'''Power Generation''' is a core concept of the modpack, necessary at every [[tier]] beyond the [[Stone Age]]. There are many different
== Steam ==
[[Steam Age|Steam]] is the first power source you have access to, and is the fuel for the first Bronze and Steel machines. Upon reaching LV, it is also the starter fuel for generating EU, but it falls off in the next two tiers due to how difficult it becomes to transport a lot of Steam around to match the EU/t demands of your upgraded machines, especially your Electric Blast Furnace.
Production: Steam is produced in
The first set of boilers available are the Small Boilers. All of these are available in the Bronze age, and are the backbone of your first machines. Included in this lineup are the [[Small Coal Boiler]], the [[High Pressure Coal Boiler]], the [[Simple Solar Boiler]], [[High Pressure Solar Boiler]] and the [[High Pressure Lava Boiler]].
* The Small Coal Boiler is the first boiler available, consuming coal or charcoal, and is not really viable for power production, giving a measly 120 L/s of steam, or 3 EU/t of power, or even less with efficiency losses from turbines if converting into [[Electricity]].
* The High Pressure Coal Boiler produces 300 L/s of steam, a much better number, but still only equivalent to 7.5 EU/t. Like the Small Coal Boilers, these run off coal or charcoal.
* The Simple Solar Boiler produces the same amount of steam as a Small Coal Boiler, but runs off sunlight
* The High Pressure Solar Boiler is an upgraded version of the Simple Solar, producing 360L/s at full power. It calcifies in the same way, but will never go below 120L/s. It can be restored to full capacity by breaking and replacing when it starts to lose production.
* The High Pressure Lava Boiler produces 600 L/s of steam, or 15 EU/t, and run off lava. These require a constant source of lava, which is generally not something available at LV, so these are not recommended for use in constant power generation. They have a multiblock upgrade in EV tier, the Large Heat Exchanger, which proves a lot more useful.
GT++ adds Advanced Boilers, which are
Next are the [[Railcraft
Finally, there are the multiblock Large Boilers from GregTech. The first one, the Large Bronze Boiler, is available at late LV (as soon as you have MV circuits), with an upgrade in the following tier, the Large Steel Boiler. These run off (extremely large quantities of) any furnace fuel or flammable liquid. Running these off liquids is not really viable- Railcraft boilers run off creosote more efficiently, while most any other flammable liquid is better in a generator of some kind. These produce enormous amounts of Steam, 16000L/s (400 EU/t) for a Bronze and 1000 EU/t for a Steel Boiler. They also consume extremely large quantities of fuel, so it's important to automate the inputs from the start. They're extremely good for consuming solid fuel, but Railcraft Boilers are more efficient for using Creosote.
Obtaining Fuel: Boilers require fuel to run, the two most common being
In later tiers, large quantities of Steam or, more specifically, Superheated Steam can be produced by the use a [[Large
Used in: [[Steam
== Oil ==
[[Oil]] is the most common fuel used LV-HV. It's available mid-LV, and is viable until
Production: Oil is pumped out of the ground through either pumps on physical oil wells, or oil drilling rigs on bedrock. It is then refined through a process of distillation and refining into four "base" fuels. From there, these base fuels can be cracked, distilled, refined, and mixed into various more complex hydrocarbons or burned directly.
Line 40 ⟶ 41:
Distillation and refining: Oil can then be distilled into four primary distillates, in various fractions based on what type of oil it is. A distillery lets you pick one of the four fractions, while a distillation tower creates all four at once. Once the oil has been turned into a fraction, the fraction must be de-sulfurized by mixing it with hydrogen(can be easily obtained by electrolyzing water) in a chemical reactor. The four fractions are light fuel, heavy fuel, naphtha, and refinery gas. Until you obtain a distillation tower, the only two you need to worry about for power generation are light fuel and heavy fuel.
Tiers of Fuel:
* Light fuel is available at LV as a direct product of oil desulfurization.
Each tier is more complex than the last, but more oil-efficient. Light fuel is still a viable source of power even at EV, but at that point making cetane-boosted diesel will double your power output per cell.▼
* Diesel is available at MV from mixing light fuel and heavy fuel in a 5:1 ratio.
* CBD (cetane boosted diesel) is available at HV from mixing diesel with tetranitromethane (made using nitric acid and ethenone in a chemical reactor).
* HOG (high-octane gasoline) is available at HV in a large chemical reactor with EV power from an extremely complex set of recipes (regular gasoline can be made at HV but isn't worth using). It is not a direct upgrade from CBD, rather it gets it's own processing chain.
▲Each tier is more complex than the last, but more oil-efficient. Light fuel is still a viable source of power even at EV, but at that point making cetane-boosted diesel will
Once you obtain a distillation tower, the naphtha and refinery gas can be steam-cracked or hydro-cracked to obtain more light fuel or heavy fuel, or made into various chemicals for use in other applications.
