TPSServer: Conventional means of power generation

Hello, let’s have look into GT6 power generation we used in our server. As described in the ore processing post, main gameplay loop of GT6 revolves around processing ores. You go to get stuff and use it to make better stuff. Simple enough. There’s still one caveat that every player will have to face at some point: power consumption of the machines.

Power in GT6 comes at many forms: KU/t, RU/t, EU/t and so on. Getting electric power (EU/t) is not a magical click of a button that makes all problems go away- instead, it is a balancing act between supporting infrastructure (batteries, cabling and EU/t production) and consumption methods (EU/t to RU/t to run centrifuges, EU/t to KU/t for crusher machine…). It is generally good idea to move into electrical machines when you can, as they require less manual upkeep and logistics in the long run.

Where do you start? Steam power, of course! Make a Boiler, fill it with water, heat it up with Burning box and use the generated steam in Steam engine (KU/t output) or Steam turbine (RU/t output) to power your machines. Simple enough? Well…


And yes, we did it again

GT6 Bronze era steam machines are really powerful compared to manual crafting, but also very dangerous. Simple “I forgot that thing” may result you losing an hour of work, and good chunk of your base on top of that. Surrounding steam producers with blast-resistant materials is recommended.

After we got the initial ore and material processing going (Crusher, Sluice, Lathe, Compressor…) it was clear that the situation had to improved: it took considerable amount of time to baby-sit each boiler, keep the water flowing, clean the calcification and provide them with fuel. This would not last. And as it happened, one of us made an important discovery: “hey, theres diesel engines, lets try those”.

Diesel engines are such simple, elegant and easy-to-use power producing machines that I am convinced Greg must have added them into GT6 by accident. Just insert liquid fuel into it, point it towards RU/t consuming machine and leave it there. As an example, picture below has all things the Centrifuge requires to function (Diesel engine improved with Machine status display cover, adding On/Off -switch). Difference to steam setup is immense.

This is the future

  1. Ethanol

Now we have a working configuration that requires little upkeep, but nothing to fuel it! Steam is useless, Creosote oil does not work and Oil is nowhere to be found. What can be done here?

“hey look at ethanol, it should work”

We did, and discovered a way to generate Diesel engine -compatible fuel that is infinitely renewable, large in quantities, simple to make and easy to handle. Ethanol fueled our base all the way from late bronze era to LV Electric era. All of this was possible with little help from another great mod, Thaumcraft.

1.1 Ethanol raw materials: Potato farm

Creating Ethanol requires produce, and we decided to focus on single thing: delicious potatoes. One of our players was already skilled with Thaumcraft, and proposed usage of Clay + Wood Golems to harvest, re-plant and collect the potatoes in an automated farm. Following setup was used in MUCH larger scale out-of-picture, but only thing left now is the core farm located on the roof of Witch’s Hut.

Potato farm automation

Items are collected into single chest, after which the items are outputted into BC Transport pipes. After a quick sorting with a single diamond pipe, potatoes are send towards the distilling setup buffer chest.

1.2 Ethanol production

Producing Ethanol is a simple loop that fuels itself: Potatoes to Fermenter, Biomass into Distillery and Ethanol into storage + Liquid burning boxes used by Fermenter/Distillery.

Ethanol setup


Even the sideproduct (Distilled water) is situationally useful. You can use it to simplify the existing boiler configurations, as Distilled water does not cause calcification.

  1. Oil

Naturally, our base grew and our power needs skyrocketed when most of the machines were up-tiered from bronze era. Old boilers were being smelted and repurposed as different machines. Ethanol was becoming more scarce, even with expanded farming space. This prompted us to go through the “Engine Fuels” crafting recipes, and this is where we found out about oil products.

Oil is the major component when advancing in GT6 tech tree. It is required for plastics and has awesome yields for power production: Butane and Propane in gas form, Petrol, Kerosine, Diesel and Fuel in liquid format. Last 4 are fully compatible with Diesel engines. We used oil extensively throughout LV, MV and HV eras.

Black gold

Following underground oil deposit yielded us around 12-15 full barrels of heavy oil (heavy produces more liquid products, light more gaseous products). Oil was collected by placing and powering a Rotational pump on the bottom of oil deposit.

Oil is processed in the Distillation Tower, and its many, MANY outputs are quickly transferred to buffer drums.

  1. Natural Gas

This is more niche setup than Ethanol and Oil, but very powerful nonetheless. You can sometimes find strange white spots on the bedrock that irregularly output white gas. This is a Natural gas deposit. We got extremely lucky and found a large deposit (10-15 blocks that output gas) near our base. By surrounding the blocks and leaving them room to move towards single center target you can collect all of the gas being produced. Beware: natural gas flows upwards! Rotational pump can gather the gas.

