Question about the new "behemoth" chemical plant

[DaveOath]

The building description says the "consumption at maximum production" is 168 MWh, and the "max power consumption" is 197 MWh.

Does this mean the building needs 197 MWh on its own, and the industrial process needs an additional 168 MWh for a grand total of 365 MWh (So, you need a line to carry 6MW of electricity to several substations.)?

[T600_Mod]

is this a new mod that just came out? sometimes its just best to build a power plant beside a building that requires that much power.

[T600_Mod]

Is that the 700 Worker Vannilla one? if so a few substations should do, but I suggest downloading the Hazardous Chemical Plant in Workshop

[Strategic Sage]

They are referring to the vanilla chemical plant. I don't know the answer to the question, I don't know enough about power yet, but there are many other buildings that have the different values.

In a case like this, I think an explanation from someone with more knowledge about what the power mechanic is, is appropriate. Download a mod is not always the solution, esp. since some players prefer to play without mods and that isn't what the question was directed towards.

[DaveOath]

Yes, I'm referring to the new vanilla chem plant (9.4t/d). Introduced in the last update.

iirc the max power consumption is the absolute max that building will draw and includes production as well as loading/unloading from vehicles and any other possible uses the building has for power.

For a better understanding just always look at the Max Wattage (circuit breaker) data, in this case is 3.30 MW.
It is all you want to know, and that means to provide in this case for the max. production.

Apart from production itself it can be additional consumption from for example loading/unloading trucks ...and trains etc. But circuit breaker will cover all with much more than enough (you won't usually use all loading stations at full load and at the same moment for example)

Good point.

Btw, under which circonstances you can trigger a circuit breaker? Dont think it ever happen to me.

May be a power plant get "override" by too much consumption, I guess. But it is just a name, it will just not produce more than that or consume more than that, and that is all. AFAIK

Had only one substation since start and never had issue for stopping due to power. Now I have two since I build some other things around, but I doubt you need something like "multiple" ones. Would be nice for it to have own electric connection though

its own electrical connection might be useful., but it seems fine. But I would have liked multiple rail connections, albeit you could link that, altho they could have covered for workers and material, as well as chemicals.

Waste can be something that you need to deal with as well.

There is not really a circuit breaker, it's just the amount of power the building will pull when working at max capacity, if there is not enough supply there will be electricity problems (voltage drop) on the infrastructure that supplies electricity to the building.

To clarify the other comment's point:
MW = power
MWh (Megawatt-hour) = *energy* (which the game confusingly also calls power...)
max MWh per day = 'circuit breaker power' x 60 (because a game day has 60 seconds, not 24 hours...)

It can be tricky to get the large chemical plant working at full capacity - not only wrt supply of workers, but also it can be bottlenecked by water supply; max 119 cubic meters per day (requires a big water pipe and matching water well capacity), and capacity of waste water disposal (something it the range of 100 cubic meters per day, needs big sewage pipe). If you want to treat the waste water it takes a significant fraction of the capacity of a large sewage treatment facility (about 30% or so).

When it does work at full capacity it needs two electric substations to supply enough power.

I have a complex with two large chemical plants, 3 plastics factories, 1 liquid fertilizer factory, + associated buildings (pumps etc), and a dedicated large sewage treatment with its own waste water outlet. 3 small water wells to supply enough water.
At first there were all kinds of problems with electricity supply, water supply and waste water disposal. It ended up with five electric substations and its own power transformer which pulls up to like 7MW when everything runs at full capacity.

Yes it's odd that the large chem plant has only one rail connection, while the steel mill - which smaller in every way - has 3 rail connections.

Agree.
I had been using one from the workshop, that has four rail connections. That being a large chemical plant.
This one looks wonderful, but the lack of rail.....


EDIT: Just considering adding rail to then find one set of rails has been added :)

Wonderful.

Is it really that odd, though? When it comes to the transportation infrastructure you need to have in order to sustain a factory, the physical size of the plant doesn't matter nearly as much as the volume of material you have to ship to or from the plant, and the steel mill's input requirements are around an order of magnitude higher than those of the large chemical plant even if you're moving everything the chemical plant needs by rail but only doing the same for one of the steel mill's two inputs. Looking at it another way, the large chemical plant has sufficient internal storage to keep itself operating at rated capacity for ten to twenty workdays without deliveries; the steel mill, by contrast, has sufficient internal storage to keep itself going at rated capacity for less than one workday (less than half a workday, even, comparing coal storage to coal consumption).

One of these things requires significantly more transport capacity to sustain it than the other, and it's not the large chemical plant.

The workshop one allows delivery of all the needed goods and then workers. On such a large capacity, material and workers, factory, it needs to have that option. Ideally within one set of rails and not needing two types of additional stations.
Perhaps more so now due to the greater needs for chemicals.

Operating at rated capacity, the large chemical plant consumes 41.3t of material (8.4t gravel, 9.8t wood, 9.1t crops, 14t oil) per workday while producing 9.4t of chemicals and ~10t of trash. Even if you move literally everything by rail, that's only about 60t of material you need to transport per workday; a single rail connection can easily handle that, and there's plenty of internal storage for most of it at the chemical plant (around 10 to 20 workdays of input storage and around 5 workdays of output storage, not counting trash) so, even slotting in some passenger trains to deliver 700 workers per shift, there shouldn't be much of a capacity issue regardless of whether you want to run separate trains for each unique resource or a single mixed-consist train to handle everything or anything in between.

The steel mill, by contrast, needs over six hundred metric tons of shipping capacity per workday while also needing 500 workers per shift. The steel mill having three rail terminals while the large chemical plant has only one is entirely justified.

[Silent_Shadow]

Even with three tracks, it is still very difficult to supply the steel mill with just trains.

[bspawn]

Fair points about the resource requirements of the steel mill vs chem plant.
I guess i'm happy mine are not operating at anywhere near full capacity - especially the steel mill. Even then i find it needs a large external coal storage and benefits from having a conveyor connection to the mining and processing chain.
