Extreme Voltage (EV)

Extreme Voltage (EV) is the fourth electric tier in GregTech: New Horizons. In this tier, several mechanics are introduced such as Applied Energistics 2 (abbreviated as AE2) and the IndustrialCraft 2 Nuclear Reactors. This tier is largely centered around three big goals: starting an AE2 setup, traveling to Mars for new and important resources, and developing centralized electric infrastructure. It introduces several new multiblocks which greatly speed up many processes, but especially ore processing with the introduction of the Industrial Centrifuge, Industrial Maceration Stack, Ore Washing Plant, and others.

In the previous tier HV, the main goal was to be able to source titanium. This was done through conventional means such as building a T1 rocket and flying to the moon to collect ores, or other more esoteric means such as bees.

Having the ability to source and smelt titanium unlocks a wide range of new technologies. AE2 is introduced as a way to massively simplify your storage management and begin autocrafting. Note that most of the AE2 machines require titanium, so be prepared to mass produce titanium if you want to use AE2. The mechanics introduced by AE2 are incredibly important to the remainder of the game, so it's recommended to do some reading on best practices. See this subsection of the Automation article for additional information.

With the introduction of the Nuclear Reactor, it is possible to create reactors with designs that generate massive amounts of power on-tier. See the Nuclear Reactor's sample chart for more information. Other than the nuclear reactor, six new large engines become available as alternative means of power.

Lastly, an important note to keep in mind when entering this tier is that this is where many players get burnt out because of how difficult it is to get through this tier. Unlike the transition between the HV and MV tiers, EV is a big jump from HV to EV in terms of energy and resources needed. So be sure to build and prepare your automated systems (and mass-produce resources) if you haven't done so already, because manual crafting has likely become a very taxing task in this tier. You will want to overproduce resources and essential components such as titanium, steel, motors, etc., to make it easier and save time for you to make something you need rather than go back to mining after finding out you don't have enough resources repeatedly. Lastly, if you don't want to get burnt out and want to continue playing, do not rush into EV and the rest of the future tiers. Take your time.

Continued from the start of EV with a stack of titanium, you might want to increase your titanium production by chemical bathing ilmenite with sulfuric acid using an EV chemical bath, the resulting byproduct can be electrolysed to get the sulfuric acid back, forming a closed loop where the only input is crushed ilmenite ore. After getting a somewhat stable supply of titanium, you can actually start the EV tier.

You might've started epoxy and basic platline (platinum only); if not, start building as this is a good time to build it.

Tip: if you are using LCR for the platline, you can replace the need for centrifuge with it, which saves the cost of making an industrial centrifuge.

You might've found you are struggling to power up those EV single block machines with just several HV generators (either automated or not). If your main energy production is from oil, it's recommended to build a multiblock combustion engine and upgrade to cetane-boosted diesel if you didn't in HV. It costs about 4 stacks of titanium to make and without boosting with oxygen, produces 2048EU/t at 100% efficiency, and if boosted with oxygen, produces 6144EU/t at 150% efficiency. Because of the boosting mechanism, it's recommended to keep it boosting. It also requires a small amount of lubricant to run.

Another option is large gas turbine. It runs at efficiency based on the turbine you put into the controller. The gas input must be close to the optimal flow rate the turbine describes, or efficiency will drop. There is also a replacement, the oxidation fuel unit, where it's the same but does not need a turbine but needs oxygen to run but produces steam, but it's not recommended because it only produces 2048EU/t while costing more than the gas turbine. Also, its efficiency caps at 100% while large gas turbines are based on the turbine and can easily go beyond 100% efficiency.

If you want to make platline or got some platinum, you can build your first nuclear generator. You can check the Nuclear Reactor page to find what design that fits best for you. I recommend you to use the 1280EU/t design as it only needs 4 chambers (3 chambers for the main block). Build as many as you need as the reactor is pretty cheap in both maintaining and its build cost.

