wd), where 1 Watt-day can power a 1 W appliance for 24 hours. Each battery can store up to 600 Wd, but only store at 50% efficiency. This means that, for the purposes of storage, 1 W for 24 hours would only give 0.5 Wd inside a battery. Batteries lose 5 Wd of stored power per day, even if they aren't connected to anything or are uninstalled in their minified state. The stored power is drawn from if, and only if, the current load wattage on the grid exceeds the current generation wattage. Power can be stored and drawn from at any rate - the 500 Wd generated by 1000 W power generator over the course of a day and stored in 50%-efficient batteries can be consumed in 6 hours if the connected grid is 2000W below demand or last for days if demand only exceeds supply by a few watts.

Note: Image of the "power cord" connecting a constructed appliance to a conduit, image of the "yellow wire" showing a prospective connection point when placing a blueprint, image of the "pink wire" showing the actual connection points once built.
For a list of all buildings that consume power, see here

Appliances are structures or buildings that consume power but don't transmit it. Most appliances will connect automatically if placed up to six squares away from a power transporter, or when one is placed within range.

When placing an appliance's blueprint, the most direct connection point to a power transmitting structure will be displayed as a golden yellow connection between the current blueprint position and the power. Note that it will display a connection even if the grid it attaches too does not have sufficient or any power, and that while an appliance will default to that connection point it will be able to connect to other sources with range using the reconnect gizmo mentioned below. If no yellow wire is shown, there is no connection point in range.

Once constructed, this connection will be displayed by a black "power cord" that runs from the connecting power transmitting building to the appliance in question. This cord is graphical only and cannot be interacted with or damaged in any way. Additionally, when viewing the power grid, a magenta wire similar to the yellow above will display the connection point of appliances in view.

When connected to the power grid, it can take a few moments before an appliance turns on.

Selecting any power transporter or appliance attached to a grid will display the "Grid Excess/Stored" values in the info pane. If the demand for power exceeds the current supply and cannot be made up for by consuming stored power, appliances connected to the grid lose power until the supply is once again below demand. It is currently unknown how which appliance is disabled is selected - it may be random.

Managing appliances[edit]

Reconnect: Click to force an appliance to reconnect to a conduit line or power source. This can also be used to change which power source an appliance is connected to if there is more than one in range.
Designate toggle power: Click to mark an appliance to be turned on (✔) or off (X) by a colonist set to Basic.

Mechanoid power[edit]

This section relates to content added by Biotech (DLC). Please note that it will not be present without the DLC enabled.
Main article: Mechanoid creation

Enemy mechanoids - that is, all mechanoids without any DLC - do not require any source of power. However, your allied mechanoids do. When controlled by a colony, an active mechanoid's power need falls by 10% per day. Non-working mechs lose 3% power per day. They can enter a dormant self-charging state, which instead restores 1% power per day for free. Mechanoids in a caravan do not consume or gain any power.

A mechanoid's power need does not directly translate to electrical power. However, mech rechargers require a constant 200 W, large mech rechargers require 400 W, and both chargers restore 50% of any mechanoid's power per day. When recharging, mechanoids create Toxic wastepacks, which can lead to pollution.
