'''EU/t''' is a unit describing an amount of EU produced, moved, or consumed in a tick.
 
=== Quick Tip ===
GregTech's power system is called the '''GT Enet API''' (Enet).
 
== TL;DR ==
* If you have X generators of [[Tier]] Y, use cables that can handle X Amperes of Tier Y.
 
== Voltage and Amperage ==
'''Voltages''' describe certain constants which are EU limits, and determine the Voltage [[Tier|Tiers]].
 
'''Amps''' are packets, packages, or containers of EU. Amps are also often labeled with a voltage, to indicate how much EU they carry. A label indicates the amp holds anywhere from 1 more than the previous tier's EU limit to this tier's EU limit. For example, 1 LV Amp carries 9-32 EU (often 1-32 as ULV machines don't exist), and 1 MV Amp carries 33-128 EU.
 
=== Voltage Tiers ===
''Main Article: [[TiersTier]]''
<!--GregTech: New Horizons has 9 finished Voltage Tiers as of version 2.0.2.5, it also has 3 Voltage Tier partial finished voltage levels(*) and 4 not reachable voltage levels(**).-->
 
GregTech tiers its progression by different voltages. The voltage of a [[Generator|Generators]] (or for a multiblock generator, its [[Dynamo Hatch]]) determines the maximum amount of EU it will generate and put in each generated amp. '''The voltage of a singleblock machine or [[Energy Hatch]] determines the maximum amount of EU that can be present in any drawn amp before the machine explodes.''' If a recipe's EU/t usage exceeds a machine's voltage EU limits (or if the recipe allows for drawing additional amps, when the recipe's voltage or EU/t usage per amp exceeds that limit), it will not attempt to process the recipe; the minimum voltage tier machine to process that recipe is listed next to the usage or voltage in [[NEI]].
 
The EU Limit of each subsequent tier is usually 4 times the previous.
 
Note: When used as numbers in calculations, ULV Tier counts as Tier 0, LV Tier counts as Tier 1, and so on.

=== Amperage ===
Amps are pushed, not pulled. "Drawn" is synonymous with "accepted" here.
 
Machines and energy hatches can only draw amps in full to fill their internal EU buffers. The capacity of the internal buffer is listed as "Capacity:" in the machine's or hatch's tooltip. When processing a recipe, a machine will draw from its internal buffer. The current contents of the internal buffer can be checked with the [[Portable Scanner]].
 
The maximum amount of amps a machine can draw is either listed on its tooltip or recipe-dependent. The minimum amperage of a recipe can be found in [[NEI]]. If no amperage is listed, the recipe's minimum amperage is 1. A machine can draw atup mostto a maximum of <math>\frac{2 \times \text{Recipe Usage EU/t}}{\text{Voltage Tier EU Limit}} + 1</math> moreamps ampto thanfill its internal buffer. This means that if the amperagemachine ofisn't processing a recipe, it will draw 1 amp to refill the internal buffer.
 
Several common amperages of GregTech machines can be found in the table below. "Drawing" means "draws up to", unless otherwise stated.
 
Output amps contain the maximum EU for the outputting machine's voltage tier.

== Overclocking ==
''Main Article: [[Overclock]]''
 
Machines of higher tiers can receive overclocks to speed up their recipes.

==Cables and Loss== <!--T:13-->
''Main Article: [[Cable]]''
 
GregTech EU can be transferred using GregTech [[Cables]].
 
Rather than priority by destination, power priority is given by cardinal direction. Cables will push power in the following priority:
<!--T:15-->
 
# Down
# Up
# North
# South
# West
# East
 
When producing power, each generator will always attempt to empty all of its internal buffer at once. This can cause one generator in a cable network to use fuel more rapidly than another, with order depending on tile entity processing and changing on chunk reloads.<!--T:15-->
 
All GT Cables have a max Voltage, max Amperage and a Loss/Meter/Ampere, indicated on their tooltip:
*'''Cables which receive amps containing more EU than their maximum Voltage will catch fire and melt.'''

== Multi-Amp Generation ==
''Main Article: [[Dynamo Hatch]]''
 
[[Multiblock]] Generators use [[Dynamo Hatch|Dynamo Hatches]] to output power. These come in 1A, 4A, 16A, and 64A variants. These generators will always attempt to fill existing generated amps with EU before generating more amps.
 
Line 387 ⟶ 401:
<!--T:21-->
{{Cleanup|Verify this loss mechanic still exists in 2.6.1}}
'''Any GT Block outputting EU has an energy loss on output.''' This means there is no such thing as lossless power transfer. A power outputting singleblock will take <math>8\times4^{tier}+2^{max(0, tier-1)}</math> EU from its internal buffer and output <math>8\times4^{tier}</math> EU (which is always the maximum EU one amp of that voltage tier can hold). For example, a [[LV]] [[Combustion Generator]] draws 33 EU from its internal buffer to generate 1 amp holding 32 EU. The energy lost is therefore <math>2^{max(0, tier-1)}</math>. ULV is an exception, having the same loss value as LV, i.e. 1 EU.

== Transformers ==
[[File:Gregtech_Machines_Transformer.jpg|right|thumb|Picture of a Transformer in default mode transferring 1 amp of HV into 4 amps of MV.]]
 
''Main Article: [[Transformer]]''
 
Transformers convert EU between voltage tiers. In Step Up mode, they draw up to 4 amps of a lower voltage to fill their internal buffers, and draw from their internal buffers to produce 1A of a higher voltage. This can allow lower tier amps to power higher tier machines which may only draw 1-2 A for a recipe. Similarly, in Step Down mode, they draw 1 amp of a higher voltage to fill their internal buffers, and draw from their internal buffers to produce up to 4A of a lower voltage. This allows use of higher tier power generators with lower tier machines while preventing explosions. Use a [[GT Tools#Soft Mallet|Soft Mallet]] to switch the mode.
 
The big dot with a plus is the high voltage side and is the front face, while the five smaller circles are the lower voltage sides. Regardless of mode, the big dot is ''*always*'' for the higher voltage. That means in Step Up mode, transformers have one output, five inputs, and in Step Down mode, they have five outputs, one input.
 
The output loss section above applies to transformer outputs as well.

==Trivia==
* GregTech's power system is called the '''GT Enet API''' (Enet).
* Since version 5.0 (for Minecraft 1.7.2), GregTech has its own Energy System since [[GregoriusT]] wasn't satisfied with [[IC2 Experimental]]'s Energy System.
 
{{Quotation|The reasons of why I removed compatibility to the IC² Enet are that Cable Loss doesn't work, that the Network doesn't have Packets anymore and that it switched from Integer to Double (what is horrible for larger Energy Storages). Not to mention that it is very hard to have control over Energy flow without constantly registering and unregistering TileEntities.|GregoriusT}}