  1. Gas Turbine and Coal Gas production line

As some of you might have noticed, mentioned methods rely heavily on the liquid fuels to produce EU/t power (Diesel engines → Electric dynamos → Battery boxes). We had few steam-producing setups with Gas Burning boxes, but these were too cumbersome for extended usage. By following the crafting recipes you’ll eventually end up finding the mini-bosses of GT6: Turbine and Dynamo multiblocks.

These are extremely powerful but equally hard to make. Each full multiblock requires thousands of units of highly processed materials (Stainless steel, Magnalium alloy, Annealed copper). After we understood the scale of these monsters, we actually created automation setups for producing each of these materials (more on that in the next post). For now, let’s have a look at completed Gas-consuming and EU/t producing setup.

4.1 Magnalium Gas turbine and Stainless steel dynamo

Magnalium Gas turbine produces maximum of 8192RU/t, which is also the maximum input of Stainless steel dynamo (turning 8192RU/t into 6144EU/t). This setup is simple and very easy to understand: If you input compatible gas into Gas turbine, you’ll get out steady output of 6k+ EU/t. By converting the output from IV to EV energy (Transformer EV-IV) you can output the EU/t into Battery box filled with batteries. Waste (Water and CO2 Gas) are voided from the side of the multiblock.

Early setup

After time passed, we made improvements to the design: automatic activation logic and backup Diesel generator cluster.

Current setup and backup Diesel cluster

If battery box energy level goes under around 50% of the maximum, redstone signal will reach the main turbine activation line (also hand-activatable through a level). Under 40% energy level causes redstone signal to reach the end of the logic panel, causing backup Diesel cluster to fill up with fuel (producing steady power output for around 5 minutes)

Diesel cluster produces total of 12x88 = 1056EU/t using liquid fuels. Good for jump-starting energy network if you run out.

For a time, all was good. Natural gas, oil products and ethanol were used, energy network was kept at full and multiple high-tier machines could be run simultaneously. But the cracks were quick to appear: shuffling between different raw materials took time, running between natural gas deposits took time and finding oil took time. As our base grew even larger problems became even more apparent. No, this could not go on. And the search for better energy generation methods continued.

“hey, we saw that coal gas at some point, would that work?”

Yes. It would work nicely.

4.2 Coal Gas production line

Coals gas is an excellent fuel for late game power generation, as it is very simple to make. Only things you need is Anthracite Coal ore, some water and crapload of machines.

Coal Gas production line

First phase is to get the Anthracite coal into processable form. This is accomplished with Crushers, Shredders and different buffers combining and uniting items. Note: We were not sure how GT6 overclocking mechanic worked (allows recipes to be processed at 2x speed but with 4x energy consumption, doubling the energy usage). To be sure we were not “losing” efficiency in the process that it matters the most (energy generation), we used low-tier bronze machines to prevent overclocking from happening.

Next up is the Liquefaction process, handled by Burner Mixers. Second phase has a quirk that needs a bit of attention: Burner Mixers require you to light up the mixer or the processing will not start. To prepare for this, we created Automatic Igniters (LV) and placed them towards the mixers. Igniters are always active, and we decided to add “Auto reboot cover 5mins” cover to each of them, meaning that igniters would be activated (and would try to ignite mixers) only once every 5min. Not a perfect solution, but has worked fine for few hundred thousand dust processing cycles.

Last step is to insert the Liquefacted Coal into Distillation Tower (Yes, we constructed another one just for this processing phase), activate it and reap the results. Some small-scale logic was used, e.g. “try to ignite Dense Liquid Tantalum Hafnium Carbide Burning box when the Distillation Tower input is full” but nothing too fancy. Liquid fuels created by this last phase are used to power every phase of the Coal Gas production, making the whole process to work as “add coal, forget and collect”. Little stress, huge rewards.

There we have it, power generation used in TPSServer. I decided to omit solar power, water power and other experimental methods (even though at least solar power is being used here and there). And to note, Coal Gas is not the end-of-line method. As I think everyone knows, there are still some methods that are vastly more powerful and equally more destructive to come.

For a teaser, next post will go through intermediate contraptions, supporting machinery and logic-driven Crucible setups. Here’s a picture from the -1 floor of our multi-level processing chunk, named “The Pitt”.


You can collect natural gas with just a vent cover. No pump needed.


And by that you mean DRAIN Cover. :stuck_out_tongue:

Yeah, I’m always mixing those up.


GT6 Item Pipes! They auto-route and are less laggy and all! Plus there are long-distance versions that are lagless along those runs!

Still though, these posts you do are awesome! Keep em coming! ^.^