CBD can be used until LuV, but a significant amount of large combustion engines need to be built to use CBD beyond IV. Note that only HOG can be burned in the ECE (extreme combustion engine, the IV multiblock combustion generator that produces 1A of LuV when boosted), which allows oil to be used until late LuV/early ZPM.
Used in: [[Combustion generators]]▼
== Bio Diesel ==
Line 62 ⟶ 70:
These 3 ingredients are then mixed together in a chemical reactor. From there, it can be burned directly or, once HV is reached, mixed with tetranitromethane(nitric acid and ethenone in a chemical reactor) to get cetane-boosted diesel.
Used in: [[Combustion
== Benzene ==
Benzene is another renewable fuel, made from charcoal and wood tar in a pyrolyse oven and later in a ICO (Industrial Coke Oven). It is fairly simple to make, but requires several fluid extractors to run at max speed. It is first available at MV, requiring an MV distillery to obtain it from Wood Tar, and it gets significantly stronger in EV when ICO and multiblock turbines become available. Benzene is viable until LuV+ (you can even use it all the way to UHV if you spam enough XL turbines, but with regular turbines you should plan to switch to fusion as soon as possible).
Warning: XL Gas turbine no longer accepts benzene in the latest stables (2.4.0+). The latest version that is confirmed not to contain this change is 2.3.3.
Benzene is first made in MV through a Pyrolyse Oven or Advanced Coke Oven. Set the Pyrolyse to create Wood Tar and Charcoal, if using it, send all the outgoing Charcoal to Fluid Extractors to be made into more Wood Tar, then send all of that into an MV Distillery to be made into Benzene. After having reached HV, the Distillery can be replaced with a Distillation Tower, which outputs Toluene, Phenol, Dimethylbenzene and Creosote alongside the Benzene. The first two are good fuels as well, alongside being useful for other chemistry.▼
▲
Nitrobenzene is a upgrade from benzene and can be produced in a gt++ chemical plant (there is a recipe in the large chemical reactor but it should not be used if nitrobenzene is for powergen). In comparison to benzene it can be used in XL Gas turbines, making it a direct upgrade to benzene power when moving from regualr gas turbines to XLGTs in IV. Currently (up to 2.6.0), the nitrobenzene is by far the strongest power source in the IV-ZPM ages.
Used in: [[Gas turbines]]
== Solar Panels ==
Solar panels are available in
Production: Solars up to ULV are crafted
Usage: Solar panels can be placed as a cover on a GT machine, battery buffer, machine hull or even cable, or crafted into a standalone solar panel block. Cover-type solars need periodic cleaning by right-clicking with empty hand while having a bucket of water in your inventory (can be done by golems), or their output will decrease. Solar panel blocks lack this disadvantage, also you don't need to protect them from rain.
Thaumcraft offers an option to make compressed solar panels. These take 8 panels of the previous tier to produce 10 times more power, so even if recipes become exponentially more expensive there's a bit of advantage. Octuple compressed solar panels can produce 100,000,000 EU/t, which is almost 200 times more than a UV solar panel. Moreover, there are infused versions of compressed solars which produce even more power under certain conditions. For example, octuple aqua infused solar can produce up to 600,000,000 EU/t while in thunderstorm. These also have the added bonus of being very TPS efficient, which is very important late game.
== Magic generators ==
▲Production: Solars are crafted first in the regular crafting grid, then in the Avaritia Dire Crafting Table. Panels are quite expensive to make up for not needing fuel.
Similar to Solar Panels are the Magic Energy absorbers, which can generate power from LV to EV passively, using energized nodes or a dragon egg placed on top of it. It is fairly expensive compared to non-passive EV generators, but considerably cheaper than EV solars, so it can be a good solution for powering multiblock miners, farms, etc in the midgame.
Magic energy converters consume various resources, and make up to one HV ampere. They can power farms that produce those very resources, for example 4 master magic energy converters can supply 1 amp of EV power to an [[Extreme Extermination Chamber | EEC]] that makes forbidden magic shards among other things.
[[Large Essentia Generator]] is a magical multiblock that consumes different essentias to produce EU. This is a WIP and a subject to change, though if you have decent progress in Thaumcraft, it can be a viable power source up to UV.
== Nuclear Reactors ==
They're available starting in EV, and are pretty good. See the [[Nuclear Reactors]] page for details.
== Large Heat Exchanger / WWXL / Extreme Heat Exchanger ==
These multiblocks all produce steam by consuming some kind of hot liquid. They typically work as a middle step between nuclear or [[Fusion Reactor | fusion reactors]] and [[Steam Turbine | steam turbines]] to produce even more power at the cost of more processing steps. All heat exchangers blow up if not properly supplied with water or distilled water.