Radon is a new resource introduced in EV. There are 2 main ways to source radon in this tier. The first way is radium decay, which is extremely slow and requires sifting specific ores. The second is the radon loop, which needs Pu-239 which is somewhat time consuming to get in itself, and has a much higher setup cost, but is more permanent as your future radon is produced this way.

The radon loop is found as an LCR recipe that takes a Pu-239 ingot, Uranium 238 dust, and air and converts it into Pu-239 dust and radon. The Pu-239 dust can be smelted in any machine that does furnace recipes to recycle the Plutonium.

After finishing building those lines and you have increased your energy production, you can start to make nano circuits. You have to first upgrade your HV circuit assembler into an EV counterpart, and make nano CPU wafer. It's recommended to make it in LCR with a stable power supply because it needs 60 seconds to make one without overclocking. You will have to make 8 nano mainframes for the 2 EV field generators required for the tier 2 rocket computer.

You might've also noticed that EV field generator requires HSS-G. For getting tungsten, first collect a large amount of endstone, crush it and centrifuge the dust to get some tungstate dust, then make an EV autoclave for the first step of the tungsten line, separating lithium out of tungstate dust. Then, pass the liquid into chemical reactor with calcium chloride to make wolframite dust, then pass in hydrochloric acid to form tungsten hydroxide then process it twice in the EBF to get tungsten dust, or ingot if you want to pulverize it down into dust.

Then, blend tungsten dust with steel dust to get tungstensteel dust, and blend again with some miscellaneous dusts to get HSS-G dust. You have to make TPV coil upgrade for your EBF before processing HSS-G dust in it. Then cool it off using vacuum freezer to get the ingot. HSS-G is also used for the next tier of coils, but these are gated behind the IV assembler.

You can also start applied energistics with the supply of titanium. You have to make a controller, a drive, and a bunch of cables for your first network to get working, also ME crafting interface.

You might follow this instead: Applied Energistics 2

As you entered EV, you gained access to multiblock counterparts of centrifuge, thermal centrifuge, ore washer/chemical bath, and crusher. They are way more efficient compared to their singleblock variants, however they require large amounts of resources like Titanium and most are gated behind TPV coils, so they're listed here instead of in early EV. If your main resource income is from bees, centrifuge is recommended over all other multiblocks as it speeds up centrifuging combs significantly.

After getting the EV field generator you needed for the rocket computer, it's time to build your second rocket. It's a pretty straightforward step. If you forgot or didn't get much meteoric iron, you have to get back to the moon and mine some. I recommend you to have 12 stacks or 45 stacks if you don't want to go back to the moon again for meteoric iron (also for t3 rocket). With the exception of several new parts, which are booster and t2 landing module, the rest goes the same as t1 rocket but is more expensive.

You only need a trip to mars for you to get all the resources needed. Also, T2 lander doesn't need you to slow down when approaching as it's a balloon that bounces after it reaches the surface. Your mission there is to collect desh vein (it also has tungsten ore), tungsten vein (also provides lithium), and pitchblende vein (also provides thorium) if you didn't get enough uranium by centrifuging thorium ore. Remember to explore mars more for finding the mars dungeon which contains the T3 rocket blueprint.

After making power generation for EV, you found out that you are constantly wasting fuel because nuclear reactor / multiblock generators are constantly burning fuel. You will have to make a control system with a huge battery to efficiently use the generator.

You will be making a Lapotronic Supercapacitor for energy storage. Other types of energy storage, like single block storage, are not recommended due to their cost to store huge amounts of power. It will passively drain a trivial amount of energy (~30EU/t if 1x3x3 IV capacitor). You only need normal borosilicate glass to use IV and EV capacitor.

After a trip back to mars full of ores (and also loots), you should have enough tungsten to get ready for IV. Also, you can make EV superconductor. It's cheap enough in late-EV, with superior performance compared to other wires. You also have to get graphene. It needs tons of silicon due to the amount of wafer it requires to craft (32 for P-doped wafer, 8 for Nq-doped).

Good luck with your journey to IV!