* [[Large Heat Exchanger]] consumes hot coolant, lava or solar salt (hot) to convert distilled water into steam or superheated steam. It also returns the cold version of respective coolant. For example, lava is converted into pahoehoe lava which can be centrifuged for some basic resources: copper, tin, silver, aluminium, phosphorus, titanium and tungsten (though not very much and requires quite a bit of power).
* Whakawhiti Wera XL acts like 16 Large Heat Exchangers in one, and can only process lava and hot coolant
* Extreme Heat Exchanger can either act like basically 10 Large Heat Exchangers, but its main purpose is to create supercritical steam from plasma. It will only generate supercritical steam from plasma, not lava or hot coolant, and it is the only source of supercritical steam.
* Thermal Boiler can consume lava, pahoehoe lava or solar salt (hot) and makes either superheated or regular steam. It isn't known for high throughput rate but is quite cheap and can return small amounts of rare materials from lavas without centrifuging, among them: gold, silver, tantalum and tungstate.
Large Steam Turbines consume steam and return distilled water, Large HP Steam Turbines consume superheated steam and return steam, and Large SC Steam Turbines consume supercritical steam and also return steam.
Hot coolant basically comes from nukes (it can also come from Deep Earth Heating Pumps, Bees, and a few other sources, but these are all hilariously unviable).
Lava can be made from some bees or by pumping the nether, but in the quantities you need it, Everburn Urns or the Blood Magic Serenade of the Nether are preferred.
Plasma comes mainly from fusion reactors (there are some exceptions like Hydrogen Plasma from the Cyclotron but these are not really relevant for power gen).
Finally the solar salt (hot) comes from the Solar Tower. Its not a mainstream power source due to its high price in materials and relative setup complexity.

== Enriched Naquadah/Naquadria Reactors ==
Multiblock naquadah reactor, while also being called naquadah reactor, is completely different from singleblock ones. They consume nuclear based fuels for breeding and naquadah based fuels for power generation. There are five tiers of naquadah fuel, with the MK1 and MK2 fuels made in fusion reactor and chemical reactor and available in UV. Naquadah fuels starting from MK3 are made in the naquadah fuel refinery, a multiblock available in UHV. Naquadah reactor also consumes liquid air and accepts coolants and excited liquids to boost output. Coolants boost efficiency (extra power output without extra fuel) and available ones are IC2 coolant: 105% efficiency, super coolant: 150% efficiency, Cryotheum: 275%. In practice, cryotheum should be used. Excited liquids boost fuel consumption (and provide extra power output) and available ones are molten caesium: 2x, molten U-235: 3x, molten naquadah: 4x, molten atomic separation catalyst: 16x.
Naquadah reactors are considered to be weaker than plasmas turbines, but this might change with future rebalances.
== Fusion and Plasma ==
Fusion is unlocked in late LuV, opening the gate to ZPM and also to very powerful power generation. The Fusion Reactor is needed to create some new materials, but the plasma itself can give out a lot of EU if processed in the right machines. Not all the outputs of the reactor are plasmas, but the ones that are can all be used to generate power. Fusion reactors have unique 2/2 overclocks per tier.
The reactor itself needs a large, initial EU input to start working, and then needs additional energy while it processes the inputs into the outputs. If it ever stops, it will need the initial EU again to resume working. After getting it to work, the plasma can be moved into one of several machines.
Plasmas that are commonly used for power generation are helium and tin plasma. Helium plasma produces 2,560,000 EU/t on a MK3 reactor (before turbine and EHE efficiency) and is generally preferred due to the source materials (Helium-3 and Deterium) being easily obtainable. Tin plasma produces 5,480,928 EU/t on a MK3 reactor and has the advantage of higher energy output and higher energy density (which is proportional to the maximum processing capability of EHE).
Warning: XL Plasma turbine is changed significantly in the current dev version, with harsh penalties being applied to plasmas with low energy density that run through good turbine blades. The latest version that is confirmed not to contain this change is 2.3.3.
▲The reactor itself needs a large, initial EU input to start working, and then needs additional energy while it processes the inputs into the outputs. If it ever stops, it will need the initial EU again to resume working. After getting it to work, the plasma can be moved into one of several machines. The most popular one is the Large Plasma Turbine, which converts it directly to EU and also outputs the molten version of the material that the plasma was made of. Instead of this, the Extreme Heat Exchanger can also be used to generate Steam from the plasma, adding another step to the process but increasing the fuel efficiency.

▲The first tier solar requires 8 1 volt solars in the alchemist crafting table, second tier requires 8 single compressed, etc. Starting from triple onwards, it will require infusion. Read the [https://gtnh.miraheze.org/wiki/Infusion_Automation Infusion automation guide] for help on automating these solars. The maximum tier is 8 (Octuple), and requires 16777216 1 volt solars, which breaks down to [https://docs.google.com/spreadsheets/d/1E6J7cFoaiCGYgUb96yl7WkCTqdtDRGdOm-OTR4Zn3kA/edit#gid=157395997 this] in raw materials.
